Water that meets spec — serviced or owned.
WaterX Treatment Company delivers ion-exchange tanks and systems for softening, demineralization, metal recovery, and selective contaminant removal. Run it as a service — we pick the resin, swap it before breakthrough, and regenerate it offsite — or have us engineer and build a system you own outright. Either way, you stay on spec and under your limits.
One partner for every ion-exchange job on your site.
From bulk hardness to a single trace contaminant, we match the chemistry to the problem — so you only pay to remove what actually matters to your process and your permit.
Water softening
Strip calcium and magnesium with sodium-form cation resin and stop scale before it starts — lower energy bills, fewer breakdowns, and longer life for boilers, cooling towers, RO membranes, and process equipment.
Learn more → Chlorine / chloramineDechlorination (GAC)
Granular activated carbon tanks strip free chlorine and chloramine before they reach your resin or RO membranes — the pretreatment that protects everything downstream, and knocks back taste, odor, and organics while it\'s at it.
Learn more → TDS / AlkalinityDemineralization & dealkalization
Two-bed cation/anion demin for low-conductivity process water, or dealkalization to strip bicarbonate for boiler makeup — sized so you get the purity your process needs without paying for ultrapure you don't.
Learn more → MetalsMetal finishing & recovery
Recover drag-out, recycle rinse water, and pull nickel, copper, zinc, and chromium from plating lines with chelating and strong-base resins. Recovery that pays you back — lower metal purchases and less to discharge.
Learn more →Selective contaminant removal
Remove the one ion that's failing your tests — nitrate, hexavalent chromium, perchlorate, boron, arsenic, uranium — without the cost of stripping everything else. Targeted resins for a specific problem.
Wastewater & compliance
Chelating resins polish heavy metals to permit limits before discharge — the last step that keeps you inside your NPDES or sewer limits and off the regulator's radar.
Process & specialty duties
Decolorization, deashing, condensate and catalyst service, and food & beverage demineralization — wherever a purpose-chosen resin does the separation better than anything else.
Acid purification & recovery
Acid-retardation resins pull free acid back out of spent pickling, anodizing, and plating baths — returning usable acid to the line and shrinking your neutralization chemistry and hazardous-waste bill.
PFAS removal
Get ahead of tightening PFAS limits. Single-use selective resins capture PFOA, PFOS, and short-chain PFAS to detection limits — and we handle media changeout and certified disposal, so it stays off your plate.
Metal scavenging
Thiol and chelating scavenger resins polish trace mercury, lead, cadmium, and residual heavy metals to parts-per-billion — the step that finally gets a stubborn stream under a tight limit when nothing else will.
What you want gone decides the chemistry.
Ion exchange isn't one resin — it's a toolkit. We match the bed to the target so you remove the problem ion without paying to remove the rest.
| Target | Resin chemistry | Where it's used |
|---|---|---|
| Ca²⁺ / Mg²⁺ (hardness) | Strong-acid cation, Na⁺ form | Softening, scale & membrane protection |
| Free chlorine / chloramine | Granular activated carbon (GAC) | Dechlorination; RO & IX pretreatment |
| Alkalinity (HCO₃⁻) | Weak-base anion / dealkalizer | Boiler feed, pH and conductivity control |
| All dissolved ions (TDS) | Cation + anion, two-bed or mixed | Demineralized process water |
| Hexavalent chromium (CrO₄²⁻) | Strong-base anion | Plating, groundwater remediation |
| Nitrate (NO₃⁻) | Nitrate-selective strong-base anion | Drinking water, agricultural runoff |
| Heavy metals (Ni, Cu, Zn, Pb) | Chelating (iminodiacetic) | Metal finishing, discharge compliance |
| Boron / arsenic / uranium | Selective specialty resin | Groundwater and well-water treatment |
| Free acid (HCl / H₂SO₄) | Acid-retardation resin | Spent pickling & anodizing baths |
| PFAS (PFOA / PFOS) | Single-use selective anion | Groundwater, landfill & process water |
| Trace Hg / Pb / Cd | Thiol / chelating scavenger | Final discharge polishing to ppb |
A serviced loop — or a system of your own.
Prefer not to own anything? With our serviced model you never buy equipment, pull a permit, or store acid and caustic — the resin cycles between your site and our regeneration line, and we own the chemistry, the regeneration, and the schedule. Prefer to own it? We'll engineer and build the same system for you to run in-house. The steps below describe the serviced loop.
Charged → exhausted → regenerated → chargedSpecify
We pick the resin and configuration for your target, flow, and feed quality.
Deliver
Charged exchange tanks or a skidded system arrive on a route you set.
Run
Water passes through the bed; the target ions are exchanged out to spec.
Monitor
Hardness, conductivity, or metal levels are tracked toward exhaustion.
Exchange
Spent tanks are swapped before breakthrough — no interruption to your line.
Regenerate
Resin is recharged offsite and returned to the route, ready to run again.
The tanks that show up at your door.
From a single charged cylinder to a pre-plumbed duplex skid — we either own the vessels and swap them on a schedule, or engineer and build the same system for you to own outright.
Sized to your stream, not a catalog.
Standard exchange-tank and skid sizes. Final selection is matched to your flow, feed chemistry, and target outlet.
| Configuration | Resin volume | Typical flow | Primary duty |
|---|---|---|---|
| Softener tanks | 0.5 – 7 ft³ | 2 – 40 gpm | Hardness to <1 ppm |
| Two-bed demineralizer | 1 – 10 ft³ each | 5 – 50 gpm | Low-conductivity process water |
| Dealkalizer | configurable | 5 – 40 gpm | Alkalinity reduction for boilers |
| Chelating metal-removal | configurable | 2 – 30 gpm | Heavy metals to permit limit |
| Selective bed (NO₃ / Cr) | configurable | 5 – 50 gpm | Single-ion targeting |
Figures are representative ranges for planning — share your stream and we'll size the exact bed.
The regenerant waste never becomes your problem.
Resin is regenerated offsite with acid, caustic, or brine at a properly equipped facility. The spent regenerant — and any metals it carries — stays in our hands, not in your sewer and not on your discharge report.
- Offsite regeneration — no acid, caustic, or brine stored at your site
- Spent regenerant and captured metals handled to California standards
- No regeneration permit or neutralization system for you to maintain
- Documentation that keeps your water program audit-ready
