Efficiency of horizontal roughing filter in removing nitrate, phosphate and chemical oxygen demand from effluent of waste stabilization pond
Background: The effective size of the end grain of horizontal roughing filters (HRFs) is larger than 2 mm. This study aimed to examine the efficiency of HRFs in removing nitrate, phosphate, and chemical oxygen demand (COD) from effluent of a wastewater stabilization pond. Methods: This experimental study was conducted in 2013. The pilot project was transferred to the Karaj wastewater treatment ...
متن کاملNutrient Elimination from Effluent of Municipal Wastewater Treatment Plant Applying Horizontal Roughing Filter
High levels of turbidity and suspended solids are the major disadvantages of aerated lagoons. Aerated lagoon effluent filtration was investigated by Horizontal Roughing Filter (HRF). Removal efficiencies were determined by examining total phosphorus (TP) and total Kjeldahl Nitrogen (TKN) from HRF influent and effluent, simultaneously. HRF pilot system located on effluent pump station of Qom was...

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 ...
