What is wastewater treatment plant?
A wastewater treatment plant is a facility in which a combination of various processes ( e.g., physical, chemical and biological) are used to treat industrial wastewater and remove pollutants (Hreiz et al., 2015).
How is wastewater treatment plant design based?
Wastewater treatment plant design is based on the selection and sequencing of various unit operations. A schematic illustrating integration of processes capable of treating a variety of wastewaters is shown in Figure 1. Selection of a combination of processes depends on the characteristics of the wastewaters; the required effluent quality (including potential future restrictions); costs; and, availability of land. As previously indicated, treatment methods can be classified as pretreatment/primary treatment; secondary treatment; tertiary treatment; sludge treatment/stabilization; and, ultimate disposition or reuse treatment technologies for residuals.
What is WWTP in wastewater treatment?
WWTPs are a significant point source for AMRDs and antimicrobials. WWTPs are relatively nutrient-rich, heavily contaminated environments that receive waste from a variety of AMRD-loaded environments, including hospitals, industrial and agricultural sites and release both solid and liquid by-products that can disseminate AMRDs. Influent can be contaminated with a variety of pollutants, including antimicrobial agents, pharmaceuticals, personal care products, and heavy metals, which can accumulate within WWTPs. Many microbial and chemical contaminants in wastewater cannot be degraded by the treatment process or inactivated through disinfection of the effluent. For those contaminants that can be degraded, the resulting metabolites may still have antimicrobial or selective activity. WWTP effluent and solid waste products not only have a high prevalence of AMRDs but also release selective agents into the receiving environments ( Jury et al., 2011 ).
What is reclaimed water?
Reclaimed wastewater is usually clean enough to be used for irrigation, but usually contains higher (~1.5 times) concentrations of dissolved solids than the source water. Also, chlorine-disinfected reclaimed water can contain significant trace amounts of disinfection by-products such as trihalomethanes and haloacetic acids.
How did the treatment plant get to net zero?
It made its operations and equipment more efficient (cutting energy consumption), but mostly it got to net zero by producing renewable energy on site. This is the fats, oils and grease receiving station.
What is the purpose of sodium hypochlorite in wastewater treatment?
The wastewater is then disinfected with sodium hypochlorite to remove any disease-causing organisms and ensure that water leaving the plant meets the water quality standards set by the Environmental Protection Agency (EPA). Following the treatment, the water is discharged to the Columbia River.
What is the mass of solids in a sedimentation tank called?
The remaining solids are minute particles that fall to the bottom of a sedimentation tank. The particles form a mass of solids called biosolids or sludge.

How does a sewage treatment plant filter wastewater?
The wastewater that enters the sewage treatment plant is first filtered through bar screens, a process known as screening. The bar screen separates large trash objects from the wastewater, such as rags, sticks, cans, plastic bags, napkins, sanitary towels, and so on. As a result, screening removes large pieces of trash from the wastewater.
What is the solid component of sewage?
The majority of the solid organic matter (faeces, for example) settles as sludge on the sloping bottom of the sedimentation tank. As a result, the solid component of sewage is known as sludge .
Why is activated sludge returned to the aeration tank?
Some of the activated sludge is returned to the aeration tank to boost the population of aerobic bacteria and accelerate the cleaning of watery waste. The digester tank receives the remaining activated sludge. The water in the second sedimentation tank contains very little organic material and suspended matter.
What is WWTP in water treatment?
