Urine Separation

Removal of Micro-Pollutants
Reuse as Fertilizer
Prevention of Eutrophication

Urine (yellow water) can be separately collected by use of separation toilets and waterless urinals. Only about 1.5 litres of urine are produced per person every day.

As Urine contains most of the nutrients, but little organic carbon. Urine contains few pathogens, but most of the so-called micro-pollutants which are composed of excreted endocrinic substances, such as hormones, and remaining pharmaceuticals, such as antibiotics.

Urine has great value as fertilizer or as raw material for the cosmetic industry. Due to self-inhibition of its degradation by rising pH-value, undiluted urine can be stored long-term without causing odour nuisance.

Where urine is separated, it is easier and less costly to treat the remaining wastewater. Expensive treatment for the removal of the nutrients nitrogen and phosphorus is no longer needed.

Inexpensive MeChem Solutions (see above) for cost-efficient removal of solids and organic pollution become even more efficient when they are combined with urine separation at the source. Eutrophication of receiving water bodies is thus avoided.

As soon as removal and destruction of micro-pollutants will be required, urine separation will become a necessity. It will be far easier to remove micro-pollutants from a small volume of urine than from the large volume of diluted wastewater.

Reuse of urine as liquid fertilizer; On-site wastewater treatment and effluent reuse as service water and for irrigation
