Biological Utilization of Hydrocarbons

Treatment of industrial sludge commissioned by a bio-remediation company

​

Coal tar is a thick black liquid which is a by-product of the production of coal gas and coke (fuel). It contains benzene, naphthalene, phenols, aniline, and many other organic chemicals. Coal tar is used for medical and industrial purposes. However, coal is also known as cutar, balnetar, liquor carbonis detergens, liquor picis carbonis, etc.

Coal gas is a mixture of gases i.e. hydrogen methane, carbon monoxide and volatile hydrocarbons procured by the destructive distillation of coal. It is a flammable gas and is made from coal which is supplied via a piped system and is obtained from coal in the absence of air and contains nitrogen and carbon dioxide.

For this project we cleaned coal tar sludge using Constructive Microbes.

​

The process of utilization consisted of:

• collecting of sludge in a tank with closed circuit

• applying Constructive Microbes to the sludge via the action of water streams

Below are the results of the analysis made before and after treatment with Constructive Microbes.
