Wastewater Treatment: The Stages of the Wastewater Process
Following coagulation, flocculation occurs when wastewater is gently agitated to create larger, heavier particles called flocs. This step also further prevents any damage to the machines and pumps in the process. The plant cannot treat the water and release it right then since that would cause a large amount of water to be released into the fields twice a day thereby waterlogging the soil. There are deigned equipment which are specially designed to perform all this functions of getting rid of unwanted product in the wastewater. It is meant to remove items such as broken bottles, wipes, sanitary items, diapers among others which may destroy the equipment during the process. Although testing is continuous throughout the wastewater treatment process to ensure optimal water flow, clarification and aeration, final testing is done to make sure the effluent leaving the plant meets permit specifications. Stage Three — Primary Clarifier Initial separation of solid organic matter from wastewater.
8 Wastewaster Treatment Process Steps & Stages
These positively charged chemicals neutralize the negative charge of dissolved particles like dirt. Since this is a massive task, treatment of wastewater is done in three stages; primary, secondary, and tertiary; each of which deals with a different aspect of cleansing. Water can pass through the huge tank in three to six hours Humus and the dead bacteria settle out in another chamber for extra treatment. In this stage, Oxygen O 2 is introduced into the water. Biological water treatment 3.

There is also the option of ozone disinfection, which is particularly good at breaking through microorganism membranes compared to chlorine. Stage 4: Disposal or Use As Biosolid Fertilizer None of the above processes eliminate sludge, so it must go somewhere after treatment. BOD is the quantity of oxygen that is needed by aerobic microorganisms to decompose organic matter in a sample of water. The number of stages of the treatment varies but generally go up to four depending on the quality of water being treated. After any water has been removed, the sludge can be disposed of and is often used as fertilizer. If you're more of a visual learner, the video below does a great job at explaining up to the 8th stage.
What Are the 3 Stages of Wastewater Treatment
The second step is where bacteria convert these organic acids into methane, carbon dioxide and other trace gasses. It further involves the process of converting water into an effluent that can be recycled into the water cycle. The liquid is then pumped through a sedimentation tank, where solid waste settles to the bottom. Drying beds are cheaper alternatives, and they usually have three layers with coarse gravel, fine gravel, and sand to separate the sludge from the water. The final wastewater treatment removes more than 99 percent impurities making the water as close as possible to regular drinking water. It is a very basic process in Wastewater Treatment Plants WWTP.

These bacteria produce sludge that does not settle easily and therefore a possibility that a sludge blanket decanting over the weirs in the sedimentation tank that will severely contaminate the final effluent quality will form. The sludge collected from both clarifiers plus the filter undergoes treatment to produce a usable product fertilizer while also reducing its volume. After going through all the processes, you can still find some diseases causing organisms. Bacteria decompose the suspended waste. On the other hand, if the flow is too fast, the tanks will collect a small amount of sludge, which will affect the water quality downstream.
