What are conventional wastewater treatment processes?
Conventional wastewater treatment consists of a combination of physical, chemical, and biological processes and operations to remove solids, organic matter and, sometimes, nutrients from wastewater.
What are the 4 steps of wastewater treatment?
4-Step Wastewater Sludge Treatment Process
- Step 1 – Sludge Thickening. The first step in the sewage sludge treatment plan is called thickening.
- Step 2 – Sludge Digestion. After amassing all the solids from the sewage sludge begins the sludge digestion process.
- Step 3 – Dewatering.
- Step 4 – Disposal.

- Disinfection.
- Storage.
How is wastewater processed?
There are two basic stages in the treat- ment of wastes, primary and secondary, which are outlined here. In the primary stage, solids are allowed to settle and removed from wastewater. The secondary stage uses biological processes to further purify wastewater. Sometimes, these stages are combined into one operation.
Where is conventional wastewater from?
When wastewater enters the aeration tanks, it is mixed with the activated sludge to form a mixture of sludge, carrier water, and influent solids (called mixed liquor). These solids come mainly from the discharges from homes, factories, and businesses.
What is difference between conventional and advanced water treatment?
Conventional water treatment processes, particularly disinfection, should be designed with the removal or inactivation of such viruses in mind….Treatability.
| Water Treatment Process | Purpose |
|---|---|
| Advanced oxidation | Degrade and potentially remove organic chemicals, effective for disinfection |
