Advanced Water Treatment

Reverse osmosis, ultrafiltration, nanofiltration and microfiltration are advanced water treatment technologies because of the improvements they can make in removing contaminants. Advanced water treatment applications are used when clients are looking at recycling water streams or looking at utilising untreated water sources for alternative water supply. Typical sources include:

  • Wastewater streams

  • Bore water

  • Untreated river water

  • Storm water runoff

  • Biologically treated water sources

  • Process water

 

The water quality of the untreated water source, and the water quality requirements for the treated water stream determine what form of treatment is required. iH2OM have extensive experience in completing projects of this nature and focus in the following areas to ensure successful outcomes:

Software projections

iH2OM utilise specialist software to effectively and accurately design outcomes to minimise impact and cost for clients. We find that our water treatment experience with managing cooling water, boiler water and effluent systems positions us well to understand what water quality from treated water will have the most benefit from a cost-of-production perspective and also from the impact on existing plant and equipment from a corrosion / scaling potential.

Pre-treatment selection

Advanced water treatment technology requires gross solids and other coarse contaminant to be removed – typical operations will require self-cleaning screens, sand or glass media filtration and possibly carbon filtration. Chemistry may also be required to reduce impact of certain contaminants like coagulants or oxidation.

Advanced treatment selection

Based on water analysis, software projections and water quality requirements for treated water may result in the need for microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) or reverse osmosis (RO). In many cases more than one type of technology may be required to achieve the desired result.

Disinfection requirements

Treated water from the advanced treatment process may need to be disinfected – we can apply a number of technologies ranging from UV, chlorination, UV /hydrogen peroxide, ozonation, or chlorine dioxide.
