Filtration process
1.This video will give you details about the filtration process of water purification.
2.Filtration process is carried to remove the bacteria, suspended and colloidal materials, color, odor, iron and manganese and also useful in making water sparkling.
3.Filtration process consists of passing raw water through filter media, filter media consist of sand and gravel layer filtration process removes about 98 to 99 % of bacterial impurities.
4. When loss of head increases and removes blockages from the filter bed process is carried out.
