Product Introduction

This product is a new type of highly efficient inorganic coagulant, also known as polyaluminum chloride, abbreviated as polyaluminum, with the English abbreviation PAC (poly aluminum chloride). It is a water-soluble inorganic polymer between AlCI3 and Al(OH)3. This product is made from synthetic hydrochloric acid, calcium aluminate powder, and bauxite using advanced technology. It has good flocculation effects and a low Price. Its purification effect is superior to traditional inorganic salt coagulants such as aluminum sulfate and iron salts. The solid product uses spray drying technology and drum drying technology. The products are available in industrial-grade yellow powder and drum-dried granular form. The product is widely used in industrial wastewater, drinking water, municipal water supply, and industrial water purification.

Advantages of Guangrui Drum-dried Polyaluminum Chloride

1. Drum-dried polyaluminum chloride, Al ₂ O ₃ content is uniform and stable, and is easily controlled within the specified range. It enhances the adsorption capacity of colloidal particles, achieving both coagulation and flocculation effects, which cannot be achieved by other drying methods.
2. Due to the use of plate and frame filter press technology, the water insolubles in the solid are below 0.3, and the water insolubles in the liquid are below 0.1. This ensures smooth user pipelines and improves drug utilization, which cannot be achieved by natural sedimentation.

Usage

Dissolve the solid product with water at a ratio of 1:3, then dilute it with 10-30 times the amount of water to the required concentration before use. The optimal PH value for addition is 6.5-8.0. Selecting the optimal PH value for addition can maximize the coagulation effect. The dosage can be determined based on the different turbidity of the raw water to determine the optimal dosage. Generally, when the raw water turbidity is 100-500mg/L, the dosage per thousand tons is 10-20kg. When the raw water turbidity is high, the dosage should be increased appropriately; when the turbidity is low, the dosage can be reduced appropriately. For rural use, the agent can be added to a water tank, stirred evenly, allowed to stand, and the supernatant can be used. Add about 1 gram of this agent per 50 kg. If this agent is used in combination with the polyacrylamide produced by our company, the effect will be even better. For dosing, Guangrui brand anionic polyacrylamide or cationic polyacrylamide can be dissolved together with polyaluminum chloride PAC to form a composite flocculant, or PAC can be added to the water to be treated to form aggregates, and then Guangrui brand anionic polyacrylamide can be added to adsorb and bridge to form large flocculants.

Dosage of Polyaluminum Chloride in Different Water Qualities

1. In low-turbidity water, dilute the solid polyaluminum chloride product with tap water at a ratio of 1:3 (weight ratio) and stir until completely dissolved.
2. In domestic and industrial wastewater, refer to adding about 30g of polyaluminum chloride product per ton of wastewater first. Then add the diluted polyacrylamide product (if the effect is not obvious, please adjust the amount of product added accordingly).
3. In paper mill wastewater treatment, use the dosage ratio for low-turbidity water. If the effect is not obvious, it can be added in appropriate amounts.
4. When the raw water turbidity is 100-500mg/L, the dosage is 5-10mg, that is, 5-10kg per thousand tons of water. Before use, it is best to conduct a small test according to the water quality characteristics to select the optimal value, and then use it.
