Bürkert built a reverse osmosis system suitable for desalination of industrial process water and drinking water. The transportable device serves as a demonstration unit for the company’s capabilities and will be displayed at tradeshows.

Constructed with Bürkert products, the skid-mounted unit consists of a water circulation system for desalination of softened water. Permeate and condensate are pumped into a common collecting tank, from which they are later removed as raw water. The water first passes through a 20" fine filter and then it is desalinated in three membrane modules. A centrifugal pump with a frequency converter functions as a high pressure pump, and a circulating pump with a frequency converter circulates the water. An ultra-quiet compressor provides the control air for the pneumatic valves.

Bürkert chose rotameters to illustrate the single-volume flows. Paddle-wheel flowmeters measure the flow rates and send them to the controllers, and pressure switches monitor the input pressure and system pressure.

The company is not planning to include reverse osmosis skids in its product range. The system is intended as a demonstration of Bürkert’s capabilities.
