Wastewater Treatment

 

Wastewater Treatment

 Treated water quality exceeds the international standards for treated sewage water discharge and reuse in restricted irrigation. Wastewater is water that has been used and must be treated before it is released into another body of water, so that it does not cause further pollution of water sources.

GHAITH use the Treatment philosophy

Very high-high

Required Area for
Sewage Treatment Plant

Less than others (less
aeration area, less
sedimentation area , less sludge treatment
required)

Required

Energy Consumption

Low (only air pumps),
0.004-0.006 KW-hr/gal
(1-1.6KW-hr/m3)

High (air pumps and
large number of
mechanical motors
required), 0.011-0.015
KW-hr/gal (3-4 KWhr/
m3)

Very high (air blowers and large number of mechanical motors required) - up to 0.026 KW-hr/gal
(7 KW-h/m3), ref Stefan Geizler, Aachen University Chemical Engineering Institute

Maintenance &
Cleaning Process
(Chemicals)

Maintenance free self-cleaning process

Maintenance needed -
sludge removal and
chemical treatment of
sludge.

Intensive maintenance and
chemicals required for flushing and membranes cleaning

Replacement of Major Items

No replacement

(only for compressor)

Replacement of
electromechanical
parts (i.e .blowers,  sludge
pumps, recycling pumps, gears, etc.)

Membrane replacement periodically and other rotating parts

Possibility of Expansion

Unlimited

Limited

Operating Cost

Low (air compressor only, no electromechanical
equipment, low number of personnel required)

High (air blowers and large number of mechanical motors required, large number of personnel required)
