Pilot device for waste water treatment


Tallinn University of Technology TUT is working to find feasible technical solutions for removing harmful substances and phosphorus from waste water. TUT has built a pilot treatment device, which was in test use at the Tartu waste water treatment plant WWTP in the spring and summer 2018. Currently, the device is tested at Kohtla-Järve WWTP in eastern Estonia. Tallin University of Technology TUT is aiming to find techniques that can be cost-efficiently applied at municipal WWTPs to enhance the cleaning process. The structure of the pilot device allows testing different filtering materials, coagulant doses and chemicals. Cost-efficiency of these alternate technologies is evaluated by comparing use of energy, and treatment chemicals to the treatment results.
