A VALUABLE RESOURCE FOR THE CHEMICAL INDUSTRIAL PARK
Water is one of the most important raw materials used in the production and power plants at the Chemical Industrial Park Knapsack. It serves as a coolant and as an energy carrier in the form of hot steam. Demineralized water is used in various manufacturing processes.
The water used in the Chemical Industrial Park Knapsack is transported via our own supply pipeline leading from the water works in Erftstadt. In order to utilize this valuable resource as economically as possible, the water used is purified in an internal water treatment facility and reused. Cooling water is transported throughout the entire chemical park via a closed-loop pipeline system and cooled down again in our own recooling facilities through contact with the air. The water is therefore not contaminated and only a very small amount evaporates. In contrast to the one-off use of fresh water in households, we use our water more than 20 times.
WATER IS LIFE
But only when it is clean. One of the most important tasks is therefore to treat industrial waste water from the chemical park after use in the production process in such a way that it can be reintroduced with complete safety into the natural water cycle. This has been the task performed by Abwasser-Gesellschaft Knapsack GmbH (waste water treatment company) since 1929. On behalf of the waste water treatment company, InfraServ GmbH & Co. Knapsack KG operates two modern waste water treatment plants and an extensive sewer system at the chemical park. In addition, it provides a water protection officer for the companies on site who advocates the eco-friendly handling of water as early as the plant planning and construction permit phases.
Operational and sanitary waste water from the Chemical Industrial Park Knapsack and the adjacent companies is treated mechanically, chemically and biologically in the three-phase treatment facilities. Additional purification steps such as denitrification, phosphate precipitation and oxygenation as well as regular sampling and analysis by our own independent analysts and experts from the authorities ensure good water quality – and a responsible approach to our environment. Finally, the treated water flows via the nearby Duffesbach stream as well as a canal into the Rhine.
The waste water register constantly records the origin, type, amount and composition of the waste water. In the event of large amounts of precipitation, waste water displaying noticeably negative measurement results, production disruptions in the plants or a build-up of quench water, up to 30,000 cubic meters of contaminated water can be retained. This water is then disposed of in cooperation with the supervisory authorities.
