Reinforced concrete, 2 rectangular basin, L=45 m, W=9 m, H=3.8 m, t=2.5 hĢ mobile bridge for sludge collection, 3 pumps and supplementary instrumentĪll mechanical instrument during design periodĪll mechanical instrument used in primary sedimentation This option cost about $ 4,757,200 and $ 950,213 when FeCl3 and PAFCl used as coagulant, respectively. Versus the cheapest option related to separate primary sedimentation, coagulation & flocculation in WTP. Cost estimation showed that contrary to expectations, the recirculation of settled SFBW to WTP entrance is more expensive than other method and it costs about $ 37,814,817.6. ![]() Coagulation conducted by PAFCl and FeCl 3 as pre polymerized and traditional coagulants. ![]() ![]() This article reports the cost estimation for treating produced spent filter backwash water (SFBW) during water treatment in Isfahan- Iran by various methods including primary sedimentation, coagulation & flocculation, second clarification, ultra filtration (UF) and recirculation of settled SFBW to water treatment plant (WTP) entrance. The dataset presented in this article are related to the research article entitled “Hybrid coagulation-UF processes for spent filter backwash water treatment: a comparison studies for PAFCl and FeCl 3 as a pre-treatment” (Ebrahimi et al., 2017).
