Drinking water from Rivers and Lakes

Water from a surface water body The Self-priming pump  (1) feeds to the drum Mechanical drum grate (2). This step separates the coarse debris that is in the natural water. This debris is collected in Solid waste tank. (3). The debris-free water flows by gravity into the . Accumulation chamber (4), from which a Centrifugal pump (5) is fed to the reVODA Reactor (8).
Prior to feeding the reVODA reactor, a reagent prepared at the Reagent preparation and dosing station (6) is added to the water stream by the Dosing Pump (7).
In the reVODA reactor under the action of electromagnetic fields there is oxidation of treated water medium and decomposition of oil products contained in it, neutralisation of fats, phosphates, reduction of BOD and COD, separation of suspended solids and heavy metals. It is worth mentioning that under the action of cavitation and ozonisation there is a complete destruction of pathogenic microflora in the water.
After the reVODA reactor, the treated effluent enters the Sedimentation tanks (9)where the medium is separated into sludge and supernatant water. Sludge (hazard class V waste) is sent for disposal using the Impeller pump (10) and supernatant water is fed to the Centrifugal Pump (11) for final cleaning using the Ultrafiltration Unit (12). After ultrafiltration, the water enters the Accumulation chamber (13) (customer's equipment) for further intended use.

Rivers and lakes and are classified as water supply sources, which are characterised by such features as: low mineralisation, high amount of suspended solids, high level of bacteriological contamination, fluctuation of water parameters depending on the time of year. But the water molecules that are damaged(contaminated), when frozen, come out as 'broken' incomplete snowflakes
Rivers and lakes are also often contaminated with technogenic pollution as a result of discharges of industrial, domestic wastewater, and shipping traffic.
Another feature of such sources is the overgrowth microscopic single-celled algae — the so-called blooms, which are capable of to a great extent deteriorate organoleptic and allergenic properties of water.
In order to use river and lake water for domestic and drinking water supply purposes, it is mandatory to carry out qualitative and complex water treatment and purification in order to correct the chemical composition of natural water, improve its organoleptic properties and disinfection.

Contaminated natural water has a damaged structure. Properly structured frozen water looks like a snowflake under a microscope.
Proper water molecules are capable of joining into groups — clusters. The smallest basic cluster of water has only 6 molecules. But the purer the water, the more molecules join into clusters — 280 molecules and more are structured together. And that's how structured water is formed.
Modern scientific research proves the following useful properties of structured water and its favourable influence on biological processes in human, animal and plant organisms:
