Novel Backwash Procedure of Multibore? Membranes Using Backshock
The paper presents the general functioning and efficiency of the backshock with Multibore?ultrafiltration membranes which allows operation at higher flux and recovery rates. In addition, data from a pilot unit operated on two different types of water examines the mechanical strength due to the backshock on the membranes. Efforts to optimize and...
Long-Term Operation of Multibore Ultrafiltation Membranes
Long-term operation of several BASF / inge UF based water and wastewater treatment plants were investigated. Those plants operated on various water and wastewater sources and under fluxes ranging from 50 to 110 L/h.m2 with limited chemical cleans. Results presented demonstrate the capacity of the Multibore UF systems to operate under stable permeab...
Impact of organic matter on fouling propensity of a new ultrafiltration membrane with low adhesive surface - a study based on 10 different waters
Ultrafiltration (UF) membranes are widely used to treat surface water due to their capacity to remove colloids, particles, pathogens and virus. Today, they are also applied for reverse osmosis pre-treatment of wastewater reuse and desalination in order to address the problem of water shortage. However, membrane fouling by organic matter remains a k...
Ultrafiltration Membrane Operation Outside Manufacturer?s Specifications - Keokuk Waterworks? experience
Ultrafiltration membrane plants are typically operated within supplier process recommendations. Experienced plant operators may decide to test modifications of some process related parameters to evaluate their effect on the running costs. The paper presents long-term operation of the Keokuk Municipal Waterworks, Iowa, USA, where such experiments ha...
In-Line Coagulation Upstream Ultrafiltration - Comparison of Continuous vs. Intermittent Addition
The subject of this summary is the comparison between continuous and intermittent coagulant addition upstream of ultrafiltration membranes to remove organic compounds and thereby minimize the biological fouling of reverse osmosis membranes. In addition to the results of this comparison, the paper presents a new type of measurement called the ?Coati...
