An expansion tank for at least temporarily storing a pumped liquid under pressure, the including a thin wailed outer shell and a diaphragm located internally of the tank, and sealingly secured to the inner surface of the shell of the tank to divide the internal volume of the tank into a fluid-tight section for holding a gas under pressure and a fluid-tight section for holding a liquid under pressure. The diaphragm has an enlarged lip around the outer circumference of the diaphragm and being is connected to the interior portion of one of the substantially cylindrical sections via the enlarged lip being fitted tightly into a coupling ring, which in turn presses the enlarged lip of the diaphragm sealingly, circumferentially against the inner circumferential surface of the tank wall when the outer circumferential surface of the coupling ring is sealingly connect to the inner wall surface of one of the tank segments, sealing the enlarged lip against the inner surface of the tank. The tank segments are not finally assembled until after the diaphragm is sealed against the tank wall, so that the diaphragm divides the interior volume of the tank into two mutually fluid tight volumes that can be rendered fluid tight with respect to the space outside of the tank walls.

A water storage tank with passive enhanced thermal energy management is provided. The tank is formed of substantially cylindrical central section comprising a majority of the length along its axis and a dome-shaped section at each end, A first system of managing energy management includes providing insulation covering all or most of the tank in order to prevent heat flow energy leaving the tank. The strength of the insulation, is varied such that one end of the tank has less insulativity than the other end of the tank. Preferably change occurs gradually along the axial length of the tank. The second system for providing passive energy management is using insulation formed of a material that has a glass phase change temperature at or near the temperature of the water when it enters the tank. In order for the temperature of the water in the tank to change from the initial temperature it must first cause the insulation to make that glass phase change in order to either heat up or cool down from its initial temperature point. By varying the mass or thickness of the glass phase insulation along the axial length of the tank the amount of passive energy resistance to change varies thereby causing desired convection currents that serve to maintain a constant temperature within the tank thereby slowing any change of temperature at minimum cost.

EXPANSION TANK WITH DECOUPLED SINGLE FLEXIBLE DIAPHRAGM
An expansion tank with an improved diaphragm seal includes a seal for the joint between the flexible diaphragm and either an optional. non-flexible diaphragm or the tank wall, the providing of a seal support that prevents collapse, delamination, or tearing of the 5 tank shell wall. The tank shell may be formed of two substantially hemispherical domes joined together, either directly or at the two ends of a substantially cylindrical section. One of the segments forming the shell of the expansion tank, further comprises an extension lip, extending inwardly of the tank and around the entire circumference of the inner surface of the shell wall, located substantially near the junction of two of the sections 10 forming the tank. This extension lip may be made from the same material as the tank wall, or may be part of a separate circumferential connector interconnecting two of the sections of the tank wall.

An improved expansion tank is provided for at least temporarily storing a pumped liquid under pressure, the expansion tank comprising a thin walled outer shell formed of two substantially hemispherical domes joined together, either directly or at the two ends of a central, substantially cylindrical section, and a flexible diaphragm located internally of the tank and secured to the inner surface of the shell of the tank to divide the internal volume of the tank into a fluid-tight section holding a gas under pressure and a fluid-tight section for holding an aqueous liquid under pressure. The improvement comprising diaphragm coupling ring formed as a discrete part of the diaphragm tank that can be fabricated independent of the domes and any cylinder. The diaphragm coupling ring provides a robust, leak-proof seal with the diaphragm, so that it can be connected onto an inner surface of an expansion tank in a separate, secondary operation.

Through wall connector for a multi-chamber pressure vessel
A gas and liquid-tight inlet connector to the inner chamber of a mufti-chamber pressure vessel is provided, comprising: a male gland extending through an orifice in the bottom of the flexible wall of the inner chamber and the lower wall of the rigid outer shell of the vessel, the male gland comprising an upper flange permanently, sealingly connected, with the lower surface of the flexible inner wall, so as to form a gas- and liquid-tight seal therewith, and a lower elongated member extending through the outer shell to be sealingly connected with a liquid inlet pipe, permitting liquid flow into the inner chamber, while maintaining the seal between the inner and outer chambers of the tank, thus maintaining pressurization in the outer chamber, as fluid enters the inner chamber, pushing the flexible wall upwardly into the outer chamber.

A water purification system for continuously disinfecting water in a holding tank that provides uniform mixing and increased residence time. The system comprises a double disinfectant tank for potable water, comprising an inner tank and an outer tank. The inner tank being located wholly within and in the lower portion of the outer tank. The water and disinfectant inlet feeds water directly into the inner tank through a tube extending into the inner tank. The inner tank is sealed off from the outer tank except for limited openings located primarily in the lower half of the inner tank wall. The inlet tube preferably extends at least about 50% of the height of the inner tank, to a point above the location of the limited openings in the lower half of the inner tank. This results in better mixing, especially when the flow through the limited openings is high enough to create turbulent flow, and greater residence time compared to baffled tanks.
