What is an Industrial Wastewater Treatment System and How Does it Work?
For industrial companies producing wastewater as part of its process, some type of wastewater treatment system is usually necessary to ensure safety precautions and discharge regulations are met. The most appropriate industrial wastewater treatment system will help the facility avoid harming the environment, human health, and a facility’s process or products (especially if the wastewater is being reused). It will also help the facility curb heavy fines and possible legal action if wastewater is being improperly discharged into a POTW (publicly owned treatment works) or to the environment (usually under a National Pollutant Discharge Elimination System, or NPDES, permit).
What is TSS in wastewater?
Total suspended solids (TSS) in wastewater, the organic and inorganic solid material suspended in the water, can, like many of the other contaminants listed, harm aquatic life. They can also be problematic if the wastewater is being reused for a process, so depending on whether or not you need to discharge your wastewater in a publicly owned treatment works (POTW) or environment, or reuse the wastewater for process, will determine how harmful the TSS will be. TSS can decrease levels of oxygen in aquatic environments and kill of insects. They can also scale and foul piping and machinery.
How does dewatering work?
The dewatering process takes all the water out of the sludge with filter or belt presses, yielding a solid cake. The sludge water is put onto the press and runs between two belts that squeeze the water out, and the sludge is then put into a big hopper that goes to either a landfill or a place that reuses the sludge. The water from this process is typically reused and added to the front end of the clarifier.
What happens if nitrates are not removed from wastewater?
If large amounts of nitrates and/or phosphates are not removed from wastewater and these nutrients are discharged into local environments, they can lead to an increase BOD and extensive weed growth, algae, and phytoplankton.
What are the diseases that can be caused by wastewater?
When domestic or industrial wastewater contains these harmful pathogens and is not treated, it can spread illnesses and diseases such as cholera, dysentery, salmonellosis, hepatitis A, botulism, and giardiasis, to name a few.

How Does A Wastewater Treatment System Work?
- Specific treatment processes vary, but a typical wastewater treatment facility process will usually include the following steps:
Other Possible Steps to The Wastewater Treatment Process
- Lime softening
In waters where you have high hardness or sulfates, or other constituents you need to precipitate or take out, a lime and/or a lime soda process is used. It raises the pH, causing hardness and metals in the water to precipitate out. Cold, warm, or hot lime processes can be used, and each … - Ion exchange softening
In some industrial and municipal applications, if there’s high hardness, there may be post treatment for the removal of the hardness. Instead of lime, a softening resin can be used; a strong acid cation exchange process, whereby resin is charged with a sodium ion, and as the hardness …
