Using Fly Ash and Laterite as a Filtering Media

The present study reports the comparative study of soil-based constructed soil filter system monitored for about 2 months for removal of turbidity of turbid water in which fly ash and laterite is used as filtering media. The samples passed through this arrangement, includes water collected from Wainganga (Wadsa), Gaurav paper mill Bramhapuri, Bhuti-nala (Bramhapuri), Ballarshah paper mill and Thermal power plant (Chandrapur). The result indicates removal of turbidity from these samples ranging from 3 NTU to 21NTU. Various other tests were also performed to check whether the water is potable or not viz., temperature, pH, dissolved solid, hardness of water, BOD & COD. The water passed through this arrangement reduces pH value from 0.1 to 1.3, dissolved solids from l6Oppm to 1528ppm, hardness reduces from 220 to 560, BOD r educes from 8ppm to 67ppm and COD reduces from 23ppm to 90ppm.
