Food-processing plant

As the name implies, these operations, if uncontrolled, can cause a serious air pollution problem. The main problem is the odors associated with the process. Examples of such industries are tanning works, rendering plants, and many of the food processing plants such as fish meal plants. In most cases, the emissions of particulates and gases from such plants are not of concern, only the odors. Requiring these industries to locate away from the business or residential areas is no longer acceptable as a means of control. [Pg.90]

Sources of filth and contamination are diverse and numerous, each contributing its individual weight to the final summation and measurement. Rats, mice, and flies are themselves filthy in habit and also indicative of filthy conditions. Any evidence of their presence in or about a food product constitutes a heavy measure of filth. Insects which infest foodstuffs, or which live in or close to a food processing plant, create and leave evidence of their presence and reflect field, factory, and storage conditions. [Pg.62]

A purified water stream for a food processing plant is raised to required temperature by heat exchange with warm untreated process water. A conventional two-pass heat exchanger is to be used. This problem is based on the formulation of Walas (1991) and data taken from Backhurst, Harker and Porter (1974). [Pg.628]

In a food processing plant there is a requirement to heat 50,000 kg/h of towns water from 10 to 70°C. Steam at 2.7 bar is available for heating the water. [Pg.790]

Polar organic compounds such as amino acids normally do not polymerize in water because of dipole-dipole interactions. However, polymerization of amino acids to peptides may occur on clay surfaces. For example, Degens and Metheja51 found kaolinite to serve as a catalyst for the polymerization of amino acids to peptides. In natural systems, Cu2+ is not very likely to exist in significant concentrations. However, Fe3+ may be present in the deep-well environment in sufficient amounts to enhance the adsorption of phenol, benzene, and related aromatics. Wastes from resinmanufacturing facilities, food-processing plants, pharmaceutical plants, and other types of chemical plants occasionally contain resin-like materials that may polymerize to form solids at deep-well-injection pressures and temperatures. [Pg.801]

Oil-grease effluent is produced in municipal sewer, petroleum refineries, petrochemical plants, steel mills workshops, food-processing plants, and in the textile industry. [Pg.205]

Solid waste discharges from chemical plants can represent very large problems, especially from paper mills, plastics plants, and food processing plants. Some materials do not decompose in the environment, and can become burdens when they accumulate. Some polymers have backbones that degrade in nature, such as aliphatic polyesters and polyvinyl alcohols others do not, such as polyethylene and polystyrene. [Pg.299]

An important application of iodine is in water purification and sanitation. It is used as a disinfectant in food-processing plants, dairies and restaurants. It is applied to disinfect municipal and other water supplies and swimming pools. [Pg.397]

According to the developer, more than 300 of the patented ICEAS systems are in operation in applications such as treatment of municipal wastewater and high-strength industrial waste from chemical plants, tanneries, and food processing plants. [Pg.946]

The chief nonmineral application of froth flotation is to the removal or oil or grease or fibrous materials from waste waters of refineries or food processing plants. Oil droplets, for instance, attach themselves to air bubbles which rise to the surface and are... [Pg.638]

On occasions, animal feed has been suspected of deliberate contamination. Incidents involving contamination of animal feed by industrial by-products such as polycylic aromatic hydrocarbons (PAHs) and combustion products such as dioxins are not uncommon. A problem with animal feed is that there is sometimes inadequate control over the provenance of feed constituents. For example, spent cooking oil from food-processing plants is a legitimate feed component. Unfortunately, the temptation for the unscrupulous to dispose of other unwanted oils in this way is too great for some. In many cases such adulterants are probably diluted to such an extent that they are undetectable by conventional chemical analyses. Nevertheless, they may still represent a longterm cumulative hazard to consumers of products from animals fed on such material. [Pg.18]

Avoided water treatment costs. These costs will vary over a wide range depending on the process. For a food processing plant they are likely to be relatively modest—perhaps only US 1/1000 gal or less—but treating latex emulsion plant effluents (called white water) can cost as much as USS10/1000 gal or more. [Pg.270]
