Wastewater enters the treatment facility through a 72″ main interceptor into a wet well. The wastewater is pumped up to the 2nd story of the building and from that point is gravity fed through the rest of the plant. On its way to preliminary treatment flow and pH are monitored to alert us of a potential plant upset.
What is the wastewater treatment plant in Fond du Lac?
This plant treats all of Fond du Lac’s wastewater along with that of neighboring communities, approximately 65,000 residents, to prepare the water for discharge into Lake Winnebago.
Where is the wastewater treatment&resource recovery facility located?
An error occurred while retrieving sharing information. Please try again later. The Fond du Lac Regional Wastewater Treatment & Resource Recovery Facility is located on Doty Street, on the south end of Lake Winnebago.
How does waste water treatment plant work?
It works by using aeration and flocculation together. As we have seen, wastewater flows into an aeration tank and becomes mixed with water during aeration. Afterward, the wastewater flows into a settling tank or secondary clarifier.
What do waste treatment facilities do?
A waste water treatment plant cleans sewage and water so that they can be returned to the environment. These plants remove solids and pollutants, break down organic matter and restore the oxygen content of treated water.
What are the 3 steps to wastewater treatment?
The three stages of wastewater treatment are known as primary, secondary and tertiary. Each stage purifies water to a higher level. In some applications, only one or two stages are necessary. The level of treatment necessary depends on the water's intended use case, and what environment it will be discharged into.
What are the 7 steps of wastewater treatment?
Treatment StepsStep 1: Screening and Pumping. ... Step 2: Grit Removal. ... Step 3: Primary Settling. ... Step 4: Aeration / Activated Sludge. ... Step 5: Secondary Settling. ... Step 6: Filtration. ... Step 7: Disinfection. ... Step 8: Oxygen Uptake.
Where does wastewater go after treatment?
The treated wastewater is released into local waterways where it's used again for any number of purposes, such as supplying drinking water, irrigating crops, and sustaining aquatic life.
How do wastewater treatment plants make money?
How to make money from sewage involves a different approach to phosphorus. To extract the phosphorus from sewage, one of the methods is to use microorganisms. The treated microorganisms become a byproduct called sludge cake, which can can be resold to local farmers and used to fertilize their soil.
Which substance is not removed by wastewater treatment facilities?
Biological stages in wastewater treatment plants are not able to remove substances such as drugs, found in the wastewater of medical centers, or halogenated compounds and cyanides from industrial wastewater.
Is the water drinkable after it has been treated?
After treatment, the water is added to the reservoirs. NEWater, which has passed more than 65,000 scientific tests and surpasses World Health Organization drinking water standards, is clean enough to be used for the electronics industry and to be bottled as drinking water.
What are the methods of waste water treatment?
Four common ways to treat wastewater include physical water treatment, biological water treatment, chemical treatment, and sludge treatment.
What are the 4 main steps to water treatment?
Water treatment stepsCoagulation. Coagulation is often the first step in water treatment. ... Flocculation. Flocculation follows the coagulation step. ... Sedimentation. Sedimentation is one of the steps water treatment plants use to separate out solids from the water. ... Filtration. ... Disinfection.
How long does water treatment take?
Any remaining solids bind to the granules as the water percolates down through the materials. Finally, a small amount of sodium hypochlorite and sodium hydroxide are added to the water as it leaves the plant. The entire process takes about five hours.
How many gallons of wastewater is treated in Fond du Lac?
Every day the wastewater treatment plant treats approximately 7-8 million gallons of wastewater in order to protect public health and the environment.
What is Fond du Lac?
Our mission is to operate and maintain the Fond du Lac Regional Wastewater Treatment & Resource Recovery Facility in a cost effective manner, producing effluent water that achieves permit requirements and to recover valuable resources such as energy, biosolids and nutrients to be used in an environmentally beneficial manner.
Why were the 1949, 1964 and 1975 facilities reused?
Elements of the 1949, 1964 and 1975 facilities were reused to provide added features at little or no cost. Facilities from the 1949 plant as well as the 1974 plant were retained to provide additional treatment capacity for abnormally high flows at a low cost to system users.
What is the first step in wastewater treatment?
Often the first step in wastewater treatment is coarse or fine screening to remove large materials (rags, logs and other large objects) or small material (food scraps) from the wastewater that could interfere with the treatment process. The next step is to remove smaller objects (such as sand, broken glass, silt and pebbles).
How is activated sludge formed?
The name “activated sludge” comes from the biological mass formed when oxygen (in the form of air) is continuously injected into the wastewater. In this process, microorganisms are thoroughly mixed with organics under conditions that stimulate their growth. As the microorganisms grow and are mixed by the agitation of the air, ...
What is the BOD of wastewater?
BOD is the amount of oxygen, usually measured in milligrams of oxygen per liter of wastewater, required to decompose the organic nutrients found in the wastewater.
How do you remove solids from wastewater?
Physical – Physical processes were some of the earliest methods to remove solids from wastewater, usually by passing wastewater through screens to remove debris and solids. In addition, solids that are heavier than water will settle out from wastewater by gravity. Particles with entrapped air float to the top of water.
Why are polymers used in wastewater treatment?
Polymers are often used at the later stages of treatment to improve the settling of excess microbiological growth or biosolids. Wastewater enters the treatment facility through a 72″ main interceptor into a wet well. The wastewater is pumped up to the 2nd story of the building and from that point is gravity fed through the rest of the plant.
How deep is a wastewater tank?
Some of these can be removed by gravity in a sedimentation tank. These tanks are typically twelve feet deep and hold the wastewater for two or three hours. What settles out is called sludge.
What chemicals can be added to wastewater?
Simple chemicals such as alum, lime or iron salts can be added to wastewater to cause certain pollutants, such as phosphorus, to floc or bunch together into large, heavier masses which can be removed faster through physical processes.
What is Fond du Lac Regional Wastewater Treatment Facility?
The Fond du Lac Regional Wastewater Treatment & Resource Recovery Facility can arrange to have a speaker come to your organization’s meeting, neighborhood group or classroom to talk about wastewater treatment. We are glad to be in the community and look forward to discussing a range of topics that are of concern or interest to your group.
When can I pick up a brochure for Fond du Lac?
The brochure can be picked up anytime Monday through Friday from 7:00 a.m. to 3:30 p.m.
Pump
Water comes from 17 wells located in and around the city and is pumped to one of four treatment facilities.
Treat
The Water is then treated for disinfection with sodium hypochlorite (chlorine) and radium removal with hydrolyzed manganese oxide (HMO) and run through a greensand filter.
Store
From here the water is sent either to distribution or to a storage facility. The City, on average stores approximately 9.75 million gallons of water for water pressure and fire protection.
Test
System water is constantly tested for chlorine residuals and regularly tested for manganese, bacteria, pH, temperatures, fluoride residuals, inorganics, lead, copper, volatile organics, and radium levels.
