How is sewage water purified

Wichita Falls is the first U. Texas is currently facing the worst drought recorded in over years, with two thirds of the state in drought conditions. More cities in the South West United States will soon face the decision to reuse and recycle sewage water due to greater risks of drought and the continued scarcity of water in the area.

Joseph Cortruvo, along with many other advocates for this process, say that this is a safe process. Indirect potable water is entirely safe to drink and places across the world without easy access to fresh water already use such processes.

The foreign bacteria rapidly reproduce and consume debris and nutrients in the sewage, but use up all the oxygen in the water in doing so.

The de-oxygenated water is harmful to fish and other aquatic life. Coral reefs are also affected by sewage contaminated water. Water quality is not just important for human health, it is important for the human communities that depend on aquatic and marine ecosystems. Wastewater is treated in 3 phases: primary solid removal , secondary bacterial decomposition , and tertiary extra filtration.

Sewage is generated by residential and industrial establishments. It includes household waste liquid from toilets, baths, showers, kitchens, sinks, and so forth that is disposed of via sewers. In many areas, sewage also includes liquid waste from industry and commerce. The separation and draining of household waste into greywater and blackwater is becoming more common in the developed world.

Greywater is water generated from domestic activities such as laundry, dishwashing, and bathing, and can be reused more readily. Blackwater comes from toilets and contains human waste. Diagram of Sewage Treatment Process : Sewage passes through primary, secondary, and tertiary treatment.

In primary treatment, sewage is stored in a basin where solids sludge can settle to the bottom and oil and lighter substances can rise to the top.

These layers are then removed and then the remaining liquid can be sent to secondary treatment. Sewage sludge is treated in a separate process called sludge digestion.

Secondary treatment removes dissolved and suspended biological matter, often using microorganisms in a controlled environment. Most secondary treatment systems use aerobic bacteria, which consume the organic components of the sewage sugar, fat, and so on. Some systems use fixed film systems, where the bacteria grow on filters, and the water passes through them. Skip to content.
