Polyaluminium Chloride (PAC) stands as a cornerstone in modern water treatment, prized for its potent coagulant properties. As a leading manufacturer and supplier of this vital chemical, we often guide our clients on its optimal application and storage to ensure maximum efficacy and safety. This article delves into the practical aspects of using and storing PAC, offering valuable insights for procurement managers and R&D scientists in the water treatment sector.

Understanding the Versatility of PAC in Water Treatment

PAC is an inorganic polymer coagulant renowned for its ability to remove suspended solids, clarify water, and eliminate color and odor. Its efficacy extends across a broad spectrum of water sources, from municipal drinking water to challenging industrial wastewater streams. For procurement managers looking to buy Polyaluminium Chloride for wastewater treatment, understanding its diverse applications is key. It plays a critical role in purifying everything from urban sewage to industrial effluents from the printing and dyeing industry, and even finds utility in sectors like papermaking, leather production, and petroleum refining.

Effective Usage Strategies for PAC Powder

When considering how to use Polyaluminium Chloride powder, two primary methods are employed. The first involves direct addition of the solid product to the water body needing treatment. This method requires precise dosing, typically determined through jar testing to ascertain the optimal concentration for specific water conditions. The second, often yielding superior results, is to prepare a solution. This usually involves dissolving the PAC in water, preferably heated, with continuous stirring until fully dissolved. It is crucial that this prepared solution is used within 24 hours to maintain its effectiveness. For those inquiring about the PAC water treatment price, investing in a well-prepared solution can often lead to more efficient contaminant removal and better overall results.

Crucial Considerations for Optimal Coagulation

To maximize the benefits of PAC, several factors must be carefully managed. Jar testing is indispensable for determining the precise dosage and type of PAC required, especially when dealing with unknown water compositions. pH control is paramount; PAC functions best within a specific pH range. Acidic or alkaline wastewater may require pre-adjustment using alkaline or acidic substances, respectively, to unlock PAC's full coagulation potential. Proper mixing and stirring are also vital. Mechanical stirring or aeration for 1-3 minutes at a speed of 10-35 r/min ensures thorough contact between PAC and contaminants, promoting the formation of larger, more easily settled flocs. Finally, water temperature influences coagulation speed and effectiveness, with warmer temperatures generally enhancing the process.

Best Practices for Storing Polyaluminium Chloride

Proper storage is essential to preserve the quality and performance of Polyaluminium Chloride. As a manufacturer, we emphasize the importance of sealed storage in a dry, cool, and well-ventilated area to prevent moisture absorption and oxidation. Keep containers tightly sealed and away from incompatible substances. Moisture-proofing and anti-caking are critical; PAC can clump after prolonged storage, impacting its usability. Avoid direct contact with the ground and use moisture-proof barriers. Regular checks for agglomeration are recommended. Furthermore, it's vital to keep PAC away from heat and direct sunlight, as these can cause clumping and degrade product performance. Adhering to safety regulations during storage, including wearing appropriate protective gear, is also a non-negotiable aspect of handling this chemical.
