Electrodeionization (EDI) is a water treatment technology that utilizes DC power, ion exchange membranes, and ion exchange resin to deionize water.EDI is typically employed as a polishing treatment following reverse osmosis (RO), and is used in the production of ultrapure water.
Imhoff tank. a - upper chamber, b-c - outlet for sludge, d - outlet for biogas (would need to be higher), f - lower chamber, g - slot for sludge to pass from the upper to the lower chamber, h - height. The Imhoff tank, named for German engineer Karl Imhoff (1876–1965), is a chamber suitable for the reception and processing of sewage.
The clarified water is then fed through a high-pressure piston pump into a series of RO vessels. 90.00–99.98% of the raw water's total dissolved solids are removed and military standards require that the result have no more than 1000–1500 parts per million by measure of electrical conductivity. It is then disinfected with chlorine.
The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...
Ozzy & Drix is an American animated television series based on the 2001 film Osmosis Jones.It centers on Osmosis "Ozzy" Jones, a cheeky-chappy white blood cell, and Drix, a level-headed cold pill, who battle germs and viruses inside the body of teenage boy Hector Cruz.
In normal potable water production without the requirement of high recoveries, reverse osmosis is generally believed to be more cost-effective when total dissolved solids (TDS) are 3,000 parts per million (ppm) or greater, while electrodialysis is more cost-effective for TDS feed concentrations less than 3,000 ppm or when high recoveries of the ...
Ozzmosis is the seventh studio album by English heavy metal singer Ozzy Osbourne.Recorded in Paris and New York with producer Michael Beinhorn, it was released on 23 October 1995 by Epic Records.
Reverse osmosis plants require a variety of pre-treatment techniques including softening, dechlorination, and anti-scalent treatment. [3] Following pre-treatment, high levels of pressure send water through a semi-permeable membrane, which retains all contaminants but lets pure water pass through. [4]
