What is it?
The GPC Filter Process incorporates a specially constructed sand filter added after the denitrification step at wastewater treatment systems with flow up to 100,000 gallons per day. The GPC Filter Process is unique in that a dissolved carbon is added to already treated wastewater and is then dosed to the specially constructed sand filter.
What does it do?
Water passing through the GPC Filter Process has concentrations of Five Day Biochemical Oxygen Demand (BOD5) that are often Below Detection Level for laboratory testing procedures.
Water passing through the GPC Filter Process has concentrations of Total Suspended Solids (TSS) that are often Below Detection Level for laboratory testing procedures.
The GPC Filter Process reduces concentrations of Total Nitrogen by over 50%.
The GPC Filter Process reduces the concentrations of almost all organic Contaminants of Emerging Concern in the water passing through.
The GPC process will reduce permit non-conformities in the operation of a wastewater treatment facility.
What is it for?
A GPC Filter Process can be added to any existing or proposed wastewater treatment facility approved under a Ground Water Discharge Permit up to 100,000 gallons per day.
A GPC Filter Process can be added to any existing or proposed wastewater treatment facility approved as an Alternative Innovative Denitrifying Septic system under Title 5 from about 1,000 gallons per day up to 10,000 gallons per day.
Who is it for?
This system will benefit owners, engineers and operators of wastewater treatment systems as a GPC Filter Process will discharge more highly treated water and minimize times when the discharge does not meet permit requirements.
This system benefits all of us as a GPC Filter Process will better protect our environment.
Why is it better?

Provide support and answer questions
This Filter has been shown to remove nearly 53% of dissolved nitrogen from denitrified wastewater effluent.
