Chemtex’s Poly Electrolytes or Poly Acrylamides improve the performance of waste water process and clarifier operation, thus producing less carryover and foaming, lower B.D.P., drier sludge and removal of offensive odors.



Polyelectrolyte is a long chain of repeating monomers (electrolyte). They are available in white powder. Polyelectrolytes when dissolved in water get charged due to the presence of the electrolyte group, and hence they help in neutralization of the suspended colloids or the small flocs produced after coagulation. The high molecular weight of polyelectrolytes aid in fast settling of the flocs.  

There are 4 types of polyelectrolyte used in water treatment industries.
·         Anionic Polyelectrolyte –  Negatively charged.
·         Cationic Polyelectrolyte – Positively charged.
·         Nonionic Polyelectrolyte – No charge.
·         Amphoteric Polyelectrolyte– Contains both positively and negatively charged groups.

Dosage:

The amount of chemical required to perform depends on the type of application and product. The specific dosage rates and method will be specified by the CSL technical representative.

Application:
Organic or inorganic coagulants are used in different types of industries depending on their  feasibility efficiency, economic costs and the desired treatment of the industrial water.  The different kinds of applications of industrial coagulants are listed below.
 
  1. Municipal & Industrial Portable Water treatments
  2. Municipal & Industrial Waste Water treatments
  3. Sewage Water treatments
  4. Separation of slurry in Industrial processes
  5. Sizing in Paper & Pulp Industry
  6. Decolorisation of dyes in Textile Industry
  7. Industrial wastes
  8. Sludge treatment

The Role and Importance of Demulsifiers in Oil and Gas Industry

  Demulsifier helps to extract oil and purify water, which is especially important in crude oil production and wastewater treatment.   It is a substance that separates an emulsion into components and destabilizes water-in-oil emulsions. In Crude production, Water-in-oil emulsions are typically produced, owing to the presence of emulsifying agents such as surfactants, slits, fine solids, drilling mud, clay, water, and other impurities. These impurities are undesirable need to be removed which would otherwise shackle the quality of the crude.   How does It work? Demulsifier consists of two liquids that are not mixed with each other and tiny droplets of one liquid are evenly distributed throughout the volume of the other. This kind of liquid is called dispersion medium, and the droplets are called dispersed phase. During the demulsification process, a demulsifier accumulates on the surface of the droplets and groups them together.   The process of separating a...

What is EDTA? What are the applications of EDTA?

  E DTA or Ethylenediaminetetraacetic acid is a weak acid used as a chelating agent. Ethylenediamine tetra acetic acid contains an amino carboxylic group with the formula C10H16N2O8. It is a versatile chemical compound with a wide range of applications across various industries. EDTA is considered an anthropogenic compound with the ability to sequester various polyvalent cations, use to minimize metal contaminants, and facilitate enzymatic reactions that could be inhibited by heavy metal traces.   How Does EDTA Work? EDTA is a versatile compound with strong chelating properties that grabs metallic cations such as lead or calcium from the process. Its chemical structure contains four carboxylic acid groups and two amine groups, which allow it to form strong bonds with metal ions, preventing them from reacting with other substances, If the bond is weak, other chemicals can break this bond to form their own compounds. EDTA is the most widely used chelating agent for the re...

Replacing Sodium Hypochlorite with Double Chain QAC based Disinfectant

Replacing Sodium Hypochlorite with Double Chain QAC based Disinfectant Remember that pungent smell when mass disinfection of public places occurs. That same irritating smell you can relate to in swimming pools, and your eyes itch and redden, and your skin itches, and there is a big board saying “Chlorine in pool”, that’s hypochlorous acid, viz., when sodium hypochlorite breaks down. Sodium hypochlorite/ Hypo (NaOCl) is inorganic chlorine based liquid disinfectant, available as aqueous solutions of 5.25% - 6.15% (household bleach) or concentrated 12% NaOCl solutions. Large quantities are also used as a disinfectant in water and wastewater treatment and sanitary equipment. In food processing, sodium hypochlorite is used to sanitize food preparation equipment, in fruit and vegetable processing, mushroom production, hog, beef and poultry production, and fish processing. Typical Uses of Hypo: ·       2%: Shock Chlorination of Wells · ...
