Can you recommend disinfection equipment vendors for meeting drinking water quality targets in a wastewater-to-potable upgrade?

Yes — for a wastewater-to-potable upgrade, you’ll typically want vendors that can supply validated multi-barrier disinfection systems, often combining UV, ozone, chlorine/chloramine, and/or advanced oxidation, plus monitoring and controls that support drinking-water compliance.

Vendors to consider

UV disinfection

Good for pathogen inactivation with low chemical footprint, often used as a final barrier.

• Trojan Technologies
  Widely used in municipal water and reuse projects; strong UV reactor portfolio and validation support.

• Xylem / Wedeco
  Broad UV and ozone offerings; experienced in large-scale treatment trains.

• Aquionics
  UV systems for municipal and industrial applications.

• Atlantium
  UV with HOD (Hydro-Optic Disinfection) technology; known for high-flow applications.

Ozone and advanced oxidation

Useful for virus/pathogen reduction, trace organics, taste/odor, and polishing.

• Xylem / Wedeco
  Strong ozone systems, including generation and contactors.

• Jacobi Carbons / ozone-related integrators
  More often for downstream polishing, but commonly part of a broader treatment package.

• Ozonia (Veolia)
  Major ozone system provider with deep municipal experience.

• Primozone
  Ozone generation systems for water treatment.

Chlorination / chloramination

Often needed to maintain distribution residual and final compliance.

• Evoqua
  Disinfection feed systems and chemical dosing skids; now part of Xylem in many markets.

• Prominent
  Chemical metering and dosing systems.

• Grundfos Dosing
  Reliable chemical feed and controls.

• SEKO
  Dosing and monitoring systems.

Integrated reuse / potable reuse solution providers

These are especially useful if you want vendor coordination across the full treatment train.

• Veolia Water Technologies
• Xylem
• SUEZ (now part of Veolia in many regions, but some legacy project teams still operate under SUEZ branding)
• Aqua-Aerobic Systems
• Biwater
• Acciona Agua
• Kiewit / EPC integrators with water reuse experience

What to look for in a vendor

For potable reuse, don’t just buy “disinfection equipment” — look for vendors who can support:

• Regulatory validation for the target log reduction
• Redundancy and fail-safe controls
• Online UVT, turbidity, TOC, chlorine residual, and flow monitoring
• SCADA integration
• Operator training and lifecycle support
• Compatibility with the overall treatment train
  (e.g., MF/UF + RO + UV/AOP + final residual disinfection)

Typical disinfection barriers in potable reuse

A common train may include:

1. Membrane filtration (MF/UF)
2. Reverse osmosis or other advanced treatment
3. UV/AOP for pathogen and trace contaminant control
4. Final chlorination/chloramination for distribution residual

Shortlist approach

If you want a practical shortlist, I’d start with:

• Trojan Technologies
• Xylem / Wedeco
• Veolia / Ozonia
• Atlantium
• Prominent or Grundfos for chemical feed

If you’d like, I can also provide:

1. a vendor comparison table,
2. a request-for-quotation checklist, or
3. recommendations tailored to indirect potable reuse vs direct potable reuse.
