Collection of new products of special interest to the industrial water and wastewater markets.
The E-Z Tray® Air Stripper is a sliding tray, stainless steel air stripper ideal for removing volatile organic compounds (VOCs) from contaminated groundwater and waste streams. As contaminated groundwater enters through the top of the air stripper, air bubbles are forced by blower pressure up through the perforated trays. This creates a turbulent froth zone with an extremely high air-to-liquid surface area for mass transfer of VOCs from liquid to air. Using the froth instead of a conventional tower packing delivers high VOC removal efficiencies, even under fouling conditions. The system is easy to inspect and maintain, even during use.

Ion exchange resins
DOWEX MARATHON™ ion exchange resins from Dow Water & Process Solutions feature uniform beads that exhibit faster kinetics than conventionally sized resins and help improve regeneration efficiency and increase operating capacity. Products include a suite of strong and weak acid cation exchange resins, and strong and weak base anion exchange resins for use in both packed bed and layered bed systems. The lineup allows operators to use the best combination of resins with their vessel type to achieve extremely low unit cost of demineralized water, high regenerability, and reduced waste volume.

Slurry and digestate processing system
Kumac, WELTEC BIOPOWER’s slurry and digestate processing system, is a fully automated processing system that reduces liquid manure and digestate volume by 50 percent. In a four-stage procedure, clear water, liquid fertilizer concentrate and valuable solid matter are extracted from the source material. The processing system represents a sustainable, economic solution for mitigating the impact of the nutrient surplus by reducing the volume of slurry and improving its transportability.
Flowmeter verification tool
KROHNE’s OPTICHECK flowmeter verification tool provides in-situ verification for mass and other flowmeters. It enables operators to perform preventive maintenance and responsive service to ensure that installed flowmeters are performing to specification. When the tool is connected in-line on site, it gathers measuring data to ensure that the flowmeter is performing within 1% of the factory calibration with a confidence level of 95%. The baseline for comparison can be historic repair data from the factory or on-site test results after performing a full verification. The device comes with all cables and accessories for easy connection and handling.
Automatic volumetric feeder
Scaletron Industries has introduced a new line of volumetric screw feeders for metered dispensing of powdered or pelletized chemicals into water, wastewater and chemical treatment processes. The Model VMF-28™ auger-style feeders feature a fully integrated Scaletron scale. Precise dosage amounts are automatically weighed and added to treatment processes without requiring an operator to measure and weigh amounts. Data is displayed at a central monitoring station where operators can quickly make adjustments as necessary from the control panel. Besides saving operators time, the new VMF feeders improve accuracy because the integrated scale continually monitors weight loss or gain.
