Wastewater Treatment For Irrigation. For all applications in Water Treatment. As a by-product of conventional wastewater treatment sewage sludge is introduced as a potential agricultural resource in combination with wastewater irrigation. Unlike slow-rate systems overland-flow systems are designed to facilitate the runoff of wastewaters. In developing countries raw or partially treated wastewater is often used to irrigate crops especially in arid regions.
Direct use of treated wastewater is the use of treated wastewater where control exists over the conveyance of the wastewater from the point of discharge from a treatment works to a controlled area where it is used for irrigation. Unlike slow-rate systems overland-flow systems are designed to facilitate the runoff of wastewaters. The design of wastewater treatment plants has usually been based on the need to reduce organic and suspended solids loads to limit pollution of the environment. Nutrients in municipal wastewater and treated effluents are a particular advantage of these sources over conventional irrigation water sources and supplemental fertilizers are sometimes not necessary. The above requirements are equally applicable when the source of irrigation water is treated wastewater. Fluence is the world leader in decentralized treatment technologies.

Because the use of treated wastewater for irrigation was not included in mainstream planning in many countries treatment plants turn to be further away from agricultural lands. Free information - no commitment. Wastewater treatment processes achieving the recommended microbiological quality consistently as a result of their intrinsic design characteristics rather than by high standards operational control are to be preferred. Advice from veteran experts. For all applications in Water Treatment. Primary Treatment of Wastewater Primary treatment of wastewater is quite effective as it filters out almost 25-50 of biochemical oxygen demand BOD 5 more than 50 of Suspended Solids SS and 65 of the oil and grease.
