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 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.
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.
Cooling towers can be a critical process in many industrial production
can also destroy cooling towers if they are made of lumber. Corrosion can
occur on metal parts.
What are the typical Biological species found that could cause corrosion and Biofouling?
Aerobic and anaerobic bacteria
MIC bacteria (sulfate-reducing, acid producing, nitrate reducing,
Iron/manganese depositing bacteria
Thiobacillus spp., Gallionella spp., Sphaerotilus spp.
Yeast and Fungi
presence of large amounts of yeast or fungi can indicate a low pH, or
existence of fermentative conditions. There are more than 75,000 species of
yeast and fungi, which include mold, smut, rust and mildew. They may be
colorless or cover the entire color spectrum. Most grow best in warm, dark,
moist places. Most are aerobic with low oxygen demand. A few, including
yeast, are anaerobic. Fungi can grow on almost any surface and are
considered an attributing factor to wood deterioration. Both yeast and fungi
are commonly transported by air currents. They are relatively large and can
easily be identified with microscopic analyses.
Two forms of fungi commonly encountered are molds (filamentous forms) and
yeast (unicellular forms). Molds can be quite troublesome, causing white rot
or brown rot of the cooling tower wood, depending on whether they are
cellulolytic (attack cellulose) or lignin degrading. Yeast are also
cellulolytic. They can produce slime in abundant amounts and preferentially
colonize wood surfaces.
Identification: Yeast are a
group of unicellular fungi a few species of which are commonly used to
leaven bread and ferment alcoholic beverages. Most yeast belong to the
Yeast can be similar to Tetrads
Yeast can be similar to Tetrads
primarily occur in the tower deck area because most species require sunlight
for photosynthesis and growth.
What type of Algae are you growing in your cooling tower?Algae can be branched or Straight
Algae can be curled or in small free floating clusters with a slime coating
Anabaena Woronichinia naegeliana
Achnantes taeniata is a brown algae Filamentous Blue Green algae or cyanobacteria and Beggiatoa
Aphanizomenon flos-aquae Scenedesmus and Flagellate
Branched algae Algae growing on cement and metal railings
Diatoms are algae enclosed by a silicaceous cell wall and may also be present in cooling towers but generally do not play a significant role in cooling system problems.
Microbiological Influenced Corrosion or MIC
MIC is corrosion or deterioration of material, which is initiated and/or accelerated by the activities of micro-organisms. These materials are mainly metal, but also can be concrete or plastics. 1/5 of all corrosion is typically caused by microorganisms and biofouling. The most common MICs can be categorized into sulphate reducing bacteria (SRB), iron oxidizing bacteria and acid producing bacteria (APB).
Sulfate Reducing Bacteria
can include Desulfovibrio, Purple sulfur bacteria, Beggiatoa, Thiobacillus, Spaeratolis Natans SRBs are characterized by hydrogen sulfide odor and blackened water or black colored deposits. Iron oxidizing bacteria generally form in filamentous clumps and can be detected under microscope by their distinct appearance due the excreted products that grow. This corrosion by iron bacteria often forms tubercles.
Beggiatoa is a motile sulfur reducing filamentous Bacteria found in many biofilms
Purple sulfur bacteria Spirillum and S natans
S. natans Filaments with sulfur granules
Iron Depositing Bacteria
Iron depositing bacteria grow best in low oxygen environments but are common in open-circulation systems. Gallionella and Sphaerotilus use soluble, or ferrous, iron as an energy source, and convert it to an insoluble oxide or hydroxide form. These deposits create fouling and set up concentration corrosion cells and conditions under which anaerobic bacteria flourish. Gallionella frequently leave spiderweb-like deposits on metal surfaces. The deposit looks like black iron. Severe corrosion is usually evident under the deposit.
Other bacteria that may be present in cooling water include Pseudomonas, Klebsiella, Eneterobacter, Acinetobacter, Bacillus, Aeromonas, and Legionella Spore forming bacteria Denitrifying bacteria, or pseudomonas, can cause the loss of nitrite inhibitor in closed-water systems. Usually plate counts with differential media are used to determine the exact count of these types of bacteria
Biofouling Slime or Slime forming Bacteria
As you can see, there are quite a few different things that can be determined under the microscope from Cooling tower water samples.
Many things can be determined that can save time, money and reduce multiple traditional tests.
Call our lab to find out how to schedule a microscopic analyses of your cooling tower water or slime that has built up.
