Within the framework of the project, the execution of the last contract has started: the specialists of SIA “BALT SPEKTRS L” carry out the installation of 4 new air blowers in the sewage treatment facilities.
Air blowers are an integral part of the biological wastewater treatment process, which at the same time is the most energy-consuming equipment (the basis of the technological process is the use of special bacteria, which need oxygen for maximum decomposition of pollutants and life support, which must be continuously supplied to the air blowers). Until now, air blowers used in sewage treatment plants in Daugavpils are physically outdated and energy-intensive, which increases the costs of the company and, accordingly, the tariffs of the provided services in the conditions of the increase in electricity prices.
Due to the complexity of the work and its importance for the efficiency of the biological treatment of wastewater, the official representatives of the equipment manufacturer are also invited to check and start up the installed air blowers. In order to achieve a stable and continuous flow of oxygen and the necessary wastewater treatment parameters during this period, 4 air blowers are replaced gradually: only after the successful start-up of the first two air blowers, an invitation will be sent to the specialists of SIA “BALT SPEKTRS L” to perform the installation work of the next two air blowers.
The purpose of the project – promote the improvement of the energy efficiency of the technological processes of the municipal capital company SIA “Daugavpils ūdas” by reducing the consumption of primary energy, using energy produced for self-consumption in solar power plants and energy-saving equipment.
In order to achieve the goal of the project, 4 water pumps in the “Vingri 1” reservoir and 2 return sludge pumps in the sewage treatment facilities have already been replaced, as well as the installation of solar panels has been completed.
construction of systems in the water de-ironing station “Ziemeļi” (power 90 kW) and in the water pumping station “Vingri 2” (power 70 kW). After all the necessary inspections, the process of putting the construction objects into operation will be started.
As a result of the implementation of all project activities, primary energy consumption will be reduced by 524.9 MWh per year, which will reduce the amount of greenhouse gas emissions by 57.214 t per year, the additional power produced from renewable energy resources will amount to 0.160 MW.
The total cost of the project is EUR 765,574.21 excluding VAT, incl. eligible costs EUR 765,574.21 (of which ERDF co-financing 85% – EUR 650,738.05 and Daugavpils municipality’s investment in the share capital of SIA “Daugavpils water” 15% – EUR 114,836.16).
Project implementation time – from May 23, 2022 to October 22, 2023.
