01. Research on ammonium removal from household well water using coconut fibre

Thủy Trịnh Thị , Mai Vũ Thị


Well water has a high content of ammonium which is easily converted into a more toxic form for affecting human health such as nitrite. It is difficult to remove ammonia from well water. In Hanoi, well water from some areas has much highter content of ammonium than allowed national standards. Therefore, the research on the removal of ammonium in household well water always receive the attention of society and scientists. This study assessed the ability to treat ammonium in well water in Duc Thuong commune, Hoai Duc district, Hanoi using coconut fiber combined with some other common filtration materials. The results show that, although the content of ammonium in well water is very high (exceeding the standard QCVN 09:2015/BTNMT 32 - 35 times), the filter with coconut fiber layer has higher ability to remove ammonium than the traditional filter using only sand and gravel. The ammonium removal efficiency of the coconut fiber filter is up to 70%, much higher than that of the traditional filtration tank (only 15% ammonia removal).
