New NF membranes designated DKL-3000X and DKL-4000X have been developed. These membranes have excellent water permeability and separation performance at super ultra-low-pressure such as 0.3MPa. Separation performance of pesticides and humic acid through DKL-3000X and DKL-4000X membrane is compared to conventional ultra-low-pressure RO membrane (UTC-70U) and nanofiltration membrane (UTC-60). The water flux of DKL-4000X is higher than that of UTC-60 membrane and extremely higher than that of UTC-70U membrane.<BR>Application of these new NF membranes for drinking water production or pretreatment of seawater desalination has been expected.
