Use of Micro-Irrigation to Irrigate with Purified Waste Water

Abstract

Experiences gained by use of purified wastewater for microirrigation are presented in this paper. Microirrigation with wastewater is distinguished by favourable cleaning effect, high degree of use of water and corresponding protection of environment. Within the framework of our research inquiries we aimed at the device for finalisation of cleaning wastewater by sieve filters with floating refills made from foamed polystyrene and polyurethane. We recommended simple device for disinfection of water by UV rays, testing of suitable types of discharge equipment and worked out programme methods for proposing irrigation lines for point irrigation, drip irrigation and microsprays. In the process of finding out cleaning effect of soil in micro-irrigation we found out cleaning effects exceeding values obtained with classical irrigation of medium spray and irrigation by flooding and outlets.
