ResinTech CGS is a residential grade strong acid cation resin in sodium form, made from standard cross-linked gel. It is optimized for regeneration efficiency and high capacity.

Applications

• Softening - Residential

CGS is intended for residential water softening of waters that do not contain significant chlorine residual and where potable water certification is required.

Certifications

• WQA Gold Seal (NSF/ANSI/CAN 61: Drinking Water System Components - Health Effects)
• Kosher Certified
• Halal Certified
• FDA Compliance (Paragraph 21CFR173.25 of the Food Additives Regulations of the US FDA)

Physical and Chemical Properties

• Particle Size: 16 to 50 US Mesh (297 - 1190 μm)
• % < 50 mesh (300µm): < 1%
• Minimum Sphericity: 90%
• Uniformity Coefficient: 1.6
• Reversible Swelling (Na to Ca): -5% to -3%
• Capacity (meq/mL): 1.9
• Moisture Retention: 40% to 52%
• Shipping Weight: 49 - 51 lbs/ft³ (785 - 817 g/L)
• Regenerability: Yes

Operating Limits

• Maximum continuous temperature (Sodium form): 250°F (121°C)
• Operating pH range: 0 to 14 SU

CGS has marginal resistance to chlorine and other oxidants and is not ideal for high temperature and other high stress applications.

• Backwash expansion: 25 to 50 percent
• Maximum pressure loss: 25 psi
• Regenerant Concentration (Salt cycle): 10 to 15 percent NaCl
• Regenerant level: 4 to 15 lbs./cu.ft.
• Regenerant flow rate: 0.5 to 1.5 gpm/cu.ft.
• Regenerant contact time: >20 minutes
• Displacement flow rate: Same as dilution water
• Displacement volume: 10 to 15 gallons/cu.ft.
• Rinse flow rate: Same as service flow
• Rinse volume: 35 to 60 gallons/cu.ft.
• Service flow rate: 1 to 10 gpm/cu.ft.

Packaging Options

• 1 ft³ bags
• 1 ft³ boxes
• 1 ft³ drums
• 7 ft³ drums
• 42 ft³ supersacks

Technical Data

Capacity and leakage data are based on the following: 2:1 Ca:Mg ratio, 500 ppm TDS as CaCO₃, 0.2% hardness in the salt and 10% brine concentration applied co-currently through the resin over 30 minutes. No engineering downgrade has been applied.

Backwash expansion and pressure loss data are presented graphically, with values for expansion in % and pressure loss in psi/ft. of Resin, as a function of flow rate (gpm/sq.ft.) and temperature (°F).

Softening capacity data is presented graphically, showing Kilograins per cu. ft. as a function of Salt Dose in lbs per cu. ft. for various flow rates (gpm/sq.ft.) and temperatures (°F).
