Application of spray polyaluminum chloride (Asiafloc) in water treatment

Product Introduction:

Spray type yellow polyaluminium chloride, PAC for short, national standard alumina content of 30%, this product adopts new production technology, spray polyaluminium chloride acidity is lower than other inorganic coagulants. The product is further atomized at the same time of drying to make a tiny powder polyaluminum chloride. Spray polyaluminum chloride is a water-soluble agent with good thermal stability and high solubility.

Production technology of spray yellow polyaluminium chloride is again in the process of high temperature drying, the 40-50% solid content of polyaluminium chloride solution in the introduction of high-pressure pump, through the pressure into the atomizer in the dryer after atomization, dispersed into tiny droplets, droplets after north dry, get solid fine powder products, make dry granulation and completed at the same time. The process flow is:

Liquid raw material → pressure filtration → spray tower spray drying → finished product

Product features:

Coagulation precipitation effect is good, decolorization and turbidity removal effect is good.

2, the appearance of yellow powder particles is very fine, fast dissolution rate, soluble in water, water insoluble matter is very few.

3, alumina content standard, small dosage of reagent.

Product use:

Spray yellow polyaluminum chloride is suitable for drinking water, tap water, groundwater, high pure water, river water, industrial water purification treatment. The suitable PH range is 5.0-9.0, and the best PH value is 6.5-7.6.

Usage:

Users can determine the best dosage according to different water quality and different terrain, through the test of dispensing concentration.

1. Liquid products can be placed directly or diluted. Solid products need to be dissolved and diluted before placing. Determine the dilution amount based on the water quality and product quantity to be treated. The dilution ratio is 2-20% for solid products and 5-50% (depending on weight) for liquid products.

2. The dosage of liquid product is 3-40g/ton, and that of solid product is 1-15g/ton. The specific dosage is subject to flocculation test and experiment.

3. The acidity of yellow spray polyaluminum chloride is lower than that of other inorganic flocculants.

The difference between the production process of spray yellow polyaluminum chloride and ordinary polyaluminum chloride:

Spray drying:

Liquid raw materials ---- pressure filtration ---- spray tower spray drying ---- finished products

General drying:

Liquid raw material ---- place ---- drum to dry ---- finished product

Different synthesis costs:

Yellow spray polyaluminum chloride has high stability, suitable for wide water area, fast hydrolysis speed, strong absorption, fast flocculation formation, low turbidity, and super dehydrating. For the same water quality, spray type yellow polyaluminum chloride is relatively small compared with other products, especially for high pollution water quality, spray type yellow polyaluminum chloride only needs half of the drum drying product dosage, which not only reduces labor intensity, but also reduces the cost of customers. In addition, too much spray drying products will not cause pollution, can avoid accidents, to ensure the quality of drinking water safety.

Product packaging and storage:

1, product packaging unified 25kg/bag, plastic moisture-proof film, woven bag double packaging. Chinese neutral packaging, English neutral packaging two kinds, according to customer demand can also provide packaging label.

2. The storage period of solid polyaluminum chloride products is two years. It should be placed in a ventilated and dry place to avoid exposure to wind and sun.
