Selection and Use of Fungicides

Water treatment chemicals include flocculants, scale inhibitors, corrosion inhibitors, and bactericides. These Water treatment chemicals remove suspended solids and poisonous things through the water. Controls dirt, forms sludge and reduces corrosion of water-contacting materials. Deodorant disinfection, bleaching, softening, stable water quality and desalting.

The performance of the water treatment chemicals largely determines the operation of the process, the final water quality, and the cost of the enterprise. Therefore, it’s very important to select an excellent water treatment agent manufacturer. Consider a look at the introduction of water treatment knowledge.

A bactericide can be a chemical designed to inhibit the growth of microorganisms like algae in water to stop the formation of microbial slime. Bactericides are often classified into two types: oxidizing bactericides and non-oxidizing bactericides.

Oxidizing bactericides, for instance commonly used chlorine gas, sodium hypochlorite, bleaching powder, etc.; non-oxidizing bactericides have good effects and so are commonly used within the cell wall and cytoplasmic chemicals that will destroy bacteria, like quaternary ammonium salts.

Among the list of quaternary ammonium salts, like Benzalkonium Chloride. many times, it has a number of effects such as sterilization, peeling, and corrosion inhibition. Benzalkonium Chloride has a good prospect and it has been put on to oilfield water and industrial cooling water.

1.Selection and Application of Fungicides

The choice of fungicide relies on water quality, the kind of bacteria, especially the pH value.

As soon as the pH is high, it’s not preferable to use an oxidizing biocide such as chlorine. The higher the pH of the quaternary ammonium fungicide, the better.

When Fe2+ and H2S are incorporated into water, it is not better to use an oxidizing biocide. Otherwise, it will not only increase the quantity of oxidizing biocide but also affect the water quality of sewage treatment.

The bactericide is compatible with other Water treatment chemicals, and the reaction doesn’t cancel each other out. It has good solubility. After adding, it doesn’t affect the water quality. It can not raise the volume of colloidal particles in water, can dissolve water evenly, and is clear and transparent.

Different types of fungicides really should be selected at the same time within the same sewage treatment system in order to avoid bacterial resistance, high toxicity, low toxicity, easy degradation and no polluting the environment.

2. The Addition of Fungicides

Approach to addition: continuous addition and control increase in the volume of bacteria. In addition to intermittent impact dosing, large doses increase kill a large number of bacteria. This requires a variety of the two.

Dosing point: generally found at the far end of the sewage treatment system, for example, the incoming water (prior to tank). In order to ensure the water quality of the water injection, the dosing point is normally set following the filtration in the sewage treatment or the inlet on the water injection pump.

Dosing amount: continuous dosing, the starting concentration is higher, and also the volume of bacteria is controlled, and the relatively low dosing concentration is adopted. Effective concentrations were based upon laboratory evaluation and on-site bacterial analysis. Intermittent impact dosing, regular use of higher concentrations.

The bactericide is sterilized by way of a sewage treatment system. Dosing cycle, dosing amount, dosing time, based on indoor evaluation and on-site bacterial analysis, adjusted by field practice. Bacterial Quantity Monitoring After adding the fungicide, water treatment system ought to be sampled regularly.

As well as the bacteria count in accordance with the conventional method. The dosing method and also the dosing concentration could be adjusted at any time to ensure the sterilization effect of the fungicide.
