Biogas production in water treatment plant - supporting the Lviv City programme

The need to implement the project, its concept and nature stem directly from the experience and knowledge of the partner team, taking into account the needs of the Lviv Oblast as determined through a project called “Lviv Oblast as a Region of Modern Management in Municipal Utilities”, which was implemented in 2012-2013. The diagnostic and conceptual nature of the project enabled an in-depth analysis of the region’s needs. The Lviv Municipal Council is currently working to enable implementation of a programme involving the production of biogas from sediments and leachates found at the municipal sewage treatment plant. The launch of the programme is planned within four years: the technology for the project has been selected, and the European Bank for Reconstruction and Development has decided to allocate funds for its implementation.

The main problem has been the lack of funds for conducting relevant tests and trials. In order to address this problem, the current project provides the needed support for the preparation, planning and implementation of the sediment and leachate laboratory tests. The project will deliver early results of the analysis in a relatively short period of time, integrate the entities responsible for the implementation of the Lviv Municipal Council’s plans, and provide know-how and Polish experience before key decisions are made. By using appropriate technologies and measures, Lviv is likely to become Ukraine’s national pioneer in terms of sediment and leachate management, as well as biogas production by a municipal utility.

In addition, the project is consistent with Ukraine’s policy of rapprochement with the EU. In order for Ukraine to fulfil the requirements of European directives, which regulate, among other things, the recycling of waste (including sediments and leachates) and reduction of the amount of stored biodegradable waste in the overall amount of waste, the country needs trained, knowledgeable and motivated staff, as well as a positive model for the implementation of such projects in Ukraine.

Biogas production in water treatment plant - supporting the Lviv City programme

The objective of the project is to support the Lviv Municipal Council’s planned programme for the extraction of biogas from the municipal sewage treatment plant. This includes an investigative phase, which is intended to determine the production capacity of the biogas combined with the sharing of Polish experience in municipal utility management with Ukrainian local governments.

The project tasks include a comprehensive examination of the Lviv Sewage Treatment Plant leachates and sediments, particularly from the standpoint of their biogas production potential, and installation of a biogas production plant (up to around 1 square metre). The objective here is to provide detailed analytical data of crucial importance to the municipal biogas production programme.

The project will also include an analysis of the current condition of the Bug River in the context of protecting its watershed, in international terms. Pollution of the river occurring outside Poland is currently a serious problem.

The project will be completed with study tours for representatives of Ukrainian local government to facilitate the transfer of know-how and the presentation of new technologies, as well as Polish best practices and success stories. Two such study tours around Poland will be organised for a total of 35 people, with the aim of presenting the achievements of municipalities located along the Bug River in eastern Poland, as well as the latest technologies that were demonstrated at the POLEKO 2015 trade fair. A summary review of the entire project will be provided at a conference in Lviv that will also include a module involving expert consultations.

Biogas production in water treatment plant - supporting the Lviv City programme

1.           A paper entitled “Protecting the waters of the Bug River: Situation analysis” was prepared by a joint team of Polish and Ukrainian experts. The study contains a precise description of the Bug River and an analysis of environmental protection measures being taken, along with a description of the sewage treatment plants operating in its watershed, as well as the relevant institutions and the programmes they are implementing (including those with international ramifications). The study also incorporates the results of water quality monitoring, including those obtained through research carried out as part of the project. The material was prepared in both Polish and Ukrainian, and is also available through the project website. An electronic version was delivered to the project partners for further distribution among all interested parties.

2.           A study entitled “Production of biogas in a sewage treatment plant: An analysis” was prepared by a joint team of Polish and Ukrainian experts. It includes descriptions of the Lviv Sewage Treatment Plant, the Lviv biogas production programme, the experience of other countries, the approximate biogas resources available in Lviv, and the possibilities of using the research installation acquired as part of the project. The study also incorporates the results of water quality monitoring, including those obtained through research carried out as part of the project. The material was prepared in both Polish and Ukrainian, and is also available through the project website. An electronic version was delivered to the project partners for further distribution among all interested parties.

3.           The launch of a research biogas production line: the project provided a grant that covered the entire cost of the installation of an industrial vacuum-scrubber dryer, model РВ0,8-1,6ВК-01, including its purchase, assembly and commissioning. This represents a physical model of a fermentation chamber. Its key advantage is its solid manufacturing: its impermeability, heating uniformity and the homogeneity of the mixture (through the use of a scraping mixer). In addition, it can mount all the necessary control and measurement instrumentation, and all the necessary technological operations can be easily performed. The model is recognised for its reliability and ease of operation (including maintenance). In addition to its ability to produce biogas for testing, the device can also be used to dry sludge, which increases the range of possible tests. Moreover, it can carry out testing at a wide range of temperatures, pressure and mixing levels, which greatly increases the scope of possible tests.

4.           Eighteen representatives of local governments and the waste management sector learned about the latest technologies and equipment by taking part in the POLEKO 2015 trade fair. The results of an evaluation questionnaire and the feedback obtained by FARR administration staff testify to the fact that the project’s goals were fully achieved. The 18-person Ukrainian delegation primarily included members of the administrative and research staff of the Lviv Municipal Council and its subsidiary entities (waterworks, laboratory). Presentations about modern technologies, logistics and technical solutions, and the practical experience of Polish municipalities and their utility companies provided participants with valuable information. A visit to the Aquanet Central Sewage Treatment Plant made a particularly positive impression on the participants, who assessed their study tour as useful and interesting.

5.           Fifty representatives of local governments and the waste management sector learned about methods for rolling out sludge and leachate management programmes by taking part in a conference organised in Lviv in December 2015. The results of a survey and the feedback provided to the project partners after the conference indicated a significant increase in knowledge about possibilities for recycling sewage sludge, biogas production at a sewage treatment plant, and the resources available to the Municipality of Lviv in this regard. The materials and conclusions presented by Polish and Ukrainian experts allowed the participants to learn more about the problem. In addition, the way in which the conference was conducted allowed unconstrained discussions among the participants and easy access to the experts, which increased the audience’s engagement and facilitated in-depth exploration of the key issues.
