The Computer Controlled Reverse Osmosis/Ultrafiltration Unit, "ROUC", allows the practical study of the ultrafiltration and reverse osmosis techniques.
The Computer Controlled Reverse Osmosis/Ultrafiltration Unit, "ROUC", performs a tangential flow filtration process, which is a system that prevents the formation of impurities sediments that reduces its capacity.
Two variable of the effluent must be known to perform reverse osmosis and ultrafiltration separation practical exercises:
A computer controlled three piston positive displacement pump impels the effluent to the membranes. The motor of the pump is controlled by a variable frequency drive for obtaining different flows in function of the required separation process. As it is a positive displacement pump the flow obtained will be directly proportional to the motor speed.
The pump supplies the effluent to both tubular membranes connected in series and lodged in a membrane module. The solution to be treated flows inside the tubes, the permeate flows radially from the inside to the outside of the tubes and the waste is obtained at the end ofthe tubes.
The effluent impelled by the pump will receive heat from it, increasing its temperature. The permeate will be collected in a final product tank. The concentrate will go back to the initial tank to be treated again as effluent, but due to the temperature rise this concentrate will flow through a plate heat exchanger.Membranes with different weight cut-off points are included. They only differ in length and number from the ones installed in a real plant.
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
