99% of Interceptor Contamination Remediated

What is an Interceptor Tank?

An interceptor tank is a trap used to filter out hydrocarbon pollutants from rainwater runoff. It is typically used in road construction and on petrol station forecourts to prevent fuel contamination of the water table via runoff.

Petrol interceptors work on the premise that some hydrocarbons such as petrol and diesel float on the top of water. The contaminated water enters the interceptor typically after flowing off roads or forecourts and entering the first tank inside the interceptor. The first tank builds up a layer of the hydrocarbon as well as other scum. Typically petrol interceptors have 3 separate tanks each connected with a dip pipe. As more liquid enters the interceptor the water enters into the second tank leaving the majority of the hydrocarbon behind as it cannot enter the dip pipe, whose opening into the second tank is below the surface. However some of the contaminants may by chance enter the second tank. This second tank will not build up as much of the hydrocarbon on its surface. As before, the water is pushed into the third tank and more water enters the second. The third tank should be practically clear of any hydrocarbon floating on its surface. As a precaution, the outlet pipe is also a dip pipe. When the water leaves the third tank via the outlet pipe it should be contaminant free.

Cleaning Interceptor Tanks

Interceptor tanks have to be emptied regularly of the build-up of hydrocarbons, under new stringent environmental regulations. Leaks from such tanks can have catastrophic effects on land surrounding the tank and also the water table. The emptying of these tanks is a costly exercise, and the hydrocarbon pollution is simply moved elsewhere to be treated with chemicals and other detergents.

Nanobite Powder is the European trade name for a bio-remediation accelerator known as PRP (Petroleum Remediation Product) in the USA. Nanobite Powder, an award winning NASA product, is made from powdered bees wax spheres, and is designed to absorb and remediate spilled oil, diesel and petrol on water and on land.

Nanobite Powder is used for the bio-remediation of hydrocarbon spills, or leaks. It is made from completely natural products – the base product being bees wax – is inert and non-toxic. Nanobite Powder is an all natural hydrocarbon absorbent that attracts and stimulates the natural microbial population to degrade oil on land or water.

Nanobite Powder consists of tiny spheres of treated bees wax, which contain nutrients. When a wax sphere comes in contact with spilled oil, it “binds” with or “encapsulates” the hydrocarbons. Nutrients in the bees wax sphere help micro-organisms (microbes) from the immediate environment to grow very rapidly in number – a greenhouse effect. These microbes eat every droplet of the hydrocarbons, breaking them down into the constituent parts – CO2 (carbon dioxide) and H2O (water). Nanobite Powder will absorb and remediate, over time, more than 20 times its weight in hydrocarbons.

Bioremediation stages

Results: Tests performed on interceptor tanks using Nanobite powder booms (1m, 2m or 3m socks with Nanobite Powder) placed in the interceptor have proved to be a complete bioremediation solution with up to 99% of hydrocarbons remediated.
