Ferric Chloride

Ferric chloride solution is a staple coagulant in municipal water treatment, valued for its efficacy in removing suspended solids, colloids, and metals from raw water. When introduced into the water, it reacts to form flocs of iron hydroxide that ensnare impurities, which can then be removed by sedimentation and filtration. This process not only improves the clarity and purity of the water but also aids in reducing pathogen levels, contributing to the overall safety of municipal drinking supplies. The solution’s NSF certification is critical, ensuring that it meets the stringent health standards required for substances used in the treatment of water intended for human consumption.

In the pulp and paper industry, Ferric Chloride is utilized primarily for its effectiveness as a coagulant in the treatment of process and wastewater. It plays a pivotal role in enhancing the clarity and quality of water by facilitating the aggregation and removal of fine suspended particles and impurities through the coagulation process. This not only improves the recycling capabilities of the water used within paper mills but also ensures that the effluent discharged meets environmental compliance standards. Moreover, Ferric Chloride is instrumental in the color removal process from the wastewater, a common requirement in paper mills where dyes and inks can contaminate water streams. The addition of Ferric Chloride helps in achieving a significant reduction of these color pollutants, contributing to a cleaner and more sustainable operation. Additionally, its utility extends to the conditioning of sludge, where it aids in dewatering processes, making the sludge easier to handle, treat, or dispose of, thereby enhancing overall operational efficiency.
