Mimiviruses were isolated from sewage or water from cooling towers or seawater, where amoebae exist as their host.
Instead, it uses treated sewage water to cool steam.
In addition, a proportion of clean effluent from the sewage treatment plant is piped to a nearby power station for use as cooling water, saving significant volumes of water and providing revenues to offset operating costs.
This includes the energy to operate the buildings (heating, cooling, electricity demand of appliances), the necessary supporting infrastructure (energy to operate sewage systems, street lighting, road service etc).
So, the irradiation sewage water can find its application either in agriculture for irrigation, in industry for cooling purpose and some selected domestic purposes.
Exchangers are widely used in heating, cooling, air conditioning, power stations, chemical factories, petrochemical factories, oil refineries using them in the processing of natural gas and also used in sewage treatment.
In a power plant that uses steam generators, it could have the added benefit of reducing the amount of water needed to cool the steam condensation and cutting additional sewage costs for getting rid of the extra water, he says.
To cool its three reactors, the Palo Verde nuclear plant in Arizona sources most of the 20,000 gallons it uses per minute from reclaimed sewage from a treatment plant near Phoenix — a technique hailed in 2016 as "a feat of engineering" amid a drought.
In contrast to traditional farms, industrial livestock and poultry facilities keep animals in buildings with mechanized systems for feeding, lighting, sewage flushing, ventilation, heating and cooling, all of which generate emissions.
