Treatment of Wastewaters from Livestock Farms.

Raw wastewater from livestock farms is a mixture of faeces, urine, bedding materials, and water from washing and cannot be distributed on agricultural land in this state, and not discharged in natural emissions. That is why it is necessary to purify them, in order to retain and neutralize the harmful substances present in these wastewaters from animal farms, which are not accepted in the aquatic environment where the treated water is discharged and which allow the physical-chemical properties of the water to be restored before use. The paper analyses the importance of wastewater treatment from livestock farms, respectively the need to build efficient treatment plants. The possibility of using the advanced hydroinformatic tool WEST, developed by DHI Holland, is presented for the design, exploitation and optimization of such a treatment plant. [ABSTRACT FROM AUTHOR]
