The traditional wastewater treatment plant in the industrialised world relies on outdated systems and networks for wastewater treatment and uses standard methods for level monitoring to control the processes. However, new trends in wastewater treatment and level monitoring are beginning to appear, which may revolutionise how wastewater is handled and treated in the future, drastically improving the efficiency.
Developing countries are early adopters out of necessity
Very often developing countries, as early adopters of new technologies, set the trends in wastewater treatment and level monitoring. They are able to combine existing systems and new technologies as they develop their wastewater treatment networks, and so build modern infrastructure for their growing populations and the increasing demand for clean water.
Modern sewage systems feature separation of the heavily contaminated black water from the less contaminated grey water, using the grey water for wetland construction and irrigation. The most modern systems will also separate rain and storm water from the regular sewage, harvesting rain as a cheaply available source of fresh water. Level monitoring of wastewater plays an important part in each stage of the treatment process as even in the most modern systems, level monitoring solutions are a core component in overall efficiency.
One of the most innovative trends in waste water treatment and level monitoring is to use constructed wetland systems devised to mimic nature in the treatment of water and bacteria. Constructed wetland is flooded with wastewater to let nature biodegrade the contaminated water. As long as they are not overloaded they can consume organic matter and neutralise many pollutants. Where space permits, large lagoons or wetlands can ensure they are not overwhelmed by wastewater and these areas will then be utilised for purification.
Level monitoring technology evolves to suit the need
The trends in wastewater treatment and level monitoring go hand in hand controlling these modern processes and ensuring that wastewater does not pollute the environment. The technology and trends will continue to evolve as developing nations become aware of the dangers of untreated wastewater and increase their need for clean and potable water.
Today, wastewater level is most often measured using submersible pressure transmitters in these developing treatment systems as they are simple to install and will work in environments that few other types of level probes will tolerate.
