Coagulants and flocculants
Coagulation and flocculation are an essential part of raw water treatment as well as wastewater treatment. Coagulants are used in the pre-treatment stage to reduce the turbidity of inlet raw water so as to make it easier to treat further before its use in any industry or for municipal supply. In wastewater treatment, coagulants and flocculants chemically enhance primary treatment to reduce suspended solids and organic loads from primary clarifiers. This stage combined with secondary treatment helps in achieving treated water quality that is easier to reuse or to meet discharge norms with minimal further treatment. We offer a range of anionic, cationic, and non-ionic polyelectrolytes for the treatment of raw water and wastewater as well as for de-watering of sludge generated from the effluent treatment plant. Our coagulants and flocculants are used across sectors such as Textile, Steel, Dairy, Mining, Paper, Electroplating, Food, Hotels, and Municipal, to name a few.
Textile Industry Products
Textile wastewater contains dyes in combination with a variety of contaminants. As environmental legislation requires textile mills to treat their effluent to meet discharge limits, coagulation and flocculation play a vital role in helping the mills meet this requirement.
Dairy Industry Products
Food processing industries generate wastewater with high biological oxygen demand (BOD) and chemical oxygen demand (COD). Amongst food processing industries, dairy processing industries pose major challenges to treatment of wastewater on two counts – the volume of wastewater generated per day, and the volume of wastewater generated per liter of produced milk (0.2 to 10 liters wastewater per liter of produced milk). Wastewater is generated right from the receiving station through milk bottling, cheese, butter, and ice cream production sections. The most important organic materials in the wastewater are fat, lactose and proteins (casein). Cream, butter, cheese, and whey production sections are the major sources of BOD in wastewater. Dairy wastewater can be treated by adjusting the pH and using chemical coagulants. The role of coagulants in dairy wastewater treatment is that of de-emulsification (break fat-water emulsions formed due to the use of surfactants, cleaning agents and sanitizers in the process), precipitation, coagulation, and flocculation. This crucial treatment enables the dairy industry to meet its wastewater discharge norms or to afford further treatment of the wastewater for recycle or re-use.
Steel Industry Products
Steel manufacturing consumes large volumes of water across various processes and also generates wastewater containing salts, suspended solids, organic and inorganic compounds, among other contaminants. Chembond’s coagulants and flocculants play a crucial role in the treatment of this wastewater and in rendering it suitable for reuse. This not only reduces the ecological footprint of the industry but saves operating costs.
