Dear Mr. Erickson:

Please find below the results of analyses we performed on the two wastewater samples we received on April 4. These were samples of wastewater lagoon and were identified as (1) lagoon sample and (2) lagoon pump. These samples were analyzed in order to assure ourselves that appropriate concentrations of nutrients were present for the growth of large numbers of micro-organisms and to be certain that inhibitory quantities of toxic materials were not present.

Following this initial analysis, an aliquot of each sample was inoculated with Aqua Clean at concentrations of 5 parts per million (PPM) and at 10 PPM. These samples were then monitored over a seven-day period through April 16th. The following is a summary of the results of the 5 PPM concentration which resulted in the best overall performance.

All data are in mg/l

As you can see, a very good reduction of COD and suspended solids concentration has been demonstrated over the test period for the inoculation level. The reduction of COD over the seven days ranged from 69 to 98 percent, depending upon sample type and dose rates of AquaClean. The suspended solids reduction ranged from 72 to 97 percent because of the same variable. By observing the increased reductions between the untreated and the treated samples you see clearly the benefits possible by using this material. The COD reductions were 17% and 64% greater in the treated sample at 5 PPM. We feel quite confident that the addition of AquaClean to your wastewater treatment system will affect similar removal rates of these parameters. Initially there was a trace amount of hydrogen sulfide (1.24 mg/l) present in the Lagoon Pump sample but this was below detectable limits after the third day.

In view of the reduction rates achieved over the test period, we recommend the application of 30 gallons of AquaClean for the one time seeding of the lagoon. After this initial dose, a maintenance dosage addition of 1 gallon every week should be continued in order to assure appropriate waste treatment, and maintain proper populations of AquaClean organisms. In cold weather operation this could be dropped to 1 gallon every other week.

With adherence to the above recommendations we can assure you of the same reductions as our tests have produced, further, no odors due to H2S would occur. After the initial application of AquaClean your system will operate with improved efficiencies and cost effectiveness for years. Laboratory analysis to monitor the progress of the treatment is imperative at least for the first month and should include COD, suspended solids, BOD, and respiration rate.

So, if we can be of any further service to you please feel free to call at any time.

Sincerely,

William P. Pfeiffer, Ch.D
