Poly Aluminum Chloride (PAC)

Chemtex Speciality Limited is one of the leading international ISO 9001:2008 certified companies dedicated to provide its clients with leading edge technology in RO membrane pretreatment chemicals to treat RO feed water from scaling, corrosion, organic foulants like bacteria, fungi, algae and inorganic coagulants like PAC (powder & liquid)etc.

Aluminum Chlorohydrate is a group of specific aluminum salts having the general formula Al2Cl(OH)5 AlnCl(3n-m)(OH)m. It is used in deodorants and antiperspirants and as coagulant in water purification.

In water purification, this compound is preferred in some cases because of its’ high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminum salts such as aluminum sulfate, aluminum chloride and various forms of poly aluminum chloride and poly aluminum chlorisulfate, in which the aluminum structure results in a lower net charge than aluminum chlorohydrate. Further, the high degree of neutralization of the HCl results in minimal impact on treated water pH, when compared to other aluminum and iron salts. It is known in names of Aluminum Hydroxychloride, Aluminum Chlorhydroxide, Aluminum Chloride, basic, Aluminum Chlorohydrol and Poly Aluminum Chloride (PAC) etc.

Chemtex’s Poly Aluminum Chloride (PAC) is premium quality product manufactured by state of the art technologies.

Equivalent or even better than CHARGEPAC range of products from CHEMBOND ASHLAND etc.

Application: – Water Treatment, Waste water treatment, effluent water treatment, RO water pre-treatment

Specification:- 
Properties: Typical Value
Form & Appearance: Powder/Liquid
Odor: Characteristic
Specific Gravity: Product Specific
pH (Neat): Product Specific
Solubility in Water: 100%

Dosage and Method: – Chemtex’s Poly Aluminum Chloride (PAC) is dosed at the time of pretreatment of RO feed water.

It is dosed exactly as per the dosage rate and method of CHARGEPAC range of products from CHEMBOND ASHLAND etc.

Key Features and Major Benefits:-

A) Municipal and Industrial Water Treatment :
Polyaluminum Chloride Solution is often employed as the primary coagulant in potable water and industrial water treatment plants, replacing the need for other coagulants such as alum, and in many cases also eliminating or at least greatly reducing the need for pH adjustment chemicals, coagulant aids and filter aids. Consistently recognized benefits of converting to a Polyaluminum Chloride are:

  1. Improved turbidity removal
  2. Improved color removal
  3. Increased TOC (Total Organic Carbon) removal
  4. Lower filter turbidities
  5. Increased filter run length
  6. Sludge reduction of 25-75%
  7. Simplified operations by eliminating pH and secondary polyelectrolyte feed
  8. Lower overall treatment costs

B) Municipal and Industrial Wastewater Treatment :
Polyaluminum Chloride Solution is also used in wastewater treatment applications for:

  1. TSS (Total Suspended Solids) removal
  2. Phosphate removal
  3. COD (Chemical Oxygen Demand) reduction in industrial wastewater treatment
  4. BOD (Biological Oxygen Demand) and TOC (Total Organic Carbon) removal in municipal wastewater treatment.

C) Pulp and Paper – On Machine :
Polyaluminum Chloride Solution is used extensively in several on machine applications as a:

  1. Size bonding agent
  2. Anionic trash scavenger
  3. Retention and drainage aid
  4. Pitch and stickies control additive

D) Separation of slurry in Industrial processes
E) Decontamination of dyes in Textile Industries
F) Sewage Water treatments

RO Coagulants or Cationic Polyelectrolyte

Chemtex Speciality Limited is one of the leading international ISO 9001:2008 certified companies dedicated to provide its clients with leading edge technology in RO membrane pretreatment chemicals to treat RO feed water from scaling, corrosion, organic foulants like bacteria, fungi, algae etc.

Chemtex’s R&D Team is continuously involved to meet the ever changing requirements of the RO membrane water treatment industry. As a result, Chemtex has repeatedly produced and is still producing superior quality and very effective RO pretreatment chemicals to run your RO systems smoothly and to enhance the system life.

 

Coming to fresh water and wastewater clarification, products that utilize a single type of coagulant chemistry typically do not provide exceptional results. Unlike single-component products, Chemtex’s RO Coagulants (Cationic Polyelectrolyte) comprise a family of products that typically utilize two or more chemistries to specifically improve the clarification of fresh water and wastewater over a wide range of conditions.

Coagulants from Chemtex can increase pre-filtration efficiency and productivity in membrane systems for RO feed water.

  • Improve liquids/solids separation
  • Are compatible with all RO and thin-film composite membranes
  • Assure consistent SDI feed water specifications set by membrane manufacturers
  • Increase resistance to filter breakthrough compared to metal coagulants
  • Provide better color removal than organic polymers
  • Are effective over a broad pH range
  • Minimize flushing time and backwash waste
  • Reduce treatment costs

It is a highly effective quaternary polymer compound which is used for color removal in textile, paper and dyeing industries and light color liquid from other industries.

Equivalent or even better than MAXFLOC T, MAXFLOC 20, MAXFLOC 30, MAXFLOC 502, MAXFLOC 504, MAXFLOC 506, MAXFLOC 507, MAXFLOC C-11, MAXFLOC C-21, MAXFLOC C-22, MAXFLOC C-31 and MAXFLOC C-33 from THERMAX; PERMAFLOC PC 306, PERMAFLOC PC 306 T and PERMAFLOC PC 603 T from NALCO; CHARGEPAC and AMERFLOC range of products from CHEMBOND ASHLAND; SOILSEP range of products from GE WATER etc.

Specification:-

  • Form & Appearance:      Powder/Liquid
  • Viscosity:             Product Specific (mPa.s)
  • Specific Gravity:                                Product Specific
  • pH:         Product Specific (pH)
  • Solid Content:                   Product Specific (in %)
  • Charge:                                Cationic
  • Solubility in Water:          100%

Application: – Water Treatment, Waste water treatment, effluent water treatment, RO water pre-treatment, Wastewater

 

Dosage and Method: – Chemtex’s RO Coagulants (Cationic Polyelectrolyte) are dosed during water pretreatment for solid/liquid separation before the water gets introduced to softner/reverse osmosis system. Coagulating chemical is diluting it with 10 – 40 times with water and then dosed into the waste water directly, after being mixed several minutes, waste is precipitated or air – floated and the water becomes clear.

It is dosed exactly as per the dosage rate and method of MAXFLOC T, MAXFLOC 20, MAXFLOC 30, MAXFLOC 502, MAXFLOC 504, MAXFLOC 506, MAXFLOC 507, MAXFLOC C-11, MAXFLOC C-21, MAXFLOC C-22, MAXFLOC C-31 and MAXFLOC C-33 from THERMAX; PERMAFLOC PC 306, PERMAFLOC PC 306 T and PERMAFLOC PC 603 T from NALCO; CHARGEPAC and AMERFLOC range of products from CHEMBOND ASHLAND; SOILSEP range of products from GE WATER etc.
