Problems solved by technology

Less conventional techniques, such as ultraviolet (UV) light irradiation or ozone treatment, are effective against viruses and bacteria, but do little to remove other contaminants such as dissolved gases, salts, hydrocarbons, and insoluble solids
Additionally, most distillation techniques, while advantageously removing some contaminants, are often not capable of handling all classes of contaminants

Embodiment 1

[0268] Removal of non-volatile or volatile organic compounds in the degasser

[0269] As a demonstration of the effectiveness of the deaerator in the described embodiment of the invention, a test was performed using isopropanol in input water. The system was energized to achieve full operation of the degasser: the system was warmed up to enable the preheat function and to deliver a steady state volume of steam from the evaporation chamber into the degasser. An input water sample containing 4 ppm isopropanol was directed to the system and the product water from this sample was then quantitatively tested for the presence of isopropanol. A reduction of about 100 times was measured: the concentration of isopropanol in the output water was about 40 ppb.

Embodiment 2

[0271] removal of biological contaminants

[0272] Because total coliforms can be cultured relatively easily in the laboratory, they serve as the primary indicator bacteria for the presence of pathogenic organisms. Coliform bacteria are not pathogenic (disease-causing) organisms, and they are only mildly infectious. For this reason, these bacteria can be handled relatively safely in the laboratory. If large numbers of coliform bacteria are found in the water, it is very likely that other disease-causing bacteria or organisms may be present, such as Giardia and Cryptosporidium. Public drinking water supplies are tested to demonstrate the absence of total coliform bacteria per 100ml of drinking water. Approved tests for total coliform bacteria include membrane filtration, multi-tube fermentation, MPN and MMO-MUG ("Colilert") methods. Membrane filtration methods use microporous filters that retain bacteria. The filters were placed in Petri dishes on mats with growth rich me...

Embodiment 3

[0302] Preparation of Degasser Equipment

[0303] 1” wide x 12” high stainless steel cylinder equipped with stainless steel water inlet and stainless steel air / water outlet, such as Figure 8 (In alternative embodiments, a 1" wide x 8" high, 1.5" wide x 8" high, or 3.5" wide x 12" high device may be used). The unit is attached to the top of the evaporation chamber apparatus. The cylinder was then filled with clean spherical glass beads as follows. The outer zone was filled with glass beads having a diameter of about 8 mm. The middle layer is then filled with beads having a diameter of about 6 mm. The central area is then filled with glass beads having a diameter of about 4 mm. The degasser is equipped with a stainless steel cover unit. The evaporation chamber is heated and steam is passed through a degasser. As the degasser heats up, the water to be treated is preheated and then added to the top of the degasser. The water leaving the deaerator will have reduced amount...

Abstract

Embodiments of the invention provide systems and methods for water purification. The systems have a preheater (30), a degasser (40), an evaporation chamber (50), a demister (70), and a control system (120), wherein the control system (120) permits operation of the purification system (10) through repeated cycles without requiring user intervention or cleaning. The system is capable of removing, from a contaminated water sample, a plurality of contaminant types including: microbiological contaminants, radiological contaminants, metals, salts, volatile organics, and non-volatile organics.

Description

technical field [0001] The present invention relates to the field of water purification. In particular, embodiments of the present invention relate to systems and methods for removing substantially all of the various impurities from water in an automated process that does not require cleaning or user intervention over the course of months to years, per unit Input water has a relatively high yield of product water. Background technique [0002] With conventional water resources becoming increasingly scarce, municipal distribution systems for drinking water deteriorating over time, and increased water use depleting wells and reservoirs, causing saltwater contamination, water purification technologies are rapidly becoming a necessary aspect of modern life. In addition, other water sources are polluted by various activities including, for example, intensive agriculture, gasoline additives, and toxic heavy metals. These problems lead to increased and unacceptable levels of germ...
