Diagram titled in blue caps font Waste Water Treatment at top left describes the workflow of waste water treatment from residential home on its 10 step journey to the waterways. Landscape of the diagram is blue sky at the top, green space representing grass in the middle and the bottom depicts a water way connecting to a lake. All the structures described are using a graphic design of navy blue and light blue tones representing any body of water aspect, all pipes connecting everything are olive green. 1- residential home with navy blue caps font next to it, Waste Water From Home Enters Sanitary Sewer; 2 - large gravity filter structure with tank is identified with blue caps font as Primary Treatment: Grit Removal gravity pulls larger particles to the bottom and Primary Clarifier solids are separated from water by settling to the bottom of the clarifier; two green pipes leave that structure, one is item 3 - blue caps font Sludge Solids move to the digester as identified by line pointing to green pipeline and the other is item 4 - blue caps font Liquid and Small Solids point to another section of green pipe; from there material move through to two basins 5 - Aeration Basins: Air is circulated and bugs clean and move phosphorus and nitrates, the moving into item 6, Secondary Clarifier-Additional solids are separated from the liquid and piped back to the biosolids digester; from there the material follows the pipeline to item 7: Sand Filtration in a round tank followed by a trip to item 8: a tank for Disinfection with either UV or Chlorine and from there the pure water goes out to natural water source such as a lake. Now moving back to that second pipe routing to item 3; that material moves to item 9, a large round tank identified as a Digester- a bacterial process called digestion is used to reduce the amount of organic matter and the number of disease causing microorganisms; from that tank the material travels to a pipe to item 10, a building with a tank identified for Dewatering, the last bit of water is removed from the biosolids before it is loaded onto trucks where it will seek its final stop as Biosolids: Nutrient-rich byproducts of waste water treatment, they can be used on hayfields as fertilizer
