Environmental Processing Equipment
Clean water continues to become a more precious commodity each day. The treatment of water and wastewater requires separation of solids from liquids. These solids are grit, screenings, sludge or bio-solids. KWS Grit Classifiers, Shaftless Conveyors can be found at hundreds of municipalities handling these bulk materials. Centrifuges and belt filter presses are most commonly used to dewater the wastewater. The sludge or bio-solids are conveyed with KWS Shaftless Conveyors to drying, load-out or incineration. Our unique designs work great for the wet, sticky products. Also, our vapor-tight construction reduces the odors produced by these products and the chance for explosion.
