How does tertiary wastewater treatment work?
What Is Tertiary Wastewater Treatment, and How Does It Work? 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 happens to wastewater after tertiary treatment?
Once the wastewater has undergone tertiary treatment, it is ready for discharge back into the environment. Many municipalities have specific requirements about the discharge of treated water, and tertiary treatment should be sufficient to meet those standards, keep the environment clean, and preserve human health.
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, ...
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.
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.
What is the challenge of Puraflo?
One challenge of the current Puraflo system is the media it uses to treat wastewater. Indeed, Puraflo currently uses a by-product of peat briquettes, made from the peat which cannot get used within briquettes.
What is Puraflo system?
The Puraflo system has been designed to accept and evenly distribute the pumped effluent from a packaged wastewater treatment plant. This design incorporates a low-pressure pipe network that is specifically designed and tailored to suit the distance and head from the secondary treatment plant while ensuring the pipe network gets pressurised as per design specifications.
What is tertiary treatment?
Tertiary Treatment of Wastewater – Methods and Process. Tertiary water treatment is the final stage of the multi-stage wastewater cleaning process. This third stage of treatment removes inorganic compounds, bacteria, viruses, and parasites.
What is the final stage of tertiary wastewater treatment?
