What is OBR in DM plant?
OBR in a DM (Demineralization) plant refers to "Online Blowdown Regulation." It is a process used to control the concentration of dissolved solids in the demineralized water by periodically removing a portion of the water (blowdown) to maintain water quality. This helps prevent scaling and fouling in the system, ensuring efficient operation of the plant. Proper OBR management is crucial for optimizing the performance and longevity of the demineralization process.
What is the unit of conductivity of dm water?
Unit of dm water conductivity is microsiemens/cm
How many dm in a liter of water?
One liter of water is equivalent to 1,000 cubic centimeters (cm³). Since one cubic decimeter (dm³) is equal to 1,000 cm³, this means that there is 1 dm³ in a liter of water. Therefore, there is 1 dm in a liter of water.
Why is it important for a community to maintain safe water quality in its watershed?
Many diseases can be transmitted by water.
How often should flushing water lines be performed to maintain optimal water quality and system efficiency?
Water lines should be flushed regularly to maintain optimal water quality and system efficiency. It is recommended to flush water lines at least once a year to remove any buildup of sediment, minerals, or bacteria that can affect water quality and system performance.
What is role of CO2 breather arrangement in DM storage tank?
High quality of DM water is important for such industries as power generation, semiconductor and pharmaceutical where there are strict regulatory requirements. The most common way to measure very low levels of ionic impurities in ultra pure water is on line analysis of conductivity and resistivity. DM water is often exposed to CO2 from the air, which increases its conductivity and gives the appearance of a contaminant in the water. Depending on CO2 concentration in incoming air water conductivity can be increased to ~0.8-1.5 µS/cm. CO2 breather or CO2 Scrubber for DM Tanks allows you to keep stable pH and low conductivity of DM water.
How DM plant are design?
Since there is continuous withdrawal of steam and continuous return of condensate to the boiler, losses due to blowdown and leakages have to be made up to maintain a desired water level in the boiler steam drum. For this, continuous make-up water is added to the boiler water system. Impurities in the raw water input to the plant generally consist of calcium and magnesium salts which impart hardness to the water. Hardness in the make-up water to the boiler will form deposits on the tube water surfaces which will lead to overheating and failure of the tubes. Thus, the salts have to be removed from the water, and that is done by a water demineralising treatment plant (DM). A DM plant generally consists of cation, anion, and mixed bed exchangers. Any ions in the final water from this process consist essentially of hydrogen ions and hydroxide ions, which recombine to form pure water. Very pure DM water becomes highly corrosive once it absorbs oxygen from the atmosphere because of its very high affinity for oxygen. The capacity of the DM plant is dictated by the type and quantity of salts in the raw water input. However, some storage is essential as the DM plant may be down for maintenance. For this purpose, a storage tank is installed from which DM water is continuously withdrawn for boiler make-up. The storage tank for DM water is made from materials not affected by corrosive water, such as PVC. The piping and valves are generally of stainless steel. Sometimes, a steam blanketing arrangement or stainless steel doughnut float is provided on top of the water in the tank to avoid contact with air. DM water make-up is generally added at the steam space of the surface condenser (i.e., the vacuum side). This arrangement not only sprays the water but also DM water gets deaerated, with the dissolved gases being removed by an air ejector attached to the condenser.
How often should I change my water filter to ensure optimal performance and water quality?
Water filters should typically be changed every 6 months to maintain optimal performance and water quality.
How often should fountain cleaning be performed to maintain optimal water quality and prevent algae growth?
Fountain cleaning should be performed every 1-2 weeks to maintain optimal water quality and prevent algae growth.
What is the main reason scientists monitor the water quality of streams lakes and other water sources?
to maintain a clean environment .
