Types of Waste Water Treatment

There are many ways to treat industrial wastewater. The contaminants are reduced or eliminated with high-grade equipment so that the remaining effluents, or sludge, can be safely disposed of.The wastewater is reduced in quantity and made safe to reuse or recycle back into the environment through our waterways. Here are some of the more common wastewater treatment types. More than one treatment method may be necessary, depending on the type of wastewater and the industry that produced it. CPI Separators Corrugated plate interceptor separators (CPI Separators) are machinery that is mostly used is an effluent treatment to separate oil or suspended solids from the water. They are commonly used by oil refining companies and are a highly safe and efficient method of removing oil from water. In the treatment of oily water, plate packs are used in the CPI separators to improve the economy and size of the separation system. Dissolved Air Flotation (DAF) Dissolved air flotation (DAF) is a method of treating waste water which...
