Cationic acrylate esters are susceptible to base hydrolysis above pH 6, resulting in the loss of cationic charge on the polymer. The rate of hydrolysis is concentration- and temperature-dependent. In contrast, cationic acrylamide copolymers
Ion Exchange (IX) - DuPont
Ion exchange (IX) is the reversible interchange of ions between a solid and a liquid such as water. Ion exchange resins remove harmful contaminants from liquids, replacing them with beneficial, desired ions. Ion exchange is used in water

- Is poly-aluminum chloride a good coagulant for wastewater treatment?
- As a common and low-cost coagulant, poly-aluminum chloride (PAC) may be widely used for wastewater treatment. In this article, the impacts of PAC on activated sludge and the treatment efficiency of sequencing batch reactor were investigated over 100 d for domestic wastewater treatment.
- Is polyaluminum chloride a coagulant?
- Inorganic coagulants such as polyaluminum chloride (PAC) have been used for years to treat water and wastewater. However, PAC as a coagulant can harm the living environment as it is toxic to humans and aquatic ecosystems. The use of natural and biocompatible materials such as sodium alginate as coagulant-aid can reduce the use of PAC.
- Does polyaluminium chloride remove colour and cod from semi-aerobic water?
- This research examined various experimental conditions for application of Polyaluminium Chloride (PAC) for removing colour, COD and ammonia from semi-aerobic. The removals of colour, COD and ammonia were up to 93%, 56% and 32%, respectively, at an optimum dosage of 2000 mg/L PAC.
- How PAC is used in water and wastewater treatment plants?
- The preferred capability of PAC in water and wastewater treatment plants is the removal of colloids and suspended particles, metal ions, phosphates, organic materials, hazardous metals, and even color . Currently, PAC is available on the market as either liquid or powder product .
