Soil and Groundwater Remediation

Soil and Groundwater remediation projects often call for treatment of groundwater, soil vapor extraction condensate, soil vapor and other liquid and vapor streams for removal of volatile and semi volatile organic compounds. Carbonair has provided thousands of STAT Low Profile Air Strippers, liquid phase and vapor phase carbon vessels for remediation systems over our 30 plus years in business.

Carbonair designed and supplied two 1,000 gpm STAT 720 low profile air strippers operated in parallel to treat rock quarry water that had low concentrations of dissolved TCE. The groundwater from nearby plume migrated into the base of a rock quarry that required dewatering and treatment during the clients rock crushing activities within the rock quarry.

 

 

Municipal Drinking Water Treatment

Municipalities are often faced with VOC contamination of their source wells. Chemicals like Vinyl Chloride and Trichloroethylene can leach into aquifers used as source water for municipal wells. When this occurs, in many cases the most cost effective solution is to treat the water to remove the VOCs using air stripping, which has been established as a Best Available Control Technology BACT for this application. This challenge has grown recently with the promulgation of new regulations lowering the levels of Disinfection By Products allowed in municipal drinking water. These byproducts, called Trihalomethanes or THMs, can be effectively removed with Carbonair’s STAT Low Profile Air Strippers. Other contaminants effectively removed by STAT Low Profile Air Strippers include Vinyl Chloride, Trichloroethylene and Benzene. When treating these compounds in municipal drinking water, Carbonair’s STAT Low Profile Air Strippers can often treat the water more cost effectively than the more commonly used granular activated carbon systems.

This project include the use of three STAT 720 low profile air strippers operated in parallel to remove dissolved Vinyl Chloride from three municipal drinking water wells.  The maximum flow rate from each well was 1,000 gpm.  Carbonair supplied the low profile air strippers, hurricane hold down equipment, blowers and master control panel with Variable Frequency Drives, automatic airflow control transmitters, acoustical cladding for blowers and acoustical enclosures for the blowers due to the close proximity of homeowners near the treatment system.  A PLC was provided to provided automatic distribution of incoming water to one, two or all three air strippers dependent on how many wells needed to be operated based on the call for water.

This project included the use of one STAT 720 low profile air stripper to treat one municipal well with TCE contamination.  The unit is operated at an approximate liquid flow rate of 900 gpm based on the call for water from the municipal water system.  Carbonair provided a design for a machine cover enclosure with removable roof for access to the treatment equipment demister and trays.

 

Industrial Wastewater Treatment

Industrial process and wastewater can contain volatile organic compounds (VOCS) that can have a negative effect on the production process or downstream waste water treatment processes.  In these instances, it is often necessary to put treatment equipment in place to remove the VOCs.  Carbonair’s STAT Low Profile Air Strippers are often an ideal solution to this problem.  Carbonair has provided several of our STAT Low Profile Air Strippers for the treatment of Industrial wastewater.

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 waste water stream to acceptable discharge limits prior to discharge.  The system operated at a maximum flow rate of 3,000 gpm with automatic controls.
