Is Sludge Water Diluate Stream from Electrodialysis Suitable for Agricultural Purposes?

Sludge water, a product of drainage primary and activated sludge from the municipal wastewater treatment process, is rich innutrients, particularly nitrogen phosphorus. Nitrogen phosphorus are inorganic biogenic substances suitable for plantnutrition. water can be treated via electrodialysis. This process leads to two products, one diluate stream (solutionless concentrated than input, contains some nutrients) other concentrate (solution in which nutrients areconcentrated against input). There abundant research recovery stream, forexample form struvite used fertilizing. However, little attention has been paid huge volumes stream.The agriculture as irrigation, where bonus this partial fertilizingcapacity. way, irrigation fertilizing having subjected agrochemical analyses.An important condition use or absence heavy metals toxic substances.Still, if metals, they removed with relatively high success, example by precipitation.Using wastewaster agricultural purposes new options find secondary sources water.This theme highly topical it reduce consumption quality resources.
