Cleaning performance

Organic Additives. Certain nonsurfactant organic additives improve cleaning performance and exhibit other desirable properties. 

Lam, S.W., Soetanto, A. and Amal, R. (2009) Self-cleaning performance of polycarbonate surfaces coated with titania nanoparticles. Journal of Nanoparticle Research, 11, 1971-1979. 

Use just enough amount of enzyme in the product, since the cleaning performance of enzymatic stains increases with concentration but saturates at high enzyme concentration. 

Some stripper harvesters are equipped with onboard cleaners that have cleaning effectiveness of up to 50 percent. Their cleaning effectiveness depends, however, on machine adjustment and on other factors not yet identified. In one test, big differences in cleaning performance have been shown to exist between identical harvesters operating under Identical field conditions (2. This study is continuing and should lead to improved stripper-mounted cleaner performance.

Test function after cleaning, perform pH. Refer to attachment no. 2200.10(D). 

Alkalinity Boosters. It has long been known that many soils are sensitive to high pH. Fairly high levels of sodium carbonate, soluble silicates (ratio 1.6 to 3.2 SiOi to Na-O) and sodium mctasilicaic (NaiSiOrf are used lo supply alkalinity for improved cleaning performance.

Other important future membranes properties include improved resistivity to extreme pH enabling better cleaning performance and resistance to oxidizers, organic solvents and particulate fouling. More important properties exist, yet the most important may be the resistance to fouling of the different sources. 

Pressure vessels are usually constructed of fiberglass or stainless steel. Fiberglass is typically used for industrial, non-sanitary applications. Stainless steel vessels are preferred for sanitary applications, where high-temperature (up to 85°C) cleaning performance may be required. 

Detergent Builders. Builders are typically added to a detergent formulation to extend or improve the cleaning performance of a formulation across a wide range of use conditions. The combination of builders and surfactants exhibits a synergistic effect to boost total detergency and cleaning efficacy, as compared with an equal amount of either compound alone. The major properties and characteristics that are desirable... 

Spray-dried powders are formulated to give the best overall cleaning performance and flow characteristics at the lowest possible formulation costs. Typical spray-dried detergent formulations are shown in Table 36.6. Slurry preparation is considered to be the single most important factor in spray drying. Control of the raw material order of addition, slurry solids level, slurry temperature, viscosity, and aeration enable manufacturers to deliver the desired final product characteristics. The spray tower itself is simply a contained heat source that removes moisture at a uniform rate dependent upon the quality and the quantity of feed to the dryer. If feed variables are not controlled, variability in the... 

The selection of an aqueous cleaning system is simplified if only water alone, or water and a commodity chemical alone, are used. The cleaning performance can be somewhat predicted based on solubility characteristics (at the appropriate pH) or by consideration of the peptizing performance of alkalinity on protein or the oxidizing action of sodium hypochlorite on denatured protein. In the case of formulated multifunctional cleaning agents, the performance is more... 

In certain circumstances, water quality can be critical for cleaning performing. If the washing step involves... 

The concentration of pollutant strongly depends on the gasifier and the gas cleaning performance as well as on the amount of wastewater generated. ... 

Washing is the countercurrent or cross-current cleaning performed by dissolving impurities in suspensions or crystal/amorphous solid slurries. The objective is to use a series of centrifuges to enhance the purity of the solids or to minimize the amount of wash liquid.
