Papermills: Case History with Total System Optimization: 100% Recycle papermill with a once through lagoon The first stage of the lagoon was aerated, second and third settling lagoons. Large amounts of algae, scum and duckweed covered the last two stages of the pond. This pond was on a bioaugmentation program for years.
An audit was conducted, recommendations to move one of the aerators to the first half of the second stage were made to allow more oxygen to carry through the rest of the system. Bioaugmentation was changed from 2-5 lbs of product per day from local supplier to 1-2 lbs of MicroSolv 118 and 1 lb of Micronutrients M100. In less than 2 weeks, the scum was gone off the pond, the BOD and TSS removal improved, floc structures increased significantly and higher life activity went sky high. Short, free floating filaments dissappeared. Spirillum ( usually an indication of septic conditions) and zooglea were gone after changes in treatment. Some filaments are still in the floc structures, mostly Type 021N, but that is due to solids handling problems in the primary clarifier that are under consideration for optimization.

The plant at one point had an upset for a two week period, twice the loading of BOD was entering the lagoons. The final BOD was still below previous years final effluent values and way below permit levels!
Here is an update on the Papermill Case history. We were asked over a year ago to come in and troubleshoot for a papermill with a once through lagoon. We made some process recommendation, gave some training and revised their current bioaugmentation program. The final effluent had the best BOD in the history of the plant while they were on our program. But, since the plant was on a "sole source " agreement with a major supplier of all their chemicals, they were forced to go back to their original supplier for biological products. Well, after just 6 months, the plant is back on our products and program. The results could not even come close on their program! While we believe some of our products are specially formulated and are very good, the major thing we believe is important is the training, consulting, analyses and support that we have to offer. But the real proof is in the final BOD number! Check to see how we compare. . . . BOD final permit limits are 25 and TSS numbers are 30 ppm. We consistently hit close to 5 ppm BOD once the program was up and running! Very good for a papermill! Even the cold weather months with a normal slowdown in activity, the BOD was still on the mark! The TSS variable was not something that could really be correlated between trians, since it is more a function of the primaries. During both trials, they just installed a number of new thickeners, and a new sludge recycle pump during various points in this trial. While TSS can be a driving issue and impact loading on the plant, it was harder to correlate between both companies, you could say the loading was higher in the trial, but BOD was the real clincher More data on this case history!
Soil Remediation- Case History Industrial zone Alon Tavor Israel Plant Issues 900 m3 of Contaminated Soil. Pollution: Crude oil. Several option where evaluated and E. H. Green/Environmental Leverage bioaugmentation program solution was elected. Due to the Hydrologic Area which the plant is located in ,the EPA of Israel instructed the plant to move the soil or reduce the TPH ( Total petroleum Hydrocarbons) from 842 to 100 ppm. Initial proposal assumed that it would take a few months due to high heat in the summer, and mainly the amount of soil and contamination to treat. After two weeks, TPH was down to 311, the following week, 133. Final TPH levels were pulled at 4 locations- 38, 39,81 and 37 were the final TPH readings, ~90-95.6% reduction in TPH ( Total petroleum Hydrocarbons) 80% cost reduction in treating the soil biologically including labor, nutrients, biological products, etc vs. hauling out the dirt as hazardous waste~ Soil Remediation Case History- Total Petroleum Hydrocarbons

The primary clarifier still needs a bit of solids handling optimization, but
the plant is waiting on an additional tank upfront to store settled solids that
are recycled back into the system. There were too much floating solids on
the surface, which always indicates holding solids too long in a clarifier. The
Beds need to be lowered. The plant was getting a new WAS pump to recycle some of
the primary solids back to the front of the system. When the system was finally
optimized, they were able to achieve 98% TSS removal in the clarifier!
