A system for desalinating water is disclosed. The system comprises a subsea reverse osmosis unit located beneath the surface of a body of water, a first liquid column comprising seawater, a second liquid column comprising desalinated water with a salinity less than seawater, and a brine discharge outlet. Due to the difference in density between the seawater and the desalinated water, the gravitational hydrostatic pressure of the first liquid column may be greater than the gravitational hydrostatic pressure of the second liquid column. At least a portion of the pressure difference for reverse osmosis desalination may be provided by the difference in gravitational hydrostatic pressure between the first liquid column and the second liquid column. A significant reduction in desalination energy consumption may be enabled by discharging the brine at an elevation lower than the maximum elevation of the first liquid column or the second liquid column.

A water monitoring device monitors and maintains swimming pool chemistry. The device mixes reagents with water in flowcells. The water chemistry is detected by measuring the light transmitted through the flowcells. The water monitoring device can communicate with computers, servers and mobile computing devices which can store and display the water chemistry information. The reagents can be stored in a replaceable reagent cartridge which can provide reagents for water testing and can be replaced when the reagents need to be replenished.

Also described is a water monitoring apparatus and a method of monitoring a body of water.

A large scale water desalination process for producing at least 100,000 m.sup.3/day of product water. Feed water is passed through a high pressure pump driven by at least one steam turbine capable of producing at least 1 MW of energy, the pressurized feed water passing through at least one reverse osmosis membrane to provide a residual brine stream and a product water. A start-up step slowly increases pressure in the membrane at a maximum rate of 12 psi (8.3 Newtons/cm.sup.2; 0.08 MPa) per second by rotation of the turbine driven high pressure pump at a maximum rate of 30 RPM to slowly increase pressure on the membrane to a predetermined operational pressure and controlling the operational pressure following the start-up step by rotation of the high pressure pump between 500 RPM and 5000 RPM dependent on the pressure applied by the steam turbine.

The invention relates to an electromagnetic wave irradiation reactor (fixed, mobile or portable) suitable for the physical, dynamic, continuous conditioning of materials having the ability to absorb electromagnetic radiation, which need to be treated through electromagnetic irradiation, without coming into contact with the electromagnetic source. In particular, this invention aims to treat those materials which tend to reflect such radiations, which are translucent or difficult to penetrate to irradiation or simply dirty. The invention mainly exploits the postulates of Lambert, and Stefan-Boltzmann, that is, the physical assumptions of the transmission of electromagnetic energy by radiation and in particular the angle, concentration and proximity of the emission of energy between emitter and receiver (which varies with the square of the distance) and the intensity of the emission (which varies with the 4th power of the temperature).

The present invention relates to a handheld electronic soap device (1), where pH neutral water is poured in the device through a water inlet (2) into an electrolytic cell (11). The pH neutral water is split into acidic ionized and alkaline ionized water by an electrolysis. The alkaline and acidic water can be used for cleaning and rinsing of skin or hair. More particularly, the alkaline water enables to clean skin or hair, whereas the acid water is important to maintain the acid environment on hairs and skin. According to the present invention a user can select between acidic or alkaline water to be poured out of the device through a water outlet (4).
