Industrial type reverse osmosis water treatment equipment is designed to produce very high purity water. The treatment equipment of this series are suitable for various facilities, such as factories, food production, hospitals, villages, steam generators, ice rinks, hotels, etc.
~ Water treatment level:
The level of purification of the equipment provides conductivity up to 3μs, but it also depends on the quality of the water supplied to the equipment. Therefore, it is often necessary to install water pre-treatment filters and equipment (mechanical treatment, water iron removal, softening, etc.) before the equipment.
~ Principle of operation and treatment levels:
1. First stage of treatment
Initially, water is supplied to the equipment for the first stage of treatment. The first stage of treatment consists of a filter hull in which a mechanical filter is inserted. This mechanical filter is designed to filter water from mechanical impurities such as sand, rust-removing pieces, pipe sediments, etc.
2. Second stage of treatment
Water is supplied to a booster pump (type depends on the model of the unit), which provides the required water pressure on the diaphragms. This pump is able to run for a longer period of time and much more intensively than conventional pumps. With the pressure generated by the pump, water is brought to the second water treatment, to several membrane hulls connected in series or in parallel, which contain the membranes, which are the main elements of the treatment process of this water treatment equipment. These membranes act as a barrier to organic and inorganic contaminants, water-soluble solids, heavy metals, radioactive and carcinogenic particles. The fine membrane pores pass only water particles if their pore size is 0.0001 mm. Any larger particles are discharged together with the water into the wastewater.
The equipment is also equipped with a membrane self-cleaning system called "AUTOMATIC RINSE".
Each time the system is activated, the osmosis membrane starts self-cleaning. As a result of this process, the accumulated slag is washed away, as well as bacteria, etc. are removed from the membrane surface.
The technology is designed in a way, that part of the rinsing water is re-routed to the membranes (water is recirculated), thus ensuring water economy.
3. Third stage of treatment
Additional purification steps are often used in some cases, such as passing additional water through ultraviolet lamps, MIX-BED resin filters, demineralizing water, or adding dispensers to a specific mineral, pH level, etc. substances.
Purified water supply:
Three options are mostly used for a purified water supply:
Option 1: Clean, filtered water is brought into a pressure tank (hydrophore) designed to maintain pressure and to store purified water. The size of the pressure tank depends on the needs of the specific facility. The membrane inside the tank keeps the water pressure at the required level after filling the tank. This pressure ensures a fast drainage of water to the outlet in the consumption system. If the consumer needs a higher or lower pressure in the water system, it can be regulated by means of a pressure switch installed in the equipment.
Option No.2: Clean, filtered water is introduced into an open-type storage tank, which is equipped with additional water supply shut-off mechanisms, water outlet mechanisms and overflow mechanisms (the size of the tank depends on the needs of the specific object). When the amount of purified water entering the tank has reached the required level, the float mechanism shuts off the water supply to the tank. The water discharged from the tank is supplied to the consumer by a second-lift pump equipped with a pressure switch, a pressure tank and pump protection.
Option 3: Clean, filtered water is connected to a separate water pipe, which provides a purified water supply - for specific equipment and needs.
~ Equipment capacity:
|Model||Equipment capacity (average)||Recommended daily consumption||Amount of membranes|
The capacity of the equipment is affected by the following factors:
- Temperature - the power of the system decreases as the water temperature decreases.
- Pressure - system capacity increases as water pressure increases.
- Salinity and incoming water pollution - the capacity of the system decreases with increasing water salinity and total pollution.
Higher capacity reverse osmosis equipment is also available, ask the seller if necessary.
Equipment warranty: 3 years.
