At the onset of its existence, no one had to think about treating America’s wastewater. Left to nature, the purification process took place slowly but surely. However, now that the populace has grown by leaps and bounds and additional contaminants are being allowed to filter into the water supply, steps need to be taken in order to assist with nature’s cleaning process. The Clean Water Act of 1972 was created to act as a basis for maintaining the country’s most valuable resource, clean water. Municipal water treatment has become a part of our daily lives.

Up until the middle of the 20th century, the nation’s waterways in city parts of the country were filled with pollutants, but no one was very concerned about it. In today’s world, however, we not only understand that clean drinking water is a valuable resource but also that clean water is critical in maintaining the ecosystems of our world and vital in maintaining national health. Cities, then, have had to become responsible for taking the measures necessary to clean up the wastewater generated in their community and eliminating toxic pollutants. Municipal water treatment plants were built to handle the issue of filtering the water and making it clean again.

Various types of filtration have been tried with varying amounts of success. Back in 1892, there were only 27 American cities that supplied wastewater treatment for their citizens. Today we have more 16,000 water treatment facilities spread all around the country. Municipal water treatment systems start when wastewater enters the treatment plant where it runs through screens of differing densities. Some screens with holes about ½” square filter out large pollutants from the water, while screens with tinier mesh remove even exceptionally small particulates.

Ion-exchange resins are often used in the water purification process. These are made up of insoluble beads with a surface coated with highly-structured pores where ions are easily trapped and released. Ion-exchange resins are incorporated successfully to eliminate poisons and heavy metals from water. Once in awhile the resins are mixed with an activated-charcoal filter which is able to remove organic contaminants from water.

The filtration processes used by municipal water treatment plants are complex. After all, wastewater can be filled with microorganisms or pathogens that cause human diseases. Therefore, the processes used to decontaminate the water are all important in the lives of people everywhere.

In the U.S., there have been a number of types of filtration with varying degrees of success dating back tp 1892. Today, we have high-tech Municipal water treatment systems that let us be free from parasites and other dangerous organisms that could pose a hazard to our health and well being.
