Autonomous portable system for water purification

Designed specifically for use in the field and as easy to understand and maintain as possible. Does not require precious or rare items.

It can provide drinking water anywhere, without the need for access to a 220V network and pressurized tap water.

Built on the principle of reverse osmosis, it guarantees high quality cleaning.

At present, reverse osmosis is the most advanced solution in the field of providing water with safe characteristics for health and its purification.

The method is recommended by experts for use in EU countries, Canada, the USA, etc.

Water from any reservoir or rainwater can be used as a liquid for cleaning.

From one full charge of the battery, you can get about 55 liters of clean drinking water and 120 liters of purified water that can be used for household needs.

It works as follows:

When power is supplied, a tank with purified drinking water is checked. If it is full, the system will expect the water level in it to drop.

When the tank is not full, the high pressure pump is activated. It sucks water through a coarse mechanical particle filter from the dirty water tank and feeds it to a 3-stage filter system consisting of the following parts:

- 5 micron filter: removes large fractions from water (sand, dirt, rust) larger than 5 microns

-          Carbon filter: cleans the liquid from harmful chemical and organic compounds.

-          1 micron filter: cleans water from organic compounds and protects the membrane from the ingress of any particles larger than 1 micron.

Water purified with the help of filters enters the block with a membrane under pressure. In this unit, the flow is divided into permeate (water of the maximum degree of purification, the one that passed through the membrane, consisting of H2O and a small amount of gases that diffused through the membrane) and the concentrate - all the rest of the water, including dissolved salts.

Thus, it should be noted that salts and other compounds dissolved in water do not enter the container, but flow out.

The ratio between permeate and concentrate is about 30/70% for the new membrane and typical for Ukraine salinity of water from the Dnipro River.

The higher the salinity of the incoming liquid, the lower the permeate output from the same volume of filtered water.
