Brackish water
Reverse Osmosis

Lenntech Reverse Osmosis series for desalination systems for brackish water are designed for feed water with a TDS (Total dissolved solids) less then 5000 ppm. Due to some new developments in membrane technology the LennRO systems work with low pressure RO membranes (12 to 20 bars).

With systems as small as 250L/hr and up to 25 m3/hr we can treat most of the demands. The standard design has a prefilter, high pressure pump, Low Energy Revese Osmosis Elements, Flow meters on permeate, concentrate and recycle stream, and is microprocessor controlled.

Optional, all systems can be equipped with a dosing system for antiscalants or biocides to protect the membranes against scaling or fouling. Lenntech can also provide other pretreatment systems like multimedia filters, water softeners of de-ironing filters.

The LennRO installations are used in many industries, drinking water facilities and agriculture applications:

• Desalination of process water
• Drinking water filtration
• Drinking water purification
• Reduction of TDS and total hardness
• Surface water treatment
• Optimization of water quality for drinking water
• Desalination of agriculture water or well water
• Environment (Recycling of process water)
• Desalination
• Nanofiltration (optional)
