Volumetric titrator

The AQUACOUNTER® Karl Fischer Volumetric Titrator (AQV-2200S) has small-volume titration cells requiring only 20 mL of titration solvent for accurate measurements. The high-end titrator is designed for a wide range of water content — from 100 ppm to 100% — with maximum capability for automation and upgrades. Combining one additional station with either a volumetric or coulometric module enables two different measurements to be performed at the same time. JM Science Inc. (Grand Island, N.Y.).

 

System technology

The Moyno® 2000 HS system is designed for the wastewater treatment industry. The system is designed to pump filter cake far distances with high volumetric efficiencies. The twin-screw feeder supplies a constant, pressurized feed rate to the pump, resulting in a 100% pump cavity fill rate. The system features an integral hopper with a twin-screw auger feeder and a specially designed progressing cavity pump that efficiently handles dewatered municipal solids to more than 50% solids. Moyno Inc. (Springfield, Ohio).

 

Energy-efficient mixers 

GridBee™ grid-connected mixers and circulators are designed to provide superior, cost-effective mixing for applications where utility power is readily available. The mixers help solve water quality problems in potable-water storage tanks, wastewater lagoons and basins, and park and golf course ponds. The patented long-distance circulation technology creates a near-laminar flow that prevents and controls blue-green algae in lakes and raw-water reservoirs, reduces aeration runtime in wastewater, and eliminates stagnation and thermal stratification in potable-water storage tanks. SolarBee Inc. (Dickinson, N.D.).

 

Software  

AQUARIUS 3.0 software processes time-series data sets, consolidates water data from multiple sources, performs data quality control, and creates rating curves and reports in real time. The software is designed to enable water agencies to balance the increasing demands on water resources from drinking water, hydropower, irrigation, recreation, and nature conservation. Aquatic Informatics Inc. (Vancouver, British Columbia). 

 

Bar screen 

The Bar Screen Monster™, the first self-contained reciprocating-rake bar screen, is designed to capture and transport large amounts of wastewater debris to the discharge point. With a completely submersible drive, the unit is compact, resulting in low headroom. It accommodates channel widths from 0.8 to 2 m (2.5 to 6.5 ft) and depths up to 3.7 m (12 ft). The rake speed operates at a minimum 6 m/min (20 ft/min). JWC Environmental (Costa Mesa, Calif.).

 

Agitators 

Chemineer Model 20 HT/GT agitators are designed for a wide range of service in the water and wastewater treatment industry, including aeration, nitrification, denitrification, aerobic and anaerobic digestion, and clarification. The agitators feature a high-efficiency gearbox designed specifically for agitator service. Models are available in right-angle and parallel-shaft configurations. Chemineer Inc. (Dayton, Ohio).

 

Stormwater treatment system 

The StormwateRx system removes dirt, sediment, fine particulates, hydrocarbons, and dissolved metals from stormwater runoff. The system uses Retenu™, Aquip®, and Purus® systems in a stormwater treatment train to help ensure a high level of pollutant removal and water purification prior to releasing stormwater back into the environment. StormwateRx LLC (Portland, Ore.).

 

Processing system 

The SFT-150 system is designed to perform extractions and run reactions in supercritical-fluid media. The modular design makes altering the unit’s basic configuration easier and adapts the unit to meet new or evolving application needs. At the heart is a stainless steel vessel capable of containing supercritical fluids at pressures up to 10,000 lb/in.2. The system comes standard with a 100-mL, hand-tight sample vessel. Supercritical Fluid Technologies Inc. (Newark, Del.).
