Careful management of water and wastewater systems on industrial and utility sites is essential in ensuring environmental compliance, staff safety, and mitigating reputational and financial risk. Dosing pump failure, and even routine maintenance of equipment, can put systems out of service for significant periods and draw operatives away from other critical work.
Join industry and engineering specialists as they discuss technology developments in chemical metering. Hear about real-world applications where longer service life has been designed into the latest equipment and find out how future developments could overcome your water system challenges.
Key discussion points
The panel consists of engineering professionals and water treatment specialists from Vessco and WMFTS, including:
Increasing regulatory compliance in water and wastewater management, coupled with staffing challenges, requires investment in technology to help meet current and future requirements for environmental compliance and staff safety, as well as for mitigating reputational and financial risk. Dosing pump failure can have a significant negative impact on compliance, staffing, and operations.
Watson-Marlow Fluid Technology Solutions (WMFTS) developed the Qdos peristaltic pump to address these challenges. With their latest Qdos® CWT™ model, pumphead life is extended by up to four times as long as traditional pumps. Easily changeable pumpheads reduce labor and maintenance costs, and safety features built into the pump lower compliance violation risk.

Die swell has been used as a qualitative measure of polymer melt elasticity for quality control purposes in plastics industry. Die swell also can be used for analysis of extrudate smoothness in an extrusion process.
Die swell is expansion of extrudate after exiting the die. It happens as a result of the molecular orientation that is generated by the flow in the die (with the greatest extension occurring near the wall) and recoiling after exiting the die (contracting in the flow direction and expanding in directions perpendicular to the flow). In other words, this phenomenon is produced by plastic materials memory. As the extrudate exits the die, it tries to return to its initial molecular coil shape.
Dynisco LCR capillary rheometer is able to measure the diameter of the extrudates using a CCD element detection and laser beam. This accessory element has the following specification: light source of 800 nm laser, resolution of 2.75 µm, measuring range of 0.13-23 mm, response time of 1.4 ms, and accuracy of +/- 0.003 mm.
The most common purpose of agitation in biopharmaceutical processing is liquid/liquid and solid/liquid blend (solutions and suspensions). Agitators are performing their duty while submerged in a fluid phase, and consequently designed for this intended use, considering that running in air would not fit any purpose. This article discusses different bearing designs and materials of construction typically available.
