Investment into installing new equipment in Daugavpils WWTP, which allows organizing maintenance works without harm to technological process and keeps separate electricity records by main consumer groups.
Project activities related to Grevesmühlen WWTP have been carried out by two project partners: with the investment hosted by the plant, a decision making tool for optimized process operation and mass flow management has been prepared by the aqua & waste International GmbH company. To calibrate the developed tool, Grevesmühlen WWTP launched investigation of the process under varying conditions, focusing particularly on thermal hydrolysis.
Tartu Waterworks Company is the second biggest municipal wastewater treatment plant in Estonia and one of the many WWTPs in the Baltic Sea Region where anaerobic digestion of sludge is applied. There, a full-scale deammonification technology was developed and installed with regard to demonstrate in-situ start-up of deammonification without external seed.
Within the framework of IWAMA project Jurmala WWTP is piloting a drying and incineration unit (hereafter, unit). The unit is designed to reduce the amount of surplus sludge from the wastewater treatment process using vapor of thermal decomposition of volatile products and non-condensable gases as fuel. It is integrated into the existing technological chain of WWTP.
A pilot investment was done in Türi and Oisu wastewater treatment plants (Estonia) in order to show a good example of efficient sludge treatment for small-scale plants by applying the technology of sludge humification beds.

Investment in Gdansk aims to develop and test energy efficient and cost-effective concept uniting processes that require low energy consumption treatment. The investment includes a combined anammox-constructed wetland pilot plant and additional energy meters installed at the WWTP. The examined technology focuses on minimizing energy consumption for the removal of organics and nutrients while maximizing recovery of organic matter from wastewater to produce renewable energy.
The pilot investment involves installing the online nitrogen measurement devices to be used for monitoring nitrogen concentration in the aeration tanks, as well as installing the mass airflow sensors to measure air flow to the aeration tanks to allow advanced process automatization and programming for energy optimization of the blowers.
