The paucity of proper sanitation facilities has contributed to the spread of waterborne diseases in many developing countries. The primary goal of this study was to demonstrate the feasibility of using a wastewater electrolysis cell (WEC) for toilet wastewater disinfection. The treated wastewater was designed to reuse for toilet flushing and agricultural irrigation. Laboratory-scale electrochem...

Thermophilic treatment is one of the advanced treatment technologies used for the purification of high-strength wastewaters. Thermophilic systems are conventionally used for sludge treatment, but their ability to reduce COD to a great extent with sludge generation one-tenth when compared to the other wastewater treatment technologies, have favored its application for wastewater purification. Mo...

Textile industry can be classified into three categories viz., cotton, woolen, and synthetic fibers depending upon the used raw materials. The cotton textile industry is one of the oldest industries in China. The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and finishing processes. Wastewater from printing...

Across the nation, food service establishments using onsite wastewater treatment systems often experience pretreatment system and/or drain field performance problems. This study used statistical analysis of restaurant management practice and primary cuisine type to observe their influence on five-day biochemical oxygen demand (BOD5), total fats, oils, and greases (FOG), total suspended solids (...

A significant nutrient load can be generated internally by publicly owned treatment works (POTWs). These nutrients can be found in the reject water, also known as side streams, of many municipal wastewater and sewage sludge treatment processes. These side streams include the reject stream from membranes, supernatant liquid from sludge digesters, and the centrate/filtrate return stream from sewa...

1 By Keith Dunne and John F. Russo C losed-loop water recycling is only one of several alternatives available when converting. to aaueous or semiaqueous cleaning. Most CFC users have been accustomed to operating a mature and well-defined process. Conversion to other cleaning technologies has forced users to develop entirely new skills and to develop a good working knowledge of the chemistry of ...

Anaerobic wastewater treatment differs from conventional aerobic treatment. The absence of oxygen leads to controlled conversion of complex organic pollutions, mainly to carbon dioxide and methane. Anaerobic treatment has favourable effects like removal of higher organic loading, low sludge production, high pathogen removal, biogas gas production and low energy consumption. Psychrophilic anaero...

In Europe the last two decades has witnessed growing water stress, both in terms of water scarcity and quality deterioration, which has prompted many municipalities to look for a more efficient use of water resources, including a more widespread acceptance of water reuse practices. This paper reviews European water reuse practices and sets out the map of the water reclamation technologies and r...
