Compliance and Standards.
The coalescing de-oiler fully complies with the following standards and requirements:
- UNI EN 858/1-2
- Legislative Decree no. 152 of 03/04/2006 part III
- C.A.M. 2.2.8.2 - Collection, purification and reuse of rainwater
Operation
The system reduces the velocity of the influent and incorporates a stilling zone that facilitates the separation of lighter particles. The coalescing filter action optimizes de-oiling in compact spaces, improving performance over conventional separators.
Advantages
- Simplified underground installation
- High efficiency due to coalescing filter
- Lightweight and corrosion-resistant design
- Low programmable maintenance
Maintenance
To ensure consistent performance, periodic inspections of the coalescing filter and separation zone are recommended as provided in the technical manual.
