Demineralization unit fit to treat water from brackish well water and liquid effluents with a salinity up to 8000 ppm

The unit is composed of:

Pretreatment section
Composed of a set of polyethylene containers 20" with polyester cartridge with a fil- tration degree up to 60 micron and wound polypropylene filter cartridges with a filtration degree up to 5 micron.

Pressurization section
Composed of a vertical multistage centrifual pump in AISI 316.

Permeation section
Composed of a set of reverse osmosis spiral wound polyammide membranes housed in glass fibre vessels jointed by means of stain- less steel pipings to high pressure section and PVC pipings to low pressure section.

Hydraulic control board
Including:

• Permeate, reject and recycle flowmeters.
• Pressure, recycle and reject regulators.
• Pressure gauges indicating the differential pressure on the filters.
• Pressure gauges indicating the pump operating pressure.
• Protection pressure switch for feed water low pressure.

Electric control board
Composed of:

• Magnetothermic switch.
• Thermal protection.
• Tension light.
• Manual ON/OFF with light.
• Hour counter.
• Automatic ON/0FF with light.
• Conductivity meter indicating the permeate quality.
• Timer.
• Ancillary controls transformer.

Main operations of the units are controlled by a PLC Siemens.
