Effluent generated from factories, industries need to be treated before being discharged in water bodies,rivers and oceans. Customised solutions is required to treat such type of effluents, It can be a physio-chemical process , biological treatments , membrane separation to meet the desired results . We have the expertise and capability to design install and commission such systems for waste from industries like Tannery , Pharma, Electroplating Refineries, Diary ,Dyeing etc.
Due to rapid urbanization and very high density of developed cities, it is difficult for civic authorities to provide necessary infrastructure facilities such as water and sanitation. Rapid development of the suburban areas and lack of treatment facilities .Seeing the need to have decentralized sewage treatment plant known as package STP’s for small town ships, hotels, restaurants in their premise. The benefits of establishing decentralized STP’s or package plants is reduction in foot print reduces soil pollution due to infiltration , the package wastewater treatment plant is a perfect fit for any medium size institution ,factory society.
Electroplating wastewater comes from surface plating operations where the metal is dipped in an electroplating solution of various types of metals and then rinsed. It includes metals like brass, nickel, cadmium, zinc, silver, copper, and gold. wastewater is typically generated from washing, rinsing and batch dumps and with low pH ranging from 2-5 and contains soluble forms of the various metals. In order to remove soluble metals from the wastewater it must first be made insoluble. The insoluble metal is then coagulated, flocculated and clarified by sedimentation. Treatment steps include Precipitation—Coagulation- Flocculation-settling-Disinfection
The textile industries generate huge quantity of toxic effluent containing colours, sodium sulphate, sodium chloride, sodium hydroxide and traces of other salts. These are generated after dyeing and after washing of garments / fabrics. After dyeing the waste water produced is called Dye Bath water and after washing the waste water generated is called wash water. Dye Bath contains higher solids in the range 4-5% whereas wash water contains only 0.5-1% solids. Dye effluent has higher pH that needs to be neutralized for bacterial activity. The removal of excess acidity or alkalinity by a chemical agent is called neutralization. Industrial waters exposed to extremely high or low pH values require a neutralisation process before they can be sent to biological treatment or environment.
The dairy industry involves processing raw milk into products including milk, butter, cheese,yogurt, using processes such as chilling, pasteurization, and homogenization. Typical by-products include buttermilk, whey, and their derivatives. Huge amounts of water are used during the process ( cleaning requires 1:3 ratio) producing effluents containing dissolved sugars and proteins, fats, and possibly residues of additive.
