PlanetTEK — modular biological wastewater treatment systems
PlanetDISK® rotating biodiscs — a flexible solution from 50 to 700 m³ per day. Assembled for the specific task, scaled up in phases, and installed even as an upgrade to old treatment plants. 80% less energy, no odour, noise below 50 dB.
Not just discs — a system assembled for your task
At the heart of PlanetDISK® is a rotating biological contactor (RBC): a biofilm of natural microorganisms lives on the rotating discs and breaks down pollutants without air injection. This is the biological core around which ZIKO builds the remaining units for the specific site — from screens at the inlet to tertiary polishing at the outlet. That is why one technology covers tasks from a hotel to an entire settlement.
A core plus modules for your wastewater
At the heart are the PlanetDISK® biodiscs. If needed, pre-treatment is added at the inlet and polishing at the outlet: the plant is assembled for your actual wastewater composition and discharge requirements.
Before the discs · pre-treatment

PlanetDISK® biodiscs
The core stage — biological wastewater treatment on rotating discs.
After the discs · polishing
Depends on the discharge requirements.
The configuration is determined at the calculation stage — you pay only for the units your site actually needs.
Modularity that monoblocks don’t have
Upgrade of old treatment plants
PlanetTEK is built into existing facilities as a biological stage — no need to build everything from scratch. Real savings for municipalities and industry with outdated plants.
Scale up to 700 m³
One technology size range — from a small hotel to an entire village; capacity is added in phases.
Adapts to the wastewater
The unit configuration is matched to the actual composition and volume of wastewater — more flexible than a fixed body.
Treatment in three stages
Mechanical treatment
The wastewater is freed of large solids and fats, and the uneven flow is evened out — so the next, biological stage works stably.
Biological treatment
The core stage: on the rotating biodiscs, natural microorganisms break down organic pollutants — without air injection, quietly and energy-efficiently.
Polishing and disinfection
The clarified water is brought to compliant quality and disinfected — suitable for discharge to the environment or reuse.
What tasks PlanetTEK covers
| Client | Volume | PlanetTEK’s role |
|---|---|---|
| Larger-format HoReCa | 50–150 m³/day | modular plant + grease trap, screens |
| Cottage estates / recreation bases | 150–300 m³/day | one plant for the whole estate, phased scaling |
| Industrial polishing | up to 700 m³/day | biological polishing after the physico-chemical stage |
| Municipalities | up to 700 m³/day | a settlement without central sewerage |

When modular PlanetTEK and when monoblock BioDisc®
| Criterion | BioDisc® (monoblock) | PlanetTEK (modular) |
|---|---|---|
| Format | entire system in a single body | core + add-ons for the task |
| Capacity | up to 60 m³/day (in parallel — up to ~180) | 50–700 m³/day |
| When to choose | small site, need it fast and turnkey | large volumes, non-standard wastewater, upgrade of existing plants |
| Installation | on a prepared base, minimal works | flexible, including retrofit into existing facilities |

(Greece) · Xelera (Mexico) · ThyssenKrupp · Unilever · Rotary International · Capital Water (Chile) · KfW (Germany) · Azersu (Azerbaijan).
Frequently asked questions
How does PlanetTEK differ from a monoblock?
PlanetDISK® is a biodisc core to which the required units are added (screens, grease trap, settler, etc.). Hence the flexibility in volume (up to 700 m³) and the ability to build the system into existing plants.
Can old treatment plants be modernised?
Yes, this is one of the main scenarios: PlanetTEK is added as a biological stage to an existing facility, without building from scratch.
How much energy does it consume?
About 80% less than classic aeration plants — thanks to rotor technology without powerful blowers.
Will there be odour and noise?
Noise below 50 dB, no odour — an aerobic process without discharge of contaminated air.
What is the maximum volume?
Up to 700 m³/day in our positioning; the technology scales to 3,500 PE.
Is it suitable for polishing after physico-chemical treatment?
Yes — biological polishing by PlanetTEK after the physico-chemical stage allows discharging water to the environment or returning it to the process cycle.
