Water treatment agent suitable for inorganic effluent

Water treatment agent suitable for inorganic effluent

Water treatment agent suitable for inorganic effluent combining three functions: coagulation, flocculation and improved dewatering performance.

  • Product name
    PL-A510
  • Features
    • Having excellent performance for coagulation, flocculation and improved dewatering performance due to its natural plant ingredients.
    • Reducing the consumption of inorganic flocculants and neutralizing agents due to high coagulation and flocculation performance which are achieved by using water-soluble polymer derived from natural plant.
    • Reducing the amount of sludge to be discharged by minimizing the quantity of inorganic flocculants and neutralizing agents, both of which form the greater part of the sludge weight.
    • Contributing to reducing dewatering processing time and sludge treatment cost due to the high water flow performance, which is achieved with the fibrous structure of natural plants.

[Recommended use condition]
• As general polymer flocculants are used, add a solution of this product to water to be treated.
* The optimum additive amount depends on the contaminant types and concentration; a guideline is about 3 to 10 mg/L of solid content.

[Dissolution method as a reference]
• Dissolve this product in water so that the solution has the following concentration:
- If the solvent is pure water: 0.1 wt%
- If the solvent is not pure water: 0.2 wt%

* As general polymer flocculants are used, when making a solution, add this product to water a little at a time, stirring the solution so as not to form lumps.
* Although insoluble reddish brown fine particles may be suspended, use the solution as it is.
(These are substances needed to improve the ability of dewatering sludge.)

Suitable for inorganic effluent water treatment, for example at plating factories.

- Existing facilities can be used for this process without modification.
- Add this product after adding the inorganic flocculant.
- Although it contains insoluble components derived from plant, use it as is.
