An industrial waste water treatment process including a step of guiding a waste water from chemical solution treatment troughs by a gutter into a waste water reservoir through a wire gauge filter; a step of adding a chemical solution, which contains NaOH and H 2 O at the ratio of 25:75 ...
Boiler water treatment has basically three phases. First, we process the raw water to remove impurities like organics to the desired cleanliness. Second, we remove hardness i.e. minerals and metals to create less favorable conditions for deposition. Finally when the water is added to the boiler...
Development of electric rust preventive machining method –Proposal for a machining water recycling system– As machining fluid contains oil, extreme pressure agents, surface active agents, etc., effluent treatment of waste fluid is necessary, such as incineration... N Nishikawa,Y Sato,T Katou,.....
Typical POU systems contain water treatment technologies such as media filtration, reverse osmosis (RO) membranes, UV disinfection, and remineralization (particularly after RO)11. Large particles, rust, and debris are first removed by filtration through string-wound sediment filters. Next, some form o...
ULF treatment uses ULF waves to promote formation of black Magnetite, Fe3O4instead of normal red rust, Fe2O3, this micro layer of magnetite protects the steel surface from further corrosion. Once the ULF treatment is fitted it protects the steel surface 24x7 without any need for routine mon...
The device for water treatment on the basis of an external electromagnetic effect on water, for purposes of an improved calcification and rust resistance of pipes, fittings and other devices, operates with a voltage in excess of 12 volt. The preferred voltage values are 24, 48 and 96 volt.收...
In addition, this understanding alerts those in management to the related hazards and provides encouragement to take corresponding measures as early as possible, providing a certain theoretical basis for later prevention and comprehensive treatment.
Conventional water treatment often calls for complex multistage processes (namely coagulation, disinfection, flocculation, sand filtration, screen-filtration, ozonization, sedimentation) and requires a wide array of chemicals (namely chlorine, flocculents, hydrogen peroxide, lime, ozone). The processes ...
Researchers on metallic iron (Fe0) for environmental remediation and water treatment are walking in a valley of confusion for 25 years. This valley is characterized by the propagation of different beliefs that have resulted from a partial analysis of the Fe0/H2O system as (1) a reductive chemi...
