Algae the plant like microorganisms are prolific invaders of the open exposed parts of cooling systems such as the tower and the pond areas. They will grow rapidly if conditions are right and only require light; CO2 and water to synthesize their growth. Algae are often visible as green felt-like mats in internal sections of cooling towers that are wet and accessible to sunlight. Algal growth is extremely unsightly and will reduce the efficiency of the cooling tower as a heat exchanger. Loosened deposits will block and foul pipe work and other heat exchange surfaces. The dead cells contribute to the formation of the complex organic material Humus which supports the growth of other microorganisms particularly the anaerobic types. Filamentous and capsulated colonial algae coat splash packing thus interfering with the formation of droplets which aid intimate contact of water and air. Algal growth prevents rainwater from wetting film packing and forming thin films which are Algae also secrete a mucilaginous sheath much like the slime layer in bacteria. The mucilage of the blue-green algae in particular is associated with a peculiar form of movement called gliding that is exhibited when the organism is in contact with a firm surface. These sticky secretions may contribute significantly to complications in cooling systems such as clogged screens and fouled heat exchangers. Many algae produce within their cells malodorous oils and poisonous cyclic alcohols these are released when the organisms die and may cause foul odours. How to Use BS125 - ALGAE TEST KIT Just cut open media pouch and empty contents into the tube provided. Now add water sample to be tested up to red arrow mark. Place the tube on the Energy source. Observe the colour of the tube every day for 4 days. The medium used in AlgroSee has been specially formulated for the growth of a wide variety of Algae species viz green bluegreen brown red etc.

Escherichia coli (E. coli) are commensal mammalian intestine bacteria and normally live in the intestines of people and animals. E. coli is also called faecal coli and causes infections in humans and animals like diarrhoea, severe abdominal cramps, bloody diarrhoea and vomiting. You may be exposed to E. coli from contaminated water or food, especially raw vegetables and undercooked ground beef. The presence of E. coli in any material, system or process suggests a low standard of hygiene and sewage contamination. Therefore all drinking water standards for E. coli TBC test kits, both National and International, are in terms of E. coli. Viz. (0 E. coli in 100 ml of water.) Only E. coli colonies will grow on the BACTASLYDE E. coli bacteria test kit and colonies will be of yellow colour. Since E. coli is the indicator of faecal contamination even a 10 count is alarming as all national and international standards for E. coli are Zero. The Total Bacterial Count with our coliform test kit gives a quantitative idea about the presence of microorganisms such as bacteria, yeast and mould in a sample. The coliform bacteria test kit is also used for Total Viable Count (TVC) Heterotrophic Plate Count (HPC) Heterotrophic Colony Count (HCC) Aerobic Plate Count (APC) Total Plate Count (TPC) or Standard Plate Count (SPC) and it represents the total bacterial load in a given sample. Our range of E. coli testing kits enables you to perform the Total Bacterial Count on one side of the slide to reflect the general hygiene condition of a sample. Contact us today for a reliable and user-friendly E. coli testing kit that gives accurate readings for the total bacterial count of water.

Pseudomonas commonly found in soil or water and is generally in slime form with a consistency range from that of molasses to rubber. It is extremely versatile as it thrives not only in normal atmospheres but also in hypoxic atmospheres and acquires immunity very rapidly to antibiotics. These species are sturdy organisms able to live at very low oxygen tension and difficult to kill. They obtain their energy for living and multiplying either by oxidizing organic compounds or by fermentation. They are more or less free swimming in cooling water and thrive by oxidizing organic substrates to carbon dioxide. It also serves as a biding agent for accumulation of dirt or other organisms and if unchecked can form insulating sticky films on surface where it initiates under deposit corrosion. Pseudomonas is a highly relevant opportunistic human pathogen and has been incriminated in hospital acquired infections in water supplies soaps ice and even disinfectants. Only Pseudomonas species will grow on BACTASLYDE TBC Test Kit and the colonies would be white off white red or green. The Total Bacterial Count gives a quantitative idea about the presence of microorganisms such as bacteria yeast and mold in a sample. It is also known as Total Viable Count (TVC) Heterotrophic Plate Count (HPC) Heterotrophic Colony Count (HCC) Aerobic Plate Count (APC) Total Plate Count (TPC) or Standard Plate Count (SPC) and it represents the total bacterial load in a given sample. All our range of dip slides enables you to perform the Total Bacterial Count on one side of the slide to reflect the general hygiene condition of a sample.
These species commonly occur in soil and water. They are generally slime forming, the slime ranging in consistency from that of molasses to rubber. This serves as a biding agent for accumulation of dirt and if unchecked can form insulating sticky films on surface where heart is exchanged, plug screens and water tubes and initiate under deposit corrosion. Pseudomonas is a highly relevant opportunistic human pathogen. They have been incriminated in hospital acquired infections, in distilled/ demineralised water supplies, soaps, ice and even disinfectants. They are extremely versatile and acquire immunity very rapidly to antibiotics.
