WHY CERAFILTEC Sand filtration vs. CERAFILTEC About 100 times smaller pore size - Best filtered water quality, free of suspended solids Real disinfection - Physical barrier for germs & bacteria About 15 times lower flow through velocity - Extremely slow filtration with less than 0.2 mm/s leads to maximum removal efficiency Reliable filtered water quality - Insensitive against feed water quality variations Maximum filtered water output - Lowest backwash waste means highest recovery rate Most compact design - Up to 5 times smaller footprint Sand media; UF membrane with 0.1 µ m pore size; Simple single-storey filtration basin without nozzle bottom Large pore size; Out-to-In surface filtration process Depth filtration - whole media body is used for separation process Due to the very compact design of CERAFILTEC existing sand filter plants can be easily rehabilitated using existing civil work structure but highly increasing filtered water quality and quantity PAGE 9 COMPARISON
WHY CERAFILTEC Submerged polymer membranes vs. CERAFILTEC Insensitive against chemicals and temperature Reliable filtered water quality without decline (no material ageing) Capability of high-pressure backwash leads to efficient membrane performance recovery without use of chemicals (no process stop) Highest flux rates - Up to 15 time less filter area Insensitive against high Fe, Mn concentration and turbidity Maximum filtered water output - Lowest backwash waste means highest recovery rate Very long life time - Less maintenance, service and Polymer hollow fibre and flat sheet Ceramic flat sheet membrane; replacement efforts membranes made of PVDF, PS, PES, Out-to-In filtration; PESM and other organic materials; Submerged suction pressure operation Out-to-In filtration; Submerged suction pressure operation The fully modular and highly compact design of CERAFILTEC enables a direct replacement of polymer membrane systems using existing filtered water tank and achieving at least same filtered water output PAGE 10 COMPARISON
WHY CERAFILTEC Pressurized membranes vs. CERAFILTEC Insensitive against high Fe, Mn concentration and turbidity - No risks of membrane module clogging No compaction of formed cake layers - Up to 10 times higher flux rate Very low transmembrane pressure - Especially deformable/ jelly-like particles cannot be forced into the membrane pores or even pass the filter Very long filtration duration without need of backwash - Highest recovery rate means maximum filtered water output (Semi) dead end filtration - Save on feed pump capacity Low suction pressure operation - High energy savings Tubular ceramic and polymer membranes; Ceramic flat sheet membrane; Easy maintenance options, e.g. use of high-pressure In-to-Out filtration; Out-to-In filtration; High pressure operation Submerged suction pressure operation water jet In any emergency case CERAFILTEC‘s single plate module concept enables to simply change separate flatsheet membranes with lowest efforts in maintenance, service and replacement costs PAGE 11 COMPARISON
WHY CERAFILTEC Other ceramic flatsheet membranes vs. CERAFILTEC Maximum flexibility due to fully modular concept with free selection of modules per tower and towers per rack No corrosion of rack equipment - Suitable for harsh applications, like ground and seawater or other challenging industrial applications Simple maintenance and service due to lift option of single towers (remaining towers stay in operation) Hydraulic design of up to 1,500 LMH - Up to 3 times higher module flow NFC tags on each module, tower, rack and train with Source: Meiden; meidensha.co.jp Source: ItN Water Filtration; itn-nanovation.com access to mobile service portal for simplifying Ceramic flat sheet membranes; Ceramic flat sheet membrane; operation, maintenance and permanent performance Two different rack sizes from each supplier with fixed number of modules; Modular design made in plastic without hoses; monitoring Surrounding stainless steel frame Rack design without surrounding frame Cost efficient replacement of single ceramic plates Most compact, flexible and highest performing design in the market PAGE 12 COMPARISON
