The relations of flow-cost for domestic wastewater treatment plants

In this study, flow rate-cost relations of the different wastewater treatmentplant were investigated which used for to be treat domestic wastewater usingcomputer software. The cost was investigated for domestic wastewater treatmentplant alternatives at the different level of flow-rate quantity. Thus, the cost oftreatment plants are drawn via to flow rate-cost diagrams showing the relationshipsbetween flow rate-construction cost, flow rate-operation and maintenance costs,flow rate-land cost and flow rate- cost of treating 1 m3 of wastewater. However,considering the discharge standards of water pollution control regulation wastewatertreatment plant units were designed and this treatment plants including separate unitswere compared with each others.Key Words: Domestic Wastewater, Treatment, Investment and Operation Costs,Flow-Cost RelationshipsII
