Cartridge filtration system PETRO-BARRIER

for wateroil

The PETRO BARRIER™ is an in-ground system specifically designed to provide continuous drainage filtration with 100% retention of hydrocarbons released from transformers. The PETRO BARRIER™ is a product designed to easily fit into your pit drains or in remote pit outlets. Designed and developed in the 1990's the PETRO BARRIER, consists of a corrugated HDPE pipe that can expand to the desired reference in diameter and depth. The PETRO BARRIER is sunk or embedded vertically at the level of your low point of the polluted water drainage. The PETRO BARRIER is made up of 3 distinct sub-components, or chambers: - The upper part of the PETRO BARRIER, through which the fluids (water, dielectric oils, or hydrocarbons) pass, called the inlet chamber, is made up of several filters and anti-debris pre-filters to prevent the active part of the PETRO BARRIER from clogging. - The secondary chamber, or active anti-hydrocarbon filter, is made of aluminum. This cartridge acts as a hydrocarbon separator and is made of a hydrophobic and oleophilic material that saturates and solidifies when in contact with oils and hydrocarbons, but also natural or synthetic esters. - The lower part, or evacuation chamber, recovers the clean water at the filter outlet, to evacuate it towards your EP network or directly into the environment. In fact, in all our tests for over 30 years, the water leaving the SPI filters has a hydrocarbon concentration of less than 5 ppm. More information on our website www.sanergrid.com
