Oferta Tecnológica
11 DE 1169 3MWA
Una empresa alemana ofrece una solución de tratamiento biológico de agua para equipos de lavado de automóviles que permite obtener agua procesada limpia e inodora independientemente de si el agua se emplea en un túnel de lavado, autoservicio o túnel de lavado de camiones. La empresa ofrece sistemas biológicos de tratamiento de aguas residuales y componentes para soluciones de tratamiento a medida. Se buscan socios interesados en establecer acuerdos comerciales con asistencia técnica.


Biological water treatment for car washes
A German company offers a solution for the biological water treatment of car-wash systems providing clearly visible and odourless processed water, no matter if the water is used in a tunnel wash, self-service or truck wash. The company offers biological water treatment systems as well as all parts for turnkey waste-water solutions. They are looking for partners interested in a commercial agreement with technical assistance.
The German company is specialized in the treatment of waste water, e. g. containing petroleum products from car washes. It offers solutions for all occasions, when clear and odourless processed water is needed. The water treatment system that is used especially for car wash systems is based on the water consumption. Clear water can be guaranteed by means of bioreactor processes, while saving fresh water.

All accumulating water of a car wash is collected and passes a combined oil and coalescence separator. From there it passes a sludge trap, where a sedimentation takes place.

The water that has undergone this filtration process then flows into a first basin where with the help of a biological system specially adapted microorganisms start to clean up the waste water. Depending on the required water quantity the water then flows downstream into the second and / or third biological basin, etc. After having passed the biological treatment the processed water is clear and odourless. This water quality is reached without using any chemical supplements.

The cleaned water flows into a clarifier. In the connected downstream equipment the water is then directly delivered to the different consumers by pumps. In this way maximum savings of freshwaters can be achieved. Only the evaporative and carryover water has to be supplemented. This supplement can be rainwater.
The biological water treatment system is normally underground. An above-ground solution is also practicable.

This water quality can also be used for high pressure. But in order to comply with the mandatory standards - and it is guaranteed that high pressure processings can be operated with process water without problems - such processing should be followed by the adsorption column chromatography (ASC) process.
Here the water is adsorbed and filtrated in a single step. Solids are filtrated up to 20 µu. By the use of a downstream UV system the obtained water is conform with the EU standard for bathing water.

Current and Potential Domain of Application: All applications which require the biological treatment of waste water and the re-use of the processed water, e. g. car wash facilities.
