Product Overview

The screen is constructed of all non-corrosive materials, is a rear cleaning design with multiple rakes that travel up the screen and discharge over the back into a conveyor or a receptacle provided by the Owner. The design is very simple but effective, there is no wiper or spray system required to remove the screenings from the bars and all the items that eventually need replacing; bearings, chain, rakes, drive unit are bolted connections making replacement very easy. The screen components have a 30,000 hour operating life (that is 7 years if the screen operates 12 hours per day) and Enviroquip provides a 2 year warranty from startup for parts and labor.

The trend in the wastewater industry is moving toward finer screening. The advent of Membranes is one driving force behind fine screening but there is also the need to keep more of the non-organic material out of treatment plants of all types.

Benefits

Removing screenings from the influent wastewater not only helps a treatment plants overall appearance but eliminates costly labor and parts to unclog and maintain pumps, aerators and keep other mechanical pieces of equipment in good working order. Enviroquip’s fine screen design is simple and effective requiring none of the routine maintenance required of other mechanical equipment.

The Enviroquip fine screen can be used for screening domestic waste ahead of MBR plants and conventional activated sludge plants or SBR’s, industrial wastes such as food and beverage processing and scum separation. The Enviroquip fine screen fills a void in the market place. Some of our screens are designed specifically for lower flow rates and the physical size and price of the screen reflects the lower flow rates. A lot of utilities that could not afford an automatic screen now have that opportunity. The screens can be retrofitted in existing treatment plants replacing manual or old mechanical screens.
