Toxicity One of the advantages of quaternary ammonium disinfectants is that they don't damage clothing and carpets the way that bleach does. As they have been shown to stop cells taking in oxygen, and also cause amino acids to leak out of cells, it’s thought they likely work in some way by adhering to the surfaces of cells. 1:10 (~5000ppm free chlorine) Clorox, household bleach, … Though the exact mechanisms of action is unknown, they work primarily by destroying proteins in cells. When the solvent is very hard water (high pH) is likely to be added to the acid in advance, to be effective. The advantages of ozone are: Safe and easy in use Low maintenance costs Ozone is produced on-site and requires no storage of dangerous chemicals. Soda ash can be used to neutralize the pH, because the soda ash will increase the pH of the water. The solution makes Sanitary: In doing sanitation, sanitary solution should be made in advance in accordance with needs. So the higher the levels of hypochlorite in solution, the higher the pH. With higher pH, the effectiveness of the disinfectant will be much reduced, because the levels of HOCl will be reduced. They work by disrupting cell walls and membranes, and reacting with proteins and enzymes. Advantages + wide spectrum of antimicrobial activity + readily miscible with additives (e.g. Advantages. Phenol is no longer used as a disinfectant due to its toxicity and carcinogenicity. Waste waters treated with this disinfection do not contain chlorine or chlorinated disinfection by-products, thereby making dechlorination unnecessary. HOCl formation depends on the pH, the pH between 4-5, HOCl formation will occur optimally. Formaldehyde, a simple but important member of aldehydes, is highly reactive due to its strong electrophilic properties. The characteristics of few commonly used chemical disinfectants … The following table shows these advantages and disadvantages. So it is recommended for use at temperatures of 20-25 ° C.
