Designing Waste Treatment Systems for Laboratories

Designing Waste Treatment Systems for Laboratories

The system design becomes critical. Since it is impossible to predict what chemicals will be used in the lab and often in what quantities, sizing a centralized or local waste treatment system is difficult. For years, limestone has been the treatment choice for laboratories. Limestone is an excellent neutralizer and is still common in small systems.
