Immediately stop using inappropriate treatment products. NSF-listed units are only for residential strength wastewater applications. a. Use a high-strength treatment product or process to pretreat the wastewater, bringing the wastewater strength down to residential strength. Then, and only then, can you use 30TAC285 for the design of the balance of the OSSF. 2. For all non-residential strength applications, use the design approach presented by <strong>TOWA</strong>’s high strength wastewater workshop. a. Quantify Q by determining maximum fl ow, minimum fl ow, and average fl ow – hourly, daily, weekly, monthly, even annually (schools). b. Quantify infl uent wastewater strength parameters i. BOD, CBOD ii. TSS iii. pH iv. FOG v. Temperature c. Determine effl uent wastewater strength parameters Jeff Snowden NSF Listed Treatment Units, ONLY for Residential! d. Select a treatment and disposal process appropriate for the above conditions and for the site-specifi c conditions. 3. The Designer must state in writing the assumed infl uent Q, BOD/CBOD, TSS, pH, FOG, Temperature, and any other criteria, such as nutrients, if applicable, and must state, in writing, the effl uent values that the design is intended to achieve. 4. The Regulatory Agency must condition the permit on achieving the effl uent values required by the rules or permit. For restaurants, the renewal of the food license should be conditioned on continual compliance with the OSSF permit. <strong>TOWA</strong> <strong>TOWA</strong> <strong>Insider</strong> 3
