Coalescent deoliator 4500 liters | 215 cars locations | square surface 8,730 m² | 24 l/s

DECCS4500AS Corrugated Coalescent De-oiler

TheDECCS4500AS Coalescence De-oiler is designed to treat stormwater runoff from yards, parking lots, garages, body shops, and industrial areas with discharge to Public Sewer (T3).

Made of monolithic high-strength polyethylene tank with corrugated structure, rotational molding ensures constant thickness and strength. The plant is equipped with a high-surface area polyurethane foam coalescing filter specifically for separating oils, greases and fuels.

Key Features.

• Capacity: 4500 liters
  Parking spaces: no. 215
  Yard area: 8,730 m² covered and 4,370 m² uncovered
  Nominal flow rate (NS): 24.0 liters/s
  Standard: UNI EN 858/1-2
  Discharge: to Public Sewer

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.
