There are numerous nitrogen containing compounds found in wastewaters. TN (Total Nitrogen) represents all nitrogen present in the wastewater, including organic and inorganic forms such as ammonia, nitrate, and nitrite. Wastewater discharge limits and surcharges may apply based on one or more types of nitrogen.

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.
