In order to treat coke-plant ,wastewater containing, high level of ,ammonia, (5,000 mg/L at pH 11), Lin et al. developed an effective method to remove the ,ammonia, by microwave radiation. To find an optimal operating condition, the experiments were conducted under different pH levels, radiation time, with and without aeration, and initial ,ammonia, concentration.

The Role of Nitrogen Fertilizer on Soil pH | Brookside Labs

When ammonia is added to the soil it reacts with water to form ammonium-N, which is an, alkaline, reaction that initially raises the pH of the soil. However, as ammonium-N undergoes nitrification acidity is produced. These two reactions (the, alkaline, reaction of ammonia and the acid reaction of ammonium-N) do not quite balance out, but come close.

In recent years, the excess discharge of ammonia nitrogen from wastewater into surface water has been regulated by more stringent standard. The air stripping method is successfully used to treatment of high-concentration ammonia nitrogen; however,, alkali, will be added to keep pH more than 10, which is costly and not environment-friendly operation.

The test for pH value of ,wastewater, is carried out to determine whether it- is ,acidic or alkaline, in nature. Fresh sewage is generally ,alkaline, in nature, (its pH value between 7.3 to 7.5). However, as the time passes, pH value tends to fall due to production of acids by bacterial action, and the sewage tends to become ,acidic,.
