Abstract:
1. A package chemical/mechanical dewatering sewage treatment method for wastewater inflow streams, which can be chemically dewatered by the injection of sulfur dioxide to separate solids from wastewater comprising: a. injecting a supply of sulfur dioxide into the wastewater inflow streams, b. holding the sulfur dioxide-treated wastewater for the dwell time required to partially agglomerate the solids, and c. depositing the sulfur dioxide-treated partially separated wastewater onto at least a drain pad including filtration means structured to receive the sulfur dioxide-treated wastewater and separate the solids from the sulfur dioxide-treated wastewater liquid fraction for disposal or capture, the drain pad structured to hold the separated solids until the desired chemical dewatering has occurred.
