How is Groundwater treated using Water Treatment Plants?
Water can be found practically everywhere on Earth's surface, including hills, mountains, plains, and deserts. It is not always available or fresh enough to use without treatment, and it can be difficult to find, measure, and define. This water can be found close to the land's surface, as in a marsh, or hundreds of feet below the surface.
Groundwater is an important component of the natural water cycle. Some precipitation that falls on the ground surface percolates into the sub-soil. Groundwater recharge is the portion that goes downward through the soil until it reaches saturated rock material. Water travels slowly in the saturated groundwater system and may eventually discharge into streams, lakes, and seas.
How much are we relying on groundwater?
-Groundwater serves as a source of drinking water for 71% of the total Indian population and 100% of the rural population.
-Groundwater aids in the growth of our food. 64 percent of groundwater is used for agriculture irrigation.
-Groundwater is an essential component of many industrial operations.
-Groundwater serves as a recharge source for lakes, rivers, and wetlands.
Plants for treating ground water
Groundwater accounts for approximately 35% of public-supply water withdrawals. The removal of impurities such as iron and manganese are one of the most typical problems that water plants face when it comes to groundwater treatment.
Why is there a need to treat groundwater?
The primary goal of treating well water and groundwater is to eliminate dangerous substances such as iron, manganese, ammonia, nitrogen, silt, hard water minerals, and so on, so that the treated water meets the national drinking water standard.
At the moment, well water and groundwater are mostly treated to eliminate iron and manganese. Because the iron and manganese concentration of groundwater in our nation is relatively high.
Aeration and filtration are the primary methods for removing iron and manganese.
Groundwater has a high-water content, a high hardness and alkalinity, a low colloid and suspended material content, and a low colour and turbidity, but it may also contain ferrous ions, manganese ions, silicic acid compounds, and other contaminants. As a result, aeration or oxidation can be employed to pre-treat this sort of water supply, with the goal of oxidising ferrous ions to iron ions before coagulating and filtering. When the “H” content is significant, acid can be used to remove the CO2.If the silicon concentration is excessive, silica fouling can be avoided by using a dispersant, changing the pH and temperature, and so on.
1: Filtration medium is typically composed of quartz sand and manganese sand. It has been filtered using activated carbon and a precision filter. Following treatment, the water quality can essentially meet the national drinking water requirement.
2: The majority of ammonia nitrogen is filtered using ultrafiltration or reverse osmosis, while silt and scale can be filtered using multi-media filtration and ion exchange softening devices.
How are iron and manganese removed?
There are numerous options to addressing this issue, as with other water treatment challenges.
1: Cation exchange: For treating low quantities of dissolved iron, traditional softening resins for iron and manganese removal can be effective. However, it is not suitable for high flows or greater concentrations of iron and manganese, which might impede the resin, resulting in more frequent regenerations and increased waste creation.
2: Two-step oxidation-filtration process, which first oxidises and precipitates the iron and manganese with oxygen, chlorine, or potassium permanganate.The water is next filtered to remove the precipitated particles.One disadvantage of the oxidation filtration strategy is that if iron concentrations are high, the filter medium will need to be back washed more frequently, reducing plant output.
