FiltrationĪt this stage, the floc particles have settled to the bottom of the water supply and the clear water is ready for further treatment.

This simple, low-cost application is a necessary pre-treatment step before the filtration and disinfection stages. For a community water supply, the sedimentation process must happen continuously and in large sedimentation basins. Coagulation makes the sedimentation process more effective because it makes the particles larger and heavier, causing them to sink more quickly. The longer the water sits undisturbed, the more solids will succumb to gravity and fall to the container floor. The second stage takes place when the suspended matter and pathogens settle at the bottom of a container. These particles, called flocs, continue to increase in size with additional mixing and reach an optimum size and strength, preparing them for the next stage in the process. After neutralizing the charge, slightly larger particles called microflocs are formed from the binding of smaller particles with the added chemicals.Īfter coagulation, a gentle mixing known as flocculation occurs, causing microflocs to collide with each other and bond together to form visible suspended particles. In coagulation, positively charged chemicals such as aluminum sulphate, polyaluminum chloride or ferric sulphate are introduced to the water to neutralize the negative charges held by solids, including dirt, clay, and dissolved organic particles. The Centers for Disease Control and Prevention (CDC) ranked the top 10 contaminants in water systems that cause health issues:Ĥ Steps of Community Water Treatment 1. Some of these are chemicals, organisms and pollutants that lead to dangerous health effects such as neurological disorders, gastrointestinal illness, reproductive issues, and increased risks for illness in people with compromised immune systems. and sets the maximum allowable levels for concentrations of various contaminants. The EPA is responsible for regulating the quality of the drinking water in the U.S. Health Risks of Drinking Contaminated Waterĭrinking water has the potential to be contaminated at its source as well as within the water distribution system. Let’s explore some of the risks associated with drinking contaminated water, and the steps involved in mitigating these risks through our water treatment systems with the help of civil engineers who design them.

To make water safe for public consumption, it undergoes a series of treatments and tests on its journey from source to tap. According to the Environmental Protection Agency (EPA), 286 million people get their drinking water from a community water system.
