Cetylpyridinium chloride (CPC) is a quaternary ammonium compound used in various industries for its antimicrobial properties. It belongs to the class of drugs known as antiseptics and disinfectants.
CPC is important for hygiene and preventing infections. But to avoid risks to the environment and health, it should be removed from water.
Cetylpyridinium Chloridefinds applications in medicine for both humans and animals, including use in oral care products, throat lozenges, and veterinary antiseptics.
Cetylpyridinium Chloride removal from water using our specialist water treatment is crucial to mitigate aquatic ecosystems and safeguard public health.
We have experience in reducing Cetylpyridinium Chloride by 92% for an industrial client.
How it works
Several techniques are currently used to remove cetylpyridinium chloride from water; each has its pros and cons. It is important to consider factors such as CPC concentration, water volume, and economic feasibility when choosing a treatment method.
Cetylpyridinium chloride removal by adsorption, such as activated carbon filtration, have proven effective. Activated carbon has a high affinity for organic compounds, including CPC, and can efficiently adsorb them from water. However, the disposal of spent carbon and the potential release of adsorbed contaminants during reactivation processes are challenges.
Reverse osmosis for removing cetylpyridinium from water is another method used. It employs a semi-permeable membrane to separate contaminants from water molecules. RO can effectively remove various organic compounds, including CPC. However, it requires significant energy input and may not be cost-effective at larger scale, but it is one of the options for cetylpyridinium removal.
Granular Activated Carbon (GAC) is commonly used in water treatment processes due to its ability to adsorb a broad range of organic compounds. GAC has shown promising results in removing CPC from water, making it a viable option for industrial applications. However, disposal of spent carbon can be challenging and requires careful management to prevent contaminant release along side large-scale implementation may require significant space and operational costs.
