Slingshot is a water purification device created by inventor Dean Kamen. [1] Powered by a Stirling engine running on a combustible fuel source, it claims to be able to produce drinking water from almost any source [2] by means of vapor compression distillation, [3] requires no filters, and can operate using cow dung as fuel.
Aquaver membrane distillation units are focused at desalination, [2] industrial water treatment, [3] and 'difficult-to-treat' waters. In February 2014 Aquaver commissioned in Gulhi, Maldives, the world's first desalination plant based on membrane distillation.
Spermicide is a contraceptive substance that destroys sperm, inserted vaginally prior to intercourse to prevent pregnancy.As a contraceptive, spermicide may be used alone. However, the pregnancy rate experienced by couples using only spermicide is higher than that of couples using other metho
A vapor-compression evaporator, like most evaporators, can make reasonably clean water from any water source. In a salt crystallizer, for example, a typical analysis of the resulting condensate shows a typical content of residual salt not higher than 50 ppm or, in terms of electrical conductance , not higher than 10 μS/cm .
It is suspected that The Howard Avenue Water Purification Plant, one of two water treatment plants in Milwaukee at the time, was contaminated. It is believed that the contamination was due to an ineffective filtration process. [1] Approximately 403,000 residents were affected resulting in illness and hospitalization.

The first method utilizes an ejector system motivated by steam at manometric pressure from an external source in order to recycle vapor from the desalination process. The form is designated ejectocompression or thermocompression. Using the second method, water vapor is compressed by means of a mechanical device, electrically driven in most cases.
Station for complex water treatment SKO-10K. One of the first steps in most conventional water purification processes is the addition of chemicals to assist in the removal of particles suspended in water. Particles can be inorganic such as clay and silt or organic such as algae, bacteria, viruses, protozoa and natural organic matter.
