Treatment of ammonia-polluted groundwatter in North Bohemian brown coal mining region - feasibility study
Original language description
A feasibility study was completed to assess the applicability of reverse osmosis technology at the site, where a brown coal processing plant released 4000 ton of ammonia into the subsurface during 20 years. The present groundwater ammonia concentration (approx. 100 ppm) was required to be reduced to 0.5 ppm to satisfy the Czech groundwater remediation directives. The reverse osmosis principle was examined within this study with the aim to confirm its capacity to reach the ammonia remediation limit as well as to provide cost estimation. The technological process was simulated by means of pilot-scale installation using samples of contaminated groundwater. Reverse osmosis clearly demonstrated its capacity to clean up the ammonia polluted groundwater to the limit demanded.
