Reprotex has developed the world’s first mobile water recycling plant for industrial waste water. The system purifies contaminated process water directly on site for reuse or for safe discharge into the sewer system. An ecological and economical stroke of genius!

Who is ReProTex?

ReProTex is a company from Upper Austria that manufactures a patented mobile plant for the treatment of industrial wastewater and sells or rents it worldwide.
After more than 5 years of intensive development work, ReProTex presented at the end of 2015 the world’s (!) first plant ready for series production, which treats wastewater in real time for reuse. The system is mounted in a container and is able to purify process wastewater of up to 200 l/min and return it as clear water for immediate reuse or discharge into the sewage system or flowing waters.
This unique system is suitable for a wide range of industrial applications, such as high-pressure cleaning of road surfaces, tunnels and bridges, paint stripping of ships and large tanks.
The system is built, mounted and configured in Upper Austria but can be serviced, monitored and maintened remotly.

What makes the ReProTex system so special?

Until now, industrial wastewater has either been discharged somewhere (legally or illegally) or had to be dumped at high costs. The strict environmental regulations in Europe, but also worldwide, are now causing the costs for disposal to rise sustainably.
In this environment, the ReProTex system is unbeatably attractive because

  • fewer resources (valuable drinking water) are required: 95% reduction,
  • only a fraction needs to be landfilled (excluding the separated solids),
  • less personnel is required, and
  • thereby considerable cost reduction is realized.

The advantages speak for themselves, because on the one hand the environment is sustainably protected, as less precious water is needed, and at the same time the disposal costs for the customer are reduced by up to 70%!

How does it work?

The system is most effective when large, highly polluted or toxic wastewater volumes are produced, such as when working with high-pressure water. Examples are removal of floor markings, tunnel cleaning, facade cleaning and bridge renovation, … or when something is cut, e.g. concrete.

The mobile water treatment is based on a chemical-physical procedure that filters the particles introduced by the working process out of the wastewater again. Flocculants (0,2 l per 1.000 l of water) are added to the wastewater, which leads to precipitation with subsequent flocculation. These phases are separated by sedimentation. The sludge is pumped to the outside via a sludge trap. The water has hydrant quality after treatment by ReProTex. This means that it does not contain any suspended particles larger than 1 µm (= 0.001 mm). A decisive criterion of the system is that the system is also suitable for modern high-pressure pumps that operate at up to 5.000 (!) bar.

An industry in transition

Up to now, industrial wastewater has simply been disposed of more or less illegally or dumped in landfills at high cost. Increased environmental standards in the EU, but also in many other countries of the world, are causing the costs of disposal to rise significantly in the form of draconian penalties or higher landfill fees.

In the absence of alternatives, not much has changed here in recent years. However, the savings factor of this mobile wastewater treatment can be made tangible using the example of a tunnel cleaning system:
1 system saves around 4,8 million litres of water per year (equivalent to 400 tankers!) This reduces the cost of water procurement, disposal, landfill and personnel by up to 70%.

A great way to protect the environment and save money at the same time. Not without reason, ReProTex has won numerous awards, including

  • Winner of the ÖGUT Environmental Award 2018 – World without waste
  • Top 5 at the GreenTec Awards 2015, Europe’s largest environmental and economic prize
  • Winners of the Energy Globe Upper Austrian Water Award 2017 and 2015
  • Excellent Project in the context of the Daphne 2014 Environmental Technology Award

What does ReProTex need capital for?

The interest in ReProTex wastewater recycling is enormous. While the sale of plants is continuously growing, ReProTex wants to meet the requests of new customers with the rental plants to be financed. Since there is no comparable system available, the majority of clients are interested in renting a plant as a first step. In most cases a follow-up purchase is then made.
Through this measure, the company plans to secure the most attractive share of this market for wastewater recycling. Once these rental plants will have been built, sufficient cash flow will be available to finance further growth through the rental or sale

Financial outlook
