background: as fluoride concentration in drinking water is one of the effective parameters in human health, finding the ways to remove excess amount of fluoride is very important in water supply projects. this study aimed to evaluate mendon bauxite mine in the removal of fluoride from drinking water. methods: this experimental study was conducted from may to october 2013 on synthetic and actual...
Background & Aims of the Study: Coagulation is an essential process for the removal of fine particulate matter in water treatment. Polyaluminium ferric chloride (PAFC) is a composite inorganic polymer of Aluminium and ferric salt. This study was conducted to find out the optimum coagulation conditions for the removal of turbidity, color and organic matter (UV absorbance) in low to mediu...
Background and purpose: Imidacloprid (IM) is a systemic insecticide that is widely used to control a large number of pests in agriculture. It has toxic effects, therefore, it should be removed using appropriate methods. The aim of this study was to evaluate the efficiency of electrochemical degradation process to remove IM from aqueous solutions. Materials and methods: In this experiment, a gl...
conclusions it was shown that the removal efficiency of nitrate was directly proportional to the amount of chaff, temperature, and contact time but inversely to the ph. this study showed that nitrate removal by chaff is a promising technique. results the result of this study revealed that chaff as an absorbent could remove nitrate from solutions, and the efficiency of adsorption increased as co...
