Distributor assembly for pressure vessel and method of installation
The invention provides a fluid distributor and associated water treatment system. The system includes a pressure vessel adapted and configured to hold a predetermined volume of fluid and a fluid distribution assembly. The fluid distribution assembly is preferably disposed at a lower end of the pressure vessel, and includes a water inlet manifold adapted and configured to direct water from an upstream location into a vessel that the distributor assembly is mounted into, a water outlet manifold adapted and configured to direct water from the vessel to a downstream location and an air volume control valve adapted and configured to maintain a predetermined pressure range in the vessel.
1 . A fluid distributor assembly for a pressure vessel, comprising:
a) a water inlet manifold adapted and configured to direct water from an upstream location into a vessel into which the distributor assembly is mounted;
b) a water outlet manifold adapted and configured to direct water from the vessel to a downstream location; and
c) an air volume control valve adapted and configured to maintain a predetermined pressure range in the vessel.
2 . The fluid distributor assembly of claim 1 , wherein the distributor assembly is adapted and configured to be mounted through the bottom of a pressure vessel.
3 . The fluid distributor assembly of claim 1 , wherein the air volume control valve includes a vent line adapted and configured to direct vented air from the air volume control assembly out through the distributor.
4 . The fluid distributor assembly of claim 1 , wherein the water outlet manifold includes a first output for directing potable water to a first downstream location.
5 . The fluid distributor assembly of claim 4 , further comprising a drain line in fluid communication with the water outlet manifold.
6 . The fluid distributor assembly of claim 1 , wherein the water inlet manifold includes an output line for directing untreated water to an irrigation system.
7 . The fluid distributor assembly of claim 1 , wherein the air volume control assembly is adapted and configured to control the water level in the tank.
8 . The fluid distributor assembly of claim 7 , wherein the air volume control assembly is adapted and configured to control the water level in the tank between a low level setpoint and a high level setpoint.
9 . A water treatment system, comprising:
a) a pressure vessel adapted and configured to hold a predetermined volume of fluid; and
b) a fluid distribution assembly disposed at a lower end of the pressure vessel, the fluid distribution assembly including:
i) a water inlet manifold adapted and configured to direct water from an upstream location into a vessel that the distributor assembly is mounted into;
ii) a water outlet manifold adapted and configured to direct water from the vessel to a downstream location; and
iii) an air volume control valve adapted and configured to maintain a predetermined pressure range in the vessel.
10 . The system of claim 9 , wherein the pressure vessel includes a plastic tank with a reinforcing layer disposed about the periphery of the plastic tank.
11 . The system of claim 9 , further comprising a pump upstream of and in fluid communication with the water inlet manifold, the pump being adapted and configured to pressurize a feed water stream delivered to the water inlet manifold.
12 . The system of claim 11 , further comprising an air inductor upstream of and in fluid communication with the water inlet manifold and downstream of and in fluid communication with the pump, the air inductor being adapted and configured to entrain air into water passing through the inductor.
13 . The system of claim 9 , wherein the air volume control valve includes a vent line adapted and configured to direct vented air from the air volume control assembly out of the vessel through the distributor.
14 . The system of claim 9 , wherein the water outlet manifold includes a first output for directing potable water to a first downstream location.
15 . The system of claim 14 , further comprising a drain line in fluid communication with the water outlet manifold.
16 . The system of claim 9 , wherein the water inlet manifold includes an output line for directing untreated water to an irrigation system.
17 . The system of claim 9 , wherein the air volume control assembly is adapted and configured to control the water level in the tank.
18 . The system of claim 17 , wherein the air volume control assembly is adapted and configured to control the water level in the tank between a low level setpoint and a high level setpoint.
19 . A method of treating a fluid stream in a pressure vessel, comprising:
a) introducing water into the pressure vessel by way of a water inlet manifold;
b) evacuating treated water from the pressure through a water outlet manifold; and
c) maintaining a predetermined pressure range in the vessel using an air volume control valve, wherein all fluids are directed into and out of the pressure vessel through the bottom of the pressure vessel.
