Rainwater filter system - 5L/min & 15L/min

Reference: FILTRELEC ECODESIGN®

Description:

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:

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

Installation

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.

INNOVATION! FILTER WITH REPLACEABLE CARTRIDGE - FILTRELEC F5®

Installation

AKHELEC dimensions the type, number and location of the systems designed to filter oil -polluted rainwater. All solutions depend on the retention volume and rainfall recorded in the region in which the installation is located.

The engineering of the most complex systems is performed by our design office in order to offer you a comprehensive solution. Concrete pit, fire-protection system, rainwater disposal or even filtering of drainage water.

Longer lifespan: the filters only need to be replaced when they are saturated with hydrocarbons.

Waste treatment: as an option, a « PC Back » unit is available, which recycles and treats the saturated filters so that they can be correctly disposed of at a waste collection centre.

50% less waste

Filters used on electrical transformer containment bunds used to be single-use filters: once saturated with oil, the filter had to be replaced with a new filter. Whereas the FILTRELEC F5 system comes with a repleacable cartridge: the filter cartridge just has to be changed.

At a time when environmental challenges are more relevant than ever, the FILTRELEC® F5 system is a fully ecodesigned product. Environmental considerations are taken into account from the design stage with the aim of reducing the impact on the environment throughout the life cycle of its products.

This allows for a 50% reduction in the volume of waste produced compared to a conventional filter.

Use

FILTRELEC ECODESIGN® is a range of rainwater filtering products. It allows for continuous disposal of water. And, at the same time, absorbs the harmful hydrocarbons, thereby preventing ground pollution.

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

The widest range of filters on the market: can handle all mineral, plant and silicone oils.

More efficient than a conventional filter

Less time-consuming, as the cartridge can be changed in just a few minutes, on-site, by following a few simple steps. Less expense, as only part of the filter system has to be replaced.

Designed and manufactured in France using material that is resistant to UV rays and extreme temperatures, our system for filtering hydrocarbon-polluted rainwater is also more robust than conventional filters and therefore has a longer life span.

An efficient way of protecting the environment

This filter is intended for users of high-voltage electrical transformers. This is because power transformers contain a significant quantity of oil, usually mineral oil, which is non-biodegradable. 

In addition, in the event of an oil leak, the rainwater dripping down the walls becomes impregnated with hydrocarbons and can pollute the atmosphere, especially ground water. To limit this risk, electric power substations are fitted with oil recovery systems. These systems usually comprise containment bunds or retention pits fitted with oil absorbent water filters.

3 functions that ensure compliance with the Water Act

The FILTRELEC® system performs 3 retention-related functions:

  • Constant disposal of rainwater
  • Permanent absorption of hydrocarbons
  • Instantaneous shut-off in the event of a massive hydrocarbon leak.

At the filter outlet, the purified water contains less than 5 mg of hydrocarbons per litre of water: in compliance with the Water Act.

Meets the requirements of the Water Act at a managed cost. Our filters, which are compliant with the Water Act, permanently absorb the harmful hydrocarbons present in the oil-polluted water. This prevents pollution of ground water and soil.

Made in France

Product range developed in partnership with  TOTAL and Institut Français du Pétrole Energies Nouvelles. FILTRELEC® filters comprise 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.

Our technology has been approved by the major certification bodies: TÜV (test report 73068874 TPI 001), SGS (RES 142458.Rev1), Bureau Veritas (C-151215 -12187_Rev02).

Filtering of water and oil in containment bunds housing the electrical  transformers

50% less waste compared to a conventional rainwater filter. 100% French quality. Long life span, reduced maintenance. Our teams, which are at the forefront of innovation, have created a rainwater filter system that can be replaced on-site, is eco-designed and uses materials that are resistant to UV rays and extreme temperatures.

This system only requires the filter cartridge to be replaced when saturated instead of the whole filter unit.
