Origin of sewage

Before the sewage farm was fully operational, George Stayton, an engineer with the sewerage branch of the Roads and Bridges Department and a man "of considerable English experience" [19] recommended that the sewage of the western suburbs of the city also be channelled onto the sewage farm.

Chemical precipitants merely clarified the sewage and retarded the action of nitrifying organisms in any subsequent filtering process.

However, until the Enlightenment eralittle progress was made in water supply and sanitation and the engineering skills of the Romans were largely neglected throughout Europe. Sir Francis Bacon attempted to desalinate sea water by passing the flow through a sand filter.

The paradigm, in turn, strengthened the profession, giving it a set of treatment methods to choose from and allowing it to focus on improving those treatments, which were agreed to be appropriate. The rivalry was not only between artificial or biological filters and land treatment but also between various types of biological filters and contact beds.

Barbara Altarpiece in the National Museum in Warsaw. Stayton argued that the proposed site for the sewage farm was unsuitable because it was low-lying and consisted mainly of clay. His installation fed a concentrated solution of chloride of lime to the water being treated.

The reduction in sludge volume was mainly caused by consolidation in the septic tank and loss of solids with the effluent. The Metropolitan Commission of Sewers was formed at the same time, water filtration was adopted throughout the country, and new water intakes on the Thames were established above Teddington Lock.

Discarding the search for an ideal treatment The Royal Commission into Sewage Disposal played a vital role in the setting of universal sewage treatment standards that enabled engineers to agree over which sewage treatment methods were good enough.

What use was it to achieve a higher degree of purity than was necessary? The Metropolis Water Act introduced the regulation of the water supply companies in Londonincluding minimum standards of water quality for the first time. It had been discovered, however, that organisms in the soil converted the nitrogenous components of dead organic matter into nitrites and nitrates which were harmless and dissolved in water or were taken up by the roots of plants.

The origins of the modern concept of primary and secondary treatment arose from the division of treatment methods considered by the Commission into two stages.

This method would be of use on a large scale, as for service water carts. This community, or a more specialized subset of the community, may in time attempt to create a profession--a group of people who profess to hold a body of specialized knowledge that enables them to treat a certain class of problems and phenomena.

Crops could be grown on the land which would be richer after the sewage had filtered through but this was a secondary consideration since the primary purpose of the Board was to purify the sewage effluent before it went into Botany Bay rather than to utilise the sewage as a fertiliser.

The establishment of the profession of sewerage or public health engineering allowed the domination of the debate by a group of people with common goals and approaches and facilitated the formation of the consensus that was necessary for a paradigm to be formed.

He warned that the area would become surcharged and water-logged with sewage and give off offensive smells.For the enormous quantities of clean water that are piped in, an equal amount of sewage is piped out.

Sewage treatment plan Sewage treatment is the process of removing contaminants from waste water and household sewage, both run off (effluents), domestic, commercial and institutional. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants.

Over the past twenty years, Jon Schladweiler, the Historian of the AZ Water Association, has researched and collected materials related to the history of sewage.

History of Sewage Disposal Throughout history, people have intuitively known that improper disposal of sewage leads to unhealthy living conditions. This is an example of the likely first sewage disposal method used by humans.
