Product Description

The Wattech 'WSB' Series Automatic Separate-Bed Deionizer (DI) systems are engineered to economically produce high purity water through the removal of total dissolved solids (TDS). Each WSB system is constructed using robust, industrial-grade components and materials for reliable operation and exceptional performance.

Features/Benefits

• Heavy-gauge carbon steel pressure vessels internally lined with a chemically resistant vinylester coating. All exterior surfaces are coated with a acid and caustic resistant "Safety Blue" paint finish. Non-ASME construction with 100 psig working pressure.
• Flat-false bottom resin support with a hub-radial, non-clogging underdrain constructed of PVC for the ultimate in corrosion resistance.
• High capacity, strong-acid cation exchange resin in hydrogen-form.
• High capacity, Type 2 strong-base anion exchange resin in hydroxide-from (shipped in chloride form).
• Sch 80 PVC face-piping assemblies with thermo-plastic, normally-open, "Y" pattern diaphragm control valves. Vessels with service piping 4" and larger utilize Sch 80 PVC face-piping and double-acting butterfly control valves. All control valves are air-operated requiring a 80-100 psig of clean, plant air supply.
• Cation and anion vessels are mounted on a structural carbon steel skid and pre-piped to the fullest extent for minimal floor space requirements and ease of installation.
• Comprehensive Programmable Logic Controller (PLC) system pre-wired in a NEMA-4X electrical enclosure. Includes all operator switches, push-buttons, indicator/alarm lights, and heavy-duty solenoids for control valve actuation.
• Panel-mounted system flow meter and DI water conductivity monitor with digital display.
• Pre-assembled system pressure gauge and sampling valve center.

Optional Equipment

• ASME constructed, stamped, and certified pressure vessels for varying working pressures.
• Automatic low/no flow recirculation pump systems.
• Automatic alternating systems for continuous service.
• Sulfuric acid regenerated cation systems.
• Pumped chemical regeneration systems.
• Fiberglass reinforced plastic (FRP) skids and pressure vessels (48" diameter and under).
• Rubber-lined pressure vessels.
• Instrumentation additions include flow totalization, pH, and chemical percent meters.
• Touch-screen operator interface terminals in lieu of lights and switches.
• Forced-draft decarbonator towers for CO2 reduction prior to anion vessel.
• Product water storage tanks and re-pressurization pump systems.
• Waste chemical neutralization systems with automatic controls.
• Multi-media, activated carbon, and reverse osmosis pre-treatment systems.
• Mixed-bed deionization and UV sterilization post-treatment systems.
