◐ Product Summary

HOC SERIES were developed to increase the economy and efficiency when used at sites as alternatives to inorganic coagulants such as aluminum sulfate(liquid cake, solid cake), PAC, and ion salt which are now generally used in waste water disposal plant. Our Company’s HOC SERIES can obtain excellent results with the input of 1/5~1/10 of the amount of general inorganic coagulant. As there is no need to input neutralizing agent or only a small amount of them is sometimes needed, the treatment coat is greatly reduced.
Composition
  • apparence : citrine liquid
  • main components : chitosan added compound
  • specific gravity : 1.3 ± 0.1
  • pH : 3.0 over (10% solution)
 
Application

electronic / food oil

refinery/ chemical

Steel making

Paper manufacture

Usage


Injection of Undiluted

Solution or use Diluted

Input


Depending on the waste water

50 ~ 300ppm

Characterization of product


1. Reduces sludge generation by more than 30%

2. Chemical consumption is 1/5~1/10 of those of the existing inorganic coagulant

3. Depending on the condition of the waste water, neutralizing agents are not always needed

4. Efficiency of waste water treatment increases by 10%

5. The work is made easier than that in existing inorganic coagulants

6. Prevents the deterioration of facilities as the corrosiveness and oxidation properties are low

7. Additional effects (reduction of costs of seeding and electricity) due to the increase of

  chemical treatment efficiency
