Introduction
A wastewater treatment service is an innovative model where companies can outsource the entire management of their wastewater treatment. Wastewater treatment as a service is a modern approach to wastewater management, offering a multitude of benefits for industrial facilities. This service model is analogous to how businesses outsource IT services, logistics, or even human resources. Wastewater treatment enzymes are used to treat effluent before they are discharged so that the environment is not polluted. It includes the treatment of suspended, floatable material and the treatment of biodegradable organics, and also contributes to odor removal. The increasing demand for water in chemical & pharmaceutical, food & beverage, pulp & paper, oil & gas, and power generation is driving the wastewater treatment services market. Implementation of a sustainability approach and green practices through reduce-recycle-reuse is escalating market growth opportunities for wastewater treatment service.
