Filtech 2019: Feedback on performance tests with Filtralite media compared to conventional media filters at pilot scale

The qualification tests conducted at the CIRSEE on Filtralite media in comparison with conventional media led to expect better performance in terms of water quality, increased filtration rate, longer filter runs and more flexibility to accept short-term degradation of water quality.

Contact filtration of humic waters in expanded clay aggregate filters

A series of contact filtration experiments are carried out to investigate the performance of an expanded clay aggregate (Filtralite) filter. It is demonstrated that expanded clay aggregates can be used in dual media down flow filters as the only filtering material. The density difference of Filtralite NC and Filtralite HC is sufficient to prevent intermixing of adjacent layers for the grain sizes.

New granular materials for dual-media filtration of seawater: Pilot testing

A comparative assessment of data from all dual-media filters tested shows that the combination, involving Filtralite NC 1.5–2.5 mm on top of Filtralite HC 0.8–1.6 mm, exhibits, overall, the best performance. The improved performance of this dual filter medium is attributed to the rough surface texture, with crevices that tend to better retain flocs.

Pilot test at Boden (SE) for biological removal of iron and manganese with Filtralite Pure Mono-Multi

The pilot filter with Filtralite which was studied in this work reduced iron and manganese significantly and removed more than 95% of both metals. The start-up period was about a week for the iron oxidation and significantly longer, closer to 70 days, for the manganese oxidation. [In Swedish]

Aerated biological filtration for the removal of ammonia and manganese in a major drinking water treatment plant in Hong Kong

Pilot test with Filtralite Pure HC 2,5-5 demonstrated that the nitrification process developed rapidly (2-3 days) in the aerated biological filter without "seeding" the filter media. By the beginning of the second week of operation, about 85% ammonia removal was achieved, with raw water ammonia concentration of up to 2.4 mg/l (N) and a filtration rate of 14 m/h.

Pilot test for Iron removal at Babite (CZ)

A pilot test was done at Babite (CZ) with Filtralite Pure Mono-Multi to confirm efficiency of iron removal technology for groundwater treatment, with target filtration rate 20 m/h and up.

Effect of ozonation/filtration on the raw water from Lac Mälaren

A Filtralite Pure filter was tested as an alternative to a GAC-filter, in combination with a pre-ozonation and a lower coagulant dose.

Alternative filter media for potable water treatment

Pilot trials, conducted by Thames Water, compared conventional sand and anthracite/sand media alongside crushed recycled glass and Filtralite Pure Mono-Multi. The Filtralite solution confirmed as the best one for treatment of eutrophic water from reservoirs.

Biological filtration of poor quality brackish water reduces Reverse Osmosis membrane fouling

Removing the manganese greensand in the existing filters and replacing them with Filtralite filter media resulted in a rapid improvement of treated water quality and a literal stop to frequent RO cleanings.
