Everyone needs access to clean drinking water, but only some people always have this convenience. While, the essential elements in the water are beneficial to health, the pollutants are also unhealthy. By removing dangerous contaminants from water, a good water treatment system can provide safe drinking water. The water is typically pre-treated by the municipal corporation of your city, making it potable enough.
What about areas where the water supply is untreated?
When water is not properly treated, heavy metals might be a problem! It leads to many questions about what do heavy metals in water represent? Why are they to be eliminated? How can heavy metals be removed from water? Let's investigate.
The effect of heavy metals on drinking water
Natural substances having a high atomic weight, such as heavy metals, have a density at least five times greater than that of water. Human health is negatively impacted by toxic heavy metals such as mercury, cadmium, lead, arsenic, and chromium. For instance, exposure to arsenic through drinking water has been related to cardiovascular disorders, portal fibrosis, diabetes, and hearing issues. Groundwater can also occasionally contain arsenic.
Knowing how dangerous water tainted with heavy metals may be, let's look at how to filter out heavy metals from water.
How can heavy metals be removed from drinking water?
High rates of sickness and mortality are brought on by drinking water, tainted with heavy metals all throughout the world. Since drinking water is the main source of contamination, this has become a worry for both the general public and healthcare experts. Heavy metals can be effectively removed from water by using reverse osmosis.
1: In the reverse osmosis process, water is forced across a semi-permeable membrane under pressure, trapping impurities or solvent on one side while allowing pure water or solvent to pass to the other. Reverse osmosis membranes have a thick barrier layer that only allows water to pass through.
2: Chemical precipitation techniques, such as lime softening, or filtration techniques, like granular media filtration, can be used to remove heavy metals from water. Granular media filtration and lime softening have been shown to be able to remove pollutants, like copper and lead but not arsenic and chromate. Only reverse osmosis can successfully remove all heavy metals without the need for pre-oxidizing arsenic.
Reverse osmosis is therefore required for the treatment of heavy metal pollutants in drinking water, in addition to ultrafiltration and microfiltration.
Pressure is used in the reverse osmosis (RO) process to force a solution across a membrane, which keeps the solute on one side while letting the pure solvent flow to the other. The membrane employed can be a polyamide thin-film composite membrane.
Also, the flow decline differs significantly. The anions in the applied heavy metal salts have a major impact on the flux drop. The membrane separation is significantly impacted by the heavy metal concentration as well. Depending on the transmembrane pressure, the flow drop also varies significantly.
