A novel spacer technology for RO membrane elements
This company’s reverse-osmosis (RO) elements (photo) use a unique Printed Spacer Technology that improves the performance of systems with just the change of the membrane element. The technology replaces mesh spacers that have been used for decades with printed features on the membrane surface, improving the flow of water through the membrane element. Printed spacers open the feed channel inside of the element by using far less material. This results in superior spiral-wound membrane performance, improving system output, element life and energy usage, says the company. In addition to improved operations, customers also enjoy lowered operating costs and support meeting sustainability goals. The BW product line has two feed-spacer options: ECO, designed to save up to 60% of wasted energy, especially suitable for companies with challenging feedwater or those looking for ways to save on electricity costs and achieve their ESG goals; and FLO, which optimizes output by taking full advantage of the more than 500 ft2 of membrane surface. This configuration is ideal for applications where a system is struggling to keep up with demand, has limited space for a water treatment system, or is only operated for a short period of time. — Aqua Membranes, Albuquerque, N.M.

This three-way ball sector valve (photo) — said to be the world’s first — achieves high volumetric flowrates that are virtually identical in all directions. The company’s approach of using the ball sector design for three-way valves is said to be completely new, and achieves about 20% higher Kvs values than three-way valves with a conventional design. These high flowrates are achieved through the special design of the ball sector and the valve body. The resulting straight flow in one direction and the minimized flow deflection in the other result in the very high and almost identical Kvs values. Superior control accuracy is ensured by the optimized contour of the ball sector and its backlash-free bearing, together with the actuator and positioner. The positioning angle of 90 deg enables a very large control range to be achieved. The rangeability is 300:1. — Schubert & Salzer Control Systems GmbH, Ingolstadt, Germany

This new state-of-the-art hybrid cooling system (photo) is designed to deliver exceptional thermal performance while minimizing environmental impact. The system offers a perfect balance between water and energy consumption while setting a new standard in the heat-rejection industry. Designed to bridge the gap between standard adiabatic coolers and cooling towers, the hybrid offers two cooling modes: dry and wet. In dry mode, heat is exchanged with ambient air via its sensible enthalpy. For wet mode, the system waters the coil and uses both the water-sensible and latent enthalpy via an adiabatic effect where air evaporates the water. This allows the system to work with ambient dry-bulb temperatures well above process-fluid outlet temperatures. — Kelvion Holding GmbH, Herne, Germany
