The Impact

Abstract Development of greener water treatment technologies is important for the production of safe drinking water and water security applications, such as decontamination. Chlorine assisted disinfection is common and economical, but can generate disinfection byproducts (DBPs) that may be of health concern. DBPs are formed due to the reaction of chlorine with naturally occurring organic and inorganic substances in water. Currently, various innovative technologies are being developed as alternative approaches for preventing DBPs during water treatment. In this study, we evaluated the effectiveness of a novel combination of high efficiency flow filtration and UV disinfection treatment system for the removal of Bacillus globigii (B. globigii) spores in water. The filtration system consists of a charged membrane filter (CMF) that not only helps to remove suspended particles but also reduces the impact of other impurities including bio organisms. In order to get most performance details, the CMF was evaluated at clean, half-life, and end of life (EOL) conditions along with 100% UV transmittance (UVT). In addition, the effectiveness of the UV system was evaluated as a stand alone system at 100% and 70% EOL intensity. The study was conducted at the US EPA's Test and Evaluation (T&E) Facility in Cincinnati, OH, using B. globigii, a surrogate for B. anthracis spores. This non-chemical environmentally-friendly CMF/UV combination system and the stand alone UV unit showed greater than 6.0 log removal of B. globigii during the tests.

With the development of industry and technology, the need for freshwater increases day by day, the contradiction between the fresh water for production and livelihood is sharpened. An important way to solve the problem is desalinization of the groundwater. In this paper reverse osmosis disposal process of groundwater are used, PLC are used to control electromagnetic valves and water pumps in the desalinization water treatment system and automatic switching state or stop. Using touching screen as man-machine interface, which is more convenient for the operator to know the working stages, and is more facility for desalinization process. The system has many advantages, such a saving energy, high efficiency, more safety, control modes flexible and various, function extension easily. It has great significance in reduce cost of desalinization of groundwater and remission serious lack of the freshwater in some areas of China.

In this study, a novel combination of ultrasound with acid for coagulant recovery from drinking water treatment plant sludge (DWTPS) is investigated in view of improving the coagulant recovery efficiencies. Optimal recovery conditions, a sulfuric acid concentration of 2.0 M, an ultrasonic treatment time of 30 minutes, an ultrasound power of 1000 W and stirring speed of 1000 rpm, have been found in the lab test. The aluminum recovery rates from acidification process with assistance of ultrasound increased by approximately 20% compared with that of acidification only. It was found that the synergistic effects between acid with ultrasound contribute to improving the treatment efficiency.
