Odor control
ECO2 SuperOxygenation technology is a preventative treatment for odor control. By dissolving pure oxygen into a wastewater side stream and pumping it back into the system, aerobic conditions are maintained and H2S formation prevented. The system can save money on alternative, sometimes hazardous chemicals, and eliminates the need for covers and scrubbers.

Grit removal
John Meunier will showcase its MectanV induced vortex grit removal technologies. The innovative variable angle grit removal configuration and separator system is the result of over two years of research work and CFD analysis. The patent-pending design effectively removes more fine grit for each grit size analyzed than a conventional grit removal system.

Baffle system
Studies by the USEPA and others show that density currents form in all activated sludge secondary clarifiers, regardless of size and shape, and have a significant, adverse effect on clarifier performance. The new NEFCO® Stamford Density Current Baffle System 2.0 is specifically designed to intercept and dissipate these currents and redirect their flow back into the main clarification volume of the tank increasing hydraulic capacity and producing as much as a 70 percent reduction in total suspended solids.
TOC analyzers
With a wide sample range from 4 μg/L to 30,000 mg/L, Shimadzu’s TOC-L is suitable for analyzing ultra-pure to highly contaminated samples of water including wastewater and drinking water. Consisting of four models including PC-controlled and standalone versions, the analyzer uses Shimadzu’s 680° C combustion catalytic oxidation method to efficiently analyze all organic compounds.

Pumping aid
The WEMCO®-Hidrostal® Prerostal® Prerotation system is an uncomplicated method of automatically adjusting pumping volume to varying inflow rates using a constant speed motor/pump. It combines the screw centrifugal impeller characteristics of the WEMCO®-Hidrostal® pump with a specifically configured vortex inducing chamber around the suction pipe of the pump. The chamber uses gravity to impart a fluid spin in the same direction of rotation as the pump impeller, and this spin produces a flow reduction without the necessity of changing pump speed.

Valve controllers
Universal Valve Controllers (UVC) from OCV are the “brains” for the company’s Series 22 Electronic Control Valves. The UVC is used in conjunction with the 115-3 or 115-36 diaphragm actuated, automatic control valve to provide a digital solution to fluid control applications.

Rubber check valves
Proco Products is a supplier of expansion joints and other piping related products. The company’s newest product is the ProFlex series 700 Rubber Check Valve. The valve is manufactured completely from fungicide- and barnacle-resistant rubber. It is impervious to the daily operational vulnerability affiliated with the water and sewage industry such as rust, freezing, corrosion and seizing often found in the check valve industry.

MBR system
The TORAY “MEMBRAY” submerged flat sheet membrane bioreactor (MBR) module, when used as a component of a MBR system, effectively removes suspended solids from activated sludge. This microfiltration module in a plate-and-frame configuration consists of flat sheet PVDF membranes that are cast on a polyester, non-woven fabric as the base layer.

Backpressure valve
Plast-O-Matic Valves has introduced a new automatic valve that performs multiple functions in a piping system including pressure relief, backpressure control, pump bypass, and anti-siphon protection. The new, ½” size, lug-mounted Series RVDT uses an adjustable non-wetted spring to control backpressure in a piping system. The set-point is adjustable, and once the set pressure is reached, the valve begins to open. It will allow the rated full flow at approximately 40% over the set pressure. This operation enables the valve to provide a controlled obstruction in a piping system as needed.

Process control
The Burkert mxControl Type 8620 unit is designed to automate the control of process variables within a water treatment system. It can reduce controller and instrument costs by as much as half by integrating all control, monitoring and display features as well as data and event logging functions into one compact unit. It incorporates multi-parameter panel mounted transmitters into single platform multi-parameter controllers. The controller is able to be configured to display, transmit and record flow, pressure, pH/ORP, conductivity, turbidity, O2, O3, Cl2, level and temperature through standard 4-20mA inputs.
