RO Membranes Built for Your Industry

8-inch RO elements typically ship on 8–16 week factory lead times. We stock NanoH2O (formerly LG Chem) NanoH2O brackish and seawater membranes in the US and ship the same day — so a failed element is a same-day fix, not a quarter-long outage. Here's where our customers put them to work.

Outpatient Dialysis Clinics

Hemodialysis demands AAMI/CMS-compliant ultrapure water. A membrane that drifts out of spec is a patient-safety event, not a maintenance ticket — so clinics can't wait weeks for a replacement element.

Common applications

  • AAMI RD62 water treatment
  • Hemodialysis feedwater pretreatment
  • TDS & contaminant rejection
  • Emergency element replacement
Recommended: NanoH2O BW 400 R G2 — high rejection

Craft Breweries

Brewing water is recipe. Dialing in a mineral profile starts by stripping source water to a clean baseline, then building it back to style. A fouled element mid-run costs tank turns and shelf slots.

Common applications

  • Brewing liquor baseline
  • Water profile control
  • Dealkalization
  • Seasonal capacity spikes
Recommended: NanoH2O BW 400 ES — low-energy brackish

Bottled Water Plants

24/7 duty cycles and FDA CGMP tolerances mean a rejection or pressure-drop excursion halts shipping. High-output elements from US stock keep lines running instead of idle.

Common applications

  • Purified & spring water production
  • FDA CGMP process water
  • High-recovery multi-stage arrays
  • Continuous 24/7 operation
Recommended: NanoH2O BW 440 R G2 — high output

Dairy & Food Processing

Whey concentration and CIP water foul membranes aggressively, driving short cycles. With plant downtime at $10k–$50k/hour, same-day replacement stock is the difference between a hiccup and a shutdown.

Common applications

  • Whey & milk concentration
  • Clean-in-place (CIP) water
  • Ingredient water
  • Process water reuse
Recommended: NanoH2O BW 440 R G2 — high area

Commercial Car Wash Chains

Spot-free rinse is a customer-facing quality feature. When the RO stage fails you get spotting, complaints, and rewashes across every bay — a cost-effective element brings it back fast.

Common applications

  • Spot-free rinse RO
  • Reclaim water polishing
  • Multi-site standardization
  • High-throughput tunnels
Recommended: NanoH2O BW 400 ES — cost-effective

Pharmaceutical & Biotech

USP Purified Water and WFI systems depend on reliable RO pretreatment. Validation-conscious facilities need consistent, spec-verified elements — not whatever a distributor has in a container three months out.

Common applications

  • USP Purified Water pretreatment
  • WFI system pretreatment
  • Laboratory-grade water
  • Spec-verified documentation
Recommended: NanoH2O BW 400 R G2 — high rejection

Coastal Hotels & Resorts

Properties beyond municipal reach run onsite seawater desalination for potable, cooling, and F&B water. Seawater elements carry the high salt and boron rejection needed for compliant drinking water.

Common applications

  • Onsite seawater desalination
  • Cooling tower makeup water
  • F&B & potable supply
  • Island & remote operations
Recommended: NanoH2O SW 400 R — seawater

Municipal & Community Water

Small utilities use RO to hit compliance on arsenic, nitrate, and TDS. High-rejection brackish elements deliver drinking-water quality without oversizing the system.

Common applications

  • Arsenic & nitrate compliance
  • Brackish groundwater treatment
  • TDS reduction
  • Wellhead treatment
Recommended: NanoH2O BW 400 R G2 — high rejection
