PAC chemical dosing system. PAC(flocculant) is mainly used to purify drinking water. It is also used for special water treatment, iron removal, cadmium removal, fluorine removal, radioactive pollution, and oil slick, industrial wastewater treatment, printing, dyeing wastewater, casting, paper making, medicine, and leather making, etc.
1. Product specification:
Polyaluminium chloride is abbreviated as PAC. Also commonly known as water purifying agents or coagulants, it is a polynuclear, multinuclear complex cationic inorganic polymer flocculant. The solid product looks yellow powder and is easily soluble in water. Bridge adsorption, color yellow or light yellow solid PAC. Also commonly known as water purifying agents or coagulants, it is a polynuclear, multinuclear complex cationic inorganic polymer flocculant. The solid product looks yellow powder and is easily soluble in water. The bridge is adsorptive and has a yellow or light yellow solid color. The product has strong bridging performance, and it is accompanied by physical and chemical processes such as coagulation, adsorption and precipitation during the hydrolysis process.
2. Product Category:
According to the different production processes of the product (1) drum drying type polyaluminum chloride (3) spray drying type polyaluminium chloride · drum drying polyaluminum chloride is further divided into: (1) natural precipitation type polyaluminum chloride - - As the name suggests, natural precipitation is used in primary and secondary sedimentation tanks without human factors. (2) Plate frame pressure filter type polyaluminium chloride - This process is filtered by a plate and frame filter press, so that the produced polyaluminum chloride indexes are superior to the natural precipitation type. · Spray-drying polyaluminum chloride is mainly determined by the working principle of a pressure atomizer, which makes this drying system have its own characteristics. Since the product obtained by pressure spray drying is porous or hollow fine particles, the pressure-type spray drying is used for the purpose of obtaining a granular product, and the obtained granular product has excellent dustproof performance and flowability. Due to the large contact area between the product and the water, the wetting performance is better than that of the powdered product, the speed of purifying water is significantly higher than that of the powdery product, and the pressure spray-dried products have unique characteristics.
3. Properties of polyaluminum chloride:
a. The water quality after purification with polyaluminum chloride is better than that of aluminum sulfate coagulant, and the clean water cost is 15-30% lower than that.
b. The formation of floc is fast, the sedimentation speed is fast, and the processing capacity of traditional products such as aluminum sulfate is large.
c. The alkalinity in the consumed water is lower than that of various inorganic coagulants, so that the alkali agent can be administered without or with little.
d, the adapted source water PH5.0-9.0 range can be agglomerated.
e, low corrosivity and good operating conditions.
f, solubility is better than aluminum sulfate.
g, the increase of salt in the treated water is small, which is beneficial to ion exchange treatment and high purity water production.
h. Adaptability to source water temperature is superior to inorganic coagulant such as aluminum sulfate.
4. Use of polyaluminum chloride:
The product can be used for sterilization, deodorization, defluoridation, aluminum, chromium, degreasing, turbidity removal, heavy metal salts, radioactive contaminants, and a wide range of applications in purifying various water sources.
a, purification of drinking water, domestic sewage.
b. Purification of industrial water, industrial wastewater, mines, oilfield refilling, purification of water, metallurgy, coal washing, leather and various chemical wastewater treatment.
c. Industrial production applications; paper sizing, printing and dyeing bleaching, cement quick-setting agent, precision casting hardener, refractory adhesive, glycerin refining, cloth anti-wrinkle, medicine, cosmetics and other industries, wastewater can be recycled.
d. In the refining industry, it is used for separation without water, and the effect is very good.
