It has excellent COD removing & De-coloring effect and can substancially reduce turbidity.
Very effective in eliminating N-Hexane & ABS (Anion Surfactant)
Can be applied in wide pH range pH 3 – 11
It is a basic pre-treatment chemical covering 50-90% effectiveness.

2. Properties

Appearance Grey or Dark powder
Flash Point Inflammable
Packing 20 Kg paper bag

3. Process Flow

Collection of waste water Add Chemicals (1st Reaction) Add Chemicals (2nd Reaction)
Coagulation Precipitation Discharge

4. Usage

Using together with AI2(SO4)3 or Ferric Salt gives more efficiency.
In order to determine standard dosage, put 2000 ppm (2g/liter of waste water)of Agent together with inorganic flocculant into the test jar containing 1 liter of waste water. However, it is recommended for enough jar test, starting input from 500 ppm onwards until desired result is obtained.
Stir the jar about 30 minutes.
Increase the dose of Agent if it is not enough to produce the desired effect.
If 80-90% of impurities are removed, then the dosage could be considered as standard input ratio.
