Water Treatment

Whether it is the removal of oil and grease via an oil water separator or pollutants and settleable solids using an oil/sand interceptor, East Coast Associates has the experience to help you determine the right system for your specific site requirements. Our extensive knowledge of wastewater and storm water treatment systems can help facilities comply with the EPA’s NPDES regulations for the proper treatment and discharge of water and SPCC requirements for spill control and secondary containment.

Oil water separators are designed to remove oil, grease, light petroleum products and oily coated solids from a variety of wastewater discharges. They are typically installed in industrial areas and receive oily wastewater generated during processes such as bulk petroleum storage and handling, aircraft and vehicle fueling, and maintenance and washing operations. The separators contain specially engineered baffles and coalescers to accelerate the separation process. With the successful design of over a thousand installations, East Coast can help choose from a variety of design options and an extensive range of accessory packages.

Oil/Sand interceptors are wastewater treatment tanks designed to intercept and collect sand, grit and other pollutants as well as hydrocarbons and prevent their entry into the sanitary sewer system. Designed to accept gravity flow, the interceptor separates materials from the water using differences in specific gravity combined with a lengthy retention time.
