Products & Services: Drinking Water Treatment

Measurement and control center

The DEPOLOX® 700 M analyzer is designed for measurement and limited control tasks in the drinking and process water industry. The analyzer can incorporate up to six well-proven measurement parameters: free chlorine, total chlorine, pH, oxidation reduction potential, conductivity and temperature. The device uses a 7” color touch panel for an intuitive user interface and an LED lit flow cell that can be programmed to change color in case of an alarm condition.

Granular activated carbon

Cabot Corporation’s HYDRODARCO® 4000 and NORIT® GAC 400 are granular activated carbons (GAC) for the removal of poly- and perfluoroalkyl substances (PFAs) including perfluoro­octanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in public water systems. Unlike other types of activated carbon, these have optimized pore size distributions that provide a large quantity of adsorption sites for PFOA and PFOS removal. These products resist interference from natural organic matter that can cause partial or complete blockage of the activated carbon pore structure, leading to reduced adsorptive capacity for target contaminants including PFOA and PFOS.

Water system protection

Val-Matic’s VaultSafe® family of products is designed to protect potable water systems. With its dual chambers and float checks, the FloodSafe® Inflow Preventer prevents contaminated water from passing through it, thus preventing it from entering the air valve outlet and compromising the potable water system. With a bidirectional hingeless disc and wafer design, the FrostSafe® air damper minimizes the thermal exchange of cold and warm air in and out of a vault to help prevent freezing. The VentSafe® security cage safeguards vent pipes against the hazards of nesting animals and intentional harmful activities because of its hemispherical screened security cage.

NSF/ANSI-61 and NSF/ANSI-372 certified flow meter

McCrometer’s FPI Mag® meter has completed and passed the certification process to meet NSF/ANSI-61 standards, which involves specialized inspections, destructive testing, and rigorous scrutiny to ensure all parts of a flow meter that come into contact with water are safe and will not become a contaminant. Designed with electromagnetic flow sensor technology for best-in-class accuracy: ± 0.5% from 1 ft/s, up to 32 ft/s (0.3 m/s to 10 m/s). Featuring ease of use and total cost savings, it is suitable for a wide range of municipal and industrial applications.

Monitor chemical usage

The Carboy-Scale™ from Force Flow allows operators to accurately monitor how much chemical is being used in their treatment process. The scale platform is 100% PVC plastic, making it immune to corrosion. The SOLO G2® digital weight indicator displays the remaining chemical in increments as small as 1/10 lb. Three platform sizes are available to accommodate drums from 5 to 55 gallons.

Sodium hypochlorite metering

The new Qdos 20 pump has been developed to offer highly accurate sodium hypochlorite metering in disinfection applications with flow rates to 20 liters per hours at a maximum of 7 bar pressure. Features low total cost of ownership and is designed as a drop-in replacement for diaphragm pumps. Qdos pumps also include the ReNu pump head for single, no-tools maintenance. Its intuitive interface provides simple control of the pump via manual, 4-20 mA, contact or PROFIBUS control. The brushless DC motor control maintains flow accuracy of +/-1% with a repeatability of +/-0.5% and a turndown ratio of 3330:1.
