Decolorization of Dyeing Effl uent by Novel Ultrafi ltration Ceramic Membrane from Low Cost Natural Material

Single Step Preparation of Zirconia Ultrafi ltration Membrane over Clay-Alumina Based Multichannel Ceramic Support for Wastewater Treatment

Zirconia ultrafiltration membranes are widely developed and used for past several years. But the conventional sol-gel methods of zirconia membrane preparation involve many steps. In the present study an attempt was made to develop defect free zirconia ultrafiltration (UF) membrane in single step coating of zirconia nanopowder suspension by slip casting method over multichannel ceramic support. ...

Dialysis, Ultrafi ltration, and Blood Pressure

overhydrated patients. This made it possible to relieve the uraemic patient from congestive heart failure and to control arterial blood pressure. Ultrafi ltration is generally applied continuously or intermittently, while the dialysis procedure (diffusion of substances across the dialysis membrane) is going on. During the last few years, short-time dialysis (3–4 hr 3 times a week or every other...

Decolorization of Continuous Dyeing Wastewater by Ozonation

Since discharge limits are becoming stricter for industrial wastes, textile manufacturers are searching for 3fficient and economical methods of pollution reduction. This is typical of :he situation facing the textile ndustry, especially in the area of :olor pollution emitted into the zarth's waterways. Ozone treatment ;o remove color from wastewater :ould be a solution to the problem of

decolourisations and biodegradations of model azo dye solutions using a sequence batch reactor, followed by ultrafi ltration

the main objective of this study was to investigate the effi ciency of biological treatmentof azo dye-containing wastewater with a sequencing batch reactor system, followed by ultrafi ltration.the performance of the system was quantifi ed by measuring the chemical oxygen demand and azo dyeconcentration. the biodegradation was carried out under combined alternating anaerobic and aerobiccondition...

Waste Engine Oil Remediation Using Low Cost Natural Clay Absorbent Material

The aim of the current research is to examine the potential of locally available natural clay mineral to act as an effective absorbent for waste engine oil treatment. The clay mineral was collected from the southern region of Saudi Arabia and was used without any kind of surface modification. The clay mineral was characterized by X-ray diffraction (XRD), X-ray fluorescence (XPS) and Braunner-Em...
