Experimental Validation of Roughing Filtration Theory for High Turbidity Water

HAROON, HASSAN (NATIONAL UNIVERSITY OF SCIENCES AND TECHNOLOGY ISLAMABAD, 2012)

As an agricultural country Pakistan depends primarily on glacial melts and monsoon rains. Water from these sources flows down to rivers finding its way to Arabian Sea. The surface water thus collected is the chief source ...
SURFACE WATER QUALITY AND BENTHIC SOIL STUDY OF LEH NULLAH

Hussain, Faisal (NATIONAL UNIVERSITY OF SCIENCES AND TECHNOLOGY ISLAMABAD, 2013)

Heavy metals, in any stream are a damaging factor for the aquatic biota which naturally ingest the organic matter present in that stream. Also the presence of heavy metals in any stream decreases its self purification ...
Immobilization of Titania Nanoparticles on a Solid Support

FAHIM UD DIN, MUHAMMAD (NATIONAL UNIVERSITY OF SCIENCES AND TECHNOLOGY ISLAMABAD, 2012)

This study was conducted to find an effective way to immobilize titania nanoparticles (un-doped & silver-doped) on a suitable solid substrate so that this coated substrate would be used for photocatalytic elimination ...
COMPARING PERFORMANCE AND FOULING BEHAVIOR OF MEMBRANE BIOREACTORS (MBRs) FOR DOMESTIC WASTEWATER TREATMENT

AHMAD, AMAN (NATIONAL UNIVERSITY OF SCIENCES AND TECHNOLOGY ISLAMABAD, 2012)

Water scarcity and water pollution pose a critical challenge in many developing countries including Pakistan. One way to cope with the existing water scarcity is to reuse wastewater after suitable level of treatment. ...
INFLUENCE OF BIOFILM CARRIERS ON MEMBRANE FOULING TENDENCY AND TREATMENT PERFORMANCE IN HYBRID MEMBRANE BIOREACTOR

Rehman, Zohaib Ur (NATIONAL UNIVERSITY OF SCIENCES AND TECHNOLOGY ISLAMABAD, 2011)

In moving biofilm membrane bioreactor (MB-MBR) sponge carriers for biofilm growth were coupled with conventional submerged membrane bioreactor (C-MBR). This study compared the fouling propensity of C-MBR with MB-MBR and ...
