rain water treatment system series IPP/B
EURO MEC’s rain water treatment system, series IPP/B, is used for medium sized surface areas and facilitates the partial treatment of rain water through the use of an initial catchment basin then sand, oil and hydrocarbon separation units with or without a coalescence filter.

These systems consist of circular prefabricated basins constructed with reinforced concrete circular rings in reinforced concrete with carriageable covering slabs and cast iron manhole covers class D400.

HOW FIRST RAIN WATER TREATMENT PLANTS FOR SURFACES FROM 600 TO 5000 SQM IPP/B SERIES WORK
The pollution produced by the meteoric water washing away process is essentially due to the presence of sand, mud and light mineral oils.
Water coming from different sides of the parking is sent to the flow rate dividing shaft in which thresholds (prepared according to the treated surface) separate the “first rain water” from the subsequent water, with a very diluted polluting charge and therefore apt for being sent to the by-pass treatment.

The parking lots subject to meteoric precipitations have to be suitably predisposed with a single water collection point in which the separator will be located.
The first rain water treatment starts into the sand separation section or sludge separation section for an optimal time allowing the sedimentable substances separation. This pre-treated water is therefore sent to the oil separation section, in which it undergoes a light substances fluctuation.

For the discharge water having to comply with the acceptance limits of the Directive 91/271/CEE there is the addition of a coalescence filter, a system allowing the microparticles adherence to a particular coalescent material (absorption effect) therefore increasing their dimensions (coalescence effect) and favouring their fluctuation to surface.
The separator discharge is automatically shut by a floating obstructor preventing oil spilling, when the latter reaches a certain level in the collection chamber.

USED MATERIALS
Tanks : highly resistant vibrated reinforced concrete
Shafts : D400 cast iron
Internal carpentry : AISI 304 stainless steel

SPECIFICATION
“Supply of a first rain water treatment plant type EURO MEC IPP/B series for the first rain water treatment by means of a by-pass, composed of highly resistant reinforced concrete tanks divided into three sections: a flow rate dividing section, a sand separation section and an oil separation section, complete with stainless steel deflectors, coalescence filter, floating obstructor, carriageable cover for heavy loads and D400 cast iron inspection manholes.”
