Control of Bacteria for Industrial Fluids and Processes

Effectiveness of NanoCleanse System

Control Bacteria without the use of Toxic Biocides

LCP Tech Inc. has developed a mixture of non-toxic enzymes called NanoCleanse®-SRB. This chemistry stops odor and corrosion by preventing hydrogen sulfide (H2S) gas from being created by the presence of Sulfate Reducing Bacteria (SRB). The use of NanoCleanse-SRB disrupts the capability of sulfate reducing bacteria (SRBs) to form and fortify the slime layers, which is the major source of H2S.

Sitters vs Swimmers - In most systems or processes, there are bacteria that reside in the slime layers or biofilms -we call these the "sitters". There are also the "swimmers" which are found in the process fluid. Most biocides are ineffective in controlling bacteria because the sitters hide in the biofilms and wait for the biocides to pass. The swimmers are killed and typical test strips indicate lower level bacteria counts. The sitters then reproduce and the bacteria counts come back. More and more biocides are needed as the "sitters" grow. With the NanoCleanse system, the chemistry prevents the ability of SRB bacteria to form and fortify the slime layers which eliminates the "sitters" while the equipment eliminates the "swimmers". This results in process fluid that is always clean.

LCP Tech’s proprietary enzyme  formulation, NanoCleanse®-SRB, controls hydrogen sulfide (H2S) gas created by the presence of Sulfate Reducing Bacteria (SRB). SRB convert sulfate in water to sulfide, resulting in a number of adverse effects, which includes:

1. Generation of toxic hydrogen sulfide, “rotten egg smell”

2. Severe pitting and corrosion [(MIC) Microbial Induced Corrosion], even in stainless steels and concrete

3. Metal precipitation, which enhances biologically generated sulfide

4. Forms biofilms (slime layers)  which resist even the strongest biocides

5. Presence of SRB also contribute to fungal growth

 Benefits of using NanoCleanse®-SRB

1. Non-Toxic, Worker Friendly Product

2. Stops generation of hydrogen sulfide gas at the source and eliminates odor of “rotten eggs”

3. Controls microbial induced corrosion (MIC) by stopping H2S.

4. Eliminates black sulfide precipitates.

5. Stabilizes the pH

6. Extends sewer or bath life

7. Slime layers naturally sloughs off wherein the sulfide is generated

8. Controls fungal growth caused by presence of sulfide

LCP Tech, Inc. has also developed proprietary equipment that controls all bacteria and fungus. This NanoCleanse equipment does not use traditional biocides that typically are used in controlling bacteria in industrial fluids. The NanoCleanse® equipment works in conjunction with the NanoCleanse®-SRB chemistry.

In Case Study 2, the process at the automotive manufacturer was enhanced by using the NanoCleanse System which added further cleaning quality and cost benefit. The "NanoCleanse Sterilization Equipment" combines the enzyme chemistry with destruction of the swimmer bacteria which resulted in cleaner parts and fewer bag changes. Bag changes were reduced from 3-4 times/ day to 1-2 times/day. This reduced the labor required to change the bags as well as an additional $240/day or $86,000/year for the actual bags. The real benefit comes from the quality of cleaning.
