Conclusion<br />
1. Project is currently under construction and will come<br />
online by June of 2014<br />
2. CFD helped us understand clarifier failure mechanism<br />
but no cost effective improvements found<br />
3. <strong>Wet</strong> we<strong>at</strong>her flows receiving secondary tre<strong>at</strong>ment will<br />
be maximized by:<br />
– Incorpor<strong>at</strong>ing step feed for normal oper<strong>at</strong>ion and two wet we<strong>at</strong>her<br />
oper<strong>at</strong>ing modes<br />
– Addressing sludge settleability issues and providing tools to<br />
maintain well settling sludge<br />
– Implementing a high degree of autom<strong>at</strong>ion to accommod<strong>at</strong>e the<br />
highly dynamic winter time flows and simplify tre<strong>at</strong>ment plant<br />
oper<strong>at</strong>ion<br />
