Carbochem has developed a special grade of granular coal-based carbon to provide a neutral pH without requiring acid washing. This grade is produced by a proprietary process that doesn’t require extensive back washing to achieve a stable pH. The method provides significant benefits when placing new carbon filters into service in terms of minimizing downtime and thereby reducing costs. It also contributes to achieving the desired water quality. Carbochem offers a full line of activated carbon with ANSI/NSF Standard 61 and ISO 9002 certification.
