ChemFeed

Chemicals are commonly used in the treatment and disinfection of drinking water. Common applications include coagulation, flocculation, pH control, corrosion control, and sludge dewatering. Water treatment chemicals are commonly available as a liquid, a solid, or a gas. Most chemicals are fed at fixed doses, and therefore requirement precise metering equipment to proportion the chemical to the water treated. Liquid feed system use positive displacement-type pumps like diaphragm metering pumps, gear pumps, progressive cavity pumps, and peristaltic pumps. Gas feed systems use automatic control valves to metering the gas to a side stream of water prior to injection. Solid feed systems use volumetric screw feeders, gravimetric screw feeders, or load cells to achieve their accuracy.
