Oil-separator

 

is a topic in many countries were the government is focused to avoid to much oil in the waste water from car washes.

I was at a meeting with one of the big player in car wash in our region. They have invest substantially in building new and improved oil separators but still there are car washes were they do not full fill the regulations.

The conclusion was that it has to be the chemicals.

I stated the difference between detergent and detergent.

Alkaline, petroleum and micro emulsions are all called detergents but they are totally different if you see them in a strict chemical point of view.

They also react differently in the oil separator, no questions about that. Micro emulsions are the biggest threat. Petroleum based detergents with emulsifiers is second then the ones without emulsifiers. Alkaline is the best from this  point of view.

Petroleum based detergents without emulsifiers has a big problem to penetrate the water film that is very common on cars in winter time.

We have added an additive to the detergent on the right side so it can penetrate the water film on the car so it will react and solve the contamination, read asphalt and tar, on the surface in a efficient way.

Our laboratory did a short film and the left detergent is a normal petrolium based with emulsifiers and the detergent to the right is without.

Some water is added first then the two different petrolium based detergents. The difference in speed of seperation between the two is huge.

 Herobiol Flash is the name of this new imporved product, to the right in the film, that could help many carwashes who has problem with the outgoing wastewater.
