How to Construct an Industrial Sewage Treatment Plant?
It is wastewater from an industrial setting. Wastewater treatment plants deal with various types of wastewater. Domestic sewage consists of residential toilet wastewater and grey water (wastewater from showers, baths, washing machines, and so on) from homes and apartments. There is storm sewage, which is rainwater and snowmelt that flows into street drains. Finally, industrial sewage refers to waste water from manufacturing plants and factories.
Chemical and pollutant levels in industrial sewage are frequently higher than in domestic sewage or storm runoff!
It could be wastewater from the manufacturing of batteries, the refining of petroleum, or the production of paper in paper mills. This type of wastewater must be handled properly in order for it to be clean enough to be returned to bodies of water or reused in businesses that use the water.
Heavy metals, food waste, inorganic materials such as rubber and metal shavings, microplastics, radionuclides, and a variety of toxins are frequently found in industrial wastewater. As a result, you must treat it properly. None of these should be returned to drinking water storage tanks, rivers, lakes, or other bodies of water. The treatment plant must be built to handle industrial sewage or wastewaters.
Many residential sewage treatment plants are not equipped to handle industrial wastewater. It makes it more difficult to properly treat the water and damage equipment’s, resulting in costly repairs and downtime. An industrial business owner must pause to consider the impact on the local wastewater district. As a result, businesses are considering constructing their own onsite treatment plants to pretreat wastewater before it enters the sewers.
The Process of Industrial Wastewater Treatment-
Solids must be removed from wastewater as it enters a wastewater treatment plant. If they are not removed, they can clog lines and damage downstream equipment’s. Don't let your plant's efficiency suffer as a result of damage or clogs.
Pre-screening is not required when using open screw pumps. Transfer the wastewater to the open screw pumps for grit removal and screening. Additional screw pumps keep the sewage flowing to primary clarification tanks once it arrives.
2. Initial Clarification and Grit Removal
After screening, the wastewater goes through the primary clarification process. Grit removal systems are also required in some plants. Clarification moves the wastewater and aids in the removal of any additional solids that have settled in it. A peripheral feed with a surface skimmer that pushes floating solids into a trough where the solids are removed is an option.
Aeration is the process of stirring up wastewater in order to introduce oxygen into the mix. The oxygen feeds the microorganisms, which aid in the digestion of some of the contaminants that remain in the wastewater. You don't want any small waste particles to settle at this point. Nothing can settle if the wastewater is constantly stirred.
4. Secondary Clarification
At this point, the water is fairly clean, so wastewater is routed to secondary clarification. The procedure is the same as in the primary clarification procedure. Following the other processes, the remaining particles are negatively charged. They will bind, making it easier for the clarifiers to remove the remaining particles.
It's now time to disinfect the cleaned water. Industrial wastewater contains numerous contaminants such as lead, chemical cleaning agents, cyanides, and so on. Disinfection is required to get rid of them. One option is UV disinfection. UV lighting is an environmentally friendly method of disinfection that does not rely on chemicals such as chlorine.
