Low Chemical Usage in Membrane Operations
The Oden Water Association installed an open platform style microfiltration treatment system to allow competitive bidding of replacement ultrafiltration membranes. The open platform style allows flexibility in operation in backwashing, […]
Wastewater reuse: Water Reuse for Lagoon Wasterwater Treatment
Ultrafiltration is an effective method of treating wastewater so that it can be used as reuse water. This can also be considered pretreatment to treatment of the wastewater by reverse […]
Optimizing the Use of Membrane Systems for the Removal of Disinfection By-Product Precursors
Online TTHM analyzers allow plant operations to be varied so that TTHM precursors in the bromoform family are adequately remove while the treatment process is optimized to reduce operating cost.
The Simplest Possible RO Pretreatment for Scale and Colloidal Fouling Control
In this paper, the simplest possible pretreatments needed for controlling of reverse osmosis (RO) membranes arising from dissolved salts and invisible colloidal particles will be addressed. The new generation of […]
Effects of Sodium Hypochlorite Ageing on the Cleaning Requirements of PVDF Based Membrane
PVDF based UF/MF membranes are susceptible to fouling and are generally cleaned using a chlorine-based solution. Exposer to sodium hypochlorite removes a portion of the hydrophilic additives from the membrane […]
Greywater Treatment and Reuse Optimization via UASB and MBR in Egypt
USAB treatment followed by MBR treatment based systems are able to treat greywater to effectively remove pathogens that allow this water resource to be used for direct irrigation of edible […]
Antimicrobial and Bacterial Anti-adhesive Properties of Polysulfone Membranes Modified with PAH/PAA Multilayers and Silver Nanoparticles
Polymeric microfiltration membranes used to treat wastewater are subject to file fouling due to the diversity of microorganisms present in wastewater. Surface modification of polymeric microfiltration membranes using polyeletrolyte multilayer […]
Membrane Bio-Reactor for the Removal of Pharmaceutical Compounds from Urine
The aim of the present study is to investigate the efficiency of the membrane bioreactor (MBR) for the elimination of Pharmaceutical Active Compounds (PhAC?s). Natural separated urine was artificially contaminated […]
Dual Stage Treatment of Domestic Wastewater Using Ceramic Microfiltration and Activated Sludge Process: Attempt for Agricultural Reuse
Ceramic membranes can be used in wastewater treatment using the MBR process to avoid damage to the membranes caused by highly acidic or highly basic wastewater. A ceramic membrane provides […]
Redefining Maximum Achievable Mixed Liquor Suspended Solids Concentrations in Membrane Bioreactors: Introducing Dissolved Oxygen in Membrane Bioreactors by Means of an Innovative Delivery Technology
The oxygen transfer efficiency in the aeration process plays a large role in determining the size and footprint of MBR equipment. Higher concentrations of MLSS tend to restrict the oxygen […]
