EAD Entrained Air Diffuser for Municipal Wells
A purpose-built stack of perforated rubber discs designed to keep air from reaching municipal well pumps, with a linked workstation for sizing each installation.
- For
- Municipal well operators and water-system engineers
- Worth noticing
- The page says the discs cannot reduce average annular downflow velocity or address air entering below the pump intake.
Field notes
The design process starts with casing, column, water-level, flow, and pump inputs, then considers disc count, placement, and perforation patterns. The page says its workstation ranks standard hole sizes against flow loss, cutting, and fouling, and provides a live well cutaway, hydraulic and risk analysis, a printable PDF, and true-size DXF files. Installation is described as bolting and tack-welding segments around the column. It also states that discs cannot address air entering below the intake.
