WaterBoy Flow Diagram

WaterBoy Features Coagulation, flocculation, 7 1/2° tube settling and mixed media filtration Completely pre-assembled single tank units in sizes up to 60 gpm Standard sizes WB-14, 27, 82 and 133A Standard flows 10, 20, 60 and 100 gpm Clarification based on equivalent settling surface area of 100 gpm / ft2 Detention time in flocculator - 10 minutes

Microfloc WaterBoy™

WaterBoy Process Operation Backwash Flow set with influent valve or float Filter level float valve Chemicals added upstream of tank Flash mix and one flocculation stage Flow up through tubes and down through filter Water pumped to storage Filter headloss starts backwash (vacuum) Drain siphon primed Tubes siphon drained Backwash pumped through filters and tubes Drain siphon broken Tubes filled with clean backwash and placed back in operation

WaterBoy Application For water temperature above 50° F Up to 200 NTU Up to 100 true color Up to 10 mg / L iron Up to 5 mg / L manganese For water temperature below 50° F, reduce above criteria by up to 50 % Higher solids loading than Tri-Mite Lower solids loading than Aquarius

WaterBoy Sweet Spots Treats surface and ground waters Size permits portable installations on skids and trailers Ideally suited for small communities, low flow industrial applications, resorts and recreational sites Over 300 installations
