What is treatment for water containing turbidity and iron?
Water containing iron will be turbid and brownish. On standing, the turbidity settleswithin 2 to 12 hrs depending on the form in which iron is present (inorganic or organic iron). The water after settling can be filtered and directly used. Addition of bleaching powder and alum (at a dosage level of 20 g and 30 g respectively per 1000 liters) can quicken the settling of iron and the water can become clear within 1 to 2 hrs.
