Praxair presents wastewater treatment offerings at WEFTEC 2018
Praxair Inc. will deliver a technical presentation and exhibit in booth #3045 at the Water Environment Federation Technical Exhibition and Conference (WEFTEC) Sept. 29–Oct. 3, 2018, at the Ernest N. Morial Convention Center in New Orleans.
Dr. Randall Marx of Praxair’s research and development team will present, "Aeration Tank Odor Eliminated Through Pure Oxygen Injection Into a Jet-Aeration System" during Session 507 on Wednesday, Oct. 3, at 9:30 a.m. in Room 245. Pure-oxygen aeration with equipment such as the Praxair I-SO in-situ oxygenator can address septic odor conditions in aeration basins by reducing emissions and restoring aerobic conditions. Praxair’s exhibit will include supply and distribution methods of on-site, bulk and packaged gas products as well as processing equipment. Exhibit visitors will learn more about the company’s experience in aerobic wastewater treatment, offering oxygen plant upgrades for aging UNOX systems, as well as pH control with carbon dioxide and other technologies to help meet specific water and wastewater management goals.
Additionally, attendees can meet with Praxair’s experts to discuss state-of-the-art Vacuum Pressure Swing Adsorption (VPSA) supply systems, which are capable of meeting gaseous oxygen needs from 30 to 200 tons per day. VPSA supply is a cost-effective way to supply oxygen to water treatment equipment.
GF Piping Systems to feature sensing technologies at WEFTEC 2018
The 4630 analyzer offers a turnkey solution for accurately measuring free chlorine. Its amperometric sensing technology provides an improved solution over traditional chlorine monitoring by enabling more accurate measurement in real-time and eliminating the need for reagents. Typical uses include primary/secondary disinfection, water distribution, de-chlorination, algae growth prevention, slime (bio-film) control, and taste and odor control. The 4630 incorporates a clear flow cell, flow regulator, sensors, filter and rotameter all in one compact unit.
The 2551 and 2552 Magmeter Flow Sensors feature no moving parts to wear or foul, high accuracy sensing, empty pipe detection and bidirectional flow capabilities. The units measure flow in fluids containing a high content of particles, solids and fibers, making them ideal for applications with dirty fluids.
The Signet 2551 Magmeter is an insertion style electro-magnetic flow sensor. Frequency/S3L output is bidirectional, while the 4 to 20 mA output can be set for single or bidirectional flow. Performance characteristics include a dynamic flow range of 0.15 to 33 ft/s (0.05 to 10 m/s) with repeatability of ±0.5 percent of reading. Superior linearity of ±1 percent reading provides performance in harsh environments.
The Signet 2552 Metal Magmeter, a rugged insertion flow sensor, permits hot-tap access to the pipe stream. This design allows quick, easy installation or maintenance without system shutdown, reducing overall costs. Three output choices are incorporated into a durable metal housing. It can be mounted into pipe sizes from 2 to 48 inches (DN50 to DN1200) and features a dynamic flow range of 0.15 to 33 ft/s (0.05 to 10 m/s) with repeatability of ±0.5 percent of reading at 25°C.
NETZSCH to showcase pump technology at WEFTEC 2018
NETZSCH Pumps North America will showcase its pump technology in Booth #1319 at WEFTEC 2018. The N.Mac Twin Shaft Grinder on display is designed to fragment a variety of materials and is ideal for wastewater treatment, biogas and biomass plants, food, animal processing and other waste and industrial applications. Featuring cartridge cutting knives for quick, simple replacement and servicing, the N.Mac offers quenched lubricated mechanical seals for dry running capability. The mechanical seal cartridge design – a leak-free combination of mechanical seal and bearing cartridges – enables quick, simple replacement and servicing. Available in both channel and inline (flanged) housing construction, the N.Mac can be installed into effluent channels or upstream from a pump.
