Every time someone flushes a toilet or washes their hands they waste water. However, this isn’t a bad thing. This wasted water travels down a home’s drain and into a pipe that is connected to a larger sewer pipe in the street. The larger pipe is connected to an even larger pipe that leads to a sewage treatment plant. Sewage treatment is described as the removal of contaminants from water. These plants use chemical, biological, and physical processes to remove contaminants to create safe, usable water. People should know and understand how the sewage treatment process works.
There are four stages to Sewage Treatment in Hawaii. The first stage is screening. The screening process includes removing large items, such as plastic products, diapers, rags, paper, sanitary items, and other large things that can block equipment. This equipment is then used to remove grit from the waste water.
Next, the water receives a primary treatment, which is stage two. In this stage, human waste is separated from the water. To do this, the water is put into large, circular settlement tanks where solids sink to the bottom. The settled solids or sludge is removed by scrapers that constantly scrape the bottom of the tanks pushing the sludge to the center where it gets pumped away. After the pumping is done, the remaining water is removed for secondary treatment.
Secondary treatment is the third stage of Sewage Treatment in Hawaii. In this stage, the wastewater is put into rectangular-shaped tanks called aeration lanes. Here, air is pumped into the water to allow bacteria to break down any small pieces of sludge that may have escaped during the primary treatment.
Stage four is the final treatment of sewage water. This final stage involves passing pre-treated water through another settlement tank. More sludge forms at the bottom of this tank due to bacterial action. It is once again scrapped and pumped for treatment. The water then flows over a wall and is filtered through sand to remove any remaining particles. This filtered water is then pumped back into rivers.
The sewage treatment process is one that many people don’t know about, but should know about. Companies like valley isle pumping work hard to provide water treatment in Hawaii, and the residents should know exactly what this work is. Waste water treatment is a service that keeps water safe to use, and a service that no one could live without.
