Product Information

We offer a variety of technologies for feeding and metering dry chemicals commonly used in the treatment of municipal and industrial water and wastewater as well as industrial process water and wastewater.

Our extensive line of volumetric screw and belt-type volumetric and gravimetric feeders, feeder tank systems, lime-slaking systems and accessories can handle the most commonly used chemicals in the municipal water applications such as calcium oxide, calcium hydroxide, ferric sulfate, soda ash, potassium permanganate, aluminum sulfate, and carbon. Chemicals used in industrial processes include bleach, clay gypsum plastic pellets, pigments, and flour.

This highly adaptable feeder features a variable speed feed screw with 3 different control arrangements: Manual control via a feeder mounted potentiometer; Start-stop control from a remote interlock; mA control from a flow signal or remote plant control.

Each of these feeders is available with a complete range of configurations and accessories.
