Compared to 7.7 billion in 2019, the earth would be home to 9.7 billion people by 2050, says the United Nations, in its 2019 World Population Prospects report. With population boom, the demand for everything, be it food, water, clothes, housing, or medicines, will rise too. Plus, with the prevalence of chronic diseases surging, prescription as well as over-the-counter (OTC) drugs are needed more than ever. This is leading to huge investments in the pharmaceutical industry, wherein new production plants as well as research laboratories are being set up. At both these places, filtration is one of the most important processes, as the drugs being produced or researched upon must be completely contamination-free.
