In addition, it can be used to improve the efficiency of disk filters and flotators, and for cationization of fillers to provide maximal filler retention.
It is also used as a BOD/ COD reducer and as a color removal for high-color waste water from dyestuff industry.
PolyDADMAC
PolyDADMAC are the most commonly used organic coagulants in water treatment.
Coagulants neutralise the negative electrical charge on particles, which destabilises the forces keeping colloids apart. In water treatment, coagulation occurs when a coagulant is added to water to “destabilize” colloidal suspensions.
This product (technically named Polydimethyl-Diallyl-Ammonium Chloride) is cationic polymer and it can be completely dissolved in water.

Polydadmac
Polydiallydimethylammonium chloride (shortened PolyDADMAC or PolyDDA) is a homopolymer of diallydimethylammonium choride (DADMAC).
The molecular weight of polyDADMAC is typically in the range of hundreds of thousands of grams per mole, and event up to a million for some products. polyDADMAC is usually delivered as a liquid concentrate having a solids level in the range of 10 to 50%. It is a high charge density cationicpolymer.
The charge density makes it well suited for flocculation.
Properties
The polymer body contains strong cationic group radical and activated-adsorbent group radical which can destabilize and flocculate the suspended solids and the negative-charged water soluble matters in the waste water through electro-neutralization and bridging adsorption.
It is very effective in flocculating, decolouring, killing algae and removing organics It is use in latex waste clarification , oil-water seperation, iron congulation. The product enjoys small dosage but can cause big flocs, rapid precipitation and low turbidity residue, and it can also produce small amount of sludge. It is adaptable to wide range of pH value, between 0.5 and 1.4.
It can be widely used to treat source water and sewage water.
Water treatment coagulants are comprised of positively charged molecules that, when added to the water and mixed, accomplish this charge neutralisation. inorganic coagulants, organic coagulants or a combination of both are typically used to treat water for suspended solids removal.
In a colloidal suspension, particles will settle very slowly or not at all because the colloidal particles carry surface electrical charges that mutually repel each other. A coagulant (typically a metallic salt) with the opposite charge is added to the water to overcome the repulsive charge and “destabilise” the suspension.

Poly(dimethyldiallylammonium chloride) (polyDADMAC) assisted cellulase pretreatment for microfibrillated cellulose (MFC) preparation and MFC analysis
Microfibrillated cellulose (MFC) preparation was investigated by means of cellulase pretreatment aided by poly(dimethyldiallylammonium chloride) (polyDADMAC) as an additive.
The effect of polyDADMAC on the adsorption of cellulase onto the cellulose fibers, and the properties of MFC and MFC films are described.
The additive improved the adsorption of cellulase onto cellulose fibers.
Compared to the control, at an addition level of polyDADMAC of 0.789 ml g−1, the crystallinity, aspect ratio, the specific surface area of MFC and, the elongation at break and tensile strength of MFC films are increased, while the oxygen permeability coefficient of the MFC films is decreased.
The optimal conditions for preparation of MFC by cellulase pretreatment were: pulp consistency 10%, cellulase dosage 10 µ g−1, pretreatment time 16 h and 0.789 ml g−1 polyDADMAC.
In summary, polyDADMAC-assisted cellulase pretreatment enhances the efficiency of the cellulase pretreatment of cellulose fibers and improves the performance of MFC and the MFC films.
PolyDADMAC / PDADMAC / PDMDAAC / Poly diallyl dimethyl ammonium chloride
Polydiallyldimethylammonium chloride, also commonly polyquaternium-6, is a homopolymer of diallyldimethylammonium chloride.
The molecular weight of polyDADMAC is typically in the range of hundreds of thousands of grams per mole, and even up to a million for some products.
The coagulants :
There are two main families of coagulants :
● Mineral coagulants which are simple metal salts (FeCl3, Al2(SO4)2, …) and polymerized metal salts (PAC, PASS,…).
● Organic coagulants which include polyamines, polyDADMACS, dicyandiamide resins andmelamine formaldehyde resins.
1.1.1. Characteristics :
The two key characteristics of organic coagulants are :
● A very high cationic charge density to neutralize the negative charges present on the surface of the colloidal material.
● A relatively low molecular weight to allow good diffusion of the cationic charges around each particle and, due to their low viscosity, good distribution of the coagulant in the effluent.
Organic coagulants are usually in liquid form with the exception of polyDADMACS which can also be produced in a solid form (polyDADMAC beads).
The viscosity of the liquid form is quite low (< 2 000 centipoises) but can reach 20 000 centipoises with concentrated polyDADMACS.
Concentrations in active material are between 8 and 70% (except for the polyDADMAC beads which are 100% active) with common concentrations between 40 and 50%.
The lowest molecular weights are obtained with the dicyandiamide resins (between 3 000 and 150 000) and the highest with the polyDADMAC beads (up to 2 500 000).
The coagulants, whether mineral or organic, have active groups : cationic charges (+).
These cationic charges offer a high degree of affinity for the surface of very fine and colloidalparticles in suspension in the water that are surrounded by opposite electrical charges (-).
The cationic charges supplied by the addition of coagulant contribute towards the reduction of the repulsive electrical forces through the neutralization of the charges around each colloidal particle.
This neutralization of the charges leads to a destabilization of the very fine particles, which results in an agglomeration of the particles. These agglomerates are then called flocs or microflocs.
The flocs, which are composed of a large number of elementary particles, will be easier to extract from the treated suspension.
Use and dosage :
Coagulants are used after dilution. The rate of dilution will depend directly on the parameters of the solution to be treated (concentration, viscosity, …) and on the application equipment(pump, flow, …).
Direct injection of the coagulant can be considered, although a previous dilution between 0.5 and 10% is recommended.
The dosage of the coagulant will be a function of the number of charges to be neutralized in the medium, therefore on the concentration in colloidal particles in the water to be treated.
Other parameters also influence the dosage such as:
● Agitation : good dispersion of the coagulant in the solution to be treated is necessary for all the charges surrounding the colloidal particles to be neutralized (Flash mixing with a speed gradient of 1 000 s-1 is recommended).
● Dilution of the coagulant : the more the coagulant is diluted, the better the dispersion in the water to be treated and therefore the better neutralization of the charges.
Use and dosage :
The flocculants must be completely dissolved before use. This dissolution depends on the commercial form :
● For products in solid form : after good dispersion of each grain separately in the water, agitation for approximately one hour is necessary for reaching maturation.
The agitation should be sufficient to maintain the product in suspension, but not too fast thereby avoiding the mechanical degradation of the polymer.
After maturation, a uniform, viscous solution should be obtained.
● For emulsions : violent agitation is necessary when the emulsion comes into contact with the water.
Maturation is quicker and the solution can be used immediately, however an aging time of some 10 minutes is preferable.
● For liquids : an in-line dilution with a static mixer is sufficient.
● We recommend active material concentrations of 1 g/l for the anionic flocculants and 3 g/l for the cationic flocculants.
A post-dilution is then often set up to facilitate the mixing of the flocculant and the solution to be treated, by reduction of the concentration and therefore of the viscosity of the flocculant solution.
Notes :
● The solutions, even diluted, are extremely viscous. The viscosity of a flocculant solution is mainly linked with its molecular weight.
● Polymers are sensitive to mechanical degradation (agitation).
● The grains tend to agglomerate if they are not correctly dispersed.
● These products spread over damp surface are extremely slippery.
● The dissolution speed of powders is affected by
- ionicity,
- particle size,
- concentration,
- water temperature.
● Dissolution time for non-ionic powder flocculants may reach 4 hours.
● The solutions of cationic flocculant are not very stable over time (hydrolysis phenomenon) due to the hardness of the water and a fresh solution should be prepared each day with a control of the solution’s pH.
A pH lower than 5.5 is recommended. All flocculant solutions are sensitive to Fe2+

Poly DADMAC can also be used as a flocculant to improve soap separation process in the evaporation plant of kraft pulp mills thus contributing to higher tall oil yield.
PolyDADMAC (PD) is a high charge density cationic polymer of diallyldimethylammonium chloride which has been recently developed as a coagulant in water purification. As PD has high affinity to fine negatively-charged colloids, it is worth to ascertain if PD can affect surface properties of clay-size particles in red mud waste and be applied to develop immobilization techniques for red mud storage areas. In the current study, a test tube method in combination with surface charge measurement was used for determination of the colloidal properties of a red mud sample under the variation of PD, soluble Al and Si, and variable pH conditions. Observations for the PD concentration range from 0.25 to 2.0?mM revealed that PD can increase surface charge and enhance aggregation or at least shift the aggregation zone to higher pH. This suggests a possible application of PD for immobilization of red mud in alkaline condition. It was also found that soluble Al and Si acted to modify the effect of PD and aggregation properties of red mud. While soluble Si supported aggregation, Al appeared as an enhancer for dispersion of red mud. It implies that development of PD-based techniques for immobilization of red mud needs to consider the effects of soluble Al and Si.
Polydadmac is used as a primary or secondary coagulant in clean and wastewater treatment, oily water treatment, organic material removal, organic dye removal, sludge dewatering.
Polydadmac is an organic polymer containing flocculating cationic radical groups and active adsorbent groups which destabilize suspended solids (AKM) and dissolved substances in water by electroneutalization and bridge absorption. It is used effectively for flocculation, decolorization, degreasing, organic material removal. In spite of low dose amounts, it provides rapid precipitation by forming a large diameter flock. It has a wide pH operating range. Odorless, tasteless and harmless compound.
