Automatic Large Type Sodium Hypochlorite Wastewater Treatment For Sewage Plant

Disinfection method

On-site
Sodium hypochlorite

commercial
sodium hypochlorite

UV

Making process

It produce a solution of

strengths 0.8% and the only
raw materials required are
salt and water and electricity, so it has a

PH of 9 and making it less likely to cause scaling

By-product of the chlor-alkali industry, the concentration of 10%, containing excess alkali and harmful impurities

Generally within the ultraviolet fluorescent mercury released from plasma discharge.

attenuation

Without attenuation

Attenuation of 5% per day, and also cause excessive Chlorate in dinking water

Usually by the turbidity impact, gradually weakened life six months after the exposure time is short, there is no continuous disinfection capacity, and there may be a problem microorganisms resurrection light, preferably in the case of process water for immediate use, no secondary pipeline better raw water pollution and biological stability of the situation (generally require organic matter content of less than 10μg/L)

safety

Safety disinfection method, environmental non-toxic, liquid dosage

Dangerous articles. Risk during transport and storage and easily caused degradable when storage. Short time storage and high transport costs. Liquid dosing

Quartz tube require regular cleaning, heavy workload, each lamp should change the water. Easy to do radiation uniformly over the entire processing space, shaded area exposure

Disinfection by-products

Due to weak in chlorine oxidation ability, three material are less, and combined additive, ammonia, potassium permanganate, less by-products

The raw material is

Industrial salt, which contain harmful impurities in drinking water and it is bad for health.

None

Economic analysis

The investment is a little higher in the early time, but the operation cost is low, and after three or four years it can pay your investment money back

Equipment cost is low, but the high cost of running, and the running costs can not be controlled

Early investment in small, high maintenance costs, large daily operating costs.

Dosing Accuracy

Dosing liquid low concentration, can accurately control the amount of chlorine

High concentration, difficult to precisely control the amount of chlorine, dosing hole easily plug fouling

Regular cleaning, the effect can not be controlled and also need regular to test water quality.
