Patented filtration system belonging to the technology SPI® the SPI natural ESTER range for MIDEL EN and FR3 COOPER is the United Kingdom and European reference rainwater filter for hydrocarbons contaminated waters in small retention volumes.

The range SPI for natural Esters type MIDEL EN or FR3 COOPER is composed by a set of rainwater filter cartridges designed to drain rainwater in hydrocarbons retention  bund, metallic retention tanks or small concrete pit.

Easy to install thanks to its KIT to any existing valve or concrete bund.

Use horizontal or slightly inclined in direction of the flow.

The only filter on the market recognized from more than 10 years by the biggest UK and European industry (Network rail, Balfour Beatty, ABB, SIEMENS, SCHNEIDER…) and having passed successfully the test by independent laboratories such as Bureau Veritas or TUV with a hydrocarbons rate in output of the filter below 5 ppm.

An external pre-filter is strongly recommended to limit the clogging of the internal filter by impurities in the water (sludges and organic matters). Either using a prefilter to screw on the filter head (PFC44) or a pre-filtration PFBS box fixed in the tray. In all cases, the pre-filter must be regularly cleaned with clean water, in order to maintain a maximum treatment flow.Several filters can be connected in parallel in the event of higher flow rates.

Thanks to its active component, the SPI® ester filters filter rainwater and retains the traces of esters, thus avoiding that the tanks are transformed into real swimming pools.
 
During a major spillage of the ester, the component reacts and instantly forms an airtight stopper, resistant up to 1 bar pressure, preventing any fluid from flowing into the environment.
 
In all the cases tested, the ester concentration of the water at the filter outlet is less than 5 ppm.
