Lab Services:

Filamentous Identification Lab Service. One reason to identify filaments is to determine the filaments characteristics and then determine the type present.  If the type is found out, a root cause can usually be associated with a particular filament.  If the cause is known, then a correction can be made to alleviate problems. Chlorination is only a quick fix.  Without process changes, filaments will grow back after chlorination.

Wastewater Biomass Analyses and Cooling Tower Analyses also available

 

Training Materials:

Training is an integral part of any job. Not everyone is at the same level of training. Many people want beginning concepts and basics. Some need technical information or troubleshooting. Some want equipment, technology or process information.

Operators of sewerage systems know that grease and FOG in lift stations is a major problem. The grease obstructs floats and reduces the life of pumps leading to SSO's and a need for frequent service. Obstruction by grease is the most prevalent cause of force main backups and sewage overflows, costing the industry billions of dollars annually. The majority of sewer line blockages are caused by grease build-up as opposed to debris.

 

Recalcitrant long chain fatty acids make up approximately 80% of grease deposits found in lines and grease traps and require extensive physical cleaning to avoid blockages, odors, and the passage of grease in effluents to be re-deposited downstream. Bioaugmentation has been used to break down difficult to degrade substances preventing them from causing blockages, odors, or accumulations downstream. In field tests on grease traps and lift stations this technology has grease removaldemonstrated a visible difference in the elimination of grease build-ups in trial periods shorter than one month.

        

MicroBlock and MicroClear 207

Biological treatment with Environmental Leverage is a simple, efficient and cost effective remedy against grease in collection systems and wastewater treatment plants. These products contain a specially formulated range of adapted high-performance microorganisms developed for use in the biological wastewater treatment of greases, fats and oils (FOG). As well as microorganisms, our products contain surface tension depressants and penetrants, which loosen and liquefy heavy grease deposits, thereby assisting in their biodegradation. For Grease and Sewer control, the powdered products and solid bio block products, also contain specialty penetrants and surfactants, which loosen and liquefy heavy grease deposits, thereby assisting in their biodegradation

Compare this treatment approach to traditional cleaning/pumping/hauling costs of thousands of dollars or in-ground repair costs of tens of thousands! And there is no guarantee that the same grease-related headaches won’t crop up again and again at the very same location after traditional maintenance. Traditional “remedies” don’t solve the problem but act more like a Band-Aid, because the same contributors to the system will keep pouring the same grease down their drains & disposals, perpetuating the same scenario over and over again. Bioaugmentation is a proven and PROACTIVE approach to naturally degrade these clogging wastes at their biological source, and prevent future buildups/failures.

I need to get rid of the grease and FOG in my lift station. I heard about using bacterial products. How do I know if they are working?

Lift stations commonly end up with build-ups of grease that can create a ring around the lift station, collection build-up on pumps, chains, floats, sidewalls, etc. This can cause mechanical problems, cause plugging, interrupt service and cause terrible odors. Operators know what that means: jetting the lines, pumping & hauling off the grease at high costs, or even digging up and replacing a wet well and/or feeder lines at extremely high capital costs.

 

heavy grease in lift stationFats, oils and grease (FOG) are typically the cause of many problems. Grease is "hydrophobic," which means it prefers to cling to surfaces that are free of water. Large amounts of oil and grease in the wastewater that goes down a drain can cause sewer lines to clog sewer lift station failures, wastewater treatment plant problems and environmental concerns. Grease typically will build from the top down or around the sidewalls and at the water level in the sewer line while heavier debris may collect on the bottom as the wastewater flows through the sewer line. Grease can continue to build up and restrict the flow of wastewater. Sometimes, a layer may break off and large pieces can create plugging downstream. Eventually, grease will form a total blockage in the sewer line if left untreated.

 

Grease is one waste that the sewer system cannot handle and therefore needs to be kept out of the system, but most often is not. An additional concern is that since the government raised the temperature required by restaurants and food establishments from 180 F to ~210 F, grease traps are not working as designed and grease that used to be trapped onsite is now washing through the lines until the temperature of the water cools down and then hardening later on. This usually happens somewhere in the lines or in the lift station.

 

Our biological additives are a safe, natural environmental friendly way to help assist in the cleaning up of a lift station, but they are not miraclegrease in manhole workers. There is a limit to what they can do, how they do it and when they will work. Bacteria can naturally degrade the fats, oils and grease, as well as any other organic materials that enter a lift station of pipe. They actually consume these as a food source, as opposed to traditional methods of surfactants, enzymes or chemicals that may have eliminated the grease in the lift station, but just transferred them down the pipe and eventually into the wastewater treatment plant and can cause upset conditions. Biological products cannot in a realistic time degrade some of the solids such as plastics, condoms, etc. that wind up in the lift station. Some of these eventually build up and must be mechanically removed.

 

Bacteria not only clean the lift stations if properly applied, they can help clean up the lines and can lighten the load at the treatment plant and reduce solids or help with BOD and TSS loading. Again, it is all in the program addition, conditions such as flow, temperature and loading that impact whether a program will impact just the lift station, the pipes or the treatment plant. The correct dosing and application will lift stationimpact different variables and determine the impact on all three places. In the past, bacterial vendors or sanitary workers worried only about the lift station. Cleaning up the grease and quickly was the only concern. High levels of bacteria were added to the lift station. This may have cleaned up the lift station, but it just moved the grease down the pipes, clogged up the lines and caused high foaming at the treatment plant. Newer more conservative methods are now used to successfully dose a biological program in a lift station. Slower is better, although many people are anxious and say the product is not working.

 

What are signs that the product is working-

 Foaming in the lift station- white foam at first shows the bugs are in a high growth phase, as the foam turns to a light brown, they are getting a little older. 
Are there signs of the grease softening?  grease in lift station
Are there visible signs of cracks in what was once a solid surface?
 
Make sure the biological product is in the water and not just sitting on top of the grease shelf. The product cannot jump out of the water-soluble bag. It needs some access to the water in order to move around, below and above the grease.  Try adjusting the water levels in the lift station and move the float a bit higher.
 
grease ledgeIf there is a grease ledge, this is very important, since the water level must be a bit higher for a short period of time to allow the bacteria access to this grease and not just during high flows.
 
Spaces between the grease, white coloring of the water, some softening and foaming show the product is starting to work.
 
More free space in the lift station, cleaner lines and floats show the product is doing a good job and on the way to a cleaner lift station.

 

These have been called "Floating Turtles"- Hard solid formations that float around in the lift station. These can interfere with the pumps andgrease turtles can clog the pipes.  Sometimes using a liquid product to spray on these can help reduce their size and shrink them faster.
 
Raising or lowering the float will not impact situations with turtles.
