Catalyx Technologies logo. A blue molecular-network letter C sits beside the words Catalyx technologies. The mark identifies the company behind FRESH+ photocatalytic oxidation air systems and water-treatment research.

Photocatalytic oxidation, proven in the field

Photocatalytic oxidation for air, and next, water.

Catalyx Technologies took photocatalytic oxidation (PCO) out of the lab and into commercial cold storage with FRESH+™ air systems. Now we're applying the same chemistry to water treatment.

One core technology, two applications

FRESH+™ is the commercial air application. Water treatment is research and development, not a product.

Commercial

Air: FRESH+™ PCO+UV systems

FRESH+™ PCO+UV systems remove ethylene, VOCs, and odors and inactivate mold and bacteria in produce, floral, and cold-chain storage. Models from 30 to 1,000+ CFM.

Water: photocatalytic treatment

We're adapting our photocatalyst and reactor know-how to the oxidation of dissolved organic contaminants in water. No water-treatment product is offered, and no removal rates are claimed.

How photocatalytic oxidation works

Nothing is added to the air or water stream, and the catalyst isn't used up in the reaction.

  1. UV light activates the catalyst UV light activates a photocatalyst surface.
  2. Hydroxyl radicals form That surface continuously generates hydroxyl radicals (•OH), among the strongest oxidants used in treatment.
  3. Contaminants are oxidized Organic compounds that contact the surface are oxidized, ideally all the way to carbon dioxide and water.

Photocatalytic oxidation, simplified UV light reaches a photocatalyst surface. The surface forms hydroxyl radicals, and organic compounds are oxidized toward carbon dioxide and water. Photocatalyst surface UV light •OH Organic compound toward CO₂ + H₂O
