Filtration of hydrocarbon-polluted rainwater in the containment bunds under electrical transformers. Filters that guarantee contamination level of discharged rainwater <1 mg or 5 mg per litre depending on the model. New range: cheaper, more efficient, the widest range on the market.

Three additional functions for containment bunds

1. Continuous disposal of rainwater
2. Hydrocarbon absorption: water contamination at filter outlet < 5 mg
3. Instantaneous shut-off in the event of an abundant hydrocarbon leak

Design
This system, designed to filter hydrocarbon-polluted rainwater, works by gravity and is designed and assembled in Europe. It comprises an oleophilic and hydrophobic polymer that permanently absorbs the hydrocarbons.

In the event of an oil leak, this polymer reacts and forms a plug, thereby preventing any liquid from leaking into the environment.

An external pre-filter is needed to reduce the risk of premature clogging of the filter caused by dust and sediment contained in the hydrocarbon-polluted water, as well as a safety siphon.

Available models
F5: flow rates of up to 5 litres/min,
F15M2: flow rates of up to 15 litres/min (screw or seal type),
F100: flow rates of up to 100 litres/min (fixed or mobile),
F ULTIME: flow rates of up to 1500 litres/min.

NEW! F5 is a filter with repleacable cartridge! More information below about our rechargeable filter for oil-polluted water.

Insttalation
Our FILTRELEC ECODESIGN® rainwater filter system must be fitted to the disposal valve. For bigger flow rates, several filters can be fitted in parallel.

To avoid premature clogging, we recommend using a pre-filtering system (screw-on external pre-filter, metal pre-filter unit, etc.).

Main advantages
Large filtering capacity
Takes up little space
Oleophilic and hydrophobic polymer: permanently absorbs the hydrocarbons

Use
FILTRELEC ECODESIGN® is a range of rainwater filtering products that ensure compliance with the Water Act. It allows for continuous disposal of water and, at the same time, absorbs the harmful hydrocarbons, thereby preventing ground pollution.

AKHELEC offers a full range of solutions for capturing dielectric mineral oils contained in electric transformers based on the required flow rates.
