Water Purification System WPS iSAV

The Infinity SAV engineers have developed an innovative device for seawater desalination. The device is able to work completely autonomously and does not require a constant source of external power.
This innovative system is used for desalination, distillation and thorough water purification to the required parameters from most types of contamination and consists of various types of membranes, including reverse osmosis filter, nano filtration units, ultrafiltration systems and the UV decontaminator.
The device of reverse is reliable and easy to operate, it uses standardized components and consumables.
A rechargeable battery is required for the initial start-up; after the start-up, the device recharges itself for permanent operation.
The current in the system is generated by the electrolysis system, which consists of 20 special tanks with salt concentrate, in which the electrode cells are located. This system is capable of generating 2-2.5 kW / h of electricity, which is enough to power the device.
Reverse osmosis is the best known filtration method.
The use of a reverse osmosis system allows you to purify seawater from salts to 97-99.7% pureness. The operation of the reverse osmosis system WPS iSAV provides a high level of water purification, improves the color, taste and properties of the liquid. The WPS iSAV reverse osmosis system is superior to devices that use traditional methods of cleaning and filtering contamination particles, as well as devices that adsorb substances with activated carbon.
The most important part of the system is the software that controls all work processes and monitors the correct operation as well as indicates system failures.

Purification process

The water purification system consists of five series-connected filters and provides a five-step water purification at the molecular level. In the process of cleaning water passes through several stages: mechanical purification, reverse osmosis, disinfection, and mineralization.

Stage I

Mechanical purification

The first stage of purification carries the greatest responsibility. First, water to be cleaned is pumped to the system pre-filter and is preliminarily cleaned of large mechanical impurities.
Mechanical purification is designed to remove various coarse particles of dirt from water (sand, scale, rust, clay, sludge) that can damage all subsequent cleaning elements and reverse osmosis membranes or clog them. For this, two mechanical pre-filters are used in special housings. The filtering substance of the pre-filter is a foamed polypropylene with a fiber density of 5 μm.

Stage II

Reverse osmosis membranes

Then, using the pump, which is part of the system, water is supplied to the reverse osmosis membranes.
The purification process consists in increasing the water pressure level to 100 bar in the system and filtering water through a special polymer thin layer of reverse osmosis membrane filter material with a pore size of 0.0001 μm, which allows only purified and desalted water (permeate) molecules to pass through. Due to a special membrane made of film composite material, the system is capable of removing up to 97% of substances dissolved in water and 98% of organic compounds.
As a result, impurities accumulate on one side of the filter membrane, and on the other, purified water is collected. In the process of such purification, all salts, heavy metals, minerals, chemical impurities, organic matter, part of viruses, bacteria and microorganisms, as well as pesticides, herbicides, nitrates and even radionuclides and carcinogens are removed from the water.
The reverse osmosis technology uses a process known as cross flow, which allows the membrane to self-clean. While some of the liquid passes through the membrane, another part of it moves in the opposite direction, washing out the retained particles from the membrane. In the process of reverse osmosis there is a driving force that pushes the liquid through the membrane. The higher the pressure created by the pump, the greater the driving force. All mechanical impurities, contaminants and salts, which are retained by the membranes in the form of a concentrated salt solution, enter the electrolyzer system.

Electrolyzer system

The electrolyzer system in the device is necessary for generating electricity. It is based on the principle of electrochemical reaction using a network of electrodes (cathodes and anodes), which are located in a tank with a concentrated salt solution. The generated direct current is used to power the battery or to directly power the working equipment of the system – the electric motor and the control system.
Over time, patina forms on the anode and cathode plates. A special ultrasound unit is able to automatically remove all the accumulated patina and the electrolyzer will restore work. After that, the saline solution with a coating is released into the drainage system, passing through a coarse filter.
The amount of discharged concentrated saline solution from the electrolyzer system into the drainage system is small and amounts to about 25% of the water supplied to the purification device. Purified water (about 75%) is sent for further purification for the preparation of drinking water, or to a buffer tank – a reservoir, from which it is then collected for industrial consumption. Industrial water can be used in steam boilers (contributes to efficiency boost by preventing corrosion), for use in agriculture and other industries.
A group of tanks with special filters is installed and used for the preparation of drinking water, its complete disinfection from impurities of chlorine, organic matter, chemical solutes, viruses, bacteria and microorganisms.

This device is designed for use both on the sea – on ships in the ocean, where demands for constant water supply on a limited space is high, and on the shore – at small productions plants and private households with more than 5 people living close to salt water sources.

• All reverse osmosis cleaning devices are designed to work in the following conditions:
• temperature of incoming water: + 10 ° С;
• iron content – not more than 0.05 mg / l;
• absence of free chlorine;
• SDI level – no more than 3;
• Salinity level – 1,500 mg / l

Stage III

UV decontaminator

An ultraviolet decontaminator is installed in the water purification system; it is an effective way to disinfect water without using heat treatment or hazardous chemicals. Water under the influence of UV rays is completely disinfected in a short time, while 99% of microorganisms, bacteria and viruses contained in water are destroyed. The sterilization method is non-contact, so water does not change its physical, chemical and taste qualities. After passing through the ultraviolet decontaminator, the water is directed to the schungite cartridge.

Stage IV

Schungite cartridge

Schungite is a natural mineral that has excellent sorption, catalytic, bactericidal and anti-inflammatory properties.
The uniqueness of schungite is due to the presence in it of a special, rare form of carbon molecules – fullerenes. Schungite saturates water with useful fullerenes C60 and C70, which have a beneficial effect on the human body. The bioceramic cartridge structures water molecules and improves its quality. The water that has passed through the shungit filter can be stored for a long period of time; it becomes not just pure drinking or cosmetic water, but also a molecular colloidal solution of hydrated fullerenes. These molecules are health-improving and prophylactic agents that have a multifaceted beneficial effect on the human body. Scientific research has established that fullerenes are powerful antioxidants, localizing aggressive free radicals in the human body, detrimental to the living cells of the body.

Stage V

Complex mineral salt filler

The mineralizer-linear cartridge is used in the system as the last stage of purification for water mineralization. The cartridge is used as an additional function to saturate the water after purification on the reverse osmosis system with calcium, magnesium, potassium, sodium, phosphorus, carbonates, bicarbonates, sulphates, chlorides, in quantities close to those in natural mineral waters to provide an optimal mineral composition of the water and to restore the pH level. The filtering substance of the cartridge is a complex filler of mineral salts (potassium, calcium, sodium, magnesium). The mineralizer is used to improve the taste of water and saturation of purified water with the necessary amount of mineral salts for its better absorption by the human body.
Having passed through all the filters of the Infinity SAV water purification system, water meets the strictest requirements.
