Description
Summary:The paper proposes a new water quality criterion for the evaluation of the water potential to clog screen filters which protect drip irrigation systems. This additional parameter is required by the increasing use of reclaimed wastewater for drip irrigation. A filtrability test which simulates actual clogging processes is used to analyze reservoirs receiving different portions of reclaimed wastewater (0 to 100 %) and the use of fish to reduce the particle content of water. The study demonstrates the suitability of the filtrability test to measure and analyze the clogging capacity of irrigation water, and the possibility to reduce clogging problems by proper reservoir management.
