The Raw Water Filtration module houses the Raw Water vessel, two independent sand filters and Filtered Water vessel. The degassed liquid is then pumped forward through the Anion Bed. The Cation Bed and Anion Bed require a regenerating every 5hours to maintain the optimum condition of the resins. Water from the Filtered water vessel is pumped forward through the Cation vessel; this then enters the degasser vessel after experiencing a carbonate removal process. Within the Acid Dosing vessel is a 5% dilution of Hydrochloric Acid, which is used to regenerate the Cation Bed. Mains water is transferred into the raw water vessel, which is then pump forward through either one of the sand filters into the filtered water vessel. On the Dosing module there is a an acid dosing vessel, caustic dosing vessel, Cation Bed, Anion Bed and Degasser vessel. In the Caustic Dosing vessel is a 4% dilution of Sodium Hydroxide; this is used to regenerate the Anion Bed.

Temperature, level, flow and conductivity control loops can be implemented
Manual control, single feedback loops, through to sophisticated cascade loops and distributed supervisory control of the whole process by a remotely located computer can be demonstrated
The effect of dead time and heat recycle can be demonstrated
A bench mounted process plant trainer with multiple streams both interacting and noninteracting. The process plant incorporates a miniature three-stage plate heat exchanger heated from a hot water circulator, two independent feed tanks, a holding tube with product divert valve and two variable-speed peristaltic pumps
An electrical console provides measurement and control of the process plant and enables a variety of control techniques including manual operation, on/off control, control from an external signal and control from a PC or PLC
The equipment incorporates electrical fault simulation and control, data logging software, and a USB computer interface.
Features:
Multiple inputs, multiple sensors, multiple control strategies
Operational sequencing, including startup and shutdown
Recycle implications on process control
Effects of dead time
Manual control, single feedback loops, through to sophisticated cascade loops
Temperature, level, flow and conductivity control loops can be implemented.
