Product details
Hangzhou Asia-Pacific Chemical Equipment Co., Ltd. provides one-stop EPC engineering solutions for chlorine downstream chemical plants: Polyaluminum chloride (PAC) Plant.
The production scale can be customized and designed according to local market needs. The business scope includes process engineering design, equipment manufacturing, on-site supervision, commissioning and personnel training, delivering complete plants that can be put into direct operation for chemical projects in Africa, the Middle East and Southeast Asia.
Poly aluminum chloride (PAC), also known as basic aluminum chloride, is an inorganic polymer water treatment agent with the most mature technology and the largest sales volume. We provide customers with Poly aluminum chloride production solutions, It is widely used in the treatment of domestic sewage, industrial wastewater and sludge. Moreover, it is easy to store, has no "three causing" effect, and the synthetic conditions are not as harsh as those of organic polymers. It has the advantages of good coagulation efficiency, large flocculation volume, easy storage, low dosage, high efficiency, fast sedimentation, wide application range and so on.
Features: poly aluminium chloride manufacturing process uses calcium aluminate powder and hydrochloric acid as raw materials. Hydrochloric acid and calcium aluminate are added into the batching tank in proportion for batching, and the slurry is pumped to the reactor. The materials react in the reactor to produce liquid PAC, and then the filtrate enters the finished product tank after sedimentation and filtration. The liquid is pumped into the physicochemical tray at the top of the drying tower, and the droplets flow down with the hot air to dry into powdery PAC. After the finished powder is discharged from the drying tower, it is cooled by the air lift pipe and separated by the cyclone separator and falls into the finished product silo for packaging. The dry tail gas and finished product cooling air are discharged after being dedusted by their respective cyclone dust removers and then sprayed and washed.
FAQ：
Q：What raw materials are required for the PAC production line?
A：Main raw materials are hydrochloric acid, aluminum hydroxide /bauxite. Our design can adapt to local‑available raw‑material resources for your plant。
Q：Can your plant produce both liquid PAC and spray‑dried powder PAC?
A：Yes. Our turnkey PAC line supports liquid PAC, and optional spray‑drying unit to make high‑quality powder PAC for drinking‑water grade。
Q：What is your scope of supply for the PAC turnkey project?
A：Process design, core equipment manufacturing, layout drawing, overseas guidance for installation, commissioning and operator full‑training service.
Q：Can you customize different production capacity for PAC plant?
A：Sure. We customize capacity from small‑scale to large‑size PAC plant according to customer’s local market demand and budget.
Q：How long is the general project cycle for a PAC production plant?
A：Equipment manufacturing period about 3‑5 months; on‑site installation & commissioning takes 2‑4 months, subject to site preparation progress by client side.
