Abstract :

An integrated filtration system has been developed for drinking and washing purposes. This is a bench scale unit made of locally available low-cost materials. The unit can remove iron and bacteria, and produce household water maintaining the accepted standard. The operation and maintenance of the plant is simple and could be done by unskilled labor. Based on the experimental results, techno-economical evaluation has also been done for a large-scale plant. The academic building ‘B’ of SUST is selected as a model object for water supply and the technical target is to reduce iron to standard level. Cost calculation is based on the analysis of its several components such as construction materials with their respective quantities, mechanical equipment, energy consumption, chemical consumption, and operational and maintenance expenses. The result can be extended for quick financial evaluation of the similar systems as well as for the general decision making plan.
