2. Dosing - Wikipedia

   en.wikipedia.org/wiki/Dosing

   Commercial swimming pools also require chemical dosing in order to control pH balance, chlorine level, and other such water quality criteria. Modern swimming pool plant will have bulk storage of chemicals held in separate dosing tanks , and will have automated controls and dosing pumps to top up the various chemicals as required to control the ...

3. Metering pump - Wikipedia

   en.wikipedia.org/wiki/Metering_pump

   Pumps used in high-pressure chromatography such as HPLC and ion chromatography are much like small piston metering pumps. For wear resistance and chemical resistance to solvents, etc., typically the pistons are made of artificial sapphire and the ball check valves have ruby balls and sapphire seats.

4. Peristaltic pump - Wikipedia

   en.wikipedia.org/wiki/Peristaltic_pump

   A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.

5. Boiler feedwater - Wikipedia

   en.wikipedia.org/wiki/Boiler_feedwater

   Chemicals are put into boiler water through the chemical feed tank to keep the water within chemical range. These chemicals are mostly oxygen scavengers and phosphates. The boiler water also has frequent blowdowns in order to keep the chloride content down. The boiler operations also include bottom blows in order to get rid of solids.

A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.

7. Steam and water analysis system - Wikipedia

   en.wikipedia.org/wiki/Steam_and_water_analysis...

   Monitoring the pH value of the feed water gives direct indication of alkalinity or acidity of this water. The ultra pure water has pH value of 7. In steam circuit it is normal practice to keep the pH value of feed water at slightly alkaline levels using chemical dosing. This helps in preventing the corrosion of pipe work and other equipment.
