Abstract
A method and a system are described that seamlessly integrate a recycled water treatment system with a water supply system from a water well to supply low salinity fresh water to be used by a petroleum processing facility. The control scheme allows for the recycled water treatment system as a primary source to supply water for process, utilities and other needs while ensuring no interruption in supply. This is achieved by integrating it through a control scheme to supply water from the water well as a supplemental source in case of disruption due to outage of the recycled water treatment system.
Claims20
A method to supply fresh water, comprising:
- coupling a primary water source and a water storage tank, wherein the primary water source comprises a recycled water treatment system;
- coupling a supplemental water source and the water storage tank, wherein the supplemental water source comprises a water well;
- detecting that a level of stored water in the water storage tank being less than a normal level to generate a first result;
- in response to the first result, initiating treated fresh water to flow from the recycled water treatment system into the water storage tank to replenish the stored water, wherein the water storage tank supplies the stored water to a processing facility;
- detecting that a flow rate of the treated fresh water from the recycled water treatment system being disrupted to below a minimum usable flow rate to generate a second result;
- in response to the second result, shutting off the treated fresh water from the recycled water treatment system into the water storage tank;
- detecting that the level of the stored water in the water storage tank being reduced to below a minimum acceptable water storage level to generate a third result;
- and
- in response to the third result, initiating produced fresh water to flow from the water well into the water storage tank to further replenish the stored water, wherein the water storage tank continues to supply the stored water to the processing facility,
- wherein the primary water source and the supplemental water source collectively maintain uninterrupted water supply to the processing facility.

A water supply control system to supply fresh water, comprising:
- a primary water supply line that couples a primary water source and a water storage tank, wherein the primary water source comprises a recycled water treatment system;
- a primary water source controller that controls the primary water supply line;
- a supplemental water supply line that couples a supplemental water source and the water storage tank, wherein the supplemental water source comprises a water well;
- a supplemental water supply line controller that controls the supplemental water supply line;
- and
- the water storage tank that stores the fresh water for supplying to a processing facility,
- wherein the primary water source controller comprises:
- a water level sensor that detects a level of stored water in the water storage tank being less than a normal level to generate a first result;
- a first flow control valve inserted in the primary water supply line that, in response to the first result, opens for treated fresh water to flow from the recycled water treatment system into the water storage tank to replenish the stored water;
- and
- a flow rate controller that detects a flow rate of the treated fresh water from the recycled water treatment system being disrupted to below a minimum usable flow rate to generate a second result,
- wherein the first flow control valve, in response to the second result, shuts off the treated fresh water from the recycled water treatment system into the water storage tank, and
- wherein the water level sensor further detects that the level of the stored water in the water storage tank being reduced to below a minimum acceptable water storage level to generate a third result,
- wherein, in response to the third result, the supplemental water supply line controller initiates produced fresh water to flow from the water well into the water storage tank to further replenish the stored water, and
- wherein the primary water source and the supplemental water source collectively maintain uninterrupted water supply to the processing facility.
