With today's advanced technologies, wastewater treatment facilities can eliminate up to 99% of all contaminants from wastewater. Every day brings a new advancement in wastewater treatment, as our expectations for clean water continue to rise.
However, wastewater treatment has not always been as sophisticated. So let's have a look at the creation of the first wastewater treatment facility, the history of wastewater treatment with its importance, and the stages that led to the creation of the current wastewater regulations.
What is the History of wastewater treatment plants?
The aesthetic qualities of water, taste, and odour were the main concerns of early water treatment. Around 1500 B.C., documents from ancient Greece were discovered that described the first straightforward wastewater treatment method. The results show that water was heated to a high temperature, filtered through charcoal, exposed to sunlight, and strained.
At the same time, the ancient Egyptians were the first to use coagulants like alum, to separate pure water from its pollutants. Because, alum is positively charged, it draws in nearby negatively charged water particles. Alum and particles combine to create larger flocs over time, which then settle. Evidence of this primitive technology was discovered on the Tomb of Ramses II. In the treatment of contemporary wastewater, alum is still a frequently utilized coagulant.
In which year water filter was known as Hippocratic Sleeve?
The earliest water filter, known as the "Hippocratic sleeve," was created much later, in 500 B.C. A piece of cloth known as the "Hippocratic sleeve" filtered boiling water to eliminate sediments. Hippocrates, an ancient Greek physician who invented the filter fabric, gave it the name.
Natural waterways ceased to be a sufficient source of water as towns and civilizations grew. As a result, the Romans created the first aqueduct system in 200 B.C. to transfer water from one place, with a bountiful supply to areas with a heavy population.
Aqueducts were ground breaking and the basis for larger cities. After 1000 years, there had been no progress in water purification, and after the fall of the Western Roman Empire, many aqueducts had been demolished, making the future of water look dismal. Before significant attempts could be taken to demonstrate the necessity of clean water, it took many more years as well as pandemics like the Black Death in the late 1400s.
The importance of wastewater treatment experiments finally increased in the early 17th century. The first desalination discoveries were made by Sir Francis Bacon in 1627, setting the stage for subsequent tests. The first scientist to document microorganisms in water treatment was Van Leeuwenhoek in 1676.
In which year water treatment plant was invented and by whom?
Robert Thom, a Scottish engineer, constructed the first wastewater treatment facility at the beginning of the 18th century. The factory used slow sand filters to purify the water before distributing it to everyone, inside the Paisley city limits via an early sewer system.
A sedimentation basin was receiving water from the plant through a bed of dirt and stones. With the aid of coagulants and flocculants, particle settling within the sedimentation basin was hastened by the formation of larger particle flocs. Before the water was kept in a transparent well basin, finer particles were removed in a gravel filter and slow sand filter.
The concept quickly expanded throughout the entire UK and then to Europe, after Thom's initial construction of a wastewater treatment plant.
Importance of Wastewater treatment Plant
Water treatment facilities are made to hasten the purification of water that occurs naturally. The natural process is overburdened by billions of humans and significantly more wastewater. Without wastewater treatment, the volume would wreak havoc, as it still does in developing nations today.
Protecting people and the environment from the hazardous and destructive substances, contained in wastewater is the primary objective of wastewater treatment facilities. Because, the natural process of purifying water is overburdened, water treatment facilities were created to accelerate the natural process. These facilities are used to cleanse wastewater in a variety of ways, before reintroducing the clean water to the environment.
