ABCO - Model RO-NF -Reverse Osmosis - Nanofiltration
ABCO Water designs and manufactures a range of fully customisable Reverse Osmosis plants, all of which are engineered using advanced 3D computer modelling and process design software. Equipment and pre and post treatment is selected based on both raw water quality and treated water quality requirements.
ABCO Water’s Reverse Osmosis – Nanofiltration (RO-NF) plants provide between 50-90% salt rejection at lower pressures. Typically used for softening applications and removal of pesticides and pathogens, they also remove iron and TOC (Total Organic Carbon), while allowing passage of monovalent ions like sodium and chloride. ABCO Nanofiltration systems are designed to treat feed water with TDS level <2,000 mg/L to produce potable water quality permeate without stripping out all the essential minerals.
- Alternative to water softening (ion exchange)
- Lower removal of essential minerals compared to RO-BW for potable water applications
- Ability to target removal of larger ions and other contaminates
- High recovery, typically 70-90% subject to feed water quality and treated water requirements
- Lower energy use compared to RO-BW
- Accurate simulation and consistent permeate water quality
- Energy efficiency, compared to other methods of desalination
- Scalability, skid/containerised plants can be easily scaled up or down
- Footprint, relatively small space required
- Low maintenance and ongoing operating costs
- Treating low TDS bore water for potable or process use
- Treating surface water for potable or process use
- Treating hard water for potable or process use (softening)
- Treating wastewater for process reuse or complaint discharge to environment
