Non-point pollution source refers to pollutants distributed over unspecified points instead of a specific point (specific pollution source) and discharged through transportation and drainage systems due to rainfall. >It refers to pollutants discharged together with rainfall effluent usually during rainfall, such as fertilizer and pesticide sprayed on farmland, deposition of air pollutants, sedimentary pollutants on ground surface and pollutants within combined sewer overflows and places that generate such non-point pollutants are called non-point pollution source.
Automatic non-point pollution reduction device
Initial stormwater with high pollution level during rainfall flows into the primary settling tank for earth and sand to be deposited and after it is transferred to the treatment tank by automatic flow regulator, fine Suspended Solids (SS) are filtered by multi-filters while Dissolved Solids (DS) are adsorbed for removal and after rainfall ends, it is automatically discharged and cleaned
Fast and convenient installation so interference with other processes is minimized
Non-powered filter system of pre-treatment process
Various medium can be selected depending on the characteristics of inflow water quality
