A new and innovative power and treated water co-generation system is provided that includes a modified Kalina cycle and a forward osmosis (FO) membrane. The Kalina cycle of the provided system is used for power production, whereas the system's FO process is used for water production. The provided system modifies a typical Kalina cycle to include a more efficient and relatively low-temperature heat source, while still utilizing the same working fluid, which is ammonia-water. The draw solution for the provided system's FO process is also ammonia-water, which is known and efficient for desalination and wastewater treatment. In some aspects, the working fluid of the system may be a specific ammonia-water composition including between 30-95% ammonia. The presently disclosed system combines the Kalina process and the FO process into an improved and innovative heat integration system to minimize energy requirements and enable operation at both small and large scales.

A liquid purification system with purified water mineralization, which uses predominantly water from various resources. The main problem of existing liquid purification systems, particularly membrane systems, is that during purification process not only dangerous debris (residual oil, pesticides, herbicides, heavy metals, bacteria, viruses, mechanical particles and other) are removed, but even minerals necessary for human (calcium, potassium, magnesium, sodium and other), so mineralization step is needed after purification step to normalize mineral composition. In the state of the art are known liquid purification systems with integral mineralization means and also devices for mineralization, which can be connected to liquid purification systems. The working principle of systems, known in the state of the art, is that purified liquid flows through the vessel with mineralization additive, which is partly dissolved, and the liquid becomes mineralized. The main drawback of the systems known in the state of the art is that due to peculiarities of the dissolving process and/or mineralization additive content it is impossible to control mineralization process, so the mineralization level is minor, and the pH is higher than the permitted value. Liquid purification system containing raw liquid line, liquid purification unit, mineralization unit, purified liquid line is characterized in that, mineralization of liquid is done by controlled dispensing of mineralization solution, obtained by selective raw or drainage liquids or their mixture.

The system includes a tank configured to receive permeate from the downstream side of the membrane and to store a standby volume of the permeate for delivery to the outlet during an initial portion of a water draw, and a control system for manipulating the plurality of valves.

The invention relates to a method for filtering water comprising the use of a pump (14) to supply a filtering means (17), said supply being performed by simultaneous suction, for example by the same pump (14), through an ultrafiltration module (12).

An exemplary power system utilizes turbines configured within a water intake conduit to the desalination processor to produce power for the desalination processor. Water intakes are configured to provide a natural flow of water to the desalination processor though hydrostatic pressure. One or more turbines coupled with the water intake conduits are driven and produce power for the system. The desalination processor incorporates Graphene filters to and may include a structured water system to increase the H3O2 concentration of the water prior to Graphene filters. Discharge water may be pumped back into the body of water but be separated from the intakes. A secondary power source, such as a renewable power source, may be used to produce supplemental power for the system. Power produced may be provided to a secondary outlet, such as a power grid, all above and/or underground.
