生物活性检测仪BRATTM

Biological Activity Reaction Tests 　　A simple yet effective method for monitoring the population size and/or activity of specific groups or bacteria. 　　　　　　　　 　　　　　 　　 　　Originally designed for the diagnosis of biofouled wells ,BARTTM now has many other applications, including: 　　·Cooling Towers and Heat Exchangers, 　　·Drinking-Water Well Drilling, 　　·Farms and Private Wells, 　　·Hazardous Waste Treatment Facilities, 　　·Municipal Water Treatment (Drinking and Waste waters) 　　·Petroleum: Oil Field Drilling and Refining, 　　·Pools and Spas, 　　·Power Plant Utilities, 　　·Process Water (Manufacturing), 　　·Pulp and Paper Plants. 　　　　　　　　　　　　　TYPES OF BARTTM TESTERS 　　With BARTTM ,you can monitor for Iron Related Bacteria (IRB), Sulfate Reducing Bacteria (SRB), and Heterotrophic Aerobic Bacteria (HAB)-the three most important agents involved in biofouling. These bacteria can cause corrosion, clogging, fouling of the water, and increased hygiene risks, so it is important to have an easy and accurate method of determining their presence and level of activity. 　　　　　　　　　　　　HOW THE BARTTM TEST WORKS 　　　　　　　 　　·EASY TO READ 　　·CAN DO THE TESTS IN THE FIELD 　　·GIVES BACTERIAL AGGRESSIVITY 　　EASY TO USE 　　The BARTTM tester requires no microscope, no laboratory, no incubator! The test is done at room temperature in your office or treatment room, on a desk, shelf, or in a cupboard and is viewed daily. Different microorganisms like to grow at various heights in a column of water to which nutrients have been added. BARTTM testers contain nutrients in the base of the column and a ball. The ball restricts the amount of oxygen entering the water column so that aerobic organisms grow around the ball and anerobic organisms grow deep down in the water column. By changing the nutrients in the base of the column different organisms can be encouraged to grow. BARTTM determines presence and activity levels. 　　EASY TO ANALYZE 　　The time taken for a color change (reaction) to occur gives a measure of the population size and activity . A color change occurs in the BARTTM tube as a result of the oxygen gradient diffusing from the bottom upward. The change of color indicates a presence of bacteria within that sample. Interpretation information is provided with the kit. 　　THE TEST 　　Full instructions for the use of BARTTM biodetectors are included with your purchase. Each individual test consists of : 　　Test vial with media and BARTTM ball, 　　Outer tube for spill containment, odor control, and disposal. 　　Each BARTTM test is color coded for quick and easy recognition: 　　RED- Iron related Bacteria - IRB - BARTTM 　　BLACK - Sulfate Reducing Bacteria - SRB - BARTTM 　　BLUE- Heterotrophic Aerobic Bacteria - HAB - BARTTM 　　LIME GREEN- Slime Forming Bacteria - SLYM - BARTTM 　　DARK GREEN- Micro - Algae - ALGE - BARTTM 　　YELLOW- Fluorescent Pseudomonas - FLOR - BARTTM 　　GREY- Denitrifying Bacteria - DN - BARTTM 　　WHITE - Nitrifying Bacteria - N - BARTTM 　　PURPLE- Acid Producing Bacteria - APB - BARTTM 　　IN DEVELOPMENT 　　BART-READERTM - Computer Assisted BARTTM system; an automated system to provide enhanced information and also for extensive BARTTM use. 　　COLI-BARTTM - A simple 24 hour test for determining Total and Fecal Coliform Bacteria. 　　BOD-BARTTM - An easy 24 hour test for BOD. 　　　　　　　DEFINE THE PROBLEM-IMPLEMENT THE SOLUTION SIMPLE! 　　Establish control and management. 　　Only when the type and extent of the bacteria is defined can proper treatment of your problem begin. BARTTM testers are a valuable tool for diagnosis and management. They are simple to use, require no elaborate or costly equipment, and no specialized training. They are effective and affordable. 　　BARTTMS are also available in the more economical laboratory format (LAB-BARTTM ). 　　Septic Waste and Sewage 　　The Tests 　　Sludge, nightsoil, septic wastes and sewage all possess high organic loadings and present both pollution and hygiene risks. 　　　 　　Common Signs of Microbial Sewage & Septic Problems 　　·Failure to reduce BOD 　　·Unacceptable odors 　　·Equipment failure due to plugging or corrosion 　　·Erratic performance 　　Measure Aggressivity 　　The shorter the time to a positive test, the more aggressive the bacteria are in the sample. If future samples show a shorter time lag ( getting faster ) - the bacteria are becoming more aggressive. If the time lag lengthens then the bacteria are becoming less aggressive. Routine use of the BART tests allows the use to determine how aggressive the bacteria are. This then aids to optimize the effciency of the plant. 　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　DN 　　Denitrifying Bacteria will breakdown nitrates indicating its removal from the wastewater. 　　　　　　　　　 　　　　　　　　　　　　　　　　　HAB 　　Heterotrophic Aerobic Bacteria dominate in aerobic treatment systems. It gives an indication of how efficient the aerobic treatment is by the aggressivity of the bacteria. 　　　　　　　　　　　 　　　　　　　　　　　　　　　　　SRB 　　Sulfate Reducing Bacteria create corrosion risks due to the protection of Hydrogen sulfide. 　　　　　　　 　　·EASY TO READ 　　·CAN DO THE TESTS IN THE FIELD 　　·GIVES BACTERIAL AGGRESSIVITY 　　Available in a Septic and Sewage Combo box consisting of: 　　　　　　　　　 　　·3 DN - BARTs 　　·3 HAB - BARTs 　　·3 SRB - BARTs
