Two Bed Deionization System

~ (Carbon Steel Vessel):

Two Bed Deionization System consists of two separate columns each containing different type of resins. The first column usually contains cation resins while the second column in series contains anion resins. The two resin columns work together to remove cations and anions from the feed water. The effluent quality from a typical Two Bed DI System can reach 1 Mohm-cm. Two Bed DI System can either be placed downstream of a Reverse Osmosis (RO) System to increase the quality of the RO permeate or be used without the RO System. In the latter case, the service life of the Two Bed DI system is only about one twentieth of that of the former.

Benefits :

• Two Bed DI System is low in capital cost and simpler in operation when compared with other DI Systems, such as Multistep DI and Mixed Bed DI. If You are not demanding Multi-Megohm water, Two Bed DI System is the technology of choice.

Standard Features :

• Rubber lined carbon steel vessels designed for 7 bar working pressure.
• Sight glass to permit visual inspection of resin level and backwash flow.
• PVC SCH 80 face piping and valves.
• Separate regeneration distributors for efficient distribution of regenerant flow.
• Flow controllers for backwash flow rate control.
• PVC Pneumatic Control valves.
• Feed water rotameter.
• Regeneration flow rotameters.
• Inlet and Outlet pressure gauges.
• PVC eductors for regenerant introduction.
• Sampling ports for acid and caustic concentration.
• Sampling cylinders for non-hazardous sampling.
• Programmable Logic Controller.
• NEMA 4X Control panel for electrical and solenoid valves.
• Indicator lights to show each regeneration step.
• Automatic and manual step through of each regeneration steps.

Optional Features :

• Electronic flow meter (Optional)
• Circulation pump (Optional) Manual regeneration versions are also available at a lower price.
• Valve size up to 2” will be pneumatic diaphragm valves with limit stop and manual override.
• Valve size larger than 2” will be pneumatic butterfly valves.
• Strong acid cation and type 1 strong base anion exchange resins as standard, can be used with other combinations of resins to suit different applications.
