Waste Water Treatment

Our typical treatment plants consist of six individual tanks set up in series. Preliminary treatment removes large or hard solids that can clog or damage equipment downstream. This occurs at lift stations.

The first tank is the primary settling/equalization tank. The water flows slowly for up to a few hours to allow organic suspended matter to settle out or float to the surface.

The next four tanks involve secondary treatment where the remaining dissolved and/or coloidal organic matter is removed. Biodegradation of organic matter is allowed to take place here where plenty of air can be supplied to the microorganisms, promoting formation of the less offensive, oxidized products.

After sufficient aeration time, sludge is carried away into the settling tank. Disinfection is the final step before discharge. We use the Hallet 30 ultraviolet light disinfection method which passes the water through a cylindrical quarts sleeve surrounded by two high intensity UV bulbs. This method handles more difficult effluent requirements from waste water plants.
