Advantage
Its purifying effect on low-temperature, low-turbidity and heavily organic-polluted raw water is much better than other organic flocculants , furthermore, the treatment cost is lowered by 20%-80%.
01
It can lead to quick formation of flocculants (especially at low temperature) with big size and rapid precipitation service life of cellular filter of sedimentation basin.
02
It can adapt to a wide range of pH value (5−9), and can reduce the pH value and basicity after processing.
03
The dosage is smaller than that of other flocculants.It has wide adaptability to the waters at different temperatures and different regions.
04
Higher basicity, lower corrosion, easy for operation,and long-term use of non-occlusion.
05
Chemical Properties
Polyaluminum chloride (PAC) is white, light gray, light yellow or brown crystals or powders. The color varies with the production process and raw materials. It is slightly acidic. After dilution with water, aluminum hydroxide precipitates. In the hydrolysis process, physical and chemical processes such as electrochemistry, coagulation, adsorption and precipitation are accompanied, so as to achieve the purpose of water purification.
Packing & Delivery
In two-layer bag with the interior in plastic bag and the exterior in woven. The net weight of each bag is 25kg.
The product shall be sealed and stored in the dry and ventilated place to prevent from rain, high temperature and strong sunlight.
Different grades of Poly Aluminium Chloride
Recommends a normal dosing rate of 0.1ml/m3 of the total flow rate, which it has also described as 0.005ml/m3 as aluminium.
There are now a number of different grades of pac with aluminium concentrations between 9.5% and 18%. The concentration of aluminium is not the only consideration when selecting a grade of pac to use.
Poly aluminium chloride products are characterised by their degree of basification i.E. The concentration of hydroxyl groups (oh) relative to aluminium ions.
Poly aluminium chloride products can be in the range of 5%-65% basicity. As a general rule, the higher the basicity, the higher the polymer content and thus cationic charge density and efficiency. Higher basicity products have a lower aluminium content but are more efficient in clarification of water (i.E. Turbidity/suspended solids removal).
Because there is less aluminium content there is less aluminium in the backwash water. Furthermore, aluminium residuals are minimised. The lower aluminium content products have a higher basicity, so the best advice that can give is to use the same dosing rate for all grades of poly aluminium chloride, that is 0.1ml/m3 of the total flow rate.
Application
Polyaluminium chloride is a kind of inorganic macromolecule flocculant. Through the hydroxyl ion bridging function and the polyvalent anion polymeric function, it produces large molecular and high electricity inorganic macromolecule. It adopts a wide PH range of 5.0~9.0, and the best is between 6.5~7.6.
