Product Water Treatment

Ion Exchange Resin (Anion)

High-performance anion exchange media for demineralization, silica reduction, nitrate removal, and DI polishing. Available as Strong Base Anion (SBA Type I / Type II) and Weak Base Anion (WBA) grades.

SBA Type I / Type II options WBA for demin + organic load Chloride or hydroxide form DI & mixed-bed compatible
Packaging: 25 L bags / 200 L drums / 1 m³ supersacks (as applicable)
Documentation: SDS • COA • TDS (on request)
Selection support: share feed water & targets for correct grade

What it does

Anion exchange resins remove negatively charged ions (anions) from water. In demineralization trains, anion resin typically follows a cation exchanger to remove species such as chlorides, sulfates, nitrates, bicarbonate/alkalinity, silica, and dissolved CO2 (depending on the system design and resin type).

Target use
DI water / polishing
Key removals
Anions, silica, nitrate
Common trains
SAC → SBA, or mixed-bed
Selection matters: SBA Type I is typically preferred for higher silica polishing and stronger base anion removal, while Type II can offer efficiency advantages in many general demin applications. WBA grades are often used when higher organic loading is present or when removing strong mineral acids after cation exchange (system dependent).

Applications

Common use cases across industrial and utility water systems (final spec depends on targets and feed water).

  • Two-bed demineralization (cation → anion) for boiler feed and process water
  • Mixed-bed polishing (with cation resin) to achieve high resistivity DI water
  • Silica reduction / polishing steps for high-pressure boiler requirements
  • Nitrate and sulfate reduction in industrial water preparation (system dependent)
  • Condensate polishing (where applicable) and critical rinse-water preparation
Integration note: Upstream pretreatment (filtration, carbon, antiscalant/RO, and proper cation exchange) improves cycle length and protects resin capacity from organics, iron, and suspended solids.

Quality & documentation

Strong Base Anion (Type I)

Quaternary ammonium functional groups designed for strong anion removal and commonly preferred where silica polishing and high-purity requirements are critical (system dependent).

  • Demin + high-purity polishing trains
  • Often selected for lower silica leakage targets

Strong Base Anion (Type II)

Similar base functionality with efficiency advantages in many general demin applications. Performance depends on feed composition, operating temperature, and regeneration practice.

  • General DI water production
  • Often attractive for balanced cost/performance

Weak Base Anion (WBA)

Used to remove strong mineral acids after cation exchange in certain system designs and can be helpful under higher organic load conditions (application dependent). Typically regenerated with caustic.

  • Specific demin configurations & organic considerations
  • Supports lower chemical usage in some trains

Need a tighter spec? We can align offers to typical procurement parameters: capacity, moisture content, particle size range, uniformity coefficient, max operating temperature, and compliance requirements.
Parameter Typical range / note (indicative)
Resin type SBA Type I / SBA Type II / WBA (state your preference or request recommendation)
Form supplied Cl⁻ standard; OH⁻ on request (common for polishing / mixed-bed service)
Moisture content Wet shipped; typical commercial ranges depend on matrix and type (confirm on COA/TDS)
Particle size Typical industrial bead ranges; request uniform grade if pressure drop or kinetics are critical
Operating pH Broad operating window for most anion resins; verify against your chemicals and temperature
Max operating temperature Depends strongly on resin chemistry (Type I/II/WBA) and form; confirm for hot service
Packaging 25 L bags, 200 L drums, 1 m³ supersacks (as applicable to lane and destination)

The table above is intentionally indicative. For correct selection, share your feed water analysis and target quality; we’ll quote the appropriate resin grade and verified parameters.

Operating & design guidance

Performance depends on exchange capacity, resin type, regeneration quality, and pretreatment. These guidance notes help you provide the right inputs for selection and procurement.

Cycle length

Driven by feed TDS profile (especially sulfate/nitrate/alkalinity), leakage limits, and how completely regeneration restores capacity.

Pressure drop

Influenced by bead size, bed depth, flow rate, and fouling. Provide vessel dimensions and service flow to align the bead distribution.

Fouling control

Upstream filtration and organics control reduce irreversible capacity loss. Share iron, organics/TOC, and turbidity if available.

Pro tip for procurement: If you can provide your service flow (m³/h), bed volume (L), and target leakage (conductivity/silica), we can propose a resin type and bead grade that fits both quality and hydraulic constraints.

Quality, documentation & commissioning support

We supply documentation and practical support for smooth acceptance and start-up.

Documentation pack

SDS, COA, TDS; plus packing list, origin docs, and compliance declarations where required.

Batch consistency

Specification alignment with procurement limits for capacity, moisture, and bead grading (by offer).

Start-up guidance

Support for initial rinse/conditioning steps and best-practice checks after loading.

Commercial note: Resin is typically sold on a wet-liter basis. For repeat orders, we can lock a consistent grade and packaging format to make maintenance cycles and inventory planning easier.

FAQ

Fast answers to common procurement and technical questions.

Academy

Do you supply Type I and Type II SBA resins?

Yes—availability depends on lane and packaging. Share your silica and conductivity targets for the correct recommendation.

Cl⁻ form vs OH⁻ form—what should I order?

Cl⁻ is common for general supply and commissioning; OH⁻ is often requested for polishing/mixed-bed duties. Your system design governs the choice.

What causes early leakage or short cycles?

Common drivers include incomplete regeneration, fouling (iron/organics), channeling, excessive service flow, or resin aging. Share symptoms and operating data for support.

Can you match an existing brand/spec?

Yes. Provide your current resin name, type, form, bead size, and any COA/TDS you have. We’ll propose an equivalent lane.

What packaging is best for maintenance teams?

25 L bags suit smaller systems and staged loading; 200 L drums and 1 m³ supersacks are efficient for larger plants. Tell us your handling constraints.

Can you support pilot trials?

Where feasible, yes—ask for sample options and share your trial objectives, flow, and monitoring plan.
