Activated Carbon Systems


FILTRASORB SENTRY activated carbon from Calgon Carbon can be used in a variety of liquid phase applications for the removal of dissolved organic compounds. Its 8x30 mesh size provides improved pressure drop performance while delivering adsorption capacity for PFAS, making it a suitable granular activated carbon for surface water treatment. It also removes other contaminants of emerging concern, such as 1,2,3- TCP, as well as legacy contaminants like taste and odor compounds, organic color, total organic carbon and DBPs. It is made from select grades of bituminous coal through a process known as re-agglomeration to produce a high activity, durable, granular product capable of withstanding the abrasion associated with repeated backwashing, hydraulic transport and reactivation for reuse. The raw coal is mined and subsequently manufactured into GAC in the United States to ensure the highest quality and consistency in the finished product. 800-422-7266;

Operators Unlimited custom chemical feed systems

From wasted chemicals to permit violations, operational efficiency can be controlled and maximized through proper chemical dosing. Operators Unlimited designs custom chemical feed systems for all areas of the facility. Cooling towers, boiler water, process and solids all benefit from proper dosing. If a chemical feed system is improperly designed, the facility could face several issues including permit violations, increased operational costs, increased maintenance costs and additional labor costs. The plant could potentially overuse chemicals, thus contributing to safety issues, waste and create a system performance issue. An issue in performance can lead to more repairs and the need for replacement parts. As a result, the plant could suffer downtime with consequences for the entire manufacturing facility. Therefore, the design and implementation of a quality chemical feed system that releases the correct amount of chemicals for your exact wastewater treatment needs can be an essential component of a treatment facility. 864-228-1131;

Veolia Water Technologies Hydrex

The Hydrex odor control process from Veolia Water Technologies is a redox chemical reaction that combines the Hydrex catalyst with hydrogen peroxide to produce hydroxyl free radicals that quickly and efficiently oxidize sulfide and other malodorous compounds. The process is pH neutral and the only byproduct is dissolved oxygen. The process can be used in headworks, lift stations in the collection system and biosolids dewatering. The catalyst can also be used in the vapor phase in chemical scrubbers, replacing the current use of caustic and bleach for hydrogen sulfide reduction with minimal media fouling and pH adjustment required. The process provides a rapid reaction, using a biodegradable, nonhazardous, cost-effective solution. A capital equipment option customized for the catalyst is designed to treat up to 100 ppm hydrogen sulfide is also available where a new scrubber is required. 919-677-8310;


Force Flow Chlor-Scale and Halogen Eclipse

To protect chlorination systems from dangerous leaks, the Halogen Eclipse emergency valve shut-off system instantly closes the container valve when a signal is received from a leak detector, panic button or SCADA. The actuator quickly installs on the tank without the use of any tools and allows manual operation of the valve while in place. During an emergency shutdown event, the system measures the actual torque applied to the valve to ensure that the valve is closed to Chlorine Institute recommended standards and provides remote confirmation that the emergency close operation successfully closed the valve. The Chlor-Scale from Force Flow safely cradles a chlorine ton container while providing critical feed and chemical inventory information. Know in real time exactly how much chlorine has been fed and how much remains in the tank. It can warn of excessive or insufficient feed rates and can be remotely monitored from a PLC or SCADA system. 925-893-6723;

HF scientific, a Watts Brand CLX Online Chlorine Analyzer
