To use
Widely used in domestic sewage, industrial water, all kinds of industrial wastewater, urban sewage and sludge dehydration purification treatment, suitable for river heavy metal pollution, water plant water, steel coking wastewater, manganese wastewater, mining and metallurgical wastewater, circuit board wastewater, electroplating wastewater, urban sewage flocculation purification treatment.
Performance characteristics
This product is a kind of high quality, high efficiency inorganic aluminum flocculant, compared with other inorganic flocculant has the following advantages:
(1) Excellent coagulation performance, dense alum, fast settlement speed: 5-30 minutes settlement is complete, with auxiliary settlement facilities, the settlement speed is faster.
② The water purification effect is good, the water quality is good, does not contain iron, fluorine, nitrite and heavy metal ions and other harmful substances.
③ It has significant decolorization, deodorization, deoiling, bacterialization, removal of heavy metal ions, ammonia nitrogen, nitrite nitrogen, silica sol, radioactive substances and carcinogens in wastewater, and the removal rate of COD, BOD and chroma is as high as 90%.
(4) Safe and reliable, non-toxic and harmless, suitable for a wide range of water PH value 4-11, the best PH range in 6-9, after purification of raw water PH and total alkalinity change range is small, small corrosion of water treatment equipment, and can reduce the hardness of water.
(5) Good purification effect on algal, low temperature and low turbidity raw water, and better purification effect on high turbidity raw water.
⑥ Stable performance, long storage period, no precipitation, no deterioration. The user is convenient, the dosage is small, the cost is low, the processing cost can save 20-60%.

Use method and precautions
According to the different properties of raw water, field debugging or beaker test is conducted to determine the best use conditions and dosage to achieve the best purification treatment effect.
1, strengthen filtration, mainly the reasonable selection of filter layer structure and filter aid, in order to improve the removal rate of filter mud, it is an important measure to improve water quality.
2, this product is used in the treatment of industrial wastewater, the use of the method is basically the same as the water plant, for high chroma, high COD, BOD raw water purification treatment, adding the appropriate additives used together, the effect is better.
3, the use of chemical coagulation treatment of sewage customers, the original sewage treatment equipment does not need to do large investment transformation, only need to increase the storage pool or high metering tank can use this product.
Packaging and storage
1. For customers with short distance, they can be transported by liquid tank truck and unloaded into anticorrosive tank or container for storage with a storage period of 6 months.
2.the distance of the customer, with plastic bucket dressed in 50KG per barrel (according to user needs customized weight specification Packaging).
3. During the transportation and storage of the product, it shall avoid detonation, and the storage temperature shall not be lower than -5℃.
