- High membrane porosity near 45% with nominal pore sizes of 0.04 and 0.2 micron
- Chemically inert across pH 0 to 14 and thermal resistance up to 800 degrees C
- Replacement FKM sealing gaskets and titanium adapters for pressure housings
LiqTech OD 146 mm Honeycomb Monolith Ceramic Membrane Modules
Multichannel honeycomb monolith cylinders with 146 mm outer diameter provide high active filtration area in compact pressure vessels. The R-SiC structure features Vickers hardness of 2930 kgf/mm2 to withstand abrasive feeds and 10 bar pressure. Ideal for high-solids recycling loops.
- Multichannel monolith cylinders with 146 mm diameter and lengths up to 1178 mm
- High filtration area up to 10 square meters per element in compact volumes
- Vickers hardness of 2930 kgf/mm2 for superior resistance to abrasive slurries
- Stainless steel 316L housings, Victaulic couplings, and profile seals
LiqTech QlariFlow™ Commercial Aquatic Ceramic Filtration Systems
Automated modular QlariFlow systems are engineered for commercial swimming pools, thermal spas, and aquatic centers. Ceramic membranes reduce backwash water usage by 70 to 80 percent while capturing cryptosporidium and fine particles. The skid includes an automated PLC control enclosure.
- Water savings of 70 to 80 percent on backwash cycles versus sand bed filters
- Complete physical barrier against cryptosporidium oocysts and particulates
- Compact modular skid design fits through standard equipment room doorways
- Replacement automated butterfly valves, dosing pumps, and transmitters
LiqTech Marine Scrubber Washwater Treatment (SWT) Systems
LiqTech marine closed-loop and hybrid scrubber water treatment systems are operational on over 170 commercial vessels worldwide. The technology removes polycyclic aromatic hydrocarbons, soot particles, and heavy metals per IMO MEPC standards. It integrates with EGR and ICER engine circuits.
- Over 170 marine installations across global container vessels and tankers
- Verified compliance with IMO MEPC.259(68) and MEPC.340(77) discharge limits
- Engineered integration with exhaust gas recirculation EGR and ICER circuits
- Replacement turbidity sensors, dewatering units, and booster pumps
LiqTech Heavy Industrial Wastewater & Produced Water Systems
LiqTech industrial ceramic systems are engineered to separate stable oil emulsions and treat produced water across energy fields. The units reduce free and dissolved hydrocarbons below 5 ppm and provide total clarification ahead of RO membranes. They operate continuously under heavy fouling.
- Hydrocarbon separation below 5 ppm from stubborn industrial oily emulsions
- Protection of downstream reverse osmosis elements from organic fouling
- Recovery of mining process effluents and metal processing rinse waters
- High-pressure feed pumps, backpulse accumulators, and instruments
LiqTech Silicon Carbide Diesel Particulate Filters (DPF)
Wall-flow honeycomb ceramic filters are engineered to trap diesel particulate matter and soot from heavy-duty exhaust streams. The high porosity of silicon carbide ensures particulate capture efficiency exceeding 99 percent with low backpressure. Sized for marine engines and power generators.
- Particulate and unburned soot filtration efficiency exceeding 99 percent
- Peak thermal resilience up to 800 degrees C during active regeneration
- Optimized channel geometry maintains low engine exhaust backpressure
- High-temperature canning shells, mounting clamps, and Delta-P sensors

Engineering Sizing and Membrane Selection for Harsh Fluids
Selecting LiqTech ceramic membrane systems requires evaluating feed chemistry, oil droplet distribution, suspended solids concentration, and target flux recovery.
Hydrodynamic modeling guarantees optimal crossflow velocity distribution across all channels and avoids boundary layer polarization during oily water treatment.
SpareX engineering teams support comprehensive skid sizing, pressure vessel integration, and prompt global delivery of verified replacement monolith elements, FKM seals, and control transmitters with full manufacturer technical documentation.
