Water Treatment Technology
Getting to Know Essential water treatment technologies
Proper water treatment is important for living a disease free life while fueling the body to continue its many functions, but how exactly does this process work and what are some of the tools involved? This article will talk about the unique processes and functional technologies needed.
Screens are the first water treatment technology used when processing water. The use of screens removes both large and small debris from the unprocessed liquid. The process is broken down into two parts.
Part one removes large debris with a coarse mesh, typically sized above .25 inches, perfect for large solids, rags, bottles, sticks, etc.
Part two is when you remove smaller solid contaminants using a fine screen, which is sized below .25 inches all the way to .06 inches.
If you want to go lower, you’re looking at .01 inches, but now you’re in the “very fine screen” zone, which can be an additional step or the second step or replaces fine screen operations.
After the screening, there are still solid particles that come together to form rag balls, which threaten to tie up the treatment process. They have to be separated using the sharp rotating blades of a grinder before they are given to the gravel filters.
3. Gravel filters/Grit chambers
Algae, fine sand, gravel, and other unresolved solids with the water solution are fed into a tank where they settle over some time. Gravity acts to pull the heavier material to the bottom of the chamber, where they will be transported to be disposed of accordingly. The remaining liquid channels to another chamber, further propagating the process as not all solids are out as yet.
4. Slow sand filters
Contact with microorganisms is initiated unless ozone was added at the beginning of the process to reduce smell, but that will be discussed further. Water is sent to a tank containing sand, which acts as a purifier as water is allowed to drain through. It’s a straightforward process. It only requires sand and land.
5. Activated carbon filters
Activated carbon/charcoal filters are the most popular water treatment products available. When contacted by the water, the carbon surface acts as a magnet to volatile compounds and dangerous air molecules present in the mixture. For this reason, you’ll find them in many homes on tap water systems as incoming water pipes may contain impurities.
6. Oxidation tanks
At this stage, the liquid may still not be fully potable due to gases present in its aquatic atmosphere. For this reason, oxygen is added to evict carbon dioxide, combust heavy metals and enlarge tiny particles to where they can be seen and dealt with accordingly.
7. Membrane technologies
Reverse osmosis filters are among the water treatment products available commercially for households. They force concentrated water (water mixed with other chemicals) through a thin membrane that arrests the chemicals while allowing water to pass through freely.
8. UV light filters
UV filters work by exposing living bacterial organisms to direct UV light, which cripples them and halt
their reproduction process, hence rendering them useless. This is the sanitation process after water filtration to attack dangerous disease-causing agents.
9. Ozone chambers
This is an essential water treatment technology that add ozone to the solution, either before, during, or after the water filtration process, to ensure the disease-causing bacteria does not survive. Ozone works by tearing the molecules apart from the inside out.
