Water nonpotable

A facility drawing water from a stream or lake should either have independent locations from which to draw from or have a back-up supply from the city system or a private well. Care should be taken when using potable and nonpotable sources so that cross-contamination does not occur.

Just as water is an integral part of any food, the supply, quality, and disposal of water is of prime consideration in the establishment and operation of all food processing. Potable (drinkable) water may be required for addition to the product, and will certainly be required for cleanup. Nonpotable water may be required for heat exchangers and cooling towers. Boiler feed water must be conditioned within close limits of pH and hardness. Brennan et al. (1990) in their book Food Engineering Operations list four types of water used in the food and beverage industries ... 

With world population increase and scarcity of water sources, the key to providing a sustainable development of water resources is to carry out water reclamation. The concept of water reclamation is to treat wastewater from different sources to meet different water quality requirements of various water applications economically. USEPA provided guidelines for nonpotable water reuse,which stated various conventional technologies commonly used in treating municipal wastewater such as primary and secondary treatment, and specified the... 

With the advancement of membrane technologies and engineering in the integration of MF, UF, NF, and RO membrane systems, and possibly a liquid membrane system, wastewater reclamation can provide high quality water for underground water replenishment and direct household nonpotable use, and source water for ultra-pure water applications. Membrane technology provides several advantages over conventional treatment processes ...

Chloroethyl vinyl ether in potable and nonpotable waters and solid and hazardous wastes may be analyzed by EPA Methods based on GC and GC/MS instrumentation (U.S. EPA 1992 1997 Methods 611, 625, 8010, 8270) using a purge and trap or thermal desorption technique. Characteristic masses to identify this compound by GC/MS using electron-impact ionization are 106, 63, and 65.

Phenols are widely used in industry. The three major classes of phenolic compounds of commercial applications are alkyl phenols, such as cresols and pyrogaUol chlorophe-nols and nitrophenols. The industrial uses of these compounds are described in this chapter, under individual headings. Because of their widespread uses, these substances occur in the environment in air, groundwater, wastewater, and soils. Pentachlorophenol produced during the incineration of municipal refuse could react with different fly ashes at 250-350°C (482-662°F) and form dioxins (Karasek and Dickson 1987). The EPA has listed some of these substances as priority pollutants in potable and nonpotable waters... 

The chemicals in water may be inorganic elements or molecular species. Inorganic chemicals characteristic of groundwaters and surface waters are different. The importance given to the type of chemical contaminant present is dependent primarily on the potential health risk associated with it. Arsenic, barium, cadmium, and chromium are potentially carcinogenic elements. Mercury, lead, and selenium also have been proven to be toxic. These elements and their molecular species are high priority contaminants because their presence even in very small amounts could render the water toxic and nonpotable. 

Wastewaters are also a part of this area. Included are all areas that remain underwater for periods longer than a few hours at a time. Potable and nonpotable water, sanitary sewage, and industrial waste liquids are all included.

The multiple tube fermentation method requires the use of replicate tubes and dilutions of samples. The fermentation products of lactose include mixed acids and gas, which is usually detectable. Coliforms are reported in terms of MPN of organisms present. MPN tables are based on a random dispersion of coliforms (Poisson distribution). Failure to shake the samples very well will result in a nonrandom distribution that will underestimate the actual density of the bacteria. If testing drinking water, a single bottle containing 100 mL may be used or 5 replicate tubes with 20 mL each or 10 replicate tubes with 10 mL each. If testing nonpotable water such as salt water, brackish water, or sediments, multiples and subsamples of 10 mL (e.g., 0.1 1.0 10 mL) should be used.
