Filamentous Identification New training program

Two of the largest costs at a typical wastewater treatment plant are electricity and solids handling. Reducing some of the solids at a municipal plant can be achieved in some cases. If your plant has filamentous bacteria problems- reducing the amount of filaments can decrease the amount of sludge created, cut polymer costs and sometimes reduce hauling costs. How do you know if you just have too high a MLSS vs. filamentous bulking?
O ne thing that can be done is to run a settleometer testRun a normal settleometer with the MLSS- Run a second one along side with 50/50 diluted with normal tap water. If the second one does not cut the rate of settling by half during the 30 minute settling time period, chances are that you have filamentous bulking. Next, look under the microscope to see if there is bulking or bridging. Make sure you use a higher power. Many times filaments are overlooked- internal bulking is just as bad as bridging if not worse! See our additional training sections on Filaments- knowing the causes of the filaments will help you determine what type of proper process controls to change. Ask for training on Solids Handling and cost reductions. Ask for additional information on a Sludge Reduction Program. Do you have problems with Grease in your lift stations that is causing filaments downstream?
Lift station Prior to use of Bacterial After use of biological products enzyme products for grease removal Grease removal by using bacterial products can not only clean out your lift stations and reduce costly maintenance problems, but it also helps reduce jetting out the lines, and additional grease loading and filamentous problems with Nocardia and MicroThrix at your wastewater treatment plant. Clarifier optimization can impact the RAS and solids that not only are returned to the front of the plant, but what condition the sludge is in that is sent on to dewatering. Ask about our Clarifier Optimization training. Nitrification can be a big problem. An overall nitrogen balance is recommended. Just because the EPA does not make certain tests required, does not mean that they should be performed for process control and optimization. Learn more . . . .. . Oh no, my nitrifiers are dead and I am not getting nitrification! Why you should do a Total Nitrogen Balance Amines in my Influent- Municipal Plants Are you having foaming at your plant? For more information on additional ways to decrease grease What is growing in your collection system Not all plants have Nocardia- Some have Microthrix- Some just have too many solids and low DO? Some have zoogleal bulking- Ask for our training information sheet on Foam-
Foaming at a plant with Microthrix vs. Zoogleal bulking Are you having problems with Grease? or low nutrients and high loading due to industry? Information on these, training programs and audits are available from Environmental Leverage. Our goal is to help bring new solutions to you! Whether that means products, new programs, training, consulting, audits or lab work. Why you should do a Total Nitrogen Balance

Case History : Municipal Foaming and Nocardia
We started working with a municipality that had a history of foaming problems and Nocardia for years. They already were on a biological program. We came in, audited the plant, made some process recommendations, changed the program to a dual program. You can see solids build-up in the clarifier and the scum box is filled. The photo on the right is the thick Nocardia foam in the aeration basins. For the first time the plant has actually seen MLSS in the aeration basins!
You can see the surface of the aeration basin, normal mlss and the scum box now only has a small amount of scum. This plant will have to fight grease and foaming continually until it has an upgrade to the system, since it does not have prescreening to remove some of the grease and solids that do come in to normal municipal systems. Optimization of the primary, changes to the solids handling in the clarifier and a minor adjustment to the bacterial program will help to keep the plant running more smoothly though in the meantime!
