Use and specifications
1. SEPARATION AREA: stilling zone in which floating substances such as oil, grease and any foam are separated from the effluent and accumulate on the surface, while the heavy substances (stones, grit, pieces of rubber and metal,…) settle on the bottom of the tank.
2. ACCUMULATION AREA: oils separated from the effluent accumulate on the surface.
3. HEAVY SEDIMENT ACCUMULATION AREA: the heavy materials separated from the effluent accumulate on the bottom of the tank.
4. COALESCING FILTER: fine micro-bubble polyurethane filter inserted into a stainless steel grid, which can be extracted thanks to the presence of a base and guides, also made of stainless steel. The coalescing filter is able to join the fine particles of oil present in the effluent to form larger drops big enough to migrate towards the surface, thus separating from the effluent.
TECHNICAL CHARACTERISTICS
Oil separators with coalescing filters allow improved performance to be obtained in removing light substances. The system makes use of a polyurethane sponge support on which the oil and hydrocarbon particles collect until their dimensions are such that enable them to settle away from the effluent by gravity. This treatment is recommended in the presence of particularly severe limitations on the discharged concentrations of mineral oils and hydrocarbons. It is advisable to install a grit separator upstream of the oil separator in order to prevent solid particles from clogging the filter meshes.
USE: treatment of surface drainage water from covered and open-air hardstandings, car parks, car showrooms, garages,…
REFERENCE REGULATIONS: Leg. Dec. 152/2006, standard UNI EN 858-1 . Separation systems for light liquids (for example diesel and petrol). Part 1 – Principles of design, performance and product testing, marking and quality control.
INSTALLATION DIAGRAM
AUTOMATIC FLOAT VALVE (ON REQUEST)
Smooth
TECHNICAL CHARACTERISTICS: float valve in plastic calibrated for light liquids of density > 0.85 g/cm3.
USE: when installed inside coalescence type oil separators it allows the outlet pipe to be closed automatically when the maximum oil containment level is reached.
