Issues to Be Aware of When Using Anionic Polyacrylamide

Corrosion-resistant and well-stirred dissolution equipment should be selected, such as stainless steel mixing tanks. Avoid usingiron containers as iron ions may react with anionic polyacrylamide, affecting product performance.

Use dean tap water or deionized water, avoiding water sources with large impurities. The water temperature should generalybe controlled between 20 - 30°C. Excessively high or low temperatures can affect the dissolution rate and effect.

Control the disolution ratio of anionic polyacrylamide according to the product manual. Generally, the dissolution ratio is 0.1%-0.3%. A concentration too high may lead to dissolution difficuties and micelle formation, while too low a concentration mayaffect the usage effect.

During the dissolution process, an appropriate stirring speed and time should be used. The stirring speed should not be too fastto avoid damaging the polymer molecular chain The usual stirring time is 40 - 60 minutes to ensure the polymer is fullydissolved

Select a suitable addition point based on the treatment process and water quality conditions. Generally, anionic polyacrylamidecan be added at locations such as reaction tanks and sedimentation tanks. The addition point should be as close to the mixingarea as possible so that the polymer can fully contact suspended matters and colloids in the water.

Precisely controlling the amount of anionic polyacrylamide added is key to ensuring treatment effects. Too little addition cannotachieve the expected flocculation effect, while too much addition may increase sludge volume and treatment costs. The optimaladdition amount can be determined through small tests and pilot tests.

When used in combination with other agents, attention should be paid to the addition sequence. Generaly, inorganiccoagulants such as polyaluminum chloride and aluminum sulfate should be added first, followed by anionic polyacrylamide. Thiscan fully exert the rapid coagulation effect of inorganic coagulants and the adsorption and bridging effect of anionicpolyacrylamide, improving the treatment effect.

Anionic polyacrylamide should be stored in a dry, ventilated, and cool place, avoiding direct sunlight and high temperatureenvironments. The storage temperature should generally be controlled between 5 - 30°C. Also, avoid mixing with other chemicalreagents to prevent reactions that may affect product performance.

The product should use well-sealed packaging materials, such as plastic bags and plastic barrels. The packaging materials shouldhave certain strength and moisture-proof performance to prevent the product from being dampened or damaged during storage and transportation.

During transportation, prevent the product from being squeezed, bumped, and rained on. The transport vehicle should be keptclean and dry, avoiding mixing with other chemical products.
