Steam ,stripping,, also known as steam distillation, is an affordable, one-step solution to cleaning volatile organic compounds (VOC) from plant ,wastewater, streams. Typically, ,wastewater, feed streams enter a distillation column at the top and flow downward, while steam enters the column at the bottom and rises.

The treated ,wastewater, is then withdrawn from the treatment zone for further processing, such as ,stripping, of SO 2, ,neutralization,, and aeration. An advantage of using ,acid, to reduce the pH of the ,wastewater, instead of relying upon the SO 2 to reduce the pH of the ,wastewater, is that much less SO 2 is required to achieve disinfection.

Neutralisation : too acid or too alkaline, wastewater, flows are, neutralized, until a pH value of approx 7 is reached. The main reason to neutralize wastewater is to prepare it for further treatment in a biological wastewater treatment station or to meet the standards for discharge (eg. too acid wastewater can damage the sewer system and wastewater treatment plants).

For ,neutralization, treatment, the principle of treating waste with waste should be considered first. Such as ,acid, and alkaline ,wastewater, neutralize each other or use waste alkali (slag) to neutralize acidic ,wastewater,, use waste ,acid, to neutralize alkaline ,wastewater,. In the absence of these conditions, a neutralizing agent can be used.
