Ammoniacal nitrogen - Hyperleap

Ammoniacal nitrogen, (NH 3 -N) is a measure commonly used for testing the quantity of ammonium ions, derived naturally from ,ammonia,, and returned to ,ammonia, via organic processes, in water or waste liquids. This is because leachates contain very high ,ammoniacal nitrogen, concentrations, are usually very ,acidic,, are often anoxic and, if received in large volumes relative to the incoming sewage ...

Therefore, most dyei ng water is ,alkaline, and the first process is to adjust the pH value of the textile dyeing ,wastewater,. The total ,nitrogen, and ,ammonia nitrogen, come from dyes and raw materials, which is not very high, about 10 mg/L. But the urea is needed while using batik techniques. Its total ,nitrogen, is 300 mg/L, which is hard to treat.

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 …
