Abstract
Abstract An apparatus is provided between a contaminated water source and a potable water supply which renders effective chemical purification of the water while providing a means of controlling the water input to the apparatus in accordance with the demand for potable water. The controlling means is operated by a pressure chamber which is in turn regulated by a pressure relief means. A relatively small amount of water is chemically treated and subsequently mixed with a large quantity of untreated water.

In an apparatus for rendering contaminated water potable which comprises a water source, a flow controlling means for controlling the flow of water from the water source, a chemical purification means, a first conduit connecting the flow controlling means to the purification means, and an outlet from the purification means to a potable water supply; the improvements which comprise providing the water source with a filtration means capable of removing particles larger than about 300 microns from the water entering the flow controlling means, and wherein the flow controlling means is responsive to the level of the potable water supply and which comprises (a) a valve coupled with the water source and (b) an activating means for opening and closing the valve which comprises (i) a variable hydrostatic pressure chamber communicating with the valve whereby the valve is in the open position when the pressure in the chamber is less than the hydrostatic pressure of the water source, (ii) a pressure relief means communicating with the variable hydrostatic pressure chamber and a water overflow chamber such that when the leVel of the potable water supply reaches a predetermine minimum, the relief means operates to reduce the hydrostatic pressure in the pressure chamber by permitting water to flow from the pressure chamber into the overflow chamber, (iii) a second conduit from the water source to the pressure chamber and which bypasses the valve whereby water is introduced into the pressure chamber until the hydrostatic pressure of the pressure chamber is about equal to the hydrostatic pressure of the water source, and (iv) a third conduit communicating between the overflow chamber and the chemical purification means whereby water entering the overflow chamber is conveyed to the chemical purification means.
Claim 3
Dependent Claim
133 words
The improvement of claim 1 in which the chemical purification means comprises (a) housing having an upper horizontal chamber and a lower horizontal chamber, the upper chamber communicating with the first conduit and with the outlet to the potable water supply, and the lower chamber communicating with the (i) upper chamber by means of a fourth conduit from the lower chamber to the upper chamber such that a portion of the water entering the upper chamber flows through the fourth conduit into the lower chamber, the fourth conduit being provided with a valve means to regulate the quantity of water which flows therethrough and (ii) with the outlet to the potable water supply; and (b) a chemical source communicating with the lower chamber for introducing chemicals into the water in the lower chamber.
Claim 4
Dependent Claim
165 words
The improvement of claim 2 in which the pressure relief means is operated by an adjustable rod and float assembly which comprises (i) a float having a specific gravity of less than unity, (ii) a first rod having one end substantially fixed to the float and the other end substantially fixed to a first pivoting clamp, (iii) a second rod having one end substantially fixed to the first pivoting clamp such that the angle formed by the first rod and second rod and having its vertex at the first clamp can be adjusted to conform to the water level of the potable water supply, and the other end of the second rod substantially fixed to a second pivoting clamp; and (iv) a pressure relief means operating arm projecting from the second clamp and pivotably fixed at its end to the apparatus, and the operating arm contacting the pressure relief means at a point on the arm between its pivoting fixed end and the second clamp.
Claim 5
Dependent Claim
24 words
The improvement in claim 2 in which the chemical source comprises a solid, water soluble, water purifying chemical in the form of compressed pellets.
Claim 6
Dependent Claim
161 words
The improvement in claim 2 in which the chemical source comprises: a. an open-ended cylindrical wall passing vertically from the outside of the housing through the upper chamber in a sealed relationship therewith into the lower chamber; b. a hopper for holding a particulate solid to be dissolved by the water in the lower chamber, the hopper passing axially through the cylindrical wall and communicating with the lower chamber, and having a closed upper end and a foraminous lower end; c. an adapter means for holding the hopper in an adjustable relationship with the cylindrical wall such that the position of the lower foraminous end of the hopper can be adjusted, relative to the lower chamber whereby the rate of dissolution of the particulate solid can be accurately controlled; and d. a damming means in the lower chamber adjacent the outlet to maintain a level of water in the lower chamber within the proximity of the lower end of the hopper.
Claim 7
Dependent Claim
115 words
The improvement in claim 1 in which the valve is a flexible diaphragm one side of which communicates with the water source the other side of which communicates with the variable hydrostatic pressure chamber such that when the hydrostatic pressure of the water source and the hydrostatic pressure in the chamber are substantially equal said diaphragm is in a closed position abutting the water source thereby precluding the flow of water from the water source and when the hydrosTatic pressure of the water source is greater than the hydrostatic pressure in the chamber said diaphragm moves into an open position away from the water source, thereby allowing the flow of water from the water source.
Claim 8
Dependent Claim
43 words
The improvement of claim 5 in which the lower chamber is provided with a weep hole which communicates between the lower chamber and the outlet, thereby permitting the water level in the lower chamber to subside when the apparatus is not in use.
Claim 9
Dependent Claim
83 words
The improvement of claim 2 in which the fourth conduit communicates with (a) the upper chamber at a position below the normal water level of the upper chamber when water is flowing through the apparatus, and (b) with the lower chamber at a position below the water level of the lower chamber and substantially perpendicular to the flow of water through the lower chamber thereby creating a swirling movement in the water in the lower chamber to assure a constant chemical dissolution rate.
Claim 10
Dependent Claim
67 words
The improvement of claim 2 in which the third conduit communicates with the overflow chamber and the lower horizontal chamber, thereby permitting water to flow from chamber, the third conduit being positioned below the water level of the lower chamber and substantially perpendicular to the flow of water through the lower chamber, thereby creating a swirling movement in the water to assure a constant chemical dissolution rate.
