Draining Rainwater Contaminated with Hydrocarbons Safely with SPI

How can large volumes of water potentially contaminated with dielectric oils be discharged without electricity while complying with environmental regulations? Since the 1990s, SPI has addressed this challenge with an innovative technology: filters capable of solidifying hydrocarbons and ensuring the safe drainage of retention tanks and fire-extinguishing pits beneath electrical transformers.

Exclusive SPI Technology: Three Essential Functions

• Continuous Rainwater Drainage: Allows safe gravitational flow without mechanical intervention.
• Hydrocarbon Filtration: Captures traces of emulsified or dissolved hydrocarbons in the water.
• Solidification upon Saturation: Locks hydrocarbons within the filter by solidifying internal components, preventing any accidental leakage.

A Global Leader in Filtration Solutions

For three decades, SPI has provided the most comprehensive range of anti-hydrocarbon filters on the market, offering both standard products and bespoke solutions for various applications:

• Simple, fire-resistant, or flexible retention tanks and pits
• Long-term storage areas
• Underground tanks, car parks
• Remote pits and other firewater retention basins

Key Products in the SPI Range

• PETRO PIT & PETRO PIPE: Simple cartridges for small and medium-scale retention.
• PETRO BARRIER and STORM BARRIER: Solutions for large volumes, gravity pits, or remote pit outlets.
• PETRO BARRIER PUMPED (PTB) and PETRO PIPE PUMPED (PTP): Pumped discharge via SPI filters.

Universal Compatibility

SPI filters are effective with all types of hydrocarbons, including:

• Dielectric oils
• Mineral oils
• Natural or synthetic esters
• Petrol, diesel, jet fuel

With SPI, you choose a proven and reliable technology, ensuring efficient management of contaminated rainwater and optimal environmental protection.
