Fills large vessels treating pumped groundwater or vapour.
Long-lasting carbon filters used to clean up massive underground pollution spills over many years.
Fills large vessels treating pumped groundwater or vapour.
Coal for high volumes, coconut for stubborn trace chemicals.
Built to run unattended for months between changeouts.
These filters run 24/7 for years, so reliability is everything.
Cleaning up a chemical spill is incredibly slow. As the years go by, the amount of pollution coming out of the ground slowly drops. The carbon filters must be designed to handle these slow changes. We also use a smart "two-tank" system to ensure that even while we swap out the old carbon, the filtering never has to stop.

Proves the carbon can catch the tiny chemical molecules commonly found in toxic spills.
The carbon is one stage in a train, not the whole of it.
We test the dirt and water to find out exactly what was spilled, how much there is, and how many years it will take to pump it all out.
We install basic sand or mesh filters first. This catches normal dirt, rust, and mud so they don't instantly clog the expensive carbon.
The toxic water or air flows through two carbon tanks in a row. The first takes the hit, the second acts as an absolute guarantee of safety.
When the first tank is full of toxins, we safely remove it. The second tank becomes the new first tank, and a brand new tank goes in the back.
The grades that fit soil remediation — and what each is good at.
Coal based · Coconut shell
Used when pumping contaminated water out of the ground. The water flows through large tanks of this carbon before being safely returned to nature.
Granular · Pelletised
Used when vacuuming toxic air out of the soil. It traps the chemical fumes before the air is blown out into the sky.
What each property actually governs once the bed is running.
A strong score ensuring the carbon can catch the small, slippery chemicals common in industrial spills.
Needs to be sized perfectly so the pumps don't have to work too hard to push the water through over the years.
Must survive months of constant water flow and occasional backwashing without breaking down into dust.
We pump the toxic water or air out of the ground and push it through giant tanks of carbon. The carbon traps the toxins, and clean water or air comes out the other side.
Safety and money. If you have one tank and it gets full, you start pumping toxic water into nature. With two, the second tank acts as a 100% safety net while letting you completely use up the first tank.
It is almost always normal dirt, rust, or bacteria from the ground blocking the carbon, not the toxic chemicals! You must put a basic dirt filter in front of the carbon tank.
Send the stream analysis and the operating conditions, and we will come back with the grade, the bed size and the changeout interval the duty actually needs.
