[Product Description] E-PAM (Emulsion-Polyacrylamide)

E-PAM (Emulsion-Polyacrylamide) of Hansol Chemical was developed through partnership with advanced technology of overseas and a next generation product. Compared with current powder and dispersion type product, it has an excellent flocculation performance, fast dissolution characteristic and economically efficient disposal method.

In particular, emulstion polyacrylamide produced by Hansol is such an advanced product that it can be widely applied to public facilities including industrial wastewater area of dye/textile, papermaking, leather, food, petrochemical, mine industry, urban sewage treatment plan and sanitary treatment
plant.

I. Characteristics of E-PAM of Hansol Chemical

  1. Fast dissolution, easy to use, compared to P-PAM.
  2. Emulsion type allows to automate your factory facilitie.
  3. Applicable throughtout the whole process such as pressure flotation, flocculation, precipitation, condensation, dehydration, etc. 
  4. Selectible among various grades of the product according to the process that the customers take.

II. How to use E-PAM of Hansol Chemical

  1. Dissolve - Dilute E-PAM with regular industrial water to 0.2~0.5%. Dissolve compltely stirring for 30~60 minutes before use. 
  2. Injection - Shake or stir before use, in case of phase separation behavior.
  3. Amount of Injection - Depending on the circumstances and types of waste water, use E-PAM up to 15ppm during the first flocculation and precipitation process. Use 300ppm to the maximum while dehydrating.

III. Competitiveness of E-PAM of Hansol Chemical

1. Pros/Cons
  1) Emulsion
    (1) Pros
        - Complete automation helps man power usability efficient.
        - No dust, clean and safe.
        - Storage tank helps save space.
        - Able to change concentration (0.2~1.0%) depending on the required process.
        - Centrigual easily with cross-linked molecular structure
        - Much more excellent condensation and centrifugaling.
    (2) Cons
        - Freezing problems under -30 degree celcius.
        - Short storage period compared to powder type.
  2) Powder
    (1) Pros
        - Massive amount to store/long-term storage
        - No freezing problems
    (2) Cons
        - Dust inhaling might cause industrial disaster
        - Not elidgible for automation, long time to dissolve (2~3hrs), insoluble portion appears.
        - Excessive invest funds needed compared to emulsion type.
        - Unnecessary space needed for storage.
        - Unable to reach high concentration (more than 0.4%).
        - Linear molecular structure results inefficient rate of centrifugal concentration and dehydration.

2. Competitiveness of Emulsion
  1) Various grades - Easy to adopt to changes. Various molecular structures that fit for each fields.
  2) Convenience - Complete automation, no manpower needed.
                           - Stable operation for 24-hour long.
  3) Cheap investment cost on facilitation - sewage treatment facility is cheaper than it is with powder.
  4) Technical service - the best techniques. Responsibility and total management.
  5) Harmless to human - No dust, bulk supply enhances work environment.
  6) Job security - No accident due to exposure of the dust.
