Wastewater polluted

This section describes the treatment techniques currently used or available to remove or recover wastewater pollutants normally generated by aluminum forming facilities. In general, these pollutants are removed by oil removal (skimming, emulsion breaking, and flotation), chemical precipitation and sedimentation, or filtration.6- 3... [Pg.219]

This section describes the treatment technologies currently in use to recover or remove wastewater pollutants normally found at coil coating facilities. The treatment processes can be divided into six categories recovery techniques, oil removal, dissolved inorganics removal, cyanide destruction, trace organics removal, and solids removal.5-14 Adoption of specific treatment processes will depend on the following ...

For removing low levels of priority metal pollutants from wastewater, using ferric chloride has been shown to be an effective and economical method [41]. The ferric salt forms iron oxyhydroxide, an amorphous precipitate in the wastewater. Pollutants are adsorbed onto and trapped within this precipitate, which is then settled out, leaving a clear effluent. The equipment is identical to that for metal hydroxide precipitation. Trace elements such as arsenic, selenium, chromium, cadmium, and lead can be removed by this method at varying pH values. Alternative methods of metals removal include ion exchange, oxidation or reduction, reverse osmosis, and activated carbon. [Pg.533]

Ozone is used in the treatment of drinking water and in industries where high purity water is required (e.g., breweries, pharmaceuticals, and electronics). Ozone is also used in industrial wastewater pollution control, wastewater disinfection, and odor control in the treatment of process water, such as cooling tower water in the treatment of swimming pools and spas in pulp bleaching and in organic synthesis, as a selective oxidant.

Domestic wastewaters, polluted surface waters, or the effluents from biological waste treatment plants are sources of high microbial populations. When such seeded dilution water is used, the BOD is calculated as follows ... [Pg.188]

Using this procedure, Roche successfully operated a pilot plant for a capacity of tonnes/day for several thousand hours. By adding very small amounts of Ni salts, it was possible to maintain the anode activity over long periods. The electrochemical process is said to be superior to the conventional hypochlorite process, particularly because of the low level of wastewater pollution 286). However, it appeared not to be sufficiently attractive from an economic point of view to be implemented on an industrial scale in the new Roche plant in Scotland. [Pg.32]
