A dosing tank is a tank in which sewage is collected and later discharged at the rate required by subsequent treatment processes.
Our dosing tanks are seamless and made from UV stabilized Polyethylene. Kwerk Dosing tanks are safe for food processing and with a high chemical resistance. Kwerk dosing tanks have a seamless design and are made to high quality standards. The dosing tanks are also available with electric agitator. PE dosing tanks produced in a rotation process.

Kwerk dosing tanks are a safer and more effective solution for storing and dosing chemicals. Polyethylene material will not corrode, as opposed to other storing methods which will wear away over time. Furthermore Kwerk dosing tanks prevent gassing off on pump suction lines by inserting suction lines at the base of the tank. Kwerk GmbH metering pumps, suction lances and stirrers can all be added.
