  • Publication number: 20150013986
    Abstract: A method of hydraulic fracturing of an oil producing formation includes the provision of a heating apparatus which is transportable and that has a vessel for containing water. The method contemplates heating the water up to a temperature of about 200° F. (93.3° C.). A water stream of cool or cold water is transmitted from a source to a mixer, the cool water stream being at ambient temperature. The mixer has an inlet that receives cool or cold water from the source and an outlet that enables a discharge of a mix of cool or cold water and the hot water. After mixing in the mixer, the water assumes a temperature that is suitable for mixing with chemicals that are used in the fracturing process, such as a temperature of about 40°-120° F.+ (4.4-48.9° C.+). An outlet discharges a mix of the cool and hot water to surge tanks or to mixing tanks. In the mixing tanks, a proppant and an optional selected chemical or chemicals are added to the water which has been warmed.

This accumulate may be adjustably admixed into the waste products of a household drinking water purification system, thereby diluting it to acceptable levels that may be useful for washing and the like. Additionally, and/or alternatively, the fresh water stream may be admixed into the water purification waste water stream. Each of these water conserving functions is conformed to be combined in a stepwise manner, thereby accommodating budgetary and use growth constraints.

  • Patent number: 8245946
    Abstract: A unitary valve block assembly is interposed between a hot and cold water outlet and a faucet assembly including a hot and cold valve to convey the initially cold portion from the hot water outlet into an accumulator during all the times when the accumulator is substantially unfilled. This accumulated water is then emitted through the cold water valve each time cold water is demanded. When the pressure ratio between the accumulator and the water source indicates that it contains substantial quantities of un-evacuated stored water the subsequent demands of hot water are conveyed directly to the hot water valve regardless of the temperature thereof.

  • Publication number: 20120061483
    Abstract: Disclosed herein is a hot/cold water supply system with an improved control part. Cold water that has remained in a pipe is re-circulated through a circulating water pipe and is re-supplied into and heated by a boiler rather than being discharged out of a faucet, and the temperature of the water is adjusted in a thermo-and-geared valve to a temperature preset by a user so that water with a low temperature deviation can be supplied to the user. Further, an excessive load is prevented from being applied to the thermo-and-geared valve. Water of different temperatures preset by users can be supplied to corresponding control zones. A sudden deviation in temperature can be prevented when the boiler re-ignites. When the temperature of water reaches a preset temperature, a control panel indicates it to the user on a display and/or by providing a sound, thus making it more convenient to use.

    Abstract: A separated-flow temperature control faucet mainly comprises a constant temperature control device to mix hot water and cold water, a flow divider valve to control water flow direction and a main housing coupling with the constant temperature control device and the flow divider valve. The constant temperature control device contains an axial movement member movable axially by turning to control hot and cold water flow amount to control water temperature. The flow divider valve provides water separating function and stop function to stop water from flowing out. The faucet thus formed has a longer life span, is less likely to accumulate water dreg, can supply a greater water discharge amount, stabilize water temperature, and offer a simpler structure and improve usability.
