Poly Aluminium Chloride
Poly Aluminium Chloride (PAC) is most commonly used in the water treatment industry as a coagulant. It is characterised by the degree of basification – the higher this number the higher the polymer content which equals a more efficient product in the clarification of water products.
Other uses of PAC include within the oil and gas industries for oil refining where the product works as an oil-water emulsion destabiliser offering excellent separation performance. In terms of crude oil, any water presence equals a reduced commercial value and higher refining costs, so this product is essential in ensuring optimum efficiency.
PAC is also used in the production of deodorants and anti-perspirant products as the active ingredients that essentially creates a barrier on the skin and helps to reduce levels of sweat. In the paper and pulp industries It is used as a coagulant in papermill wastewater.
1.Cleaning up water at high speed efficiently. Cleaning up water from dirty river and wastewater efficiently.
2.Collecting coal particles from water derived from kaolin laundry sports and coal for the ceramic industry .
3.Mining industry, pharmacy, oil and heavy metals, leather industry, hotel/apartment, textiles etc.
4.Cleaning up drinking water and domestic waste water and oil separation processes in the oil spill industry.
The raw materials of brown polyaluminium chloride are calcium aluminate powder, hydrochloric acid, bauxite and iron powder. The production process adopts the drum drying method, which is generally used for sewage treatment. Because iron powder is added inside, the color is brown. The more iron powder is added, the darker the color is. If the amount of iron powder exceeds a certain amount, it is also called polyaluminium ferric chloride at some times, which has excellent effect in sewage treatment.
The white polyaluminum chloride is called high purity iron free white polyaluminum chloride, or food grade white polyaluminum chloride. Compared with other polyaluminum chloride, it is the highest quality product. The main raw materials are high-quality aluminum hydroxide powder and hydrochloric acid. The production process adopted is the spray drying method, which is the first advanced technology in China. White polyaluminum chloride is used in many fields, such as paper sizing agent, sugar decolorization clarifier, tanning, medicine, cosmetics, precision casting and water treatment.
The raw materials of yellow polyaluminum chloride are calcium aluminate powder, hydrochloric acid and bauxite, which are mainly used for sewage treatment and drinking water treatment. The raw materials for drinking water treatment are aluminum hydroxide powder, hydrochloric acid, and a little calcium aluminate powder. The process adopted is the plate and frame filter pressing process or spray drying process. For the treatment of drinking water, the country has strict requirements on heavy metals, so both raw materials and production process are better than brown polyaluminum chloride. There are two solid forms: flake and powder.
The Benefits of Using PAC
How does PAC water treatment work?
Poly Aluminium Chloride is a highly efficient water treatment chemical where it works as a coagulant to extract and clump together contaminants, colloidal and suspended matter. This results in the formation of floc (flocculation) for removal via filters. The below image showing coagulation in action illustrates this process.
Poly Aluminium Chloride products for use in water treatment are typically characterised by their level of basification (%). Basification is the concentration of hydroxyl groups relative to aluminium ions. The higher the basicity, the lower the aluminium content and therefore the higher performance regarding contaminant removal. This lower rate of aluminium also benefits the process where aluminium residuals are greatly reduced.
1.Q: Are you a trading company or a water treatment manufacturer?
A: We are a manufacturer with 9 years experiences in chemicals industry. And we have many true case to support us to provide the best effect for kinds of water.
2.Q:How can I know whether your performance is better?
A: My friend, the best way to check whether the performance is good or not good is to get some samples to test.
3.Q:How to use Poly Aluminium Chloride?
A:Solid products need to be dissolved and diluted before being put into use. Users can determine the optimal dosage by mixing the reagent concentration through test according to different water quality.
① Solid products are 2-20%.
② The volume of solid products is 1-15 g/ton,
The specific dosage is subject to flocculation test and experiment.
4.Q:What's your delivery time?
A: Usually we will arrange the shipment in 7 -15 days.
I’m glad to meet WIT-STONE, who is really an excellent chemical supplier. Cooperation needs to continue, and trust is built little by little. They have a strict quality control system, which I highly appreciate
After selecting suppliers for many times, we resolutely chose WIT-STONE. Integrity, enthusiasm and professionalism have captured our trust again and again
I am a factory from the United States. I will order a lot of Poly ferric sulfate to manage waste water . WIT-STONE's service is warm, the quality is consistent, and it is the best choice.
