Product Details:

Polyacrylamide High Molecular Wt is an anionic charged solid polyelectrolyte designed to be used as a flocculant in the direct filtration process for settling of inorganic suspended solids, effluent water.
It is used for effluent treatment of inorganic suspended solids found in breweries, beverage, chemical, fishery, food, textile, dye, other effluent water, mining and coal washing waste water, metal processing industries, etc.
Polyacrylamide, in its ionic form, is found to be having a major role in the potable water treatment industry. Trivalent metal salts like aluminum chloride and ferric chloride are bridged by the long polymer chains of polyacrylamide. This leads to significant enhancement of the rate of flocculation. This allows water treatment plants to improve the removal of total organic content (TOC) from raw water to a great extent.

Wastewater is any water whose quality has been adversely affected by human activity. Wastewater can begin from a variety of sources such as residential, industrial, business, or agricultural activities, etc. Depending on the source, the composition of wastewater ranges from mildly polluted stormwater runoff to toxic wastewater from chemicals, pharmaceutical, and metal industries. The presence of pathogens, organic and inorganic matter, suspended particulates matter, dissolved gases, paint emulsions, pesticides, bio-solids, and many more undesirable substances can impair the quality of water. Industrial wastewater serves as one of the important pollution sources that add up to polluting the water environment. The sewage sludge produced is subjected to sludge treatment. Many problems are associated with wastewater collection and treatment such as foaming, solid accumulation, high BOD, sludge de-watering, heavy metals, and offensive odors. Chemtex Speciality Limited is an esteemed manufacturer of Wastewater Treatment Chemicals that meets all the standard requirements, and more, also helps in the removal and elimination of harmful pathogens, and bacteria, taking out hazardous chemicals, detergents, and toxins from the wastewater. Our product line includes Coagulants, Flocculants, Antifoams, decolorizers, Odor control Chemicals, etc.

Product Details:

Chemtex Effluent Treatment Flocculants are substances that promote the agglomeration of fine particles present in a solution, creating a floc, which then floats to the surface (flotation) or settles to the bottom (sedimentation). This can then be more easily removed from the liquid. We provide a range of polyelectrolytes of different molecular weights such as low molecular weight, medium molecular weight, high molecular weight, and ultra-high molecular weight, and ionic charges such as anionic polyelectrolyte, cationic polyelectrolyte, non-ionic polyelectrolyte, and amphoteric polyelectrolyte. All these flocculants are used for secondary settling and sludge dewatering. For primary settling coagulants such as alum, PAC (poly aluminum chloride), ferric chloride, ferrous sulfate etc are used and from the organic range products like poly DADMAC, polyamine, and poly DCDA are used.

Key Features & Benefits

• Easy to use
• Environment – friendly
• Enhances rapid sludge settling
• Improve sludge dewatering stags and results In improved effluent output
 • Cost-effective

Product Details:

Polyelectrolyte is a strong polymer based coagulant specifically designed for partial or complete settling of organics, water soluble matters and suspended solids in the effluent or waste water through electro neutralization and bridging absorption. Bridging absorption occurs when long chain polymers get absorbed on the particles in a pattern such that it forms loops and tails extending some way in the solution. At this stage, particles are said to be restabilized. Absorbed amount must be optimum otherwise enough bridging contacts couldn’t form. This consideration results in the necessity for an optimum dosage of the product for formation of bridging flocculation.
Polyelectrolyte can be differentiated into 3 types based on the charge present on it. These are Anionic Polyelectrolyte, Cationic Polyelectrolyte and Non-Ionic Polyelectrolyte. Flocculation generally occurs due to these charges present on the particles. In practical cases, charges are present on the impurity particles and electrostatic interaction occurs between these particles and polyelectrolyte.
Polyelectrolyte, offered by Chemtex Speciality Ltd. is a high performance flocculant, decolorant, and effective in algae growth inhibition and organics removal. It usually enjoys a small dosage but can be able to cause big flocs, rapid precipitation and low turbidity residues. It finds applications in variable sectors such as water treatment, textiles, cosmetics, mining, paper making, soil treatment, oil industries etc.
