Three strengths

What sets the STABI-KOM apart.

  • No electronics in the wastewater

    The SSB® process works with compressed air: inside the tank there are no pumps, no motors and no moving parts. The technology stays dry at the edge of the plant, where it is easy to reach.

  • Low maintenance and long-lasting

    Only aerobically stabilised sludge is produced, and its removal can be put off for years. This noticeably reduces running costs, with long-term reliability.

  • Biological, and strong even at low load

    It treats water without chemical additives and keeps performing even when the house stands empty for a season. The worry-free option for places used seasonally.

In practice

Installing a STABI-KOM.

Delivery, crane lift and installation of a STABI-KOM concrete tank on site. The plants shown are in the range of 4 to 12 PE, for single-family and multi-family homes. German AQUATO technology in real use.

How it works

The SSB® biological process

  1. 1 Biological aeration No electronics in the water
  2. 2 Settling The sludge settles
  3. 3 Discharge Clear water flows out
The STABI-KOM uses the SSB® process: aeration, settling and discharge of clear water, all driven by compressed air. There are no electronics in the wastewater, which makes it especially robust and low-maintenance.

What is included

The components of the STABI-KOM.

The technology arrives pre-assembled in the tank. It is placed, connected and the K-PILOT control unit is switched on: depending on size, the plant is installed in one to three days.

  • Air lift set

    The airlifts move the water between chambers using compressed air only, with no pumps in the wastewater.

  • Disc aerator

    Introduces the air as fine bubbles for the biological stage. Other aerator shapes are available depending on the tank.

  • Compressor

    Produces the compressed air for the whole process, sized according to the population equivalents.

  • K-PILOT control unit

    The plant's control unit, installed in a dry place outside the tank. You simply plug it in: it runs the cycles and reports faults. After a power cut it restarts on its own.

No electronics in the water. No chemicals in the cycle.

Robust technology that protects water and soil, year after year.

Technical data

STABI-KOM models at a glance.

The STABI-KOM covers the range from a single-family home to a small housing development. The final values depend on the project; we review them with you during the consultation. The energy figure refers to the CE-certified reference size; for larger sizes we state it per project. All models are housed in robust polyethylene tanks with a walk-on cover rated up to 200 kg; up to 8 PE one tank is enough (up to 6 PE about 4.9 m³, at 8 PE about 6.4 m³ of usable volume), and larger plants have several. As a complete plant, the STABI-KOM carries the CE mark to EN 12566-3.

Tanks

The tanks for the STABI-KOM.

Up to 6 PE, the walk-on KL-02 plastic tank is used (installation depth 1.75 to 2.05 m). From 8 PE the standard is the larger KL-06 with 6,500 litres (installation depth 2.52 to 2.72 m): one tank at 8 PE, two from 10 to 16 PE. Larger plants are sized per project, from 27 PE with the elongated high-volume KL-09 tank. Alternatively, AQUATO supplies the complete plant in a BM-03 concrete tank. If the tank is built in concrete on site, a local construction company builds it following AQUATO's drawings; the technology, the drawings and the coordination with that company go through us. Because it is built on site, this option needs a little more planning time. The delivered plastic tank comes with up to 25 years of manufacturer's warranty. The material warranty is based on our statistics and tests, see the Installation and Operating Manual.

Purchase options

Two ways to receive your plant.

The technology comes from Germany. For the tank there are two routes, which we recommend depending on location and budget.

  • Recommended

    Option A

    Complete plant from Germany, with plastic tank.

    The tanks with built-in SSB® technology arrive from AQUATO configured and factory-tested. The compressor and control unit sit dry outside the tank, so there are no electronics in the wastewater. On site, all that remains is excavation, placement and connection.

    Why we recommend it:

    In most projects, the delivered plastic tank works out cheaper than a concrete tank built on site, and it is installed much faster.

    The tank arrives watertight and factory-tested, with up to 25 years' manufacturer's warranty.

    What you receive:

    • Complete plant with plastic tank, assembled and tested
    • CE conformity according to EN 12566-3 for the delivered plant
    • Up to 25 years' manufacturer's warranty on the tank
    • On site: only excavation, placement and connection
  • Option B · Alternative

    Technology from Germany, concrete tank built on site.

    The SSB® technology, compressor and control unit come from the AQUATO factory. Your local partner builds the tank in concrete according to the AQUATO plan (dimensions, reinforcement, connections).

    When it makes sense:

    Only when the project requires it, for example for very large volumes or when concrete construction is taking place on site anyway. In most cases, the delivered plastic option is more economical.

    What you receive:

    • SSB® technology, compressor and control unit from AQUATO Germany, ready to operate
    • AQUATO plans for building the concrete tank
    • Support with the on-site acceptance inspection
    • CE conformity through the technical set; the warranty remains in place

The STABI-KOM has no technology inside the wastewater; only the tank is bulky. Here the delivered plastic tank (Option A) is the most economical option.

During the consultation we recommend the right option for you. In most South American projects, the delivered plastic plant (Option A) is the most economical.

Applications

Who the STABI-KOM is made for.

  • Country house between mountains and a green garden

    For homes

    If you value a particularly long-lasting, low-maintenance plant, the STABI-KOM is the high-quality alternative to the PUMP. No technology in the wastewater and minimal sludge removal.

  • Aerial view of a coastal village among palm trees and vegetation

    For hotels and tourism

    In lodges, cabins and small hotels with varying occupancy, the STABI-KOM keeps performing even when occupancy is low. For larger resorts we move up to the ORKA.

  • Modern house under construction

    For property developers

    One shared STABI-KOM for several houses: you pay for the technology, installation and maintenance once, not for each house. No electronics in the wastewater, for 4 to 50 people.

First step

Ask for a consultation on the STABI-KOM.

In the free consultation (30 to 45 minutes) we look at the location, the load and the ground, and recommend the right model size. We reply within two working days.
