Advantages of the integrated screenings washing IRGA
- less odour annoyance
- reduction of volume and weight due to the wash-out of up to 95% of the faeces, resulting in greatly reduced disposal costs
- increased dewatering efficiency, consequently also a higher thermal value in case the screenings are incinerated
- return of the faeces into the biological degradation stage of the purification process
- functional construction, as the screenings washing is integrated together with the screenings press in the ROTAMAT® plant.
- easy subsequent installation
The design of the ROTAMAT® plant enables modifications to be made later, i. e. the plant can be suited to requirements which may arise after some time. Thus the integrated screenings washing can be installed later.
- best quality for low price
- use of service water is possible, that means no use of fresh water
