Compared with other coagulants, PAC water treatment agent has the following advantages. A wide range of applications, and a wide range of adaptable water. It is easy to quickly form large alum flowers and has good precipitation performance. The suitable PH value range is wide (between 5-9), and the PH value and alkalinity of the water after treatment have a small drop. When the water temperature is low, the stable precipitation effect can still be maintained. The degree of alkalinity is higher than other aluminum salts and iron salts, and it has less erosion effect on equipment. It is a kind of inorganic polymer coagulant. Mainly through the compression bilevel, adsorption electric neutralization, adsorption bridge, precipitation nets and other mechanisms, so that the water fine suspended particles and colloidal ions destabilization, aggregation, flocculation, coagulation, precipitation, to achieve the purification treatment effect.
What Is A Flocculant
Flocculants are chemicals used to remove or reduce turbidity or suspended solids in water and accelerate the sedimentation speed of impurities and sludge in water. The earliest application was inorganic flocculants, such as alum and ferric chloride. Organic and polymer flocculants are flocculants widely used in water supply and wastewater treatment in the future. Can be divided into anionic flocculants, such as carboxymethyl cellulose, sodium polyacrylate and so on. Cationic flocculant, such as polyvinylamine, etc. There are also non-ionic flocculants, such as polyacrylamide. Their flocculation is mainly achieved through charge neutralization and adsorption bridging.
Physical and chemical properties of polyaluminum chloride
The liquid product is a colorless, light yellow, light gray or brown transparent or translucent liquid without precipitation. The solid product is white, light gray, light yellow or brown grains or powder. The content of alumina in the product: liquid product> 8%, solid product 20%-40%, alkalinity 70%-75%.
Application And Usage Method
PAC is an important coagulant in the field of water purification. It has a high-efficiency purification effect on low temperature, low turbidity and high turbidity water. However, since its monomer and organic matter react to produce substances that are harmful to human health, it is important to ensure its purity in water purification. Would like to know more about PAC and other water treatment agents? Fengbai Industrial Company, a professional manufacturer of this kind of chemicals can give you help.
Add the product (solid) and room temperature water at a weight ratio of 1/3 while stirring. After it is completely dissolved, add water to dilute to the required concentration. When the original water concentration is 100~500mg/, the dosage is 3~6mg/ 1. For specific dosing, a water test should be conducted according to the water quality, and the best dosing amount should be selected before use.
Safety And Protection
Water treatment agent polyaluminum chloride products are corrosive, if accidentally splashed on the skin, immediately rinse with water. The personnel who produce and use this product must wear work clothes, masks, gloves, and rubber boots. The production equipment should be sealed, and the workshop should have good ventilation. Water treatment agent polyaluminum chloride products have no risk of combustion and explosion.
