Municipal Water Treatment and Processing of Surface Water

In the early days of its existence, no one had to worry about treating America’s wastewater. Left to nature, the purification process happened slowly but surely. However, now that the number of people has grown by leaps and bounds and more contaminants are ending up in the water supply, steps need to be taken in order to augment nature’s cleaning process. The Clean Water Act of 1972 was enacted to provide a basis for maintaining the nation’s most critical resource, clean water. Municipal water treatment has become a part of our daily lives.

Up until the mid 1900s, the nation’s waterways in urban areas were loaded with pollutants, but no one was really concerned about it. Now, however, we not only understand that clean drinking water is a precious commodity but also that clean water is crucial to maintaining the ecosystems of our world and vital in safeguarding national health. Cities, then, have became responsible for taking the measures necessary to disinfect the wastewater generated in their community and eliminating dangerous pollutants. Municipal water treatment plants were constructed to take care of the problem of filtering the water and making it clean again.

Different 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 over 16,000 water treatment facilities spread all over the country. Municipal water treatment systems begin when wastewater comes into the treatment plant where it is filtered through screens of different densities. Some screens with holes about ½” square eradicate large pollutants from the water, while screens with smaller mesh remove even exceptionally tiny particles.

Ion-exchange resins are usually indispensable in the water purification process. These are made up of insoluble beads with a surface punctured highly-structured pores where ions are easily caught and let go. Ion-exchange resins are utilized successfully to eliminate poisons and heavy metals from water. Once in awhile the resins are mixed with an activated-charcoal filter which has the capabilities to remove organic contaminants from water.

The filtration modes used by municipal water treatment plants are complicated. After all, wastewater can be loaded with microorganisms or pathogens that trigger human diseases. Therefore, the methods used to sanitize the water are all important in the lives of everyone.

In America, there have been a number of types of filtration with varying rates of success going back tp 1892. Today, we have high-tech Municipal water treatment systems that ensure our water will be free from parasites and other harmful organisms that could pose a threat to our health and well being.
