Ultrasonic level
Ametek Drexelbrook has launched a new family of ultrasonic devices -- the IntelliScan™ and UniScan™ non-contact, ultrasonic level measurement instruments. The units deliver radar-like performance at an ultrasonic price and have the flexibility to measure liquids, solids and open channel flow. The UniScan also has the added benefit of being a 2-wire, intrinsically safe design. The instruments self adjust to virtually all types of conditions and environments and feature automatic ambient temperature adjustment. The same instrument can be used to measure liquids, solids, granular, slurry or open channel flow without needing to change the lightweight transducer. The units can provide accurate measurements (0.25% of measured distance) while automatically compensating for changes in ambient temperature and other variable environmental conditions.

Electrodeionization system
The Omexell™ EDI system uses a spiral-wound membrane that is sealed in a high strength FRP pressure vessel to optimize performance and maintain continuous product quality while eliminating the need for chemical regeneration. EDI is typically used to polish RO permeate and the module can produce up to 18+ MW-cm high-purity water with high silica and boron rejection. The modules are leak-free, fully serviceable, more resistant to hardness scaling, and require less energy consumption than conventional EDI devices.

Scale control
HRT Power provides a pulsed-power system for biological and scaling control. It is well established in water treatment that coagulation and calcium carbonate precipitation will result in microbial reduction. Under pulsed-power treatment, precipitation occurs in the bulk solution as a powder. These growing particles incorporate microbes and limit their growth. The cooling tower device uses coils to induce pulsed electric fields in the recirculating water. An adaptation of this technique, The Dolphin System™, which is being used on the open loop of cooling towers in many parts of the country, is offered as an integral part of the company's combustion turbine performance enhancement system.
