Laundry operators

Other problems with ion exchangers include coating of the resin beads or zeolite particles with suspended matter from turbid water (pretreatment with a coagulant may be necessary) or algal growths (chlorination of the water may be required). Zeolites may cause significant silica carryover and should not be used to treat boiler water for steam turbines. Finally, although Ca2+ and Mg2+ are objectionable in boiler or laundry operations, they are necessary nutrients in the human diet. Furthermore, excessive consumption of Na+ can contribute to hypertension and other blood circulatory problems. In Canada, for example, the incidence of heart disease and related health problems is lower in areas where the water supply is... 

CNC Antifoam 1-A may be employed in any type of laundry operation wherein excessive foaming is a problem. The use of one to five ounces CNC Antifoam 1-A per 100 gallons of water will reduce foam which is particularly injurious when laundering equipment is employed for dyeing purposes. 

CNC Antifoam 1-AP may be employed in any type of laundry operation wherein excessive foaming is a problem. 

Fortunately, the laundry wastewater is mixed with general water in the public sewage and in the sewage treatment plants. As a result of dilution, both temperature and the high pH value of wastewater are considerably decreased. In addition, if laundry wastewater was treated separately, major problems would be encountered in dealing with the load of organic pollutants introduced by household and commercial laundry operations [4]. 

SOur. (1) Any substance used in textile or laundry operations to neutralize residual alkali or decompose residual hypochlorite bleach. The commonly used sours are sodium bifluoride and sodium fluosi-licate. (2) Contaminated with sulfur compounds, e.g., gasoline or natural gas. (3) Taste characteristic... 

Boiler tubes are often cleaned with EDTA or NTA solutions to remove both CaC03 scale and corrosion products. In pressurized heavy water nuclear power reactors, radioactive corrosion deposits (in effect, magnetite in which some of the Fe has been replaced by radioactive Co ) can be removed from the coolant water circuits with an aqueous mixtiu e of oxalic and citric acids (both good chelators for Fe " ") and EDTA. In home laundry operations, bloodstains on clothing can be removed by treatment with oxalic acid, which takes up the iron from the hemoglobin (Section 8.2) as Fe(ox)3 . By the same token, oxalates axe toxic when taken internally, as are many other complexing agents. For example, EDTA is used as a means...

A) Titration with calcium chloride. As was indicated above, these phosphates are widely used in laundry operation and in soap powders, to prevent the calcium and magnesium ions of hard water from giving a precipitate with the soap. The value of a particular phosphate for this purpose depends not only on the amount of calcium or magnesium the phosphate can take up to form a complex ion but also on the stability of this complex. In the procedure to be described, the amount of calcium salt needed to destroy a lather of soap and water containing phosphate is measured. This procedure gives an estimate of the calciumbinding power of the phosphate for this particular application.

Amine oxides are well known for their ability to remove oily/greasy soils from hard surfaces. This ability is retained in the laundry operation. Amine oxides have the general Structures A and B shown in Figure 14.20 Polymers with amine oxide units have also found utility in laundry detergents to increase detergency, i.e. 

There are two types of lanndry operations that are very common in the I I segment. Some big establishments such as hotels and hospitals typically have laundry operations done on their premises, whereas smaller outfits can have their laundry operations done off-site and often contracted out.
