Treatment System Configurations This section shows the three most common treatment system configurations using an AdvanTex Treatment System.Determination of the appropriate con- figuration is based upon flow,primary treated effluent constituent concentrations,and discharge permit requirements. Each configuration shows the applicable treatment stages utilized and where to find the information to properly size the systems. For systems with restaurant waste contributions,adequate grease tankage or similar means are necessary to ensure that the maximum grease contribu- tion to the secondary treatment system does not exceed 25 mg/L greases and oils.Levels above 25 mg/L will tend to clog the textile sheets prematurely, preventing adequate aeration and uniform delivery of wastewater constituents for effective biological breakdown. The appropriate sizing equations are referenced in each figure.When multiple equations are referenced,each calculation should be performed and the largest resulting textile surface area must be used in the design.Please contact Orenco or the nearest Orenco Dealer for support regarding the appropri- ate configuration or sizing criteria.
