Lesson D1 Guidelines and Standards for Wastewater Reuse
Due to water shortage, wastewater reuse has gained great importance in many parts of the world. Wastewater reuse practices have become valuable source in water resources management. As an independent source of water, reclaimed water can increase the reliability of water supply. Reclaimed wastewater requires effective measures to protect public health and the environment. Strong wastewater reuse guidelines and regulations are developed for the purpose. It is difficult to establish wastewater guidelines and regulations that can suit all regions in the world. Among the broad reasons for this as limiting factors, are economics of countries relating chosen treatment technologies and additionally, the local context of a region must be taken into consideration in settings. Almost all wastewater reuse guidelines and regulations are bacteriological-based. Some of them consider biochemical parameters. In this lesson you will comprehend the importance as well as the necessity of setting wastewater reuse guidelines and regulations. You will be aware of arising problems
for getting universal valid standards. You will get an overview of guidelines and regulations existing worldwide and regionally.

Advanced Treatment Technologies For Recycle/Reuse Of Domestic Wastewater
Conventional wastewater treatment technologies improve the quality of wastewater discharged into the environment and restrain polluted waters from contaminating other available clean water resources. However, these treatment technologies do not make wastewater fit for further beneficial uses in communities closer to the points of generation. Innovative and advanced technologies that can further improve the quality of wastewater are needed to overcome this limitation of conventional technologies, and to promote widespread adoption of recycle and reuse practices. Advanced treatment processes can be biological processes, physicochemical processes, or a combination of both (hybrid processes). Biological processes to remove nutrient pollutants such as nitrogen and phosphorus, provide the platform for further wastewater treatment to reusable quality. Physicochemical processes such as deep-bed filtration, floating media filtration, and membrane filtration, play a major role among treatment technologies for water reuse. Membrane filtration has significant advantages over other processes since they produce high quality effluent that requires little or no disinfection with minimum sludge generation. The hybrid processes attempt to obtain the benefits of both biological and physicochemical processes in one step.

Chemical Cleaning Of Ultrafiltration Membrane After Treatment Of Oily Wastewater
Abstract:
Oily wastewaters and Oil–in-water emulsions are two of the major pollutants of the environment. Ultrafiltration (UF) membranes play an important role in the treatment and reuse of oily wastewaters. Fouling of UF membranes is typically caused by inorganic and organic materials present in wastewaters that adhere to the surface and pores of the membrane and result in the deterioration of performance with a consequent increase in energy costs and membrane replacement. In the experiments, polyacrylonitrile (PAN) and outlet wastewater of the API (American Petroleum Institute) separator unit of Tehran refinery as membrane and feed were used, respectively. Fouling and cleaning experiments were performed with oily wastewater and selected cleaning agents using a laboratory scale cross flow test unit. The results showed that metal chelating agent (ethylene diamine tetra acetic acid disodium salt-2-hydrate (EDTA)) and an anionic surfactant (sodium dodecyl sulfate (SDS)) were able to Clean the fouled UF membrane effectively by optimizing chemical (pH) and physical
(cleaning time, cross flow velocity (CFV) and temperature) conditions during cleaning. Flux recovery and resistance removal were found to improve with increasing CFV, temperature, pH, cleaning time and concentration of the cleaning chemicals. In this paper, the cleaning mechanism is also investigated.
