Urban Waste Water

Tests for the industrial water supply of a community center by grey water use according to catalytic UV oxidation

The transmission values of grey water (shower water and rain water) with a wavelength of 254 nm were between 30 and 40 %. On the basis of these values and a transmission/output and effectiveness diagram a UV reactor for the disinfection of the grey water with 125 W radiation performance and 200-300 l/h water quantity throughput was applied. The analyses showed that the UV prepared industrial water is applicable for the toilet flushing (detailed information in German).
