Aldex C-800 Water Softening Resin – NSF 44 & 61 Certified High Capacity Cation Resin (Sodium Form)

High-Capacity, NSF Certified Water Softening Resin for Reliable Performance

The Aldex C-800 Water Softening Resin is a premium-grade, gel-type strong acid cation resin engineered for consistent, high-efficiency water softening across residential, commercial, and industrial applications. Supplied in the sodium (Na⁺) form, this resin effectively removes hardness minerals such as calcium and magnesium, delivering reliable soft water performance.

Tested and certified under the WQA Gold Seal program, Aldex C-800 meets NSF/ANSI/CAN 61 & 372, NSF/ANSI 44, and CSA B483.1 standards, ensuring safe use in potable water systems.

Manufactured without chlorinated solvents, this resin offers extremely low TOC leakage, along with no taste, odor, or color contribution to treated water.

Key Features

• NSF/ANSI 44, 61, 372 & CSA B483.1 certified
• High capacity cation resin for efficient hardness removal
• Supplied in sodium (Na⁺) form – ready for use
• No chlorinated solvents → low TOC and cleaner output
• No taste, odor, or color contribution
• Strong, durable bead structure for long service life
• Proven performance with 40+ years of field use
• Suitable for residential, commercial, and industrial systems

Core Specifications

Performance & Capacity

• Total Exchange Capacity: ≥ 1.9 meq/mL
• Capacity Rating:
  • ~30,000 grains/cu. ft. (15 lbs salt regeneration)
  • ~20,000 grains/cu. ft. (6 lbs salt regeneration)

This delivers high efficiency with reduced salt consumption, lowering operating costs over time.

Operating Conditions

Regeneration Guidelines

• Dosage: 2 – 15 lbs salt per cu. ft.
• Contact Time: 15 – 60 minutes
• Slow Rinse: 20 gallons per cu. ft.
• Fast Rinse: 30 gallons per cu. ft.

Designed for efficient regeneration and consistent performance across cycles.

Why Aldex C-800 Stands Out

This isn’t a commodity resin—it’s built for reliability.

• High capacity output → fewer regenerations
• Low TOC leakage → cleaner treated water
• Durable bead structure → longer service life
• Field-proven performance → trusted across thousands of installations

Bottom line: consistent results, lower operating cost, longer lifespan.

Typical Applications

• Residential water softeners
• Commercial and institutional systems
• Industrial water softening
• Farm and agricultural systems
• Pre-treatment for filtration and process systems

Operational Insights

• Capable of removing most dissolved iron, though periodic cleaning may be required in high iron conditions
• Chlorine exposure should be kept below 1.0 ppm to prevent long-term resin degradation
• Backwashing should expand the bed by ~50% to maintain performance and remove solids

Frequently Asked Questions (FAQs)

Is this resin safe for drinking water systems?

Yes. It is fully certified under NSF and CSA standards for potable water use.

What size systems is this suitable for?

Everything from residential softeners to large industrial systems.

Can this remove iron?

It can remove some dissolved and suspended iron, but additional treatment may be required for high iron levels.

What regenerant should I use?

Sodium chloride (salt) is standard, but potassium chloride can also be used.

How long does this resin last?

With proper maintenance, it delivers long service life due to strong bead durability.
