Overview
System O)) — what is it?
At the center of System O)) solutions lies Advanced Enviro))Septic technology. Aerobic and anaerobic microorganisms that develop around perforated pipes help break down the organic pollutants in domestic wastewater biologically.
The system handles the distribution of wastewater, its biological treatment and, depending on the project, its release into the soil or its routing to advanced treatment for reuse, all within an integrated process. Thanks to the passive operating principle, the need for electric motors, continuous chemical dosing and complex mechanical equipment is minimized.
DBO International states that the System O)) solution family has reached more than 250,000 installations worldwide and is used in different geographical and climatic conditions.

Operating Principle
System O)) — how does it work?
In System O)) installations, wastewater passes through pre-treatment and is then directed to the distribution and treatment lines. Treatment is carried out by the biological layer that develops around the pipes, without any externally supplied energy.
Water is directed to the System O)) distribution and treatment lines
Water leaving pre-treatment is distributed into perforated pipe lines running across the treatment area.
Microorganisms break down organic pollutants
The aerobic and anaerobic microorganisms that develop around the pipes help break down the organic pollutants in the wastewater biologically.
Treatment, filtration and infiltration processes are completed
Filtration and soil infiltration stages are planned according to the project design and ground conditions.
With suitable advanced treatment the water can be put back to use
When the necessary advanced treatment or disinfection is applied, the water can be used in the areas permitted by regulation.
Attributes
The features that set the system apart.
The attributes below stand out because of their direct effect on the system's operating load, energy needs and environmental impact.
Passive and biological operating principle
Treatment is carried out by the biological layer that develops around the pipes; the process relies on natural mechanisms.
Treatment process requiring no electricity
The treatment process is designed to work without an electrical connection.
A structure with no motor or complex mechanical equipment
With no moving components, the number of parts that can fail and the need for servicing are reduced.
Quiet operation
As there is no need for aeration or mechanical equipment, quiet operation is targeted under correct design conditions.
A process that needs no continuous chemical use
Treatment is designed to be carried out biologically without routine chemical dosing.
Permanent biological filter medium
The filter medium is designed to be permanent; it is not a consumable that must be replaced regularly.
Adaptability to different terrain and climate conditions
According to the manufacturer's declaration, the system has been applied in different geographical and climatic conditions.
Scalability for residential, communal and corporate projects
The solution family can be designed at different capacities according to the project's user numbers and flow.
Enabling reuse with suitable advanced treatment options
When the necessary advanced treatment and disinfection are provided, treated water can be evaluated in the areas permitted by regulation.

Reuse
Treated water is not a load to be disposed of.
When a suitable treatment level is achieved and the relevant regulations and quality criteria are met, the effluent can be used in the areas below. The use scenario is determined separately for each project.
01
Agricultural irrigation
02
Landscape irrigation
03
Toilet cistern supply
04
Other technical uses deemed suitable
The reuse goal requires the system to be addressed as early as the design stage. If we discuss from the start where the water will be used, we also size the required treatment stage correctly.

The technology has been certified against NSF/ANSI 40 Class I, BNQ 3680-600 and BNQ 3680-910 and carries the CE marking. In October 2020 it was assessed with the Solar Impulse Efficient Solution label.
Quiet, low-odour operation is targeted under correct design and usage conditions. The absence of aeration and mechanical equipment supports this objective.
The size of the treatment area varies with the project's capacity, ground permeability and the chosen discharge method. It is assessed together with site and flow data.
When suitable advanced treatment and disinfection are provided, it can be evaluated for irrigation and similar areas. The use scenario depends on local regulations, project design and disinfection conditions.
Applicability in existing buildings is assessed after the usable area, existing infrastructure, ground conditions and flow have been examined.
