Construction Panevėžys sludge treatment plants

Category
Water and waste water treatment
Builder
UAB “Aukštaitijos vandenys” (Ltd.)
Project location
Panevėžys, Ramygala, Krekenava (Lithuania)
Project timeframe
Contract was signed in 29-07-2010 finished in 23-12-2015

Sewage slut drying facility (amount of dried sludge is 3524 tons/year (2016)) was constructed in Panevėžys, and sludge, compacted in Ramygala and Krekenava wastewater treatment facilities, is transported for digestion to Panevėžys wastewater treatment plant.

 

 

The project helped to solve the common problem of wastewater sludge treatment in Panevėžys region. While expanding  the wastewater collection and treatment infrastructure in Panevėžys region, the amount of sludge, generating during wastewater treatment, is growing accordingly, therefore, there was a need install more modern, efficient and environmentally friendly technologies of sludge management, allowing to reduce the amount of sludge and to use the treated sludge as a renewable energy source.

The sludge treatment facilities, constructed during the project in the existing Panevėzys wastewater treatment plant, created the necessary sewage sludge management capacity in Panevėzys, which will treat the sewage sludge resulting from Panevėzys region, Kupiškis, Ramygala and Krekenava sewage treatment plants, and will obtain the product that would be utilized, stored and processed in the most economical way. The current capacity of Panevezys wastewater treatment plant is 36000.00 m³ of wastewater per day. Currently, approximately 28,000.00 m³ of wastewater is treated per day, resulting in 100 tons of sludge per day. Construction of sludge treatment facilities decreased the volume of the resulting sludge by approximately 3-4 times, and the pellets can be used as a renewable energy source. This project reduced the negative effects of sludge pollution on surface and ground water, soil, and residents.

Upon implementing this project, the following problems were solved in Panevėžys region: the amount of sludge, sludge odor, sludge stabilization, greenhouse gas emissions. Upon installation of new sludge treatment facilities, sewage sludge is digested and dried, resulting in increase of the treated sludge utilization and reduced amount of sludge on sites, prevention of soil/ground pollution.

Implementation of this project contributes to the solutions of problems, according to the Cohesion Action Plan for the period 2007-2013, where it is specified that upon implementation of the programme, approximately 80% of Lithuanian sludge will be treated by using modern technologies.

Effective scheme of the investment project management and supervision of project implementation is developed in the project area, which will allow effective and fast implementation of the next projects.
