It is an outpatient or office-based procedure. The equipment consists of a vapor generator and a transurethral delivery device. The latter is similar to a cystoscope with an optical system with a 90° extending retractable 10.25 mm long injection needle (diameter 1.3 mm). From this needle water vapor is circumferentially delivered via 12 holes ...
The treatment involves inserting a special microwave urinary catheter into the hyperplastic prostatic urethra. The microwave antenna within the catheter then emits microwaves to heat and destroy the surrounding prostatic tissue. [citation needed] The procedure can take from 30 minutes to one hour and is well tolerated by patients.
Water to be filtered is then applied to the filter surface until the filter clogs and the backwash cycle needs to be repeated. [3]: 264–8 [4]: 10.53–10.58 [5]: 937–9 [6]: 8.11–8.18 [7]: 353–6 Some water treatment filters use surface wash systems that break up the heavily clogged, granular media surface layer.
Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria ...
Dalecarlia Water Treatment Plant, Washington, D.C. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
Once back in the water cycle, the effluent creates an acceptable impact on the environment. It is also possible to reuse it. This process is called water reclamation. [1] The treatment process takes place in a wastewater treatment plant. There are several kinds of wastewater which are treated at the appropriate type of wastewater treatment plant.
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
Advanced oxidation processes (AOPs), in a broad sense, are a set of chemical treatment procedures designed to remove organic (and sometimes inorganic) materials in water and wastewater by oxidation through reactions with hydroxyl radicals (·OH). [1]
