A high standard of living involves a high demand for water and, at the same time, causes much greater pollution of this essential element for life. The resultant interference in the natural cycle can often overwhelm natural processes of recovery, so that, in addition to products arising from the decomposition of natural substances (e.g., proteins, greases, carbohydrates) there is a build-up of anthropogenous additives such as pesticides, effluents and garbage, which contaminate drinking water supplies with their toxic or hormonal effects. They may also consume such large quantities of oxygen that water resources become fouled. To prevent the threat of possible danger to health, or the very existence of certain species, it is essential to determine the quality of a water source before water is drawn off for consumption. In this post, we will learn more about the Water quality testing methods such ads use of BOD Incubator.
Water quality is dependent on its constituents, which can be divided into organic and inorganic substances. Given the wide range of natural and synthetic compounds which exist, an analysis of the individual constituents is not a practical proposition and, in any case, a complex affair. In practice, in order to arrive at significant milestones which will permit an evaluation of water quality, rapid methods of analysis are used which consider groups of parameters, rather than the individual parameters themselves. In this connection, BOD is employed to determine the aerobic destructibility of organic substances. As long ago as 1870, Frankland carried out the first BOD measurements, which were very similar to the dilution method in use today.
Presto’s BOD incubator or Biochemical oxygen demand incubator is a unique chamber with latest technology based features used to create the required temperature. The testing instrument has the low heat loss ratio due to the high eminence of insulation with imported glass wool ergonomics. The machine is designed keeping in mind the user ease as an important parameter.
Important features of the testing instrument:
- The instrument permits the measurement of contaminants, treating them and releasing them back to the environment.
- Temperature controls through PT-100 sensor
- Highly accurate test results under uniform temperatures level in the chamber
- High Grade imported Glass Wool insulation
- Maximum Thermal Efficiency by insulation means.
- SSR-based heaters
- Fan relay for Fan operation
