Advanced formulations designed to address extreme seasonal water turbidity variations and high regulatory compliance standards in South America.
Colombia’s distinct geography—defined by the Andean cordilleras, extensive river systems like the Magdalena and Cauca, and heavy rainfall cycles—imposes unique pressures on municipal and industrial wastewater facilities. High seasonal turbidity, rapid pH fluctuations, and the presence of fine colloidal suspensions are common challenges faced by plant operators in cities like Bogotá, Medellín, Cali, and Barranquilla.
To comply with Colombia’s strict environmental laws, including Resolución 0330 of 2017 (RAS) and Resolución 2115 of 2007 for drinking water quality, municipal utilities and industrial operators are moving away from traditional metal salts. Traditional aluminum sulfate often struggles in low-temperature Andean waters and consumes valuable alkalinity, necessitating high dosages of neutralizing agents like lime or soda ash. This is where Aluminum Chlorohydrate (ACH) serves as a highly efficient, modern solution.
ACH is a highly concentrated, polymeric inorganic coagulant featuring a high basicity of 83% to 84% and an active Al₂O₃ content of 23% to 24%. Unlike standard alum, which has zero basicity, ACH has a pre-hydrolyzed polymeric structure that enables rapid charge neutralization and sweep flocculation. The benefits are clear: faster floc settlement, significantly lower sludge production (up to 50% reduction in municipal clarifiers), and minimal impact on the treated water's pH, eliminating the cost of secondary neutralization chemicals.
Due to its high basicity (83%+), ACH preserves alkalinity in Colombian raw waters, removing the need for costly post-coagulation pH adjustment chemicals.
Forms dense, heavy flocs that settle rapidly, excelling during heavy Andean rainy seasons when raw water NTU levels spike unpredictably.
ACH generates up to 50% less sludge volume compared to alum, helping operators reduce disposal costs under Colombian landfill regulations.
Our high-purity Aluminum Chlorohydrate (ACH) is engineered to meet the demanding requirements of key industries across Colombia:
For large municipal waterworks operating under strict turbidity and residual monomeric aluminum limits, ACH provides a reliable solution. Its pre-polymerized aluminum species, specifically the stable Al13 polymer, guarantee low residual aluminum levels in finished potable water, safeguarding public health in urban centers.
In paper mills, ACH serves as a highly effective retention aid, anionic trash scavenger, and sizing controller. It operates efficiently in neutral-to-alkaline papermaking environments without introducing excessive sulfate ions, which can lead to equipment corrosion and hydrogen sulfide odors.
Treating organic-rich wastewater from coffee washing (beneficio de café) and palm oil mills requires powerful charge neutralization. Using a combination of our ACH and high-molecular-weight Polyacrylamide (PAM), facilities can rapidly separate organic suspended solids and reduce chemical oxygen demand (COD).
In the oil and gas fields of Santander and Casanare, our thermal-stable ACH and cationic polymers are used to break oil-in-water emulsions, allowing operators to achieve low oil-in-water (OIW) ppm values before reinjection or surface discharge.
