An acid
neutralization system treats the discharge from the semiconductor wet
process fabrication facilities, as well as other industrial processes, to make
the liquids environmentally safe for disposal.
The right system for an application will add alkaline
chemicals to the acidic solution and increase the pH close to the neutral
reading of 7, while recording process data to ensure regulatory compliance. If
the acid is untreated, releasing it would be environmentally hazardous and
pollute waterways. Governments have imposed regulations on the procedures
required to dispose of industrial waste.
An acid neutralization system treats and measures the acidity of wastewater as it exits the production line. Depending on the process, a suitable neutralizing chemical is added to reduce the acidity. The sensors verify that the pH level of the wastewater has been reduced due to neutralization. That pH level should be in compliance with the applicable government regulations before the liquid can be released.
Depending on the type of operation, an acid neutralization system can be selected in either continuous flow or in batches:
1) Continuous flow neutralization
This applies to the continuous flow acid neutralization systems which have a continuous addition of neutralizing chemicals. There is only a slight variation that is easily controlled and monitored. The flow can be from a few gallons to several hundred gallons per minute. Discharges and their characteristics are recorded on a digital chart recorder.
2) Batch neutralization
In this type of neutralization system, the batches of waste chemicals often need extensive treatment and may require different neutralizing chemicals to meet the allowed discharge pH levels. The system takes the pH level reading and then adds the necessary chemicals to verify the correct pH level has been reached.
Modutek’s acid neutralization systems are fully automated and are available in batch neutralization or continuous flow designs. The compact design allows these systems to fit into available space and can be customized for specific applications.
