In a sewage treatment plant, waste or contaminated substances are treated with various means and produce purified substances that are safe and reusable in the process or discharge to the environment.

Without the correct treatment plant, an industry can suffer from scale formation, corrosion, fouling in the cooling system, and it may be a source of harmful bacteria. The proper conditioning of water can increase efficiency, span plant life, and plant safety.

The effluent treatment facility is installed for biological treatment of the effluents. The effluent bears large amounts of organic matter. The direct discharge of the effluent into the water bodies causes depletion of DO of the water. Hence, in order to meet the recommended standards of quality of the effluent, it is necessary to treat the effluent before it is finally disposed of. This treatment facility provides for the removal of major pollutants from the effluent. The heart of this treatment scheme is the aerobic biological reactor, which is designed on the basis of the activated sludge process. The activated sludge treatment process basically involves the stabilization of organic matter by the action of various microorganisms as depicted in the following equation.

Water Disinfection


There are many factors when looking for a groundwater treatment solution. What treatment will prove to be the most effective, whether biological, chemical, or physical, depends on site conditions, contaminant types, and concentrations. In addition, budget, timeframe, and other factors will impact which treatment approaches are selected. At Kohsa, we understand the complexities involved. Our team will work with you to explore all the possibilities and provide turn-key support to arrive at an effective solution.

Zero liquid discharge (ZLD) is an engineering approach to water treatment where all water is recovered and contaminants are reduced to solid waste. While many water treatment processes attempt to maximize the recovery of freshwater and minimize waste, ZLD is the most demanding target since the cost and challenges of recovery increase as the wastewater gets more concentrated. Salinity, scaling compounds, and organics all increase in concentration, which adds costs associated with managing these increases. ZLD is achieved by stringing together water treatment technology that can treat wastewater as the contaminants are concentrated. Regardless of an organization’s motivations to target zero liquid discharge, achieving it demonstrates good economics, corporate responsibility, and environmental stewardship. By operating an in-house ZLD plant, disposal costs can be reduced, more water is re-used, and fewer greenhouse gases are produced by off-site trucking, which minimizes impact on local ecosystems and the climate.
