APPLICATION OF ADVANCED MEMBRANE PROCESSES FOR TREATMENT OF WATER AND VARIOUS EFFLUENTS

Description

Available know-how, laboratory equipment and pilot units for application of Micro-Filtration (MF), Ultra-filtration (UF), Nano-Filtration (NF) and Reverse Osmosis (RO) to the treatment of potable water and of practically all kinds of liquid effluents.

Applications / Novel Characteristics

  • Improvement of potable water quality. Removal of all types of toxic substances (heavy metals, pesticides, nitrates, etc.).
  • Treatment of industrial effluents for useful materials recovery and water reuse.
  • Novel processes (based on MBR-Membrane Bio-Reactors) for municipal effluent treatment and water recycling.

Possible users / Customers

  • Industry: Applications to cope with all types of effluents (chemical industry, food processing, textile plants, etc.).
  • Municipal water and sewerage companies and various water treatment SME’s.

Examples

  • Phosphorus Fertilizers Industry, Greece: Industrial effluents treatment for recovering useful materials and water recycling.
