Water / Wastewater 19 New compact 12V submersible pump for groundwater sampling


Solinst Canada Ltd. has introduced a new addition to their groundwater samplers product line – the Model 415 12V Submersible Pump provides an effi cient means of purging and obtaining groundwater samples from 2” OD monitoring wells. The 12V submersible pump and 12V pump controller are lightweight, portable, and easy to set up, deploy and operate. The pump’s sleek, short design (nominal 6”) ensures it fi ts easily down wells that might not be straight.


The 12V submersible pump cable connects to the 12V pump controller, which then clips to a 12V power source, such as a 60 amp AGM battery or higher, or a car, truck or marine battery. Simply turn the dial on the 12V pump controller to increase the voltage to the controller, which turns the pump’s motor faster and increases the fl ow rate. The Solinst 12V Submersible Pump is capable of pumping groundwater from 36.5 m (120 ft.) below ground surface, with fl ow rates up to 13.5 L/min (3.6 US gpm) in shallow conditions. The continuous fl ow rate is very easy to adjust using the 12V pump controller’s single dial.


Save time and reduce sampling costs by connecting a new Model 800M Mini Packer to the 12V submersible pump intake. This will isolate your sampling zone and minimise purge volumes. The Solinst 12V Submersible Pump is ideal when sampling using three volume purge protocols or performing constant head tests in high K (hydraulic conductivity environments). For use in environments with high suspended solids, an optional in-line disposable fi lter threads onto the pump’s intake.

56753pr@reply-direct.com New, advanced clamp-on fl owmeters for water,


wastewater, and other process industry applications Prosonic Flow W 400 brings the modern technology of Endress+Hauser’s Proline device series to clamp-on ultrasonic fl owmeters. The W 400 clamp-on and I 400 insertion units provide comprehensive process monitoring with long-term cost effi ciency and extensive diagnostics. These sensors pair with Endress+Hauser’s Proline 400 transmitter to provide a complete fl ow metering solution. For decades, users in many process industries have turned to ultrasonic clamp-on instruments for convenient fl ow measurement. This trend continues, but with growing requirements for instrument data. Prosonic Flow W 400 addresses this and other issues by providing reliable measurements of process parameters, along with a host of additional information. The fl owmeter uses a nonintrusive, clamp-on measurement method, with its ultrasonic sensors mounted directly on a pipe’s exterior. This provides safe measurement of many fl uids, independent of their conductivity or other properties. This includes corrosive, abrasive, and toxic fl uids, making this fl owmeter ideal for monitoring countless processes.


Because neither piping nor process fl ow are interrupted, clamp-on fl owmeters can be easily used for retrofi tting at any time. They are suitable for low- or high-pressure applications, on pipes smaller than an inch in diameter, and up to 160 inches, such as those encountered in water distribution. This size range illustrates the Prosonic Flow W 400 measurement solution’s versatility. It can be used to measure fl ow, monitor processes, verify previously installed fl owmeters, detect leaks in a pipeline, and for other applications.


The fl owmeter’s IP68 Type 6P submergence-rated ultrasonic sensors provide long-term and reliable operation, requiring little maintenance. This makes them suitable for use in harsh process and ambient conditions, able to withstand temperatures from –40 to +266 °F. The Proline 400 transmitter includes a built-in web server, so users can access process, diagnostic, confi guration, and other instrument data via any device capable of hosting a web browser, such as a laptop, smartphone, or tablet. The transmitter provides targeted parameterization of measuring points, and it saves time during commissioning, maintenance, and service. Its LCD display and web-based operating tool each show real-time measurement quality—good, acceptable, or bad—to provide key status information at a glance.


Piping systems in the process industry often have multiple fi ttings and elbows that disturb the fl ow profi le and, along with it, the accuracy of ultrasonic fl ow measurement. The Prosonic Flow W 400 solution is optionally available with Endress+Hauser’s FlowDC function, which detects and corrects for the effects of fl ow disturbance. This ensures measurement accuracy even in the presence of a short pipe inlet run, for example when signifi cantly reduced from the standard 15 pipe diameters down to two. The FlowDC function increases fl exibility for equipping new or retrofi tted systems with clamp-on fl owmeters.


Heartbeat Technology—a testing function integrated into all Endress+Hauser Proline measuring devices—provides instrumentation self-diagnostics, along with traceable measurement verifi cation during operation. This technology monitors for changes to the instrument electronics and sensors caused by extreme environmental or process conditions, increasing measurement integrity.


Prosonic Flow W 400 can be mounted on a wide variety of pipe types and materials with or without lining, including metal—e.g., steel or cast iron—plastic, glass-fi ber-reinforced plastic, and composite materials. A maintenance-free contact medium, called a coupling pad, provides optimum sound transmission between sensor surface and the pipe, and the resulting high signal strength ensures stable measurement results and long-term reliability. These clamp-on fl ow sensors are available in multiple ultrasonic frequencies ranging from 0.3 to 5 MHz, optimized for application pipe size, pipe material, and fl uid.


Rivers urgently need clean up to protect biodiversity and health

“The report concludes that the current situation has been driven by under-funding, under-regulation, under-reporting, insuffi cient monitoring and enforcement, and a lack of strong environmental leadership and policy development from Westminster.”

Dr Arnot adds: “The river water quality challenge is extremely complex and involves multiple stakeholders. The biggest contributors of pollutants are the agriculture sector and the water companies, but industrial manufacturing, runoff from the transport network, and use of pharmaceutical and cleaning chemicals also release emerging contaminants. Public behaviours including fl ushing wet wipes and cooking oils, as well as general littering, contribute to the problem as well.”


“Finding solutions to these problems will require effective collaboration across this wide range of stakeholders. We must fi nd ways of getting government, the regulators, landowners and the farming community, water companies, manufacturers, urban planners, and the public to come together in a co-ordinated, well-funded, well monitored way, with strong policy, regulation, and enforcement.”


Research being conducted within WIRC supports these challenges. Current research spans several themes, including reducing water consumption in domestic and industrial systems, designing and evaluating rainwater capture technologies for new developments, modelling the performance of the sewer network and the transport of pollutants in rivers, and delivering opportunities such as tracking the spread of Covid-19 and other public health indicators through wastewater-based epidemiology.

Members of Bath’s Water Innovation & Research Centre (WIRC) say that release of the Environmental Audit Committee Report on Water Quality in Rivers should be a wake-up call to lawmakers, regulators, various industry sectors, and the public. Dr Tom Arnot, Co-Director of WIRC, says that the report highlights a lack of co-ordination and investment in protecting our river systems: “The current state of our rivers arises due to a weak legislative landscape which has led to sewage overspills, run-off of farm slurries and fertilisers, combined sewer overfl ows, and release of microplastics and other contaminants into the UK river system, putting human and environmental health at risk, and signifi cantly damaging biodiversity.
