Desalination

Water Desalination Purification

Mechanical Oscillation

A new water purifying and seawater desalting technology is based on a hydro-wave method, which has never being used in this area of activity before. Physical processes based on hydrodynamic modes created in an aquatic environment in combination with the exposure of the electromagnetic fields, make favorable conditions in a purifying solution for water evaporation many times faster than in any other known cases.

For the first time in the world practice, the purification and desalting of the aquatic environments from the suspended particles and soluble substances are being carried out only due to hydrodynamic effects with the influence on the water by sources of the mechanical oscillation.

Application

Our Competitive Edge

How Does it Work

Raw water goes into the Circulation Make-up Tank (CMT) designed to adjust required pressure necessary for further operation of the system and maintain the necessary amount of source water and for recirculation and flotation of water. If it is required, a dirt filter will be installed before CMT to avoid getting into process pumps large solids.
Process pumps supplies the cleaning water in the Hydrodynamic Generator. Ejectors inside of the Hydrody-namic Generator highly saturate water with oxygen from the air. In addition, HDG creates the necessary conditions for the formation of cavitation (water is supplied with a rated flow speed and pressure). Cavitation appears because of local reduction of pressure in the fluid by increasing its speed (hydrodynamic cavitation).
When the local fluid pressure at a certain point falls below the value corresponding to the saturated vapour pressure at a given ambient temperature, the liquid passes into another aggregate state to form primarily the phase voids called cavitation bubbles. Cavitation physical process similar to the process of boiling liquid. 

The main difference between them lies in the fact that  the boiling liquid phase change occurs at an average of the volume of fluid pressures are equal to the saturated vapour pressure, whereas the average cavitation fluid pressure above the saturated vapour pressure and the pressure drop is local. Due to the effect makes insolubilization of most of dissolved substances in the initial water and partially disinfects it. In addition, due to the abundant oxygen saturation metals contained in the 

water (i.e. iron, manganese etc.) are oxidized followed by coagulation of water impurities (the process of enlargement of tiny colloidal and dispersed particles because of their mutual agglutination by molecular attraction forces).

Water from HDG goes to the divider that performs a partial de-aeration (i.e. removal of excess air) and return the rated volume of treated water in the CMT, to provide flotation and the beginning of oxidation and coagulation in the crude water. 

The main flow of water from the divider goes to Coagulator. Coagulator is a reservoir with a number of technological barriers and overflows where coagulation is completed by aggregation flakes, and separating them from the liquid.

Coagulator must not be backwashed systematically except in cases of maintenance and repair works) that provides a much more rapid sedimentation of smallest colloidal particles in the flakes contained inside of Coagulator to reduce the time of the coagulation process and to increase efficiency of water purification. Water from Coagulator goes into the Sediments Collector that is decolouring filter with bed of quartz sand of various fractions. Water goes from bottom to top that traps flakes generated in Coagulator due to gravity and chocking particles in the bed gaps. More than that the effectiveness of particle settling increases as the filling of spaces between particles of the bed because this provides finer trap small dispersed and colloidal particles that has not reached the required size during coagulation By filling Sediments Collector are backwashed with clean water.

Washing frequency may be estimated by weight, knowing the content of impurities in water and purified water after cleaning, but by also using instruments by setting the critical level of pressure reduction at the wa-
ter outlet of the Sediments Collector as compared with the inlet pressure.

Water from Sediments Collector goes to the Collecting Tank and further to the consumer. 

In fact that water has high grade of differences for various locations and requirements for purified water are changing for diverse purposes it is hard to achieve all goals with one systems. That is why the ENERVOXA system was designed flexible in mind with ability to extend it depends on customer requirements. 

In example, depending on the length of water pipe network, its technical and sanitary conditions the water must be decontaminated by any well-known method (UV, chlorination, fluorination or others).

Seawater desalination is requiring setting up fine treatment stage based on reverse osmosis technology. In that case, CAVITECATM system reduces the Total Dissolved Solids up to 40%-60%. This is by far simplify operational conditions of reverse osmosis and dramatically reduce consumption of power and materials by its. The estimated savings with use of CAVITECATM system is about 3 times lower to compare with standard installation of reverse osmosis.