Composition: The name of this chemical says it all. It is a linear homopolymer consisting of a quaternary ammonium and a monomer with two unsaturated -CH = CH2 functionalities. The monomer itself is formed by reacting two equivalents of allyl chloride with dimethylamine. Free radical polymerization of "DADMAC" monomers reveals a structure in which quaternary ammonium groups are on the rings in the backbone of the polymer chain. This composition means that the poly-DADMAC macromolecules are rather hard since they have a longer retention length than, for example, polyamines. Therefore, poly-DADMAC is expected to have a wider conformation in solution. The molecular weight of DADMAC typically ranges from hundreds of thousands of grams per molecule to even a million for some products. DADMAC is usually given as a liquid concentrate with a solid concentration of 10 to 50%.
- PolyDADMAC can be used as paper making, coating and antistatic agent, AKD sizing aid and retention and drainage agent.
- PolyDADMAC can be used for color removal, flocculation in water treatment (drinking water and wastewater).
PolyDADMAC can be used as a shampoo screening agent, wetting agent and antistatic agent in daily chemistry.
- PolyDADMAC clay stabilizer, acid breaking cation additive etc. In oil field chemistry.
When used alone, PolyDADMAC should be diluted to a concentration of 0.5-0.05% (based on the solids content). When PolyDADMAC is used to treat different source water or wastewater, the dosage depends on turbidity and water concentration. The most economical dosage is based on the experiment. The dosage place and mixing speed should be carefully determined to ensure that the chemical mixes evenly with other chemicals in the water and that the lumps do not break. It is better to constantly dose the product.
Kompozisyon:PoliDADMAC Bir kuaterner amonyum ve iki doymamış -CH = CH2 işlevsellikleri olan bir monomerden oluşan doğrusal bir homopolimerdir. Monomerin kendisi, iki eşdeğer alil klorürü dimetilamin ile reaksiyona sokmak suretiyle oluşturulur.PoliDADMAC monomerlerinin serbest radikal polimerizasyonu, kuaterner amonyum gruplarının polimer zincirinin omurgasında bulunan halkalar üzerinde olduğu bir yapı ortaya çıkarmaktadır. Bu kompozisyon, poli-DADMAC makromoleküllerinin, örneğin poliaminlerden daha uzun bir kalıcılık uzunluğuna sahip oldukları için oldukça sert oldukları anlamına gelir. Bu nedenle,PoliDADMAC 'ın çözeltide daha geniş bir konformasyona sahip olması beklenir. PoliDADMAC nin molekül ağırlığı tipik olarak molekül başına yüz binlerce gram ve hatta bazı ürünler için bir milyona kadar değişir. PoliDADMAC genellikle katı konsantrasyonu% 10 ila 50 olan bir sıvı konsantre olarak verilir.
- PoliDADMAC, yardımcı formaldehit olmaksızın yardımcı boyama ajanı olarak boyama ve apreleme işlemlerinde kullanılabilir ve kumaşta bir film oluşturabilir ve renk haslığını artırabilir.
- PoliDADMAC kağıt yapımı, kaplama ve antistatik ajan, AKD boyutlandırma yardımı ve tutma ve drenaj ajanı olarak kullanılabilir.
- PoliDADMAC, su arıtımında (içme suyu ve atık su) renk giderme, flokülasyon için kullanılabilir.
- PoliDADMAC, günlük kimyada bir şampuan tarama maddesi, ıslatma maddesi ve antistatik ajan olarak kullanılabilir.
- PoliDADMAC kil dengeleyici, asit kırma katyonu katkısı vb. Petrol sahası kimyasında.
Tek başına kullanıldığında, PoliDADMAC % 0,5-0,05 konsantrasyonuna (katı içeriğine dayalı olarak) seyreltilmelidir. PoliDADMAC farklı kaynak suyu veya atık suyu arıtmak için kullanıldığında, dozaj bulanıklığa ve su konsantrasyonuna bağlıdır. En ekonomik dozaj deney üzerine kurulmuştur. Dozaj yeri ve karıştırma hızı, kimyasalın sudaki diğer kimyasallarla eşit oranda karışmasını ve topakların kırılmamasını sağlamak için dikkatlice belirlenmelidir. Ürünü sürekli olarak dozlamak daha iyidir.
Polidialildimetilamonyum klorür (PoliDADMAC), Superfloc C-500 serimizin bir parçası olarak iyi bilinen bir diallildetilamonyum klorürün (DADMAC) bir homopolimeridir. Bu organik pıhtılaştırıcılar, farklı moleküler ağırlıktaki sıvı, katyonik polimerlerdir. Birincil pıhtılaştırıcı olarak etkili çalışırlar ve nötrleştirme ajanlarını yüklerler.
