What is waste water treatment?
Wastewater treatment is a process used to remove contaminants from wastewater and convert it into an effluent that can be returned to the water cycle.Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation).
What is municipal wastewater treatment?
Wastewater treatment uses various biological conditions to allow the polluted wastewater to treat itself. In summary, it’s creating a controlled environment where pollutants can safely break down and become less harmful to the environment. Why Do Municipalities Treat Wastewater?
How long have wastewater treatment plants existed?
In 1804 the first actual municipal water treatment plant designed by Robert Thom, was built in Scotland. The water treatment was based on slow sand filtration, and horse and cart distributed the water. Some three years later, the first water pipes were installed.
When was drainage system invented?

What are the origins of municipal wastewater treatment?
Cities began to install wastewater collection systems in the late nineteenth century because of an increasing awareness of waterborne disease and the popularity of indoor plumbing and flush toilets.
When did running water become available?
Early 20th Century Plumbing By the turn of the century and into the early 1900s, running water became more accessible to the average home. Still, most could not afford indoor plumbing and relied on outhouses and well pumps. By the 1930s, both running water and indoor plumbing were widely available.
Who invented wastewater treatment?
The first wastewater treatment plant was introduced in the early 18th century by Robert Thom in Scotland. The plant used slow sand filters for water purification and distributed the water trough an early sewer system to everyone within the city limits of Paisley.

What was the main driving force between the earliest water treatments?
Turbidity was the main driving force between the earliest water treatments. Not much was known about micro organisms, or chemical contaminants. After 1500 BC, the Egyptians first discovered the principle of coagulation. They applied the chemical alum for suspended particle settlement.
When was the first water filter invented?
In 1676, Van Leeuwenhoek first observed water micro organisms. In the 1700s the first water filters for domestic application were applied. These were made of wool, sponge and charcoal. In 1804 the first actual municipal water treatment plant designed by Robert Thom, was built in Scotland.
Why did the 1890s use sand filters?
In the 1890s America started building large sand filters to protect public health. These turned out to be a success. Instead of slow sand filtration, rapid sand filtration was now applied. Filter capacity was improved by cleaning it with powerful jet steam. Subsequently, Dr. Fuller found that rapid sand filtration worked much better when it was preceded by coagulation and sedimentation techniques. Meanwhile, such waterborne illnesses as cholera and typhoid became less and less common as water chlorination won terrain throughout the world.
How did the Romans get water?
The Assyrians built the first structure that could carry water from one place to another in the 7th century BC. It was 10 meters high and 300 meters long, and carried the water 80 kilometres across a valley to Nineveh. Later, the Romans started building many of these structures. They named them aqueducts. In Latin, aqua means ‘water’, and ducere means ‘to lead’. Roman aqueducts were very sophisticated pieces of engineering that were powered entirely by gravity, and carried water over extremely large distances. They were applied specifically to supply water to the big cities and industrial areas of the Roman Empire. In the city of Rome alone more than 400 km of aqueduct were present, and it took over 500 years to complete all eleven of them. Most of the aqueducts were underground structures, to protect them in times of was and to prevent pollution. Together, they supplied Rome with over one million cubic meters of water on a daily basis. Today, aqueducts can still be found on some locations in France, Germany, Spain and Turkey. The United States have even taken up building aqueducts to supply the big cities with water again. Many of the techniques the Romans used in their aqueducts can be seen in modern-day sewers and water transport systems.
Why was water purified?
The major motive for water purification was better tasting drinking water, because people could not yet distinguish between foul and clean water. Turbidity was the main driving force between the earliest water treatments. Not much was known about micro organisms, or chemical contaminants.

In ancient civilizations, cities were usually established around sources of water such as rivers and streams as is the case today as well.
Did ancient civilizations make advances in purifying water?
These writings showed that even in ancient civilizations they were making advances in purifying water which is pretty amazing since we still use these base technologies today.
When did water treatment become less sophisticated?
Water Treatment Is Reborn after Fading Away. Water treatment in the Middle Ages ( 500-1500 AD) became less sophisticated, as the Roman aqueducts fell into disrepair with the collapse of the Roman Empire. In these times, relatively little was done to ensure public access to a clean water supply.
Why did cities install water filters?
The water had smelled and tasted fine, so this was when they figured out that that’s not enough to guarantee the safety of the water. As a result, cities began installing municipal water filters, and government regulation of water started to become the norm.
Why were the aqueducts built underground?
Most of them were built underground to keep them safe from pollution and war. They supplied Rome with over 250 million gallons of water per day, and many still stand in Spain, Turkey, Germany, and France. Many of the techniques used in these aqueducts are still being used to build modern water transport systems today.
What did Francis Bacon do to improve water treatment?
Sir Francis Bacon restarted the advancement of water treatment practices in 1627, when he began experiments in seawater desalination. He tried to use sand filtration to filter salt out of saltwater. His experiment didn’t succeed, but he laid the groundwork for other scientists to get involved in the field.
What were the major public health concerns around drinking water?
This was also when the major public health concerns around drinking water shifted from disease-causing bacteria to man-made pollutants such as pesticides, chemicals, and industrial sludge. New regulations addressed water contamination and waste from industrial processes, and water treatment plants adapted to the new threats. They applied new techniques including active carbon adsorption, aeration, and flocculation.
Why did people purify water?
Their primary motivation in doing this was to make water taste better, as they couldn’t yet distinguish between water that’s clean and water that’s foul.
When was coagulation first discovered?
The Egyptians first discovered the principle of coagulation around 1500 BC. They used alum to achieve suspended particle settlement, as depicted on the wall of the tomb of Amenophis II and Ramses II. Hippocrates first started discovering water’s healing properties around 500 BC.
