EDR desalination
With its new Electrodialysis Reversal (EDR) platform, GE Water & Process Technologies enhances its portfolio of advanced water and wastewater treatment solutions. EDR desalination technology offers up to 94% recovery, removing salt, radium, arsenic, perchlorates and other potentially harmful contaminants from tough-to-treat well and surface waters. Using an electrochemical chlorine-resistant, silica-tolerant membrane separation process that allows selective passage of ions in solutions, it produces high-quality water for a variety of industrial applications, such as cooling and boiler make-up water, and its rugged membranes and high chlorine tolerance make it ideal for a variety of wastewater reuse projects. Adjustable electricity enables salts removal control and energy optimization. GE Water & Process Technologies, Trevose, PA, 905-465-3030, www.gewater.com
Wastewater separation
JWC Environmental’s Monster Separation System can now incorporate a highly-reliable vortex grit removal system named Grit MonsterTM, or a robust bar screen called Catenary MonsterTM. JWC signed an agreement earlier this year with Mabarex Inc. of Montreal, Canada, to license the technologies. The Monster Separation System consists of a fine screen with 2, 3 or 6mm openings for solids removal followed by the award-winning Screenings Washer Monster® for washing and compacting. The Grit Monster incorporates a proven vortex swirl concentrator and choice of an air-lift pump or a specialized grit pump to remove fine particulate. The Catenary Monster is a mechanically raked bar screen that’s custom made for each site and can fit in large channels up to 16’ wide (5m) and almost any depth.

Swing check valves
Danfoss Flomatic Corp. introduces additions to its growing Flo-FlexTM family of rubber disc swing check valves. The model 745 series has a flange-to-flange lay length that meets ANSI/AWWA C508-01 for the water and wastewater industry. The new Model 745BF features a backflush device to manually operate the valve in the field. Common applications for this would be backflushing, system testing, priming of the pump, draining the lines and system testing. The new Model 745PI provides a valve disc position indicator that gives a distinct indication of disc position during operation in the field. It features a 45° seat with a steel/ductile iron valve reinforced rubber disc. The Ductile Iron 125# Flanged Body is Fusion Epoxy coated and can be used as pipe line cleanout.

Wireless pipeline inspection
The patented QuickView® pipeline zoom camera can now transmit real-time inspection footage wirelessly to any truck-mounted video monitor display or recorder. A new wireless option allows convenient remote viewing during inspection, multiple viewers, and the collection of easement inspection video directly into data collection software. Video can be transmitted up to 1000 ft line-of-sight (300 ft otherwise) using one of 8 user-selectable channels in the 5.725-5.875 GHz range. This functionality adds only minimal weight and power consumption to the system. Envirosight LLC, Randolph, NJ, 973-993-1570, www.envirosight.com
Multiparameter measurement
Myron L’s TechPro II instruments have all the functionality of the previous TechPro line but have been completely redesigned to include improved features with greater performance. The TP1, TPH1, and TH1 deliver repeatable results in critical water quality parameter measurements of conductivity and TDS (TP1 and TPH1), pH (TPH1 and TH1) and temperature. The instruments are waterproof, buoyant and easy to calibrate. Myron L Co., Carlsbad, CA, 760-438-2021, www.myronl.com
Pipeline strainer
The Eaton Model 50 Duplex Basket Strainer protects piping system components like meters, pumps, and instrumentation from damage and reduces expensive unscheduled downtime. Dual strainer baskets operate independently within a single housing to remove unwanted particulate matter from system flow. Switching flow from one basket to the other, so the dirty basket can be cleaned, is accomplished by moving the operating handle through a 90° arc. Eaton Filtration LLC, Elizabeth, NJ, 908-787-1000, www.filtration.eaton.com
Self-anchoring pipe fittings
Viking Johnson has added a DN300 (12”) size to its patented FlexLock range of self-anchoring pipe couplings and flange adapters an alternative to on-site welding, harnessing or thrust blocks. Suitable for ductile iron or steel pipes, FlexLock has stainless steel teeth molded into the gasket that grip the outer surface of the pipe as the bolts are tightened. This prevents pipe pullout under pressure yet still allows for angular deflection, making the fittings ideal for pipes installed above ground level or in soft ground.

Septic system recovery
Failing wastewater drainfields are rejuvenated in as little as two weeks with the Aquaworx Remediator. It uses a fine bubble air diffuser to introduce oxygen into the bacterial growth media column so the bacteria can begin to thrive and consume organic matter. Installed with minimal landscape disruption, this simple, unique solution is inserted into the existing septic tank and reverses the biological clogging process causing the failure. With odors and wet areas in yards are eliminated in as little as two weeks, it’s inexpensive to install, operate and maintain. Aquaworx, Old Saybrook, CT, 877-278-2979, www.aquaworx.com
Overflow alarm system
The new ADS FlowAlertTM, Nova Technologies unit ADS LLC, is a depth-based alarm system offering an economical alternative for wastewater collection system monitoring. This new wireless alarming system supports both float switches and a depth sensor. It can be deployed as a stand-alone unit or as part of a comprehensive flow monitoring network and does not require a confined space entry. Two float switches provide date-and time-stamped depth notification. An optional depth sensor logs actual depth readings for use in depth trending and flow calculation. ADS LLC, Huntsville, AL, 800-633-7246, www.adsenv.com
