Fungicides Analysis for Water Treatment Agents

Fungicides are usually chemical agents that effectively control or kill microorganisms - bacteria, fungi and algae - in water systems. Fungicides are chemicals that inhibit the growth of bacteria and algae and microorganisms in water to prevent the formation of microbial slime that can be harmful to the system. Including oxidizing biocides, such as chlorine, sodium hypochlorite, bleach, ozone, chloramine; non-oxidizing biocides, such as dodecyldimethylbenzylammonium chloride, dodecyldimethylbenzylammonium bromide, dithiocyanomethane; heavy metal compounds, such as mercuric oxide, mercury chloride, mercury fluoride; slime biocides, such as rosinamine, hydrogen peroxide, biguanide polymer.

Applications of Fungicides

Fungicides in water treatment is mainly used to clean ultrafiltration membrane. Ultrafiltration device in the long-term water production process, due to the high content of organic matter in the feed water, under certain conditions, there will be some bacteria and algae breeding in the membrane components, so that the filter membrane clogging, resulting in water permeability pressure increases, the quality of water production decreases, and in order to restore the headstrong membrane water throughput and the ability to retain impurities, it is necessary to regularly use fungicide on the membrane components for chemical cleaning.

Testing items

Bactericidal effect testing, concentration testing, active ingredient testing, active substance testing, bactericidal rate testing, efficacy testing, heavy purity testing, ingredient content testing, ingredient analysis.

Action Mechanism of Fungicides

1. Interfere with the respiratory process of the germ and inhibit the production of energy.
2. Interfere with the biosynthesis of bacteriophage vital substances such as proteins, nucleic acids, sterols, etc. Most of the protective fungicides are broad spectrum and low bactericidal power of the product. Endosmosis fungicides are generally stronger, the fungicidal spectrum is narrower, some of which have a specific selection of pathogenic bacteria toxicity. As the endosorbent in the body of a single point of action, the bacteria are prone to genetic mutations and resistance. In order to avoid or delay the emergence of resistance, you can usually choose the appropriate protective agent and endosorbent mixed application or rotation, so that you can complement each other to get a better control effect.
