Building iron removal model in Drinking water treatment

Abstract

     Topics have been designed and constructed the model of iron reduction in drinking water by method of raindrop combined with filtration through the layer of filter materials based on Vietnam Construction Standards TCXDVN 33: 2006 - Water supply - pipeline network and works, efficiency up to 93.4%. The operating model achieved high results with the initial water before treatment have high iron concentration in excess of the limit allowed was 3,8731mg/l, but after treatment the iron concentration reduced was 0.1895mg/l. The iron concentration after treatment within the rules allow QCVN 01: 2009/BYT - Regulation National technical standards for water quality and QCVN 02: 2009/BYT - National technical Regulation on drinking water quality.

    The research also found the optimal conditions in the process of reducing iron, evaluation, compare the treatment efficiency, as well as the cost of different materials and find the optimal adsorption material for the process is Filox. In addition, the model can be applied in practice. The model is invested quite cheap, with about 4,000,000 VND for technology investment, each household can successfully build models for effective treatment iron in drinking water with standards allowed for capacity of 1m³/day.
