PAC

PAC,or polyaluminum chloride,is a chemical compound that is commonlyused in water treatment processes.PAC is typically a white or yellowishpowder that is soluble in water.It has a slightly acidic odor and can becorrosive to some metals.PAC is a coagulant that is formed by mixingaluminum chloride and hydrochloric acid.It is available in both liquid andpowder form and is used to remove suspended particles,turbidity,and colorfrom water.It works by neutralizing the negative charge on suspendedparticles and causing them to clump together,making them easier toremove from the water.

There are several different types of PAC,each with its own unique physicaland chemical properties.Some of the most common types include:

Basic PAC:This type of PAC has a low aluminum content and is often usedin low-turbidity water treatment processes.

PAC with a high aluminum content:This type of PAC has a higher aluminumcontent and is often used in high-turbidity water treatment processes.

PAC with a high basicity:This type of PAC has a high basicity and is oftenused in water treatment processes where pH levels are low.

OverallPAC is a versatile chemical compound that is widely used in watertreatment processes.By understanding the different types of PAC and theirunique properties,it is possible to choose the right type of PAC for a specificwater treatment application.
