Various physical and chemical methods are available to remove the nitrate from groundwater these are effective in removal but expensive in operation. Prevailing process, conditional influence and various approaches play important role in nitrate remediation. In present day situation, nitrate removal is important aspects of water treatment process. How much nitrate is allowed in drinking waterNitrate contamination has gain significant research interest, since presence of nitrate in large quantity in drinking water, often causes health disorders. Nitrate contamination of drinking water usually results from runoff of agricultural fertilizers or from human or animal wastes, such as livestock feedlots or faulty septic systems. Nitrate in Public Drinking Water Nitrate (NO 3) is an inorganic chemical composed of nitrogen and oxygen.From the experiment, it is found that, low cost bench scale treatment method was effective in nitrate removal as material used were cost effective and locally available. Adsorption method is extremely useful in nitrate removal for different dosages such as: 5 g/L, 7.5 g/L, 10 g/L, since it retains nitrogen within the root zone. In the present study, a treatment system was developed for community level comprising of anoxic batch reactor filtration unit and a chlorination unit.
The corrosion processes that could occur due to a. These.Cooling water treatment and analysing Background Correct cooling water treatment and follow-up of the cooling water condition are of utmost importance for keeping the cooling water systems of the engines in good condition. Hence it can be recommended compared to other methods.There are, however, several methods that can be used to reduce nitrate concentrations in potable water supplies with varying degrees of efficiency.
