Swimming pool water purifying agent belongs to the commonly used medicaments in swimming pool water treatment. Polyaluminium Chloride (PAC) is a new type of high-efficiency inorganic polymer flocculant, which is very strong in suspension in water. Adsorption, the purpose of condensing suspended solids in water.
What is the swimming pool water purifying agent? Classification and use of water purifying agents
Swimming pool water purifying agent is a commonly used agent in swimming pool water treatment. It is also collectively called precipitant, flocculant. Its main component is polyaluminium chloride. It is very turbid due to suspended water, algae and other impurities. Significant purification.
The swimming pool water purifying agent commonly used in the classification of swimming pool water purifying agents includes polyaluminum chloride, polyaluminum ferric chloride, basic aluminum chloride, polyacrylamide, ferrous sulfate, aluminum sulfate, and polyferric sulfate. The following focuses on the definition and use of polyaluminum chloride:
What is polyaluminium chloride?
Polyaluminium Chloride (PAC). Also commonly referred to as basic aluminum chloride or coagulant, it is a water-soluble inorganic high molecular polymer between ALCL3 and AL(OH)3. The chemical formula is [AL2(OH)NCL6- NLm] where m represents the degree of polymerization and n represents the neutrality of the PAC product. The color is yellow or light yellow, dark brown, dark gray resinous solid. The product has strong bridging properties, and is accompanied by physical and chemical processes such as coagulation, adsorption and precipitation during the hydrolysis process. Physicochemical properties: the name polyaluminum, polyaluminum, molecular formula [Al2(OH)nCl6-n.XH2O]m or [Al2(OH)nCl6-n]m, (m≤10; n≤5), is a kind A new type of high-efficiency inorganic polymer flocculant whose aqueous solution is a hydrolyzed product between aluminum trichloride and aluminum hydroxide, which has a colloidal charge, so it has strong adsorption to suspended solids in water, thereby achieving suspension in condensed water. The purpose of the object.
How to use polyaluminium chloride:
1. When using, first make a small test according to the water quality, and choose the best point for the clean water effect and the small amount of the small amount. The solution should be used with the solution, and the non-potable water should be selected according to the actual situation.
2. When using solids, first add water to dissolve the solution into 10-25%, then dilute the water to the desired concentration. When dissolving, first add water and slowly feed, and continue to stir.
3, different manufacturers or different brands of water treatment agents can not be mixed, and must not be mixed with other chemicals.
4. The stock solution and diluent are slightly corrosive, but lower than other inorganic flocculants.
5, the product effective storage period: liquid for six months, solid two years. Solid products can still be used after the tide.
6, the product is properly added, the water quality after purification meets the sanitary standard of drinking water.

PPFD is a key factor in the detection of Plant Growth Light. Optical quantum flux density (PPFD) refers to the luminous flux density in photosynthetically active radiation. Most Plant Growing Lamp on the market that can achieve an average PPFD of 2000 μmol/m²/s have a power of 600W, while Litehome's Plant Light just only need 200W. Can greatly reduce your electricity bills.
With lower production costs, your products will have more advantages. This is why you should choose litehomeLED Plant Grow Light.
