3 Clari-Trac -2 (CT2 ) Submerged Sludge Collector Arrangement

4 differential head to sludge disposal Graphic on Front of Brochure Illustrates the Principle of the CT2 Motion of header Gravity

5 Typical CT2 Installation---Plan View Pass Width Typically used in rectangular basins Maximum header width for single pass: 30 feet Guide rail (track) located near center of pass Preferred drive location: Influent end of tank

6 Typical CT2 Longitudinal Section 2 Vent with valve Pressure Head Water Level Sludge Discharge Maximum travel length for single header: 120 feet Sloped floor OK in one direction only Typical minimum pressure head: 5 feet

7 The double header is used only when applicable Double header used for tanks longer than 120 or for special coverage

8 We can cover all the basin sizes with multiple header systems, cost effectively No tank too small, no job too big

9 Clari-Trac-2 Fit & Forget Engineered Simplicity

10 Collection Header Guide Shoe (Carriage) Header carriage design minimizes hang-up on the trac, reduces friction to motion, which translates into less drive horsepower. Guide rollers lock on trac, to prevent disruptive derailments top rollers

11 Lock it on and let it fly Guide rollers lock on trac to Prevent derailment and reduces Friction to motion. Less HP

12 Simple Cable Drive - simple components - direct connections - solid bearings - rigid frame - self tensioning All moving parts are out of the sludge layer

13 CT2 Control System Features - Fully automatic system w/ manual backup - Various automatic cycle modes - PLC-based control platform - Easily integrated into a plant SCADA system - Integrated with process knowledge Benefits - Flexibility yields optimum process results - Sole responsibility for the unit process

14 Multi-pass Control Options for Optimum Sludge Removal Sludge Concentration Management Sludge is withdrawn evenly Sludge profile is followed to remove sludge only

16 CLARI-VAC PRINCIPLE OF OPERATION siphon valve siphon pipe forms structural header vacuum Pressure head float float Sludge trough structural pipe to support floats when drained down large orifice header to handle high solids

17 Clari-Vac Arrangement SKIMMER BLADE

18 Support System Float Beam Bridge Pipe

19 Suction Piping is Angled for Convergence of Headers To Provide Full Sludge Withdrawal From A Single Plane In The Tank

20 Clari-Vac is Self-Supporting

21 Hydraulic System Dense sludge discharge into sludge return channel in wastewater clarifier

22 Clari-Vac Application Range Rectangular Sedimentation Basins Width: 15 to 60 Length: up to 300 Drinking Water Southern States and warm climate areas surface ice is difficult to design for Wastewater Secondary Tanks on Activated Sludge All geographies can use as wastewater typically warm

23 Clari-Vac Units Low Disposal Costs -Heavier solids concentration, the result of removing solids directly from where they naturally settle, without pushing or plowing. Fast Removal - Up to 12 fpm. Reduced Maintenance - No moving parts underwater. All parts except drive are nonferrous. Energy Efficient - Up to 80% less power is required

24 Clari-Vac System Components Support System - bridge pipes, beams, floats Hydraulic System - collection header, pipe, valves Guidance System - guide wheels, tow bridle Drive System - drive, idler, tow cable Control System - control panel, switches Skimmer System - blade, mechanism, trip arms, scum trough, tipping weir Ancillary Equipment - vacuum pump, access platform, effluent troughs

25 Sludge Collector Systems - Summary CT2 Potable Water Submerged Collector Differential Head Metal Hydroxide Sludge 120 ft length x 30 ft width Clari-VAC Potable Water or Municipal Wastewater Floating Collector Siphon Action 120 ft length x 30 ft width Metal Hydroxide or Waste Activated Sludge 300 ft length x 60 ft wide
