An extensive pilot study of ceramic microfiltration (MF) in the Ceramac configuration for treating IJssel Lake water was conducted at a demonstration-scale. At a gross flux of 75 LMH, a backwash interval of 30 minutes, and a chemically enhanced backwash after the 11th backwash, a nearly constant specific flux of about 500 LMH/bar (corrected to a t...

The use of ceramic MF was evaluated for a secondary wastewater effluent was done with no oxidant, chlorine and ozone as pretreatment and with in-line coagulation. Coagulation was required for effective control of organic fouling of the membrane. Ozone with coagulant was effective for operations but ozone cost could be prohibitive....

This paper presents the results from a twelve-month pilot study using ceramic membranes on Lake Michigan water in a sustainable manner with a flux of 103 gfd (175 lmh), with chlorinated and acidic chemically enhanced backwashes, and with pre-treatment with polyaluminum chloride coagulation. They estimate that the cleaning interval could be up to 10...

This paper describes a process comprised of ion exchange, in-line coagulation and ceramic microfiltration (MF) tested for treating surface waters in southwest England. The membrane could operate at the nominal flux of 109 lmh. The process handled abrupt water quality changes by adjusting the coagulant dosage and with the normal course of backwashes...

Ceramic membranes are being considered for reuse applications due to their durability and the ability to use strong chemicals to clean the membranes. Some pilot evaluations of different pre-treatments to ceramic membranes have been completed, and more are underway. It is clear that membranes can perform well when the pre-treatment is optimized. Thi...

This paper focuses on pre-treatment with coagulation upstream of ceramic microfiltration for treating surface water on a pilot-scale in Andijk, the Netherlands. Two coagulation systems, i.e., a conventional coagulation/flocculation system and an in-line coagulation absorber (ILCA) are compared....

In the recent years, a new advanced treatment train including ozonation and ceramic microfiltration has been piloted. This pilot study evaluates the impact of combined ion exchange and ozonation pre-treatment on the performance of ceramic microfiltration treating wastewater effluent for water re-use....
