6 Sewage line pipe installation

7 After the grits and inorganic solids are removed, the remaining treated liquid (called effluent) is discharged leaving treated solids (called sludge or biosolids) Storm Sewer

8 Waste water flows by gravity whenever possible
Waste water flows by gravity whenever possible. When this waste is moved against gravity, i.e. up a hill, lift stations are used! A lift station contains pumps to lift waste water on its way to the sewage treatment plant. Lift Station

9 Pumping Station A wastewater treatment plant receives a large percentage of the rain waters from a developed community.  The pumping station moves large volumes of water to the sewage inlet portion of the facility. A supplementary volume of water from rain waters accounts for about 13% of the total volume of wastewater treated at many plants.  This volume of water is negligible compared to that from infiltration, which is estimated at more than 30% of the waters found at the plant.


11 Entering a Waste Water Treatment Facility

12 Waste Water Treatment Basics
(The details are described later on your tour!) Primary treatment uses gravity settling and screening to remove solids from liquid.  Some BOD (biological oxygen demand,) removal. Secondary treatment reduces more BOD concentration. During this treatment,  in an aeration tank, bacteria begins to digest organic material. This process allows for the settling of sludge.  With activated sludge, microbial growth is suspended in the water and will eventually settle out in flocs, called flocculation. This settled sludge can be returned to the incoming water to maintain the necessary biomass for decomposition.

13 Waste Water Treatment Basics
(The details are described later on your tour!) Tertiary treatment takes place in an oxidation tank.  The treatment involves the removal of nitrogen, a element critical for explosive algae and plant growth when in high concentrations.  Once the tertiary treatment is complete, the resulting water theoretically meets drinking water standards.

15 Preliminary Treatment

16 Screening

17 Grit Removal   Grit removal is aimed at doing away with abrasive matter, sands and other heavy particles which could damage sludge treatment mechanical equipment and mire canals and tanks.  

18 Grit Removal Systems Coarse Screen Removal

19 Grit Removal Systems Grid Remover

20 Wastewater Pumps

21 2 1 Primary Treatment Two types of clarifiers, also
known as settling tanks 2 1

22 Primary Clarifier or Settling Tank
Skimmers collect scum at one end of the tank and sludge at the other. Sludge and scum are moved to other areas for treatment. The Primary Clarifier removes about 25% of the pollutants in wastewater.

23 Primary Settling Basin
Influent Waste Water Skimming Collection To secondary treatment To sludge treatment/disposal

24 Phosphorus Removal

25 To reduce the phosphorus in the water, a coagulant, ferric chloride or alum, is added upstream of the screens to destabilize colloidal particles.  An anionic polymer injected at the exit of the grit chambers makes it possible to agglomerate the destabilized particles for flocculation, which rapidly sediment in the clarifiers. Ferric chloride or alum and the anionic polymer are received in a chemical products building.  These chemicals are injected respectively in a manner proportionate to the total phosphorus load and to the flow of raw water.

26 Floc and other matter deposited at the bottom of the clarifiers form sludge.  The matter floating at the surface of the clarifiers is scum.  This sludge and scum are pumped to a sludge building for treatment.

27 Secondary Treatment Aeration Aeration Tank
Following primary treatment is secondary treatment. Primary Treatment is mostly a physical process. Secondary treatment is a combination of physical and biological processes. Secondary Treatment Aeration Aeration Tank

28 Aeration Tank Secondary treatment is speeded up by blowing air in tanks of sewage where micro-organisms float freely & feed on bacteria.

30 Types of Aeration Tanks
(Even though there are different types of aeration tanks, all work in a similar manner, and essentially accomplish the same goals!) One Side Spiral Flow Aeration

31 Types of Aeration Tanks

33 Secondary Treatment After biological treatment in the secondary or aeration tank(s), a secondary clarifier or settling tank removes remaining sludge and pumps it to an on-site sludge handling facility.

34 Secondary Treatment Animation
(Note how air is pumped in at the bottom of the secondary tank.)

35 Secondary Treatment – Trickling Filters

36 Secondary Treatment – Oxidation Ditches

37 Oxidation Ditches Provides mixing, oxygen transfer and retention time for microorganisms to convert organics to more stable compounds.

38 Oxidation Ditches 2 Oxidation Ditch Oxidation Ditch System Rotor

39 Bacteria in Wastewater
Bacteria is where most of the odor comes from! Bacteria in Wastewater

40 Polymer is also added to the water after aeration to aid in a process called flocculation, whereby very small hydroxide particles stick together to form larger particles, called floc, which are more easily settled and removed. The polymer is mixed with the water in a rapid-mix tank

41 Final Clarifiers Following any form of secondary treatment, waste water is settled in tanks to separate the biological sludge from the purified waste water.

42 Final clarifier

43 Types of Final Settling Tanks/Clarifiers
Even though there are different types of final settling tanks, all work in a similar manor and essentially accomplish the same goals! Final Clarifiers allow more detention time for activated sludge to settle, be drawn off gradually, and returned to be mixed with incoming raw sewage, known as Return Activated Sludge.  The process also removes floatable materials by skimming. The effluent water from the clarifiers then goes to the sand filters for further treatment.

50 Disinfection Chlorinator
Treated effluent is disinfected in several ways. Two techniques used are via ultraviolet lamps or chlorination with chlorine gas.

51 Disinfection UV Sterilizer This chamber is lined with ultraviolet lamps.  There are 160 ultraviolet lamps in use in this stage of the plant.

52 Sludge Digestion Sludge Digestion Tank

53 Discharge of Treated Wastewater

54 Tertiary Treatment Sometimes, extra treatment is needed to give the waste water a final "polish". This is known as tertiary treatment. Tertiary treatment is aimed at improving the quality of effluent produced by a conventional biological treatment plant. It is intended that tertiary treatment should polish a good quality effluent. It is not a substitute for inadequate secondary treatment processes.

55 Tertiary treatment can achieve a reduction in suspended solids BOD and ammonia. There are various types of tertiary treatment systems (some have already been mentioned), they are grass plots, clarifiers, sand filters, microstrainers, drum filters, reed beds, lagoons, and nitrifying filters.
