Pentair Aquatic Eco-Systems has announced the launch of the Eco-Trap, a dual drain waste

collection system designed for removal of settle-able waste solids (uneaten feed and feces) in Recirculating Aquaculture Systems (RAS).

            The Eco-Trap system is designed to pull solids to the middle of the tank where they are removed through the center drain and move collected waste materials through a side-stream drain to a polyethylene waste collector mounted on the side of each tank using approximately 5% of the total flow from the tank.

            According to the company, using the Eco-Trap technology will reduce the size and complexity of other solids removal technologies such as drum-screen filters and bead filters and the waste collector allows for easy observation by the farm operator leading to greater control over feed waste to individual tanks and providing a mechanism for controlling one of the single largest economic inputs to RAS aquaculture. The Eco-Trap system contains no moving parts and nothing to wear out and it has been proven in many commercial RAS installations worldwide. Visit for complete information.
