NP unit for treating N (nitrogen) and P


In areas close to water, the cleaning efficiency is improved with the NP unit. The urine and flushing water are separated, they contain 90% of the households' nitrogen load and 60-80% of the phosphorus load. In the NP unit, this nutrient-rich but small amount of sewage is treated. The NP unit oxidizes nitrogen and doses RAKE chemical. Oxidized nitrogen (nitrate) is reduced and RAKE precipitates phosphorus in the sludge separator. The same sludge separator (septic precipitation tank) can also be used for pretreating of gray waters (the rest of the sewage).
