Waterbody Remediation and Pond Desludging - Through an Aerobic Environment

"Thanks to the oxygen supplied, the water and sediments are kept aerobic and phosphate fixation in the sediments is so strong that algae growth is largely suppressed."
- Dr. Ernst Ecker, publicly appointed and accredited expert for water and wastewater analysis (IHK Rheinl.-Pfalz)
Final Report Tank Ditch Malsch, 2012

Addressing Oxygen Deficiency in Stagnant Waterbodies

"Drausy manufactures water aeration hoses that allow the diffusion of particularly fine air bubbles. This results in a particularly high oxygen utilisation."

Comparison Between Point and Linear Aeration of Wastewater

"The aeration significantly reduced the formation of sulphide. The linear aeration was even able to oxidise the sulphide introduced into the plant, so that the sulphide concentration was reduced. Odour emissions were thus avoided."

Operation principle and material qualities

"As a result, all outlet openings have the same outlet quantities. This feature allows liquids and gases to be introduced into the wastewater over long distances (up to 10 km) in a fine and uniform dosage."

1st prize for the golden IKT manhole cover

"The central elements were targeted aeration guidance in the opposite direction of flow through the use of in-house developed aeration closures and chimneys, as well as the use of in-line aeration with an air metering pipe in the last part of the pressure line."

Excerpt from DWA-M 154-2 data sheet

"Immediately after the installation, only a few H2S peaks were measured at the degassing well...From the operator's point of view, a site-specific and cost-effective solution was found. The installation has been in place for 17 years and continues to operate."

How it works:

Oxygen is the key to natural self-purification. The Drausy® system introduces ambient air in fine bubbles exactly where it’s needed – for example at the bottom of a pond or inside a pressurised sewer line. This enables biological sludge degradation, odour reduction, and phosphate removal.

SOLUTION FOR YOUR WATERInformation on sludge decomposition, sediment, pond quality

Healthy Pond

Our range of services:

For decades, Drausy GmbH has been synonymous with healthy, oxygen-rich water - thanks to the so-called aerobic media: a unique method of oxygenating the water body and the water bottom with tiny air bubbles - effectively, with maximum efficiency and without additives. Patented in 1998 and produced in a German-French cooperation.

Reduce mud

Oxygen enrichment of the soil environment leads to volume reduction (organic matter), dissolution of decomposition gases and control of siltation.

stop oxygen deficiency

The entire water is enriched with oxygen - creating a balanced and healthy habitat for aquatic plants and animals. Fish kills are a thing of the past.

Preventing algae blooms

Our technology removes excess substances from the water in a sustainable manner. The formation and growth of algae and cyanobacteria is thus greatly reduced.

Stop generating greenhouse gases

The targeted oxygen enrichment prevents the formation of undesirable organic structures - thanks to a fine bubble mat at the bottom. This prevents the formation of decomposition gases.

Preventing odours and corrosion

Unpleasant odours are eliminated by continuous fine-bubble aeration. Corrosive sulphurous gases or gases hazardous to health can no longer form in the aerobically maintained wastewater discharge pipe.

Improve leachate

On-site treatment and subsequent infiltration are achieved when organisms are adapted and enough oxygen is available.

Greywater treatment plant with aerated plants

Drausy® is part of vertECO: this technology treats greywater using a vertical, plant-based ecosystem.

In situ soil remediation

Laying the Drausy® system directly on the surface of the remediation horizon can reduce CHC soil contamination.

sustainable solutions: Our product criteria

Artificially created habitats do not regenerate themselves. This is where we come in - in an efficient, environmentally friendly and sustainable way.

Quality

Highest quality standards, best material.

We configure your system individually in our own factory. Quality control is carried out by us. We always produce using state-of-the-art technology. The basic material used is the highest quality TPU on the market. Only where Drausy® is on it is Drausy® in it.
