ENVOCHEM®

HIGH SPEED TRAIN CLEANING PLANT

In the year 2000 a new high speed train cleaning plant was constructed at Frankfurt. EnviroChemie’s Envochem® waste water treatment plant is to be found in the adjoining building next to the extensive cleaning plant. The water used for washing is treated in three separate water circuits. In all three circuits the waste water is mechanically  freed and cleansed of  impurities by means of self-cleaning reverse filters, so that it is finally ready for re-use within the plant. Since the most impure waste water results from the first cleaning phase, this circuit is linked to a generator where the water is cleaned chemically and physically. The resulting recycled water can either be separated and re- used in the various circuits or released into the canalisation. All standards laid down by the authorities are more than adhered to.

AIRPORT MUNICH

ENVOPUR® UFI

RECYCLING OF AIRCRAFT DE-ICING

At the de-icing stations aircrafts are sprayed with de-icing agent immediately before the take-off. Not only for ecological but for economical reasons as well, at the airport Munich the surplus agent is caught, purified and fed back into the system for re-use. High demands are made on the recycling process.

The recycling of the de-icing fluid is carried out at the airport Munich since 1992. With that process one receives the primary substance of the de-icing agent after separation of the undissolved components, removal of dissolved substances by ion-exchange and a final thermal concentration.

Nowadays, the de-icing agents to be recycled contain thickening additives, which block the main treatment step in the above described recycling process. For this reason the recycling plant at the airport Munich was expanded by the ultrafiltration unit type Envopur® UFI to separate these thickeners completely. The cut off was chosen to separate blocking substances (thickeners) and to recover valuable chemicals (Glycol), which pass through the membranes.

HHLA Container Terminal Tollerort, Hamburg

Split-O-Mat® wastewater treatment and recirculation plant for new van carrier wash station

The HHLA Container Terminal Tollerort (CTT) completed its new workshop at the end of 2009. The building, which measures 6500 square metres, is divided into the following areas: Van carrier (VC) workshop, VC washing bay, spreader workshop, warehousing area and offices. At the heart of all this is the VC workshop which, with its surface area of 1950 square metres and height of 24 m, can accommodate eight VCs at once.

As regards the new van carrier wash station, in 2009 the ARGE CTT workshop building awarded EnviroChemie the contract to supply, assemble and commission a modern Split-O-Mat^® SOM 2000 wastewater treatment and recirculation plant. The plant was commissioned in November 2009 and treats the washing water so that it can be reused in the same context. This constantly saves precious drinking water and cleaning agents and makes a significant contribution towards protecting the environment. The plant operates using a self-contained circuit, which means there is no connection to the sewer. Only losses due to carryover and evaporation need to be compensated with fresh water.
