Wastewater purification works without chemicals and external energy input. Environmentally, it is very important, that the whole process based on the natural model, and it can be made with a very small energy input. The emmission, compared to the traditional canalization and wastewater purification systems, is almost negligable. The modular structure lets us take advantage of the optimal effectivity of capacity, depending on the number of housing units. Another important fact: our system has the positive effect of reducing the residual hormons and medicines, which can not be made with traditional purification systems.

During the purification, the system is closed-acting. The outcoming water, according to the European quality regulations, can get into open rivers and underground water, if it is useful for dessication of soil. It can be used for irrigation, fishponds, watering of animals, etc. The purified wastewater contains useful trace elements, so within the confines of law, it can be used as water supply of agricultural lands. With these actions, we can contribute in saving precious drinking water.

Keeping waters at their site serve the quantitative defence of underground-waters. As the 96% of the inland water supply comes out from underground waters, it would be important if the exploited waters would stay within the borders of the country, and wouldn't be deflected with surface waters across them.

The quality of biologically purified wastewater reaches better values and quality efficiency, than the ones, handled with traditional purification systems of big charge, and huge energy needs.

It's proven, that these values are all the year round far below the maximum limits. (The root-zone based purification systems reach the stricter parameters, prescribed to 80-100 thousand housing units.)

The handling of the remaining wastes after purification is also an important case. In our systems, the treatment for this is making humus from them in separated basins, using sedge (Phragmites australis). As an alternate possibility, sewage sledge can be used instead of chemical manures, in adequate amounts, according to the regulations.

The life expectancy of the system is about 25-30 years, which can be longered for a same-lenght period with just a small intervention (just with resetting the substrates).

SUMMARY: Economical and environmental advantages of the biological wastewater purification system:

  • From the enironmental point of view, it's absolutely unique
  • Building costs are far more cheaper than any other systems' (with about 40-60%, compared to the artificial wastewater systems)
  • Maintenance and upkeep costs are also low, because machines with high energy needs aren't needed to be installed, and the self-ruling biological degradation makes the usage of external energy sources unneccessary (costs about 10-20% percents of the traditional purification systems')
  • No external energy or chemicals are needed in the operation
  • Accomodates with the landscape, aestetic, creates further life-spaces for wildlife
  • In Western-European states, where drainage is unprofitable, this system has been used successfully for years, because it's energy-saving and environmentally friendly
  • Despite the planning and the construction procedure needs a huge specialized knowledge, the actuation is easy

  • It's efficiency has been proven for years, by many references
  • The capacity of the plant can be flexibilly expanded or shortened
  • Life expectancy of the system is very long, and it has a great rejuvenation abilty
  • The secure isolation of the sedge-beds and other technological elements, prevents the pollution of the soil and the underground water
  • Odors are negligible, because the wastewater reaches the root-zone of the sedge in a closed pipe, and the degradation process takes place below the surface too
  • The system can effectively operate at winter too
  • Ecologically useful, aestethic solution
  • Just a small amount of waste (e.g.: sewage sludge) with a requiary of further treatment remains

Biological wastewater purification in practice

The root-zone based wastewater purification system we present, is a popular solution worldwide. This environmentally friendly system has been used successfully in Western-Europe for decades. It has an unvaluable importance in the consciousness of sustainable development. Based on the experience of our many years long made survey, the usage of these systems in Eastern-Europe is neglected. It's mainly caused by the inadequate planning, and the lack of professional experience.

It's a modern alternate of public works, and gives an economical and environmentally friendly solution for settlements under 5000 housing units, and for scattered settlements too. Comparing this system with traditional wastewater purification systems, we can say, that the smaller the population, the more eficcient the root-zone based purification system constructed, instead of the traditional ones. The biggest long-term advantage is that because of the lack of external energy, lowers the maintenance cost with about 10-20% compared to other systems. This causes, that more money can stay at the households, and it helps the sustainability. The root-zone based purification system gives a reachable solution for disadvantaged settlements too.

It can also be used for post-purifying of industrial and agricultural wastewaters with inadequate parameters.

We undertake a 10 years long guarantee for the purification systems. and we also insure a 2 years long free repair service.
