O3TECH Ozone Technology for Yacht Wastewater Tank Vent Odor Control

[/et_pb_text][et_pb_text _builder_version=”4.27.2″ _module_preset=”default” ul_font_size=”20px” global_colors_info=”{}”]

NO MORE BAD SMELL FROM BLACK/GREY WATER TANK

[/et_pb_text][et_pb_text _builder_version=”4.27.2″ _module_preset=”default” header_font_size=”3px” header_2_font_size=”20px” text_orientation=”justified” global_colors_info=”{}”]

Unpleasant odors from black and grey water tank vents significantly impact yacht comfort and onboard experience. O3TECH’s advanced ozone treatment system provides an innovative solution that completely neutralizes offensive odors before they escape by the vent outlet.

How It Works

Ozone (O3), nature’s most powerful oxidizer, breaks down odor-causing compounds at the molecular level. When introduced into tank ventilation systems, ozone molecules react with hydrogen sulfide, ammonia, and other malodorous gases from waste decomposition, transforming them into odorless substances like water vapor and carbon dioxide.

Innovative Decanter System

O3TECH utilizes an inline decanter positioned in the vent pipe, creating a compact reaction chamber where high ozone concentration is maintained. This design innovation is crucial: instead of requiring a large ozone generator to treat the entire tank volume, the system focuses treatment in a small, precisely dimensioned volume based on tank size. This approach dramatically reduces equipment size while maximizing efficiency—the ozone generator remains compact while delivering superior odor elimination.

Key Benefits

  • Compact system through decanter technology
  • Automatic operation without chemical additives
  • Minimal energy consumption
  • Eliminates storage of hazardous deodorizing agents
  • Provides sanitizing effect, reducing bacterial growth

Environmental Advantage

Unlike chemical neutralizers, ozone naturally reverts to oxygen after oxidation, leaving no harmful residues or environmental footprint—ideal for yachts in protected marine zones.

O3TECH’s decanter-based ozone technology transforms wastewater odor management into a space-efficient, fully controlled aspect of yacht operations, ensuring the highest standards of comfort and environmental responsibility.

O3tech Ozone Odor Control Systems – Italian Leader

KTO Supply is exclusive marine distributor for O3tech, the Italian leader in ozone-based odor elimination systems for grey and black water tank vents. Advanced technology to completely eliminate bad odors from wastewater systems on ships and yachts.

The Problem We Solve

Grey and black water tanks on vessels produce intense malodors that escape through vent pipes, creating uncomfortable conditions on deck and in accommodation areas. Traditional solutions like filters or chemicals provide only temporary relief.

O3tech Ozone Solution

  • Complete elimination of odors at the source
  • Treats air in vent pipes before discharge
  • No chemicals or consumables required
  • Compact units for easy installation
  • Silent operation

How It Works

O3tech systems inject ozone directly into the vent line of wastewater tanks. The ozone oxidizes odor-causing compounds (hydrogen sulfide, ammonia, mercaptans) converting them into odorless substances. Clean, fresh air is discharged from vents.

Applications

  • Luxury yachts and superyachts
  • Cruise ships and passenger vessels
  • Commercial vessels with large crews
  • Offshore platforms and rigs
  • Marina pump-out stations
  • Shipyard waste treatment facilities

System Features

  • Automatic operation with no crew intervention
  • Low power consumption (50-200W)

Why O3tech is the Italian Market Leader

  • Over 500 installations on vessels
  • Proven technology with 10+ years marine experience
  • Designed and manufactured in Italy
  • Immediate technical support in Italian ports
  • Custom solutions for specific vessel requirements
  • Best price-performance ratio in the market

Say goodbye to embarrassing odors on board. O3tech systems guarantee a fresh environment for crew and guests.
