Abstract
Sustainable development with environmental protection is one of the greatest challenges of the 21^st century. There is a growing consideration of the sustainable development and environmental management in new industrial cities. Investigational aspects were carried out in El Obour city as Egyptian new industrial city for estimating the current wastewater problems as well as applying mitigation actions. Industrial inventory was constructed for selected industrial sectors as food, chemical and textile sectors including water consumption, materials and energy resources. Wastewater samples from different factories and lifting stations were analyzed for estimating the industrial effluent loads. The obtained data revealed that food sector represents the highest load for BOD and TSS with values of 80 ton BOD/day and 2.33 ton SS/day. For selected industrial sectors, cost-effective technology is applied to reduce the loads on the centralized wastewater treatment plant (WWTP) as well as on the lifting stations. Inorganic polymeric ferric chloride (POFC) coagulant gives higher removal efficiency for TSS and COD without pH control. Moreover, the chemicals cost for treating wastewater is reduced by 40 % with using POFC instead of conventional coagulants.
