Treating billions of Gallons of Wastewater
I think everyone has learnt the knowledge in your primary school, that nature has an amazing ability to cope with small amounts of water wastes and pollution, but it would be overwhelmed if we didn’t treat the billions of gallons of wastewater and sewage produced every day before releasing it back to the environment. That’s why our water resources are seriously polluted and there is no way to control it unless to take some measures for example, to build up a wastewater treatment plant, wastewater treatment plants could help us reduce pollutants in wastewater to a level nature can handle, and control the tense situation.
Before we talk about the wastewater treatment plant let together know something about the wastewater, the wastewater is used water. It includes substances such as human waste, food scraps, oils, soaps and chemicals. In homes, this includes water from sinks, showers, bathtubs, toilets, washing machines and dishwashers. Businesses and industries also contribute their share of used water that must be cleaned. So you see, there are nearly hundreds of wastewater, when designing the wastewater treatment plant as well kinds of professional wastewater treatment plant equipments we must take all these things into consideration.
Do you guys know there need some special permissions when build a wastewater treatment plant? Yes, according to the professional regulation in the world, the new EPP2 regulations we know that any plants, if the local government or some private companies, factories want to build a wastewater treatment plant, they must get some permission which is to pass with the EN12566-3 2005 Certification that are allowed to register for the Discharge Permit or Exemption now required by the Environment Agency.
This step is the primary first one in the whole process of building up a comprehensive wastewater treatment plant, then there are still numerable problems people should to consider.
Another question, What’s the aim of building a wastewater treatment plant?
Well, I have concluded the aims of building a wastewater treatment plant in sentence, The major aim of setting up a wastewater treatment plant is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
According to our current processing ability, a medium-sized wastewater treatment plant could remove about 60 percent of suspended solids from wastewater. This treatment also involves aerating the wastewater, to put oxygen back in. if there is dual processing procedure in our wastewater treatment plant, the secondary treatment removes more than 90 percent of suspended solids.
So to conclude in one word, in order to give our offspring a continuing and sustainable earth and developing space, please take care of everything we get from our nature, and vigorously carrying out the plans of building wastewater treatment plants.
