| Poly aluminium chloride (PAC) is an industry standard primary alumunium based coagulant used for the treatment of drinking water, sewage and industrial effluents and is also a well established paper processing aid. It is a highly charged polymerization of aluminum ions and colloidal particles in water with high efficiency and power in bridging flocculation function. Effective water purifier used in the purification of table water, industry water, industry circulation water and wasted and polluted water from pharmacy industry, paper making industry and printing and dying industry, as well as life wasted water. Key Attributes and Benefits: • Economical • Faster flocculation • Reduces polyelectrolyte requirement • Removes heavy metals and radioactive substances to water pollution • No added alkaline additives • Suitable at a wide PH value • High stability • Quick hydrolysis • Strong absorptivity • Quicker precipitation • Low turbidity • Superior dehydration property Applications: • In-Line coagulant / use in ultrafiltration process in water treatment • Coagulant for waste water with reactive dyes • Used after alum flocculation of channel feed water at household level • Removal of suspended particulate matter and organic contaminants |

| 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. |

| Chemtex Speciality Limited manufactures a varied range of chemicals that are used for the effluent treatment, amongst which Flocculants Chemical has a crucial role. Flocculants Chemical is formulated specifically to be used in the effluent treatment processes for helping in the removal of solids, lime softening, water clarification, solids dewatering and sludge thickening. Flocculants Chemicals are agents that promote flocculation by causing colloids and other suspended particles in liquids to aggregrate and forming a floc. This product helps in improving the sedimentation or filterability of small particles. Flocculants Chemical include three variants of products depending upon their properties and the application of use. These include - Anionic, Non-Ionic and Cationic Flocculants Chemical. |

| Sewage can be regarded as a mixture of domestic and industrial wastes that is more than 99% water comprising of some ions, suspended solids and harmful bacteria. A major carrier of disease and toxins, treatment of sewage is important for the health of any community. Sewage Treatment includes removal of these impurities before the water is released into the sea. Chemtex Speciality Limited manufactures a range of Sewage Treatment Chemical that aid in treating Sewage water through the various steps that are followed during the treatment. Key Attributes and Benefits: • Helps in the breakdown of organic matters • Effectively helps in separating the waste solids from the water • Efficient in removing overall impurities |

| Effluent treatment chemicals consist of coagulants and flocculants. While the Coagulants essentially function for primary settling of suspended solids, the Flocculants perform for the secondary settlement of particles. While Coagulation is done with the help of Alum (Ferric / Non-Ferric), Ferrous Sulfate, Ferric Chloride, PAC (Poly Aluminum Chloride) etc.; Flocculation is done with Polyelectrolytes such as Polyacrylamides (Anionic, Cationic and Non-ionic), Polyamine, PolyDADMAC etc. 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. The selection of these flocculants is based on the type of application, system parameters and the type of effluent. The Coagulant is ideally utilized in divergent industries for the process of flocculation. |
