The Environment and Water Industry Programme Office (EWI) is soliciting Research Proposals that support the development of innovative water technologies from its infancy to the commercialisation stage. Novel, promising technologies will be funded in a coordinated manner so that there is holistic development in both technical and commercialisation aspects of the technology.
In recent years, membrane bioreactor (MBR) has emerged as a competitive technology in replacing conventional activated sludge processes for wastewater treatment, producing filtrate of better quality than tertiary treated effluent (turbidity < 0.1 NTU, TOC < 6ppm). PUB's research has demonstrated that the MBR is more robust and more efficient in terms of energy and chemical usage. Through MBR, wastewater recovery can be further improved to maximise the use of each drop of water multiple times. It is thus the challenge EWI to the industries to achieve ≥93% recovery from MBR filtrate.
This RFP aims to take a major step towards increasing MBR filtrate recovery from the current 75% (based on conventional reverse osmosis technology) to ≥93% (details in RFP 1201 Fact Sheet Annex A). Applicants are requested to propose innovative technologies or system approaches that can lead to a breakthrough in MBR filtrate recovery, while meeting the following criteria:
Applicants should adopt a system approach towards meeting the target of ≥93% water recovery from MBR filtrate, taking MBR filtrate as the feed water quality, provided in Fact Sheet Annex B, and achieving the target product water quality parameters, illustrated in Fact Sheet Annex C.
Proposed approaches for the development of full-scale 1MGD plants must consume energy of less than 0.6kWh/m3 for the entire system of water recovery from MBR filtrate and result in the unit cost of production of less than Please refer to the NRF's website for more details..40 per m3 of product water.
The unit cost quoted above is inclusive of operational cost such as chemicals, energy (@Please refer to the NRF's website for more details..26/kWh), etc, and capital cost with depreciation over 20 years at 4% discount rate, but exclusive of manpower and maintenance costs (unless otherwise stated). The proposed approach should minimize the use of chemicals and generate minimal sludge, so that it can be sustainably deployed in an urban land-scarce city.
Please refer to the NRF's website for more details.
