Ozone water treatment in small water purification plants in Poland - Mszana Dolna case study
Jan Pawełek , Tomasz Bergel
AbstractThe study analyzed possibilities of using ozone for water treatment in supply stations that provide water to small water supply systems. We analyzed a containerized water treatment plant (CWTP) in Mszana Dolna, located in Małopolska region, with a nominal production of 15 m3∙h-1. The plant uses a two step pressure filtration system with indirect water ozonation prior to active carbon filters. The treated water meets all the requirements set for drinking water. A cost analysis was also carried out to find out whether using this type of technology in small water supply stations in Poland is economically justified. The calculations were based on water production and its costs in 2017. The unit cost of water amounted to 0.59 and 0.77 EUR∙m3 for the variant taking into account a nominal water production and a hydraulic load of the station in 2017 that reached 58.7% f a nominal load.
