PARTICLE SIZE ANALYSIS OF SUSPENSIONS IN REMOVING OF ORGANIC MATTER AND PHOSPHORUS FROM WASTEWATER AND SURFACE WATER
Abstract
In this paper the particle size of suspended solids in the removing of organic matter and phosphorus compounds from lake water and wastewater treated in the Ecological Treatment Systems (ETS) was analyzed. The invesigated materials were taken from two ETS located in Pomerania Region/Poland. Object in Swarzewo is 3rd stage of biological treatment of municipal wastewater, while object in Kartuzy has task to remove a phosphorus from lake water. To deepen the knowledge about migration of pollutants in water and wastewater their particle size analysis based on the laser diffraction method were carried out. Speciation of phosphorus and organic matter expressed in COD was carried out for the purpose of determination of the participation and type of dissolved substances as well as suspended matter. The granulometric analysis showed that from wastewater and lake water treated in ETS the suspension above size 100 μm is efficiently removed. On the basis of the obtained results it was proved that ETS efficiently remove particulate fractions of phosphorus and organic matter. In wastewater and surface water inflowed to analyzed facilities 30-45% of organic matter and 55-80% of phosphorus was attributed to suspended solids. In the effluent a part of pollutants in suspended fraction decreased and it were 15% for COD and 35% for phosphorus in wastewater and 24% for COD and 50% for phosphorus in lake water.
