Bürkert produces components for the measurement, instrumentation and control of gases and liquids. Bürkert experts have designed a reverse osmosis skid for water desalination using Bürkert products. This system was introduced at IFAT Munich.
The reverse osmosis system is ideal for desalination of industrial process water and drinking water. The demo system consists of a water circulation system for desalination of softened water.
In the system, permeate and condensate are pumped into a common collecting tank and later removed as raw water. The water first passes through a 20” fine filter with a 5 µm filter cartridge, and then desalinated in three membrane modules. A centrifugal pump with a frequency converter functions as a high-pressure pump, and an energy-efficient circulating pump with a frequency converter circulates the water. An ultra-quiet compressor provides the control air for the pneumatic valves. To better illustrate the single volume flows, Bürkert chose rotameters, which are standard components in water treatment systems. The flow rate is measured by the paddle wheel flow meters, and is sent to the controller. The input pressure and system pressure is monitored by pressure switches.
