Description

BELCAN is an effective biocide for controlling algae and slime growths. It is a liquid, non volatile, water soluble compound with the added advantage of being non- toxic. It has a high degree of bactericidal and bacteriostatic activity, and is effective against  a wide variety of bacteria, fungi, seaweed and algae. It is a mixture of quaternary ammonium chloride compounds and other biocidal  agents  in a stable buffered solution for use in recirculating cooling tower water systems, air washers and evaporative condensers.

BELCAN may be used in any system without the need for costly, special feeding equipment.

Advantages of BELCAN

Since BELCAN is non-volatile, its concentration in a cooling system is independent of the circulation rate. The concentration is decreased by bleed-off, by reaction with growths, and by absorption upon the interior surfaces of the system. Effective treatment requires attaining a relatively high concentration in the system for a short length of time, rather than maintaining a small residual continuously.

When initiating the use of BELCAN in any system, it is essential that a higher treatment rate be followed for a period of 4 to 6 weeks. This schedule will serve not only to remove heavy infestations of slime and algae growths, but will also make it possible to saturate the surfaces of the system with BELCAN.

Dosage

BELCAN should be normally applied in a concentration of 20 – 40 PPM once a week.

The above dosage can be increased or decreased depending on the temperature, on visual inspections, microbiological analysis and / or experienced observations of a water treatment representative.

Disadvantages of ordinary algicides

Many of the chemicals which are being used for algae control exhibit an initial period of apparent effectiveness, followed by renewed growth of the organisms. Due to mutation of the organism, such renewed growth indicates the development of resistant microbiological strains. These slime and algae deposits will promote corrosion since they liberate oxygen. Even some of the ordinary treating chemicals, such as chlorine, are themselves corrosive, frequently attacking the wooden surfaces of the cooling tower, causing delignification. Many are also toxic and irritating, such as organometallic compounds, requiring special handling precautions.

Compatible with most water treatment products, except anionic surfactants.

Eurochem Biocide program

In order to avoid mutation of organisms which make them resistant to biocides the process we recommend is a four-week cycle as follows:

Use BELCAN for three weeks and for the fourth week use our product BIO-3290.

The organisms that have become habituated to BELCAN are immediately destroyed by BIO-3290.

Repeat the procedure from the beginning.  Use BELCAN for three weeks and BIO-3290 for the fourth week.

You can feed BIO-3290 with a metering pump at any point where uniform mixing can be attained. Use corrosion resistant equipment.

BIO-3290 can be added continuously or periodically, with adjustments in the intervals between additions and dose levels dependent on visual inspections, microbiological analyses, and/or experienced observations of a water treatment representative.

• Treatment levels

For closed systems a normal feeding of a 25 ppm shock once to twice a month is normally sufficient.

For cooling towers and air washers shock of 25 ppm twice a week is recommended.

For the control of bacterial, fungal, and yeast growth in pulp, paper, and paperboard mills, add

BIO-3290 at the rates of 50 to 150 gr / tn of dry paper.

• To remove slime from fouled systems.
• Add 500 ppm of BIO-3290 2-3 times a week until the system is clean.

Description

BIO-CLOR is a powder, biocide and cleaner, feed, stabilized chlorine biocide, activated by small quantities of bromine in order to give chlorine more power.

With this procedure common chlorine becomes an extremely strong disinfectant, fungicide, algaecide and/or slimicide for wastewater, commercial and industrial waters, cooling towers and closed recirculating systems, without any harmful environmental side effects.

BIO-CLOR is also used to control biofilm deposits in pumps, pipes, heat exchangers and filters associated with industrial water treatment systems.

This powerful broad-spectrum biocide effectively and quickly controls bacteria, algae and fungi.

Usage

• To remove slime from fouled systems:

Add BIO-CLOR to provide a level of residual chlorine of at least 2 ppm. Circulate for 2 – 3 days keeping the residual chlorine at least 2 ppm.

• For maintenance:

Add BIO-CLOR to provide a level of residual chlorine of 0,4 – 0,7 ppm.

Description

Usage

BDS 6500 microbiocide is a broad spectrum, antimicrobial product designed specifically to control slime forming bacteria, sulphate reducing bacteria and algae in industrial recirculating cooling water systems.

BDS 6500 can be used over a wide pH and temperature range and releases no odor or foam at the indicated levels.

As for the active ingredient, BDS 6500 is a concentrated solution of Glutaraldehyde.

Technology

Glutaraldehyde

Chemically, the cell walls of bacteria contain a unique protein, which, specifically, is a combination of different amino acids. The amino groups are typical organic bases and effective nucleophilic compounds.

Glutaraldehyde reacts with the proteins of the bacterial cell wall and the proteins within the internal portions of the cell via a nucleophilic substitution reaction. The reaction will be internal or external depending upon the pH of the water.

Activity

BDS 6500 shows particular strength in controlling sulfate reducing bacteria. Published literature specifically points out the combination of glutaraldehyde and isothiazolone as being very effective in the control of this troublesome bacteria.

BDS 6500 is also unaffected by oil contamination, making it a popular toxicant in refinery and oil production applications.

In reviewing the mode of microbiocidal action of BDS 6500, it is evident that it shows efficacy over a wide pH range. The ability of this material to work more rapidly at high pH makes it a popular choice in alkaline cooling water systems.

Feeding

The quantity of BDS 6500 required for any give application will depend on such factors as the type and volume of the system, the extent of microbiological contamination and the degree of control required.

BDS 6500 may be directly fed from the drum or diluted with water and fed by any suitable chemical feed system.

BDS 6500 should be dosed directly into the sump or basin or any location where good distribution can be assured.

Description

BIOBROM-Q is a liquid, single feed, stabilized bromine biocide, used in combination with chlorination in order to give chlorine the power of chlorobromination.

With this procedure common chlorine becomes an extremely strong disinfectant, fungicide, algaecide and/or slimicide for wastewater, commercial and industrial recirculating cooling water systems and industrial once-through cooling water systems, without any harmful environmental side effects.

BIOBROM-Q is also used to control biofilm deposits in pumps, pipes, heat exchangers and filters associated with industrial water treatment systems.

Features

This powerful broad spectrum biocide effectively and quickly controls bacteria, algae and fungi through NaOBr action.

NaOBr is a powerful broad spectrum biocide recommended for disinfection of recirculating and once through cooling systems, food processing equipment (pasteurizers, sterilizers or retorts), air washers, and other industrial water systems.

BIOBROM-Q is recommended for alkaline (7,5 < pH < 9,5) and contaminated waters (NH3 and nitrogen), where chlorine is not giving efficient microbial control.

NaOBr remains active in alkaline waters (pH=7,5-9,5) resulting in more efficient disinfections than when using chlorine based biocides.

BIOBROM-Q suffers less from flash-off losses (compared to chlorine based biocides).

BIOBROM-Q offers all of the advantages of bromine chemistry combined with the ease of dosing:  there is no need for labor intensive and complex feed equipment, simple dosing pumps are sufficient.

Feeding

The product dosage rate will depend on the system design, water characteristics and operational parameters. In most of the application a residual 0.2-0.5 ppm of residual free available halogen is sufficient to keep control of the system. As a chlorination supplement BIOBROM-Q should be dosed at 0,05 – 01 ppm.
