CET systems for toilet waste water suction

Aquafrisch has developed a system for extracting and loading sanitary water for trains that allows a simple, fast and safe emptying and filling process.

The system of extraction and loading of Wc’s developed by Aquafrisch allows the emptying of the tanks of the trains. The system consists of independent extraction stations distributed along the train track.

Each station has its own hoses for extraction, rising and filling the tanks. The extraction is carried out by means of a compressor / depressor and all the sewage is stored in an accumulator tank.

In addition, equipment for cleaning and loading biocides can be designed. The equipment is controlled through touch screens allowing a simple and intuitive operation.

Fixed cet system for toilet waste water suction

The system consists of independent extraction stations distributed along the railway track. Each station has its own extraction hose and may also include other hoses for the rinsing and filling of the train tanks. The extraction is carried out by means of a pneumatic group that generates a vacuum to extract the fluids from the train.

Thus, by means of this vacuum, contact between the pneumatic group and the extracted fluids is avoided. In this system it is enough that the pneumatic group inverts its pressure to empty the storage tank, to which the water extracted from the WCs is taken. In addition, a biocide dosing system can be included. The vacuum is generated centrally in the storage tanks, so that the plant operators only have to connect the hoses and operate the valves at each station.

The control can also be automatic. In this case, the plant operator connects all the hoses, and the system executes the emptying sequence of all the stations. The automatic plants have touch screens for simple and intuitive operation.Our designs conceive from 1 to more than 50 extraction stations.

Mobile cet system for toilet waste water suction

For greater flexibility, we supply mobile extraction systems, installed on trailers or electric vehicles. Aquafrisch combines steel or GRP tanks with a capacity of up to 2000 litres with vacuum pumps, which allow a great adaptation to the needs of each client. The extraction is carried out by means of a pneumatic group that generates a vacuum to extract the fluids from the train. This vacuum avoids contact between the pneumatic unit and the extracted fluids. In this system it is enough that the pneumatic group inverts its pressure to empty the storage tank. The rinsing and subsequent refilling of the train cisterns can be included.
