Embodiment 1

[0177] Removal of non-volatile or volatile organics in degassers

[0178] As a demonstration of the effectiveness of the deaerator in the described embodiment of the invention, a test was performed with isopropanol in incoming water. Allow the system to charge for full deaerator functionality: warm up the system to allow preheating and a steady state volume of steam is delivered from the evaporation chamber to the deaerator. A sample of incoming water containing 4 ppm isopropanol was introduced into the system, and the product water from the sample was then quantitatively tested for the presence of isopropanol. A decrease of about 100× was noted: the concentration of isopropanol in the effluent was about 40 ppb.

Embodiment 2

[0180] Removal of Biological Contaminants

[0181] Total coliforms are relatively easy to culture in the laboratory and, therefore, have been chosen as the primary indicator bacteria for the presence of disease-causing microorganisms. Coliform bacteria are not pathogenic (disease-causing) microorganisms and are only weakly infectious. For this reason, these bacteria are relatively safe to work in experiments. If large amounts of coliform bacteria are found in the water, there is a high likelihood that other pathogenic bacteria or microorganisms such as Giardia and Cryptosporidium may be present. Public drinking water is tested to demonstrate the absence of total coliform bacteria per 100ml of drinking water. Accepted tests for total coliform bacteria include membrane filtration, multi-tube fermentation, MPN and MMO-MUG ("Colilert") methods. Membrane filtration methods use microporous filters that trap bacteria. Filters were placed in petri dishes on mats with growth enrich...

Embodiment 3

[0211] Preparation of the degasser apparatus

[0212] As shown in Figure 8, a 1" wide by 12" high stainless steel cylinder was fitted with a stainless steel water inlet and stainless steel air / water outlet (in an alternative embodiment, a 1" wide by 8" high, 1.5" wide by 8" high or 3.5" wide by 12" high devices). Attach the unit to the top of the evaporation chamber assembly. Then, the cylinder was filled with clean spherical glass beads as follows. The outer area is filled with glass beads with a diameter of about 8 mm. The middle layer is then filled with beads with a diameter of about 6 mm. Then, the central area was filled with glass beads with a diameter of about 4 mm. The degasser is fitted with a stainless steel cover unit. The evaporation chamber is heated and steam is allowed to pass through the degasser. Once the deaerator is warm, the water to be treated is preheated and added to the top of the deaerator. The water leaving the deaerator will have reduced amou...

Abstract

Devices and methods for water purification are provided. An improved demister for removing liquid or other particles from steam is disclosed. The demister can have adjustable outlets. In other embodiments, a demister apparatus is placed, at least partially, inside a boiler apparatus. Additionally, a filter flow indicator that provides an optical indication of the efficiency of a water filter is also provided. The filter flow indicator has a viewable side passage that connects the input and output sides of a filter unit. A weighted object, such as a ball, can move up and down the side passage in response to the pressure differential in the filter system. The user can determine the status of the filter by viewing the location of the weighted object in the side passage. Additionally, a device and method of adding various minerals back to purified water in order to improve the flavor of the water is described. The device and method involve the use of a ground mineral mixture, typically chosen from minerals that are common in natural springs. Pure water that runs through the mineral filter apparatus can take up some of the minerals, thus creating water that, although free from unhealthy contaminants, tastes like natural spring water.

Description

[0001] related application [0002] This application claims priority under 35 U.S.C. § 119(e) to the following U.S. provisional applications: 60 / 697,104 filed July 6, 2005; 60 / 697,106 filed July 6, 2005; 60 / 697,107 filed March 3, 2006; 60 / 779,201 filed March 3, 2006; 60 / 727,106 filed October 14, 2005; and December 7, 2005 60 / 748,496, each of which is incorporated by reference in its entirety. field of invention [0003] This application relates to the field of water purification. Background of the invention [0004] Water purification technologies are rapidly becoming an essential aspect of modern life as traditional water sources become increasingly scarce, municipal distribution systems for drinking water deteriorate with age, and increased water usage depletes wells and reservoirs, thereby lead to salt water contamination. In addition, further contamination of water sources is occurring by various activities including, for example, intensive agriculture, gasoline addit...
