The purity of water significantly determines the quality of our environment. Waste water treatment plant operators are faced with an enormous responsibility: their plants must meet ecological and economical requirements. Only with maximum performance waste water treatment plants are capable to operate economically. The increased stringency of laws in many countries confronts operators with new challenges. As a specialist for waste water treatment, Kurita has the right answers to questions arising in connection with the operation of waste water treatment plants. Our field engineers conduct surveys with the responsible employees on site and take water samples for analyses in our laboratories. On the basis of this information we develop our solutions. Before implementing the corresponding applications at your plant, we test simulated operations in the laboratory. Online analyses during operation safeguard the applications and allow short-term corrections, if required, for example due to changes in operating conditions.
