1 RESULTS OF ECOSYSTEMS PLUS INJECTION IN SECONDARY AERATION LAGOONS GLOBAL FOOD MANUFACTURER (SEPTEMBER )

2 PRIMARY PROJECT OBJECTIVES: Demonstrate ESP 's ability to increase the transfer of dissolved oxygen into the secondary aeration lagoons. A baseline of DO measurements was established for the period 8/17-23/06 in both lagoons 2&3. The levels were measured daily at 5 separate points along the length of each lagoon.the points were: o o #1-Influent distribution box. #2-The beginning of lagoon. o #3-Midway point. (Opposite surface aerator #1). o #4-End of the lagoon. (Opposite surface aerator #2). o #5-Effluent discharge box.

6 TECHNOLOGY BREAKTHROUGH GREATER AERATION EFFICIENCY: Improves oxygen transfer and uptake. Reduces energy use, while increasing DO. Increases biological activity and biomass. Increases treatment plant capacity. Reduces volatile organics for odor control. Improves nitrification and de-nitrification cycle.

7 TECHNOLOGY BREAKTHROUGH SOLUBILIZATION OF LIPIDS: Solubilization of fats, oils, and greases (FOG s). This is an accelerated natural catalytic process in which lipid ester bonds are rapidly cleaved, reducing their molecular structure to both glycerol and fatty acids. Glycerol and fatty acids are then readily available to wastewater micro-organisms as a high-energy food source of carbon for enhancement of nitrification and de-nitrification reduction processes.

8 STUDY PARAMETERS: (DISSOLVED OXYGEN TESTING) Since the RAS could not be separated, it was not possible to isolate Lagoon #3 and #2. Increases in DO were examined and compared as a combined total for lagoons #2 and #3. The ON and OFF time periods are both compared against the baseline.

9 SECONDARY CHANNEL FLOWS: The average daily influent flow from the anaerobic bio-reactor is.75 MGD, and this flow is split into two (2) influent flows of.365 MGD to the aerobic lagoons #2 and #3. These secondary aeration lagoons have a volume of 1.5 million gallons each. Each aeration lagoon has two (2) surface aerators, along with six 6 sub-surface, finebubble, air diffusers.

10 SECONDARY CHANNELS LOADING: Average return activated sludge (RAS) flow, per-lagoon, is.144 MGD. Baseline average daily loading was 10,677 lbs. TCOD. Average daily loading during study (9/6-22/06) was 14,818 lbs. TCOD.

11 STUDY START-UP: EcoSystems Plus was injected into the #3 lagoon influent distribution box: 3.6 GPD. The results of increased DO levels (9/6-22/06) are compared against various baselines.

12 STUDY TESTING: NH 3 -N and TCOD levels, sampled at the clarifier discharge point, were compared against historic baselines. Final sludge volumes from dewatering were compared against a baseline. PO 4 -P Removal Rates were compared as well.

13 RESULTS IN SECONDARY AERATION LAGOONS: (DISSOLVED OXYGEN) 45% increase in DO measured at the lagoon discharge point: study period 9/6-22/06, against baseline period 8/17-23/06. Surface aerators both on and off. Concurrent with 39% increase in TCOD loading, over baselines.

14 RESULTS IN SECONDARY AERATION LAGOONS: (DISSOLVED OXYGEN) 70% increase in DO measured at the lagoon discharge point with ESP injection, against the baseline period. Surface aerators continually on. Concurrent with 39% increase in TCOD loading.
