It also provides a non-chemical pressure test of the CIP flow path. Caustic solution single pass flush through the vessel to drain. Caustic is the main cleaning solution. Caustic solution re-circulation through the vessel. Intermediate WFI or PW rinse; Acid solution wash – used to remove mineral precipitates and protein residues.
Soft washing is a cleaning method using low pressure water. More recently, the term "softwashing" has been used to describe any form of spraying chemicals at buildings where solutions (typically sodium hypochlorite based softwashing chemicals) are used to remove mildew, bacteria, algae and other organic stains from roofs and other building exteriors.
TAPS ([tris(hydroxymethyl)methylamino]propanesulfonic acid) is a chemical compound commonly used to make buffer solutions. It can bind divalent cations, including Co(II) and Ni(II). [1] TAPS is effective to make buffer solutions in the pH range 7.7–9.1, since it has a pK a value of 8.44 (ionic strength I = 0, 25 °C). [2]
A pressure washer is used to remove old paint from a boat. Patio flagstones being pressure washed using a rotary nozzle. Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces.
In industrial scale water softening plants, the effluent flow from the re-generation process can precipitate scale that can interfere with sewage systems. [3] The slippery feeling associated with washing in soft water is caused by the weaker attraction of the soap to the water ions when the water has been stripped of its mineral content.
McIlvaine buffer is a buffer solution composed of citric acid and disodium hydrogen phosphate, also known as citrate-phosphate buffer. It was introduced in 1921 by the United States agronomist Theodore Clinton McIlvaine (1875–1959) from West Virginia University , and it can be prepared in pH 2.2 to 8 by mixing two stock solutions.

An aqueous-based parts washer is much like a large dish washer. It uses water and detergent combined with heat and mechanical energy to provide the cleaning action. There are two main process styles of aqueous parts washers, the jet spray process and the power wash process. In a cabinet parts washer, the parts are placed on a turntable and the ...
