Grab Style Trash Rakes For Water Intake Debris Removal

Grab Rakes - sometimes called fish rakes - remove large debris from raw water intake systems at power plants and other industries that use large volumes of raw water for cooling.

The Evoqua Grab Rake is ideally suited for cleaning bar racks at cooling water intake structures, municipal water intake structures and small low-head hydro power stations. Sometimes called a fish rake, this equipment is an industry's first line of defense against logs, leaves, sticks, litter and other large floating debris.

The Grab Style Trash Rake from Evoqua is designed to easily engage the bar rack to collect debris as it descends down the face of the rack.  Debris is then removed during the rake's ascending run and placed into deck-level receptacles.  The Grab Style Trash Rake is considered to be the first line of defense in efficiently removing debris, ensuring that downstream screens, pumps and other equipment are protected, thus providing uninterrupted clean water flow to your plant.

Keep debris from flowing into your manufacturing or power facility. Evoqua is the OEM for these grab rake brands: USFilter and Envirex. Our grab rakes are also called fish rakes and trash rakes. Fish are able to swim through our grab rake bars and be put back into their habitat with our traveling water screens for fish protection. Evoqua intake equipment helps keep fish and debris out of your cooling water and clean water in - we are your best choice for clean raw water.
