Byelorussian Steel Works

To treat the wastewater from steel production, the following treatment layout has been installed at the Client’s site:

• chemico-physical pretreatment
• pressurized multimedia granular filtration
• anti-scalant dosing
• cartridge filtration
• CD-RO membrane filtration (first pass)
• spiral-wound RO membrane filtration (second pass)
• evaporator

mft CD-RO modules are essential to maximize the overall recovery rates, thus reducing the size and the operating costs of the following evaporation unit (ZLD process)

Parameter	Unit	CD-RO unit
Feed flow	m³/d	600
Feed conductivity	mS/cm	41 to 48
Flux at operating temperature	LMH	8 to 10
Recovery rate	%	35 to 40
Total rejection rate	%	96.1 to 99.2
Module pressure loss	bar	1.8 to 2.4
