Today, filtration and chlorination remain effective treatment techniques for protecting U.S. watersupplies from harmful microbes, although additional advances in disinfection have been made over theyears. nI the 1970s and 1980s, improvements were made in membrane development for reverseosmosis filtration and other treatment techniques such as ozonation. Some treatment advancements havebeen driven by the discovery of chlorine-resistant pathogens in drinking water that can cause illnesseslike hepatitis, gastroenteritis, Legionnaire’s Disease, and cryptosporidiosis. Other advancementsresulted from the need to remove more and more chemicals found in sources of drinking water.

How does reverse osmosis work?
Reverse osmosis involves taking water from the ground and putting it through a process that removes all of the water’s minerals and deionizes it so that it is safe for people to drink. Without this critical process, people would not be able to extract the harmful materials found in natural water and could become sick or die as a result. This process is used in desalinization, which is when ocean water is turned into clean, fresh water. Reverse osmosis helps remove the salt from ocean water leaving behind clean water. The world is running out of fresh and natural resources to use, and 97 percent of the water on the planet is salt water. Reverse osmosis can also help recycle water to make it clean and safe again, and also is used in wastewater treatments.

What is membrane filtration?
Membrane filtration is a streamlined process that helps create clean drinking water. This process is often used to improve food quality, as it helps separate particles from water to create other beverages such as beer, milk and juice. There are four different types of membrane filtration, including nanofiltration, ultra-filtration, reverse osmosis and microfiltration. A different type of filtration process is used for different sized particles. The particles found in salt water are the smallest, so reverse osmosis is used. However, the particles in river water might be larger, so microfiltration is used. Though water filtration is used for a variety of reasons, one is to help create beverages and dairy products in the food industry. This process helps concentrate and purify a variety of foods, from beverages such as beer and vegetable juice to dairy products such as yogurt and cheese. This process is used in several stages of food and beverage development so these products are safe to be sold and used.
