Mantec Technical Ceramics: ceramic filters, Star-Sep membranes, diffusers and refractories

Pyrolith and Coralith filter tubes, Star-Sep membranes, filter housings, diffusers, fluidisation tiles, Puremet filters, Ultralite refractories and Bullers rings. Selection and a quotation for your project.

Pyrolith and Coralith ceramic filter tubes

Pyrolith and Coralith tubes, made of aluminosilicate particles bonded by glass, clean compressed air, gases and aggressive liquids. The media withstand acids, alkaline solutions up to pH 9 and hot gases up to 900 °C. Filtration ranges from 0.3 to 100 micron.

Hot gases up to 900 °C
Alkalis up to pH 9
Filtration 0.3–100 micron
Tube length 114–1000 mm

Star-Sep ceramic crossflow membranes

Star-Sep membranes run in crossflow microfiltration: the star-shaped channel gives a 5 x increase in filtration area and lowers pumping energy. Elements come with 7 or 19 channels. The membranes can be steam sterilised and regenerated after fouling.

LP and FSSTH filter housings, membrane modules

Stainless steel housings carry ceramic elements for air, gas and liquid filtration and are serviced without breaking pipe connections. FSSTH high pressure filters are rated at 700 kg/cm2 at 65 °C. Star-Sep modules to PD 5500 hold up to 300 elements.

Ceramic diffusers for aeration and ozone

Fine bubble diffusers in alumina-based porous ceramics introduce air into activated sludge and ozone into drinking water. Ozone diffusion is for ceramic only, other duties can use EPDM membrane diffusers. Coralith C5 media is WRAS approved to BS 6920-1:2000.

Porous fluidisation tiles

Pyrolith and Coralith tiles line silo floors, fluidising conveyors and fluid beds: air passes through the ceramic and makes the powder flow. Typical air demand is 226–340 litres per minute at 69–138 mbar per 0.1 m2 of tile. Uses include cement, alumina, fly ash, gypsum and flour.

Puremet metal pouring filters

Puremet reticulated ceramic filters sit in the runner system, cup or gate to trap non-metallic inclusions and oxide films. They serve aluminium, stainless steel, super alloys, copper and zinc alloys, iron and steel. Filters are graded from 30 to 60 PPI.

No organic binders
Area 3 times the runner

Ultralite refractories for kiln cars

Ultralite Loose Fill replaces ceramic fibre, vermiculite and perlite in kiln car bases and covers classification temperatures up to 1250 °C. Ultralite monolithic refractories are rated at 950–1300 °C with densities of 325–645 kg/m3. Mantec cites energy savings up to 40% in kiln car bases.

Bullers rings and BPCD process control discs

Bullers rings sit on the kiln car next to the ware, and their shrinkage shows the heat work of the firing. Five ring types cover 750–1420 °C. BPCD discs, 20 mm in diameter and 5 mm thick, measure up to 1770 °C in kilns and sintering furnaces.

How to choose a Mantec Technical Ceramics product

Selection starts with the duty.

For compressed air, gases and aggressive liquids Mantec offers filter tubes and housings; for crossflow microfiltration, Star-Sep membranes; for aeration of water and bulk powders, diffusers and porous tiles; for metal pouring, Puremet filters; for kilns, Ultralite refractories and Bullers firing control devices.

Next come the material and size. The main porous media are Pyrolith and Coralith, and tubes range from 114 to 1000 mm long.

Gas and liquid filtration

Pyrolith and Coralith tubes remove solids, oil and water from compressed air and gas lines and withstand hot gases up to 900 °C. For sterile air the efficiency is 99.999% at 0.3 micron. Elements fit Aerox filter units or customer housings.

FSSTH high pressure filters are rated at 700 kg/cm2 at 65 °C. Porous ceramic flame arrestors work up to 900 °C on tank vents, flare stacks, lead acid batteries and off gas systems.

Star-Sep crossflow microfiltration

Star-Sep membranes run in crossflow mode: the feed flows along the membrane surface and part of the liquid passes as permeate. The star-shaped channel gives a 5 x increase in filtration area and lowers pumping energy; circular channel elements are also made.

Module housings are designed to PD 5500, or ASME VIII on request, in stainless steel, duplex and super duplex, for up to 300 elements. Pilot plant systems are available for trials on the customer feedstock.

Aeration of water and bulk powders

Alumina-based ceramic diffusers introduce air into activated sludge and ozone into drinking water; Coralith C5 media is WRAS approved to BS 6920-1:2000. Where ozone is not used, EPDM membrane diffusers are an option.

Porous tiles line silo floors, fluidising conveyors and mixers: 226–340 litres per minute at 69–138 mbar per 0.1 m2 of tile. For powders of 1500–2250 kg/m3 the bed loss is about 100 mbar per metre.

Foundry and kilns

Puremet filters of 30–60 PPI sit in the runner system, with about 3 times the runner area. Ultralite Loose Fill comes in two standard grades up to 1250 °C, and Ultralite monolithic refractories are rated from 950 to 1300 °C.

Ultralite UGA aggregate is made as UGA-10 up to 1050 °C and UGA-12 up to 1250 °C, in 0–1, 0–2 and 0–3 mm grains. Bullers rings and BPCD discs are used in over 45 countries to control the firing of bricks, roof tiles, sanitaryware and tableware.
