POLYCIDE is an unique formulation based on conjugated phenolic compound :- Dichlorophene (5.5 dichloro, 2.2 dihydroxy, diphenylmethane) as an active ingredient. It is recommended for the control of slime, and algae in all types of water systems and humid atmospheres. Its dispersion property helps in the excellent distribution of active content in the slimy masses and water systems. It is effective over a wide range of pH higher than 7.5 when other biocides lose their activity. POLYCIDE is an exceptionally broad-spectrum biocide with powerful bactericidal, fungicidal, and algicidal activity. It is active against organisms found in vegetative growth in water-cooling systems and other places. The organisms consist of algae such as yellow, green, bullish green, and brown; the fungi such as Aspergillus niger, Ascomycetes, Basidiomycetes, and Bacteria such as S. Typhae, S-aureus, etc. It acts against the Cell Wall and protoplasm of the organism and arrests the bioactivity. POLYCIDE contains ingredients, which are stable and effective in the presence of extraneous organic matter. The concentration of fewer than 60 parts per million (ppm) controls many of the organisms normally found in industrial waters.
The biocidal property of POLYCIDE is very useful in preventing the undesired and harmful growth of algae, fungi and bacteria in various process industries such as breweries, distilleries, baking, confectionery and food processing. It is also used in the preservation of industrial products, such as textile, paper, leather and paint.
POLYCIDE is water miscible product. It can be directly added to cooling water systems and air-conditioning plants to control the growth of algae, fungi, and other microorganisms in water. For general sanitation of premises and equipment of baking, confectionery, food processing, brewing, and distilleries, a dilute solution of POLYCIDE is advised to be used for spraying / rinsing the surface and equipment. For preserving industrial products dilute solution is to be used for coating/impregnation of the finished products.
The quantity of POLYCIDE required to render protection to any particular system will depend on various factors such as the area/volume of the habitat and density of the microorganism to be controlled/killed. As a rule, an intensive dose is followed by my mild dosage after a certain period of intervals as the case may be.
The water ambient temp in cooling system serves a good habitat for algae and fungi. The micellium along with other entrapped matters from gelatinous ‘slime’. The slime formation chokes the flow of water thereby decreasing the heat transfer capacity of the heat exchanger. POLYCIDE can be mixed with water in circulating systems. To prevent slime formation, it acts as Slimicide.
To maintain hygienic condition and to prevent infectious diseases, control of bacterial growth in public was house and swimming pools are necessary. POLYCIDE can be added for this purpose and sanitizing water bodies.
These industries face difficult problem in controlling the growth of bacteria, fungi, algae at various places such as: fermentors, storage tanks, pasteurizers, bottle washing plants particularly in distilleries. Ethyl Alcohol is manufactured by fermentation process of molassess with the help of Yeast. However, the molassess solution contains variety of sacharides, which get converted into organic compound other than Ethyl Alcohol due to bio-oxidation by bacteria present in the molassess solution. This cuts down the yield of alcohol. POLYCIDE can be used to control / prevent the growth of bacteria to improve the yield of alcohol. Following is the recommended dose of POLYCIDE for the desired results.
For optimum control in 1000 liters of fermentation solution of molasses 100 ml of POLYCIDE is to be added which will give a concentration of 10 ppm in the solution of molasses. However, a minimum of 50 ml of POLYCIDE should be added for a concentration of 5 ppm per 1000 liters solution of molasses. POLYCIDE should be added directly to the fermenter containing molasses.
In sugar industries, the fine particles of sugar are blown up along with hot air while sugar is being dried. The exit air after drying sugar contains fine particles of sugar which are removed by scrubbing with water. The water is continuously circulated and the sugar gets dissolved making ‘SWEET WATER”. This sweet water remains in the circulation unit until it reaches a desired concentration of sugar. This sweet water is then sent to the processing plant for the recovery of sugar. During the circulation period, sweet water is susceptible to fermentation caused by bacteria. POLYCIDE can be used to prevent the fermentation of sugar in sweet water, thereby increasing the recovery of sugar.
For optimum control in 1000 liters of sweet water 200 ml of POLYCIDE should be added which will give a concentration of 20 ppm in the bulk sweet water quantity. However, a minimum of 100 ml of POLYCIDE should be used for 1000 liters for a concentration of 10 ppm.
POLYCIDE can be added directly to the sweet water or the desired quantity of POLYCIDE concentrate can be diluted in a bucket of water for convenience of adding it to the sweet water while in circulation or otherwise.
Algal growth on the sand of propagating benches will be prevented by the addition of 10 ml of POLYCIDE solution to every 100 gallons (450 liters) of water used for bench irrigation. Frequency of treatment will depend on the loss of water in its liquid phase from the bench. Under normal conditions, the addition of POLYCIDE to the bench irrigation water should be made twice a month.
POLYCIDE has a long shelf life under normal condition. The solution is alkaline in character and non-corrosive to metals. The material shall be stored in a closed container at room temperature. Use PVC hand glove while handling, Incase of spillage over the body, wash with a sufficient quantity of water. In case of accidental ingestion consult an Industrial physician.
It is not advisable to use POLYCIDE under the following conditions :
