In the wastewater industry, plants often focus on primary and secondary treatments, which do most of the work of preparing wastewater for discharge into the environment. Tertiary treatment is also critical in many situations. It affords the peace of mind of knowing ...
What is secondary treatment?
Secondary treatment applies additional biological processes like aeration and activated sludge treatment to break down dissolved and suspended biosolids using good bacteria. Tertiary treatment adds a third, more advanced and rigorous level of treatment.
Why is chlorine used in wastewater treatment?
Wastewater treatment plants can dump chlorine into the wastewater to kill harmful microorganisms like bacteria and viruses.
What is wastewater treatment?
Most wastewater treatment systems consist of at least two main treatment processes: primary and secondary treatment, with some additional preliminary methods. Primary treatment, which typically removes 50% to 70% of the suspended solids in wastewater, uses physical processes like filtration and settling to remove grit, debris, oil, ...
Does UV light kill bacteria?
Ultraviolet light does not typically kill viruses and bacteria, but it renders them unable to infect humans or wildlife. The effluent must have received aggressive treatment beforehand, though, because any residual organic matter can shield the microorganisms from the UV light.
What are the different types of filters?
The filters also come in a few different types, including bag filters, drum filters and disc filters: Bag filters: Bag filters are ideal for wastewater treatment plants that need to reduce contaminants to a specific micron rating.
Is chlorine better than chlorine?
It is safer than chlorine because plants can generate it on-site as needed rather than storing it over the long term and risking a toxic leak. It also will not form hazardous byproducts in the water. The treatment equipment is relatively expensive to maintain, however.
What Does Tertiary Treatment Mean?
Tertiary treatment in waste water is the third and final advanced treatment process used to disinfect water that has already been treated by primary and secondary processes for removing harmful material in a waste water plant. This produces high quality, usable water.
Safeopedia Explains Tertiary Treatment
This final stage of water treatment is any treatment, going beyond primary and secondary, and is often a disinfection process that can involve the use of ultraviolet (UV) light or chemicals, such as lime, to eliminate pathogens (bacteria or viruses) from the water.
What is tertiary treatment?
Tertiary treatment is the third, and final, stage in a standard wastewater management system. Once effluent has been treated in the primary and secondary stages by removing suspended solids, pH balancing and reducing its biochemical oxygen demand (BOD), it is ready to enter the tertiary stage.
Why is tertiary treatment important?
Incorporating a tertiary treatment system into your operation can dramatically reduce the amount of water your facility uses, which is becoming increasingly important to regions, states, and localities that face shortages.
How long does it take to install a tertiary treatment system?
After collecting data and making a system recommendation, we’ll begin the 2-3 week process of installing your tertiary treatment system. Once the installation is complete, we’ll compile documentation and create a custom service checklist that’s specific to the customer’s site and system.
Is gray water better than black water?
It is much easier to reuse gray water (processed wastewater) than blackwater. For high strength wastewater, it is critically important to reduce both the organic loading (BOD) as well as the suspended solids (TSS) to make final stage treatment feasible.
What is tertiary treatment?
What is Tertiary Sewage Treatment? After biochemical degradation of the sewage in the secondary treatment, the clarified effluent is further treated to treat it of the non-biodegradable toxic organic pollutants such as chlorophenols, polychlorinated biphenyls and other synthetic pollutants.
What is the process of filtration?
Filtration. In the filtration process, either sand, charcoal or activated carbon are used to filter the wastewater. The water is made to pass through a bed of sand or charcoal, so that the particulate matter in the water adheres to the filter medium and gets removed from the water. Lagooning.
How is nitrogen removed from wastewater?
Nitrogen is removed by volatiIisation as ammonia. Ammoniacal nitrogen is removed by breakpoint chlorination by adding hypochlorous acid in 1:1 ratio. Disinfection. The final step of tertiary process is disinfection, which is typically carried out by adding chlorine to the wastewater.
What metals are removed from sewage?
For this purposes activated carbon filters are used. Removal of heavy metals like mercury, lead, chromium and cadmium are also done during tertiary treatment. These metal ions, which are found absorbed in the sewage water are converted into either toxic products or residues.

To remove the chlorine, a compound called sodium ...
What is the primary treatment of wastewater?
Primary treatment of wastewater involves filtering out large solid contaminants. Secondary treatment then purifies the wastewater through biofiltration, aeration, and oxidation. These are all processes that help to remove sediment from the water.
What is alum used for in water treatment?
When needed, it sometimes involves using alum to remove phosphorus particles from the water. Alum also causes any solids that were not removed by primary and secondary wastewater treatment to group so they can be removed by filters.
What is the purpose of chlorination in wastewater treatment?
Chlorination in wastewater treatment kills bacteria and viruses, and eliminates parasites such as Giardia and Cryptosporidium, which can cause very serious illnesses. In summary, this process disinfects water so that it is safe to reuse or recycle.
How does chlorine affect water quality?
Chlorine also reduces biological water quality when it is present in high concentrations. To remove the chlorine, a compound called sodium bisulfite is added to the water. Chlorine ions in the water react with this chemical and are removed.
