Why filter hydrocarbon-contaminated water in industrial containment systems?

What are the risks of accumulating contaminated rainwater?

It is unavoidable: rain eventually fills outdoor storage areas. Allow water to stagnate, and your containment basin may overflow, carrying oils into the surrounding soil. Proper drainage of hydrocarbon-contaminated rainwater is therefore essential to protect your land and comply with environmental regulations. In addition, oil-contaminated water filtration helps prevent groundwater contamination, avoiding complex and costly decontamination projects.

Medium flow rate, pollutant blocking and operational safety

When facing changing weather conditions, drainage capacity makes all the difference. With a hydrocarbon filter with a flow rate of 16 l/min, you remain protected even during heavy rainfall on standard containment systems. But what happens in the event of a major leak? The polymer expands and blocks everything. Not a single drop passes through anymore. This provides a reliable mechanical safety mechanism to protect your entire industrial site.

Which PETRO PIPE® solutions are available for containment basins and pits?

Hydrocarbon filtration cartridge for pits and containment basins

Each site has its own configuration and therefore its own installation method. You may install a hydrocarbon filter for containment pits on a concrete structure or choose a filter for hydrocarbon-contaminated water in containment basins. In any case, the core system remains unchanged. It is the hydrocarbon filtration cartridge specifically designed to solidify the exact oil present in your equipment.

Kits, accessories and pre-filters to complete the installation

Hydrocarbon filtration cartridge for retention pits and bunds

Each site requires its own configuration and installation method. You may install a hydrocarbon filter for retention pits on a concrete structure or choose a filter for hydrocarbon-contaminated water in retention bunds. Whatever the configuration, the core technology remains the same. The key component is the hydrocarbon filtration cartridge specifically designed to solidify and retain the exact oil used in your equipment.

Kits, accessories and prefilters for a complete installation

Leaves, sand and mud can quickly clog drainage systems. This is where a prefilter for hydrocarbon cartridges becomes essential to stop debris and extend the service life of the main component. To simplify installation, we provide a fully ready-to-use hydrocarbon filtration kit for retention bunds. Shut-off valves, seals and filters are included for fast on-site installation.

How to choose the right oil-contaminated water filtration solution?

Choose according to the type of pollutant and required flow rate

Start by identifying the type of oil involved. Why? Because esters and mineral oils require different polymers to solidify within the filtration tube. Next, evaluate the surface area exposed to rainfall in order to estimate the volume of water to be drained. To avoid overflow during heavy storms, your filtration system for metal retention bunds must be correctly sized according to the rainfall conditions of your region.

Choose according to the installation: metal bund, concrete pit or industrial equipment

Equipment is not installed in the same way on a thin steel wall as on a solid concrete structure. To adapt to each configuration, Technikelec provides dedicated mounting plates and threaded fittings. Simply check the thickness of your wall and the available outlet diameter. This is the best way to ensure you select the correct product reference for a perfect connection.

What should be checked before installing a hydrocarbon filter?

Preparation of the connection area and sealing

A perfectly clean installation area is essential. Without reliable sealing, contaminated water may leak around the threaded connection and infiltrate the ground. Use Teflon tape or the supplied flat gaskets to ensure secure connections. A properly installed system guarantees that all water flows through the filter as intended.

Inspection frequency and component replacement

Which pollutants can be retained: hydrocarbons, oils, natural and synthetic esters?

Each industrial fluid has its own chemical characteristics. Whether used in electrical transformers or machine tools, oils vary significantly. This is why our systems manage filtration of water contaminated by natural esters with the same efficiency as filtration of water contaminated by synthetic esters. In practice, the technology adapts to fluid density and captures both conventional mineral oils and dielectric fluids before they reach the environment.

How does a medium-flow hydrocarbon filter work?

Gravity filtration and continuous drainage of contaminated water

Everything relies on gravity. Water simply flows through the hydrocarbon filter without electricity or lift pumps. The secret lies in the internal component that instantly reacts to oil. As soon as the filtration cartridge for hydrocarbon-contaminated rainwater comes into contact with the pollutant, it solidifies. The result: clean water drains through the bottom while pollution remains permanently trapped inside the polymer matrix.

Protecting your ground with the right industrial equipment

Meeting environmental regulations should never become a technical challenge. By choosing a mechanical drainage solution, you protect your transformers while reducing daily maintenance requirements. At Technikelec, we support this environmentally responsible approach with robust equipment designed for demanding field conditions. Choose simplicity for your facilities and let clean water safely return to the environment with complete peace of mind.

Frequently Asked Questions

Why install a hydrocarbon filter on a retention bund?

A hydrocarbon filter treats contaminated rainwater before discharge. It protects soil, prevents groundwater contamination and ensures compliance with environmental regulations. Technikelec solutions effectively secure industrial installations.

Which pollutants can be filtered?

These filters retain hydrocarbons, mineral oils and natural or synthetic esters. The technology adapts to different fluids to provide reliable filtration across a wide range of industrial equipment.

How does a hydrocarbon filter work without electricity?

The system operates through gravity. Water naturally flows through a cartridge designed to block pollutants. In the event of a major leak, the material solidifies and completely stops the flow.

How do you choose the right hydrocarbon filter?

The selection depends on the type of pollutant, the required flow rate and the installation type (bund, pit, etc.). Technikelec offers dedicated solutions with kits and accessories for simple integration.

What maintenance is required?

One or two inspections per year are generally sufficient: clean the prefilter and check that water flows correctly. If the cartridge becomes saturated, simply replace it.
