„Decentralised water treatment how does the water framework directive influence it?” Stockholm, 21st September 2011 Decentralised wastewater treatment in Poland on example of selected technology highlight Dr. Włodzimierz A. Sokół National Contact Point for Eco-efficient Technologies and Management Systems Decentralised wastewater treatment, Stockholm 21.09.2011 in Central Mining Institute, Katowice - Poland

Wastewater treatment in Poland • By the end of 2015 Poland has to achieve EU standards of cleaned wastewater and achieve 75% of reduction of whole nitrogen and phosphor in municipal wastewater by implementation of the National programme on wastewater treatment and Baltic action plan on reduction eutrophication of Baltic Sea Depends on regional and local conditions • According to statistical data for 2008, only 63.1% of the population is serviced by wastewater treatment plants • About 98,67% of Polish cities were served by centralised wastewater treatment plants and 86,9% of the city populations and 25,7% of rural population Decentralised wastewater treatment, Stockholm 21.09.2011
Wastewater treatment in Poland • Poland is very pour in drinking water resources so saving water by reuse of grey water and use of rainwater have to be priority not only for decentralised but for centralised wastewater systems as well • Significance of decentralised wastewater treatment was noticed on national level an the National Fund for Environmental Protection and Water Management foreseen 300 milion PLN for building 11.000 household wastewater treatment plants and 21.000 connections to centralised systems Decentralised wastewater treatment, Stockholm 21.09.2011
Wastewater treatment in Poland • The worst situation is in the rural, where the length of wastewater network is fivefold shorter then water network and decentralized wastewater treatment is sometimes only one solution or cheapest option with comparison to centralised system • A lot of decentralised wastewater treatment installations are used in Poland in rural areas and in areas where no access to centralised wastewater treatment based on national on foreign technologies but very often wastewater remains untreated or is cleaned insufficiently • Innovative ENKOSYSTEM is proposed by ENKO company as the offer for decentralised wastewater treatment Decentralised wastewater treatment, Stockholm 21.09.2011
1. Purpose Sewage treatment in single household and small villages which are difficult to cover by central wastewater system in view of: • big distraction • area formation • area secure Decentralised wastewater treatment, Stockholm 21.09.2011
2. ENKOSYSTEM - construction 2 vessels equipped with technological system covering mechanical, chemical and biological treatment processes together with automatic control Decentralised wastewater treatment, Stockholm 21.09.2011
3. Multifunctional vessel – located under ground, divided into 3 zones • Gravitational sewage collection and sepa- ration constant factors from organic liquid • Plastic filter with formed biological systems which launch demineralization reaction, nitrification reaction and dephosphatation reaction of sewage. • Central zone with installed dozing pump. Decentralised wastewater treatment, Stockholm 21.09.2011
4. Biological vessel– presents system of spicy-floral sewage cleaning system and absorption of left mineral compounds • External zone – sewage aeration by system of microbes settled on plants roots and absorption of arisen mineral compounds by roots system • Internal zone – further processing by microbes seated in keramzyt pores and natural filtration left suspended matter through keramzyt layer. • Gravitational cleaned water outlet Decentralised wastewater treatment, Stockholm 21.09.2011
5. ENKOSYSTEM – benefits • mall construction footprint required • Very high efficiency: up to 1,5 m3/day • Valuable final product – odor-free and without sediment • Maintenance free process with automatic control • No chemicals required • Very high outside esthetic – plants decorativeness • Very low power consumption app. 1,7 kWh/day Decentralised wastewater treatment, Stockholm 21.09.2011
6. Possibilities of use cleaned water • Partly return to sewer system installation • Gardens watering • Cars washing Outlet of clean water Multifunction vessel aeration Biological vessel pump Decentralised wastewater treatment, Stockholm 21.09.2011
5. Achieved results Decentralised wastewater treatment, Stockholm 21.09.2011
6. Costs comparison: ENKOSYSTEM andexploi-tation of cesspit(4 people, 100 l /per person per day) Decentralised wastewater treatment, Stockholm 21.09.2011
