Evoqua's Carbonair’s STAT low profile air strippers are an ideal solution for removing VOCs in wastewater
Challenge
Industrial process and wastewater can contain volatile organic compounds (VOCS) that can have a negative effect on the production process or downstream wastewater treatment processes. In these instances, it is often necessary to put treatment equipment in place to remove the VOCs. Evoqua's Carbonair’s STAT Low Profile Air Strippers are often an ideal solution to this problem. Evoqua's Carbonair has provided several STAT Low Profile Air Strippers for the treatment of Industrial wastewater.
Solution
This project included the use of three STAT 720 low profile airstrippers operated in parallel, each operated at a maximum flow rate of 1,000 gpm, to remove approximately 1,100 ppb dissolved Vinyl Chloride from an industrial manufacturer wastewater stream to acceptable discharge limits prior to discharge. The system operated at a maximum flow rate of 3,000 gpm with automatic controls.
Results
Evoqua's specialty media effectively reduced the wastewater cadmium level current permit requirements and allowed the customer to avoid penalties for non-compliance.
Treatment using the Evoqua specialty media provided cadmium removal to below the desired permit levels without the need for additional pH adjustment, thereby saving the customer the cost for additional chemical preparation and also, eliminated concerns associated with chlorine damage to the media.
