Partnership launches ceramic trial
Netherlands-based PWN Technologies, in partnership with Indian water treatment firm VA
Tech Wabag and Japanese membrane maker, Metawater, has launched a trial to
demonstrate the effectiveness of ceramic membranes as pre-treatment for seawater
This trial will be conducted in technical collaboration with PUB in all aspects. Other objectives of the trial are:
to produce enough data to determine initial optimal flux for stable conditions, and show stable and reliable operation, with minimal down-time and consistent treated water quality; and
to determine the filtered water quality with a mix of indicators including turbidity, metals, and organics, to ensure its suitability for downstream RO treatment.
Singapore was among the first nations to trial ceramics with a S$ 5 million (US$ 3.7 million), 1,200 m³/day demonstration plant at PUB's Choa Chu Kang waterworks with Metawater and PWN as partners. PUB ran the plant for 18 months.
