Model BWP 53000 -Brackish Water Desalination Units
Reverse osmosis represents, nowadays, the most convenient and the safest technique for desalinization of different kinds of water. This treatment is replacing other technologies for water desalinization, thanks to the excellent combination between quality results and low running costs. Reverse osmosis also guarantees low energy consumptions and reasonable expenditure of chemical products. Furthermore, the waste water parameters fall within the sewage limits, therefore resizing more and more the problem of disposal of eluates (for example, for softeners and ion exchange resin demineralization units). Reverse Osmosis is the process that occurs when a saline solution comes into contact with a membrane permeable to water (and not to dissolved salts) at a pressure exceeding the osmotic pressure of the solution itself. The passage from water, poor in salts (permeate), occurs through the membrane, wherereas outside of the membrane waste water rich in salts (concentrate) is obtained.
Our manufacturing of reverse osmosis units for water desalinization covers a wide range of different solutions, according to:
- the type of water to be treated, tap, brackish or sea water
- for specific uses, drinking water, water for irrigation or industrial use
- the production capacity from 200 ltr/h to 25 m3/h of permeate, for brackish or tap water and from 10 to 2000 m3/g per sea water
WTEC Plants also carries on turn-key plants for sea water desalinization based on specific projects, up to di 10.000-15.000 m3/d.
In sea water desalinization of medium to large capacities, WTEC Plants uses turbines of energetic recovery and pressure exchangers in order to reduce energetic consumption up to 3 kWh/m3 of water produced.
Uses
- Brackish water desalinization to obtain drinking, irrigation or industrial water
- Well or tap water demineralization for industrial use (thermal power stations, food, pharmaceutical, electronics industry etc.)
- Sea water desalinisation obtaine drinking water or water for industrial use
