Evaluating the efficiency of a baffled-filter system with sponge media on removal of turbidity, microbial agents, and total organic carbon from water
Background and Objective: Access to safe water is critical for protecting human health. Turbidity is one of the main physical parameters that affect the quality of water from both health and aesthetical points of view. Therefore, waters should be treated based on the standards set for turbidity before consumption. This study was performed to determine the performance of a bench-scale baffled fi...
متن کاملمقایسه کارایی صافی یک لایه با بستر ماسه و صافی دو لایه با بسترهای لیکا و آنتراسیت در حذف مواد آلی و کدورت
Backgrounds and Objectives: Improvement of water quality standards and inability of mono layer filters in producing such quality caused researchers attended to multi layer filters. Due to specific characteristics of anthracite and leca can improve removal of organic materials and Surface over flow rate. The aim of this research was evaluation performance of dual media filters (anthracite/leca) ...
متن کاملInfluence of chlorothalonil on the removal of organic matter in horizontal subsurface flow constructed wetlands.
This study investigates the effects of chlorothalonil (CLT) on chemical oxygen demand (COD) and dissolved organic carbon (DOC) in pilot-scale horizontal subsurface flow constructed wetlands (HSSFCW) planted with Phragmites australis. Physicochemical parameters of influent and effluent water samples, microbial population counting methods and statistical analysis were used to evaluate the influen...
متن کاملevaluation of horizontal - flow roughing filteration performance in turbidity removal
slow sand filtration (s.s.f) is a main process in the water treatment technology and generally considered as most appropriate for application in rural and small urban areas in developing countries. however, performance of the s.s.f is very sensitive to high turbidity levels. therefore, pretreatment is necessary for such waters. horizontal - flow roughing filtration (hfrf) and direct horizontal ...