PoliDADMAC genellikle filtrasyon uygulamalarında veya topaklaştırıcı ürünlerimizle birlikte kullanılır. Bu polimerler birçok su arıtımı temizleme işleminde oldukça etkilidir. PoliDADMAC ve / veya katyonik poliaminler, genel işlem maliyetlerini düşürmek için topaklaştırıcı ve pıhtılaştırıcı ürünlerimizle birlikte de kullanılabilir.
Poli DADMAC, su arıtımında topaklaştırıcı olarak kullanılır. Topaklanma, renk alma, algleri öldürme ve humus gibi organik maddeleri çıkarmada çok etkilidir. Büyük disketler, hızlı yağış ve düşük bulanıklık kalıntısı elde etmek için çok az şeye ihtiyaç vardır.
TEMEL ÖZELLİKLER VE FAYDALAR:
PoliDADMAC (PD), son zamanlarda su arıtmasında bir pıhtılaştırıcı olarak geliştirilen, diallildimetilamonyum klorürün yüksek yük yoğunluklu katyonik bir polimeridir. PD, negatif yüklü koloitlere karşı yüksek afiniteye sahip olduğundan, PD'nin kırmızı çamur atığındaki kil büyüklüğündeki parçacıkların yüzey özelliklerini etkileyip etkilemediği ve kırmızı çamur depolama alanları için immobilizasyon teknikleri geliştirmek için uygulanıp uygulanmadığının tespit edilmesi önemlidir. Bu çalışmada, PD, çözünür Al ve Si varyasyonları ve değişken pH koşulları altında kırmızı bir çamur numunesinin kolloidal özelliklerinin belirlenmesi için yüzey yükü ölçümü ile birlikte bir test tüpü yöntemi kullanılmıştır. PD konsantrasyonu için 0.25 ila 2.0 mM arasındaki gözlemler, PD'nin yüzey yükünü artırabildiğini ve toplanmayı artırabileceğini veya en azından toplanma bölgesini daha yüksek pH'a değiştirebileceğini ortaya koydu. Bu, alkali durumda kırmızı çamurun immobilizasyonu için PD'nin olası bir uygulamasını önerir. Aynı zamanda, çözünür Al ve Si'nin, PD'nin etkisini ve kırmızı çamurun toplanma özelliklerinin değiştirilmesinde etkili olduğu bulunmuştur. Çözünebilir Si destekli agregasyon olsa da, Al kırmızı çamurun dağılması için bir güçlendirici olarak göründü. Kırmızı çamurun hareketsiz hale getirilmesi için PD bazlı tekniklerin geliştirilmesinin, çözünür Al ve Si'nin etkilerini göz önünde bulundurması gerektiği anlamına gelir.
Poli (diallildimilamonyum klorür) (PoliDADMAC), kloramin ile temas halindeyken olası insan kanserojen-nitrosodimetilaminin (NDMA) önemli bir öncüsü olduğu gösterilmiştir. Bu çalışmada, kloraminasyon sırasında, pH değerlerinin, amonyak, bromür, doğal organik madde (NOM) ve monokloramin dozajının PoliDADMAC'dan NDMA oluşumu üzerindeki etkilerini değerlendirmek için ortogonal bir deney tasarımı yaptık. Bu arada, tek faktörlü pH, bromid ve NOM deneyleri, ortogonal deney sonuçlarını kanıtlamaktadır. Sonuçlar, pH'nin kloraminasyon sırasında PoliDADMAC'dan NDMA oluşumunu etkileyen en kritik faktör olduğunu ve PoliDADMAC'den en yüksek NDMA oluşumunu, PoliDADMAC degradasyonundan salınan DMA ve sudaki düşük dikloramin konsantrasyonlarının kritik önemi nedeniyle 7'ye yakın pH'da gerçekleşti. Aşırı bromür varlığında, NDMA oluşumu, bromokloramin veya dikloraminden daha yüksek elektronegatifliğe sahip olan bromokloramin sayesinde, bütün farklı pH değerlerinde anlamlı şekilde arttırıldı. NOM varlığında PoliDADMAC'dan NDMA oluşumu, NOM yokluğunda NDMA oluşumundan% 41.7 daha düşüktü. Simüle edilmiş koşullar altında PoliDADMAC'den NDMA oluşumunun çok büyük bir kısmı mevcut danışma seviyelerinden daha düşüktü (yani, Ontario'da 9 ng, California'da 10 ng).
Polydadmak temiz ve atıksu arıtmada, yağlı su arıtmada, organik madde gideriminde, organik boyar madde gideriminde, çamur susuzlaştırmada birincil ya da ikincil koagülant olarak kullanılır.
