3. I E Industrial Equipment Servicing the North State Environmental Cleaning Systems Elements of Pretreatment (Summary) Washpad Design  Slope to Center Drain  Slope to Side or Corner (IE Design) Water Collection  Center Drain  Large Ramp Drive-in Trough  Solids Trough w/removable weirs and Sump (IE Design) Oil & Solids Separators  In Ground Separator  Above Ground Cone Bottom Separator (IE Design)

4. I E Industrial Equipment Servicing the North State Environmental Cleaning Systems Elements of Pretreatment Washpad Design  Slope to Center Drain  Slope to Side or Corner (IE Design)

5. I E Industrial Equipment Servicing the North State Environmental Cleaning Systems Washpad Design Problems:  Solids flow into drain. Slope to Center Drain

6. I E Industrial Equipment Servicing the North State Environmental Cleaning Systems Solids stay on wash pad for easy clean up! Drive over berms (Containment) Washpad Design Slope to Corner (IE Design)

7. I E Industrial Equipment Servicing the North State Environmental Cleaning Systems Elements of Pretreatment Washpad Design  Slope to Center Drain  Slope to Side or Corner (IE Design) Water Collection  Center Drain  Large Drive-in Ramp Trough  Solids Trough w/removable weirs and Sump (IE Design)

8. I E Industrial Equipment Servicing the North State Environmental Cleaning Systems Water Collection Problems:  Floating oil is not readily skimmed off  Solids build up and need to be cleaned. Center Drain

9. I E Industrial Equipment Servicing the North State Environmental Cleaning Systems Water Collection Problems:  Hard to manage  Large amounts of oils and solids need to be dealt with at one time  Requires tractor and several laborers to clean. Large Drive-in Ramp Trough WashpadTrough

10. I E Industrial Equipment Servicing the North State Environmental Cleaning Systems Solids Trough As Waste Water Flows down the trough, solids settle out for easy removal. Removable Weirs slow down water to let solids settle out, as well as allowing quick and easy cleaning. IE Design Lava Rock Basket for finer solids removal

13. I E Industrial Equipment Servicing the North State Environmental Cleaning Systems In Ground Separator Positives Negatives Uses little above ground space Out of Sight - Out of Mind Solids Build up Decreases Effectiveness Requires Contracted Pumping Service Pumping consists of both water and sludge Leaks are hard to detect

14. I E Industrial Equipment Servicing the North State Environmental Cleaning Systems In Ground Separator Theory Capacity: ~ 600 gallons Solids and Oils settle out as water sits in separator Actual (Typical) Capacity: ~ 10 gallons No Solids or Oils Separation

15. I E Industrial Equipment Servicing the North State Environmental Cleaning Systems Above Ground Separator Positives Negatives Settled solids are readily removed No pumping service is required Great arena for coagulation or bioremediation Leaks can be detected Uses above ground space Slightly more expensive than in ground separator
