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.

We have developed a full set of Basic training, Advanced training, Filamentous Identification the Easy Way as well as custom training CD's Manuals. We also provide hands-on training classes and soon will have an Online "E-University".


Audits and Consulting:

At Environmental Leverage® Inc., we have a team of experienced individuals who come into your plant with a fresh pair of eyes.  The system is checked from influent to effluent.  System optimization, equipment efficiency and operational excellence are key components explored. Key Benefits Equipment efficiency Total Cost of Operation reductions Reliability and safety

An onsite audit is conducted to examine system parameters, process controls, and current monitor and control procedures. A physical walk-through is conducted, process flow diagrams are examined, previous design criteria are examined and current standard operating procedures are evaluated along with data logs.





What's New!

We have just added "Virtual Audits" to our capabilities. Check out our new Services.  We are in the process of developing an ""Online E-University" in order to meet the needs of our global customers that cannot travel to our public classes. Stay tuned for details and updates.

steel mill

Typical Steel Mills use acids in the pickling process.  There are a ton of companies now that can help them reuse and regenerate the spent acid. After final use though, depending upon the concentration of metals present, this acid may also be used for pH adjustment at other waste treatment plants.  Oily sludge is generated and usually sent off to waste haulers at significant costs. There are alternatives to this also depending upon the plant, the types of cokers, blast furnaces, EOF's or BOF's, and metals present.


Steel is one of nine energy- and waste- intensive industries that is participating with the U.S. Department of Energy's Office of Industrial Technologies in a new collaborative R&D strategy called "Industries of the Future."


The steel industry (including iron production) is one of the largest energy consumers in the manufacturing sector and has invested more than $7 billion in environmental controls.

Steel is the most recyclable and recycled material in North America, with an overall recycling rate of 68 percent.


Scrap and other materials are recycled extensively in the iron and steel industry to reduce the raw materials required and the associated pollutants.
Some of these recycling activities include:
• Recycle or reuse oils and greases.
• Recover acids by removing dissolved iron salts from spent acids.
• Use thermal decomposition for acid recovery from spent pickle liquor.
• Use a bipolar membrane/electrodialytic process to separate acid from metalsteel mill by-products in spent NO3-HF pickle liquor.
• Recover sulfuric acid using low temperature separation of acid and metal


Water usage at a steel mill can be high.

Come take a walk through various Steel Mill Wastewater Plants.

You can see inside the collection systems as well as walk through their wastewater treatment plants.

They can be very old facilities, or have the latest, state of the art technology on the process side as well as the wastewater side.


There are tons of files containing information on every subject from A to Z on the internet with standards, benchmarks and industry BMP's.  The problems is, who has time to dig and find it all. It is not always in easy to find places.  We have tried to show you some of the ones we though might be useful. There are links to the places where we found some of them in case you want to dig deeper on a particular subject and find out more.


Key Inputs and Outputs

Key inputs include boiler feedwater, condensate returned, water treatment chemicals and air/oxygen input. Key outputs include steam mass flowrate, steam pressure, steam quality, combustion gas conditions.


The Average Solids Generation Ratio To Use As Benchmark in a wastewater treatment plant for sludge:
Basic Steel (coke): BOD 1.0:0.15 Sludge


MicroSolv 410 can be used to help biological problems at a steel mill.
Bioaugmentation in Steel mills for BOD and TSS reduction


Areas in a wastewater treatment plant that can be optimized:
API or DAF,  Holding tank or scum pit that collects oil and scum

With all the Green Grants and interest in alternative fuel sources, recovery and reuse of spent oils has grown
Oily emulsion spill can lead to a violation   

Algae on weirs can lead to TSS violations in final effluent

Scalping tank can be optimized

Solids build-up on scrapers of DAF

Sludge Thickener       

Clarifier with too many solids and gassing

Oil slicks near clarifier burping up can lead to permit violations

Oil can be sold to waste haulers to be re-used as fuel instead of being charged disposal fees

Case History-Tank Remediation at a PetroChemical Plant

petrochemical plant tank remediationWe are working with a PetroChemical plant down in Louisiana. They had an 800,000 gallon tank filled with wastewater that they wanted to clean up and empty out. We suggested a biological program-MicroSolv 400 for tank remediation.
The plant started the program and had the tank cleaned up in less than three weeks, yet the tank had been sitting there filled for over three years. They were tremendously impressed. They would have spent hundreds of thousands of dollars to haul out the waste.
Tank remediation is not really that hard. As long as the contents are organic, it is actually quite simple. To the bacteria, it is just food. Since the waste stream is already isolated, it becomes just a time and numbers game with the right species of bacteria. Inoculate the tank with bacteria, make sure the critical 5 are in place- (pH, D.O., temperature, N and P) and watch them go to work!


It does not really take long depending upon how much you seed the tank with. And the bacteria grow and multiply exponentially, so just sit back and wait. You wind up with a clean tank, clear effluent, and some bacteria residuals on the bottom of the tank that need to be disposed of- ( usually sent to the plants onsite dewatering system) or land applied.

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~

Audits and Onsite Training and Consulting

 In order to "Audit" or Troubleshoot a Steel Mill  wastewater treatment plant, a number of things need to be looked at. A physical walk-through of the plant needs to be conducted with visual observations noted. A microscopic analyses of the Biological portion of the waste treatment system needs to be conducted. Settleometer Testing needs to be conducted A sludge judge should be used on a Clarifier Examination of lab data- current testing procedures and results Walk through and correlation of process side to wastewater treatment plant operations A fully detailed final report is issued with process recommendations, system changes, areas for optimization and increased efficiency.
