<p>A method of wastewater treatment comprising the steps of passing wastewater through a neutralization and/or chemical precipitation unit (1), passing the effluent from the chemical precipitation unit (1) through a microfiltration unit (2), and passing the effluent from the microfiltration unit (2) through a nanofiltration (3) unit, whereby the constituents to prevent the reuse of wastewater are removed from the concentrated wastewater containing inorganic ions is an effective, economical and simplified zero-discharge system which has the advantages that the flux decrease due to membrane fouling is prevented, the quality of treated water is improved and the washing frequency is increased.</p> |
