DONIPHAN, MO
BASE LINE DATA- May 23, 2018
COD: 92 pH: 8.20 DO: 6.26 Average Sludge Depth: 15.5 feet
CURRENT DATA – July 29, 2019
COD: 49 pH: 6.31 DO: 2.2A verage Sludge Depth: 13.5 feet
- Their DO, and pH, are low because of the excessive duckweed. Duckweed is a DO killer, blocking the oxygen-transferring interface between the surface of the lagoon and the atmosphere. And because duckweed inhibits algal growth, the lagoon doesn’t receive any of the natural oxygenation that algae provide. We recommended that they try and kill the duckweed as soon as possible. COD, on the other hand, was lowered due to our chemistry.
- The sludge judge we performed on July 27th, 2018 showed an average of 15.5' of sludge. On July 29th, 2019 the average was 13.5'. Our chemistry lowered the sludge blanket by 2'. In the northeast corner of their primary lagoon, we measured 0" in 2 points.
HENNESSEY, OK
BASE LINE DATA- October 17,2018
COD: 538 pH: 7.64 DO: 4.64 Average Sludge Depth: 5 feet
CURRENT DATA - October 6, 2019
COD: 190 pH: 7.88 DO: 7.81 Average Sludge Depth: 0.8 feet
- Their pH is staying steady, DO has risen and COD dropped dramatically. All of these positive improvements are because of the reduction of their sludge.
- Our chemistry lowered their average sludge blanket to under a foot. The highest reading we recorded this year was 1.5 feet which was in the middle and the northeast corner. Those same two readings a year ago was 6 feet in the middle and 5 feet in northeast corner. loyal ones.
CHELSEA, OK
BASE LINE DATA- March 11, 2019
COD: 572 pH: 9.15 DO: 5.1 Average Sludge Depth: 3.3 feet
CURRENT DATA – March 11, 2020
COD: 119 pH: 7.25 DO: 7.79 Average Sludge Depth: 2.3 foot
- Their COD has drastically reduced in a year, DO has risen and pH has neutralized. We would’ve seen more reduction in their sludge blanket if they weren’t having to battle with the duckweed this past summer. We now have a resource that can eradicate it if it does come back. Odor was non-detectable and wildlife in/around the lagoons was vibrant.
- Our chemistry lowered their average sludge blanket by 1 foot. March 11, 2019 showed an average of 3.3 feet of sludge. On March 11, 2020 the average was 2.3 feet. The highest reading we recorded this year was 3.5 feet which was in the west corner. The same reading a year ago was 7 feet.
FARGO, OK
BASE LINE DATA- April 4, 2019
COD: 2626 pH: 8.82 DO: 9 Average Sludge Depth: 3 feet
CURRENT DATA – May 1, 2020
COD: 234 pH: 9.08 DO: 21.89 Average Sludge Depth: 1 foot
- pH is on the high range when algal growth is maximizing, this is due to the release of oxygen and hydroxide alkalinity when the algae consumes CO2 during photosynthesis. Every now and then pH can skyrocket when algal activity seems minimal. DO has doubled and COD dropped by 91%. All of these positive improvements are because of the reduction of their sludge. On our first sludge judge, sludge was extremely thick and hard to release out of tube. This year, sludge was more slurry and released out of tube with ease. No odor present. Nice emerald green color to lagoon.
- Our chemistry lowered their average sludge blanket by 2 feet. The highest reading we recorded this year was 2 feet which was in the south corner. The same reading a year ago was 5 feet in the same south corner.
