Kanapaha WRF is treated with an activated sludge process. 

This is a type of treatment that provides the appropriate degree of nutrients to help increase the aerobic microbial activity.

 Kanapaha WRF also uses this process for all other nutrient removal methods including screening, 

flocculation, filtration, and settling tanks which helps provide a combination of multiple nutrient removal processes.

Wastewater at Kanapaha WRF is treated through the following process:

There are multiple stages to this process of treatment which helps provide the most effective and efficient means of removing nutrients from the wastewater.

The main byproduct of this process is sludge, which is a mixture of various organic and inorganic materials. 

Sludge is removed from the treatment facility for further treatment or disposal.

 Wastewater that has already been treated undergoes further testing for potential pathogens before being released into lakes or rivers.

The specific process of activated sludge to help remove nutrients at Kanapaha WRF is as follows.

Water containing the desired nutrients are pumped into one of the many media filters. 

The sludge removal process can be thought of as a filtering system. Wastewater containing the desired nutrients are pumped 

through multiple filters in various media beds where they are separated from other contaminants such as organics and metals.

Bacteria are added to the water while it is being filtered through the media so that the bacterial population can increase.

 Once these bacteria have grown enough, they are removed by pumping them off of the filters. 

These bacteria are then used to break down the sludge that is created in the process of treating wastewater. 

More specifically, they are used to decompose ammonia into nitrite and then into nitrogen gas.

The filters are cleaned of sludge by being backwashed, where the sludge is washed out of the filter. 

Further treatment or disposal of this sludge can then be completed, usually through incineration. 

The clean water that has been filtered is then free of most pollutants and also contains bacteria which are now ready to help filter through more water.

This process is continual and usually operates at night to provide the required amount of nutrients for microbial growth 

for daytime use in treatment processes such as flocculation and filtration.

The first step of the activated sludge process is to aeration. Soil particles are filtered through air bubbles to break them down into smaller pieces. 

Air bubbles are also used to introduce oxygen during the process, which boosts the speed at which bacteria can decompose nutrients. 

The next step is to flocculate, where suspended solids are broken apart into many smaller pieces that bacteria can then use as food sources.

 Flocculation is the process of adding an activated sludge process with nutrients such as nitrogen and phosphorus 

to help the bacteria grow, enabling them to decompose organic matter such as sludge. 

One type of flocculation is acidified flocculation, which is a type of flocculation that uses lactic acid and other acids 

to help break down organic matter. A complicated process known as clarification can be used instead of clarification and clarification and clarification.

 clarification is a complex clarification involving two clarifiers and complexing agents. 

Filtration is the process after flocculation, where suspended solids are removed from water so that water can be reused. 

Finally, effluent is the end product of the activated sludge process that can then be recycled or disposed of.

The bacteria used in the Kanapaha WRF are usually found naturally in landfills. 

These bacteria are often found in decomposing material or even sewage at landfills. 

The bacteria used in the Kanapaha WRF are known as activated sludge process, which consists of mostly mesophilic bacteria,

 heterotrophic bacteria, and anaerobic bacteria. These types of bacteria that are used in the activated sludge process create nitrates that oxidize into nitrogen gas.

The Kanapaha WRF has multiple treatment units for removing nutrients from wastewater. 

All the treatment units are considered to be activated sludge processes, which can vary in complexity.

Sedimentation tanks are used to treat all types of wastewater aside from wastewater that needs a high quality for human consumption. 

Wastewater is pumped into sedimentation tanks where it is mixed with either a fine process media or coarse process media. 

The wastewater is then allowed to settle out and filtered through a bed of activated sludge. 

If a fine process media is used, the effluent from the tank can be reused as fertilizer to grow crops.

 Wastewater if passed through two sedimentation tanks before being treated 

what does the kanapaha wastewater treatment facility use to disinfect the treated water?

can reduce the overall treatment cost because it does not require as much energy to treat.

The effluent from a sedimentation tank is then sent to a grit chamber, where the solids settle to the bottom. 

The water is then cleaned and sent back into the sedimentation tanks for further treatment.
