The horizontal flow filtration process was considered for treatment of wastewater. Whole filtering system contains three to four layers where sand layer acts as the main filtering media. Besides, various sizes of coarse aggregates which works as filter media and base materials. The thickness of sand layer was used 600mm while other coarse aggregate layers were about 150mm. There were three different sizes coarse aggregate. Top most layer contained the coarse aggregate of size varying from 3mm to 6mm. The intermediate layer contained the coarse aggregate of size varying from 20mm to 40mm and the last layer contained the large coarse aggregate of size varying from 40mm to 65mm.The main purpose of this study was to reduce the pollutant concentration.