Also to be highlighted is the low-maintenance FSIP NEMO progressing cavity pump and its new xLC unit. Providing full access to all of the pump’s rotating parts, the FSIP pump allows users to conveniently open the pump cavity on-site and dismantle all rotating parts and simply install them again without having to remove the pump or disconnect the piping. This reduces installation complexity and maintenance time. The new addition to the NEMO’s portfolio, the xLC unit, triples the service life of the pump, particularly when conveying difficult, abrasive media. When wear occurs in the rotor-stator system, the new xLC unit allows the performance of the pump to be re-established by adjusting the preload between the conveyor elements. NEMO progressing cavity pumps offer continuous, pressure-stable, gentle and low-pulsation conveyance of almost any substance, including sludge. NEMO FSIP is available in six sizes (NM045 to NM105) for flow rates over 800 gallons per minute.
The iFD-Stator 2.0 showcased at the booth features a two-part, reusable stator housing and replaceable elastomeric stator. The iFD-Stator 2.0 design combines efficiency, economy and environmental safety in one system. Compatible with NEMO NM series progressing cavity pumps NM21 through NM063 with larger sizes in development, the iFD-Stator 2.0 reduces energy and maintenance costs.
Also on display will be the TORNADO T2 Rotary Lobe Pump, with its FSIP design. This self-priming, valve-less, positive displacement pump is ideal for any kind of liquid, including media containing gas, solids or fibrous matter.
Sensaphone to feature Sentinel PRO with cloud technology and app at WEFTEC 2018
Sensaphone will feature its Sentinel PRO remote monitoring system at WEFTEC 2018, booth #744. The Sentinel PRO system provides water and wastewater facility operators 24/7 remote monitoring, data acquisition and real-time visibility of all sites from a user-friendly cloud-based dashboard. The Sentinel PRO system seamlessly interfaces with any water/wastewater processing equipment that uses a PLC with Modbus sensors. Supporting both Modbus RTU-485 and TCP protocols, the system can monitor up to 64 Modbus registers and 12 different digital or analog status conditions, including power, pump status, tank level, turbidity, flow rate, pressure, temperature, humidity and water leaks.
The Sentinel PRO system immediately notifies users of any readings outside of preset parameters and potential threats to pumps and systems. Operators can view data values in real-time from their phone via the free iPhone/Android app or the website. Users can set alarms, acknowledge alerts, review data and generate reports from the easy-to-use dashboard. For remote locations without internet or Ethernet connectivity, a 4G cellular Sentinel PRO system is available that communicates through AT&T or Verizon networks.
Sensaphone will also showcase its full line of remote monitoring devices and sensors for the water treatment industry including:
The SAT4D system communicates via satellite and is ideal for facilities in the most remote locations where telephone, Ethernet and cellular connections are unavailable. It can monitor up to four critical conditions 24/7, including tank floats, pump status, security, power failure and equipment malfunction. When an alarm occurs, the system sends notifications to up to eight telephone numbers and six email or text messages.
The Express II system is ideal for 24/7 monitoring of conditions such as pump failure and tank levels and is expandable to include up to 40 channels. The system can send alerts to up to 48 people with custom phone calls. It easily integrates with existing floats, pump alarm outputs and level transducers. The internal rechargeable battery backup provides 12 hours of continuous monitoring and alerts in the event of a power outage.
The Sensaphone 1400 and 1800 systems for smaller operations have four and eight external sensors.
Also, Sensaphone Water Quality Sensors measure oxidation-reduction potential (ORP), pH, dissolved oxygen (DO) and toroidal conductivity. The sensors are compatible with most Sensaphone remote monitoring systems, which provide the necessary alerting and data logging functionality.
Sensaphone’s Vibration Sensor can be permanently mounted on equipment like pumps, motors and generators to continuously monitor vibration velocity and detect unusual conditions. The sensor provides constant real-time data to an accompanying Sensaphone monitoring device, which sends an immediate alert to designated personnel when vibration levels fall out of range. The Sensaphone Vibration Sensor is compatible with all Sensaphone monitoring devices that accept a 4-20 mA input.
