• Fouling-resistant wastewater reclamation (EDR,BioMF)

 Introduction

EDR

Electrodialysis reversal can successfully remove ions from water and wastewater by applying a direct current and reversing the polarity of electrodes periodically. The electric charge drives the ions penetrating anion or cation exchange membranes. EDR reduces conductivity and dissolved solids of bulk solution.

 

 Benefits

●High water recovery rate
●High desalination efficiency
●Easy process control of flow rate, voltage and current

 

 Features

●Soften hard water without chemical addition
●Remove sodium chloride, calcium, magnesium, sulfate and nitrate
●Capable of treating influent with SDI 10 times higher than RO
●Flexible pre-treatment using normal, micro or ultra-filtration

 

 Applications

● Desalination of RO concentrate
● Cooling tower condensate
● Salty groundwater
● City water
● Wastewater

 

 Patents

● TW 232772

 Introduction

BioMF

Biological membrane filtration process (BioMF) is a novel MBR technology, combining biological filtration bed zone with membrane separation zone, to treat organic wastewater and sewage. Non-woven carriers are filled up in biological filtration bed zone to obtain an excellent performance and stable operation. The non-woven membrane is subsequently submerged into membrane separation zone to filtrate particles and to obtain a high quality of permeate.
