Not always, but in most cases yes . Factories usually produce several waste streams. Some of these streams can be reduced in flow and pollutant loading by introducing small changes in the production process. These changes require investments, but their benefits are usually greater than the required investments. A Waste Minimization Study is performed by experts in production process, waste sources, and waste recycling and recovery.
Several alternatives exist for effluent treatment.
There may be several alternatives for the disposal of the treated effluents, each one with different requirements of effluent treatment. Discharge to a stream or lake. Infiltration in the aquifer. Discharge to the municipal sewage network. A Feasibility Study for Effluent Treatment and Disposal is performed by experts on environmental conceptual engineering and effluent treatment process design.
