Decreasing of Multiple Clean Water Parameters in River Water Treatment

Abstract

The Characters of river water Surabaya, East Java, Indonesia at the time and specific location of Fe content up to 39.28 ppm, turbidity reach 345 NTU, DO 4.55-12.42 ppm, BOD is up to 12.48, COD 20-260 ppm TSS reach 2116.7 mg/l, detergent: 0.346 mg/l, bacteria E. Coli there were 50,000 MPN/100 ml, while samples of Bengawan Solo’s river, Central Java, Indonesia Boron exposure to 0.57 ppm, Cadmium 0.10 ppm, and Lead 0.442 ppm. That Parameters are not safe enough for quality standard of river water, especially as a clean water criteria. The decreasing of multiple parameters that refer to clean water criteria which can be done with a series of Coagulant Aid treatment, Silica Sand, Ferrolite, Manganese Greensand, and synthetic resins (cation anion) are performed in bath reactor .The research purposes is: decreasing of multiple clean water parameters in river water treatment using Coagulant Aid treatment, Silica Sand, Ferrolite, Manganese Greensand, and synthetic resins (cation anion)

Findings; In the river water treatment, parameters; Turbidity, Color, Iron, Total Hardness, Zinc, Organic Matter, Detergent, Total coliforms can be derived using Coagulant Aid treatment, Silica Sand, Ferrolite, Manganese Greensand, and synthetic resins (cation anion)
