Waste Water Treatment The treatment of waste water has been the key factor. The methods used take advantage of the natural biological purification process. Let us take a look at what happens to waste water as it goes through a typical treatment plant. Since there are large solid substances in waste water, it is first filtered through a screen to strain out these large solids. Then the water flows slowly through a small basin where the heavy substances, such as sand, sink to the bottom, from where they are cleared away. This basin is called a grit chamber. Next the water flows into a large sedimentation basin, where it moves slowly for one or two hours. Here the dirt or sludge in the water sinks to the bottom, from where it can be pumped out. At this point, however, there are still a lot of organic substances in the waste water. So the water is next channeled into the biological stage for “high-powered treatment” by microorganisms. In large treatment plants this is generally done by adding a concentration of microorganisms to the waste water when it comes into the aeration tank. As the tank’s name suggests, plain oxygen is blown into the water. The microorganisms now have an abundance of both oxygen and food in the waste water. So they multiply rapidly and effectively break down the impurities. After this, a clarification tank is needed to separate the microorganisms from the purified water. They sink to the bottom in this tank and the relatively clean water can now be discharged into the lakes or rivers. However, such water may still contain much bacteria, some of which could cause disease. For that reason this water is disinfected with, for example, ozone and hydrogen to kill dangerous bacteria.
