REMOVAL OF AMMONIA EFFLUENT FROM ABR BYCONSTRUCTED WETLANDSBOWO DJOKO MARSONO AND BIEBY VOIJANAbstract Communal domestic wastewater treatment plant has been widely built in the area in Indonesia. The government through the Ministry of Public Works and Public Housing with several programs has built a Communal IPAL in almost all districts in Indonesia. Domestic wastewater treatment generally uses ABR (Anaerobic Baffle Reactor) technology. Domestic wastewater treatment with ABR can reduce organic carbon and total suspended solid concentration but less effective in reducing ammonia. ABR has a bod seed and efficiency of BOD 80%, COD 90%, TSS 70% and Ammonia 20%. The presence of Ammonia in the receiving water body will lead to decreasing oxygen levels and eutrophication. Applied phytotechnology can be a solution to overcome effluent levels in ABR as long as there is sufficient land. Research has been conducted that the efficiency of ammonia reduction in Wetland reached 76%. |
