Sewage Treatment Plant STP Companies in Kerala India, STP Suppliers as per Pollution Control Board norms in Kerala

We offer technically advanced Sewage Treatment Plant, which is used to treat large amount of sewage effectively. With a combination of several steps, our Sewage Treatment Plants treat the toughest sewage without using much power. The designing of the Plant is done by experienced personnel to make them ideal for repetitive usage. Green Water Science focus on conventional treatment plants as well as microbial treatment process which is eco-friendly and avoid the usage of chemicals which in turn result in reduced sludge. Compact sewage treatment plants can be streamlined for different stages of treatment such as aerobic treatment, extended aeration, activated sludge process, etc. Our engineer’s works closely with the clients to provide cost-effective solutions for their specific needs.

During primary treatment, waste water is screened for the removal of solids, grit and primary sedimentation. The filter water is chlorinated for disinfection. Part of the wastewater is subjected to secondary treatment, which utilize special strains of aerobic bacteria (bacteria that need oxygen to grow) to break down the organic waste left after primary treatment. Secondary treatment process removes up to 95 percent of suspended solids in the waste stream and is significantly more effective than primary treatment in removing biologic pathogens from sewage. We also provide prompt after sales services for trouble shooting and maintenance of the installed systems.
