PRODUCTS

• PH Correction – Acid (Sulphuric Acid)
• Disinfection Solution (Sodium Hypochlorite)
• Quick Flocculant (PAC,PAM)
• Liquid Polymer
• Reverse Osmosis Antiscalants

   PAM   

PAM is also known as PolyAcrylamide, is a kind of high molecular polymer, white powder, divided into anion-cation type and non-ionic type.

The cationic type is used to dewater the excess sludge produced by the sewage plant, so as to make the sludge floc more cohesive and the sludge dewatering efficiency is high

The anionic type is mainly used for coagulation and sedimentation. When the suspended solids in water are high and not easy to settle, some anionic flocculants are added to achieve good sedimentation effect.

APPLICATION

• It is used as retention aid and reinforcing agent in paper making process.
• It is used as coagulant aid, flocculant and sludge dehydrating agent in water treatment.
• It is used as precipitation agent and oil displacement agent in oil drilling and production.
• PAM is also widely used in thickening, stabilizing colloid, drag reduction, bonding, film forming, biomedical materials, etc.

FEATURE

• Easy to dissolve.
• High efficiency.
• High molecular.
• High purity, without impurity.

   PAC   

PAC is also called PolyAluminum Chloride. It is yellow powder and also a flocculant. Its role in water is to strengthen the cohesiveness of activated sludge and to remove COD. When the influent COD is too high to be treated, adding proper amount of polyaluminum can ensure that the effluent reaches the standard to a certain extent

APPLICATION

• Purifying drinking water, sewage.
• Industrial water purification, industrial wastewater, mining, oil field injection water, metallurgy, coal washing, leather and all kinds of chemical waste water treatment.
• Industrial production: Paper sizing, dye printing, bleaching and dyeing, medicine and other industries.
• In artificial coal industry, it is used for separating coal and water with excellent effect. In the oil refining industry, for oil and water separation.

FEATURE

• Its dosage lower than aluminum sulfate (based on Al2O3) and water treatment cost is lower than other inorganic flocculants.
• The product can cause quick formation of flocs, big flocs formation and rapid precipitation. Its treatment capacity is 1.3-3.0 times of other inorganic flocculants.
• It enjoys wide-range adaptability for different-temperature source water and a good solubility.
• It is slightly corrosive and easy for operation.
• The liquid product is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage
