Ceramic filtration is an innovative technology applied for water treatment and effluents, and for improvements in production processes. It has highly competitive advantages over common technologies and excellent investment costs.
Based on inorganic membranes, a type of porous fine ceramic filter that is sintered from alumina, titanium, or zirconia by ultra-high temperature. Inorganic ceramic membranes typically have an asymmetrical structure with porous support and an active membrane layer. Macroporous support ensures mechanical resistance, while the active layer serves as a means of separation and with alternatives from microfiltration, ultrafiltration and nanofiltration (from 10’m to 1 kDa).
Inorganic ceramic membrane always works in cross flow filtration (tangential flow filtration). The cloudy fluid passes through an inorganic membrane layer within the channel at high speed. Driven by transmembrane pressure (TMP), the clean liquid with micromolecules passes through the membrane layer vertically to permeate. The solid and large molecule is rejected in retention. The feeding fluid is thus clarified, concentrated, and purified.
Advantages of CRM ceramic membranes:
- Fine separation accuracy with narrow pore size distribution
- Excellent resistance to strong acids, caustics, oxidation chemicals, and organic solvents
- High thermal stability and sanitized steam
- High abrasion resistance and high strength (long service life)
- High flow, backwash capacity, high efficiency
- Easy operation with low maintenance cost and low labor cost
- Less waste disposal cost
- Less CAPEX and OPEX
- Compact design with less footprint
- CRM multichannel tubular membranes

CRBR for primary brine refinery in chlor-alkali
TFT developed a new primary brine refining technology with integrated CRBR ceramic membrane separation process; In this process after mixing with Na2CO3 and NaOH, said reaction mixture can enter directly into the ceramic membrane system and the reaction sediment is rejected by the membrane due to its high filtration precision.
CRM membrane for Water - Oil emulsion treatment
TFT has been using ceramic membrane filtration in the Water - Oil emulsion treatment process, a technology that is being widely used due to its high efficiency for most emulsions and at a very low operating cost. Due to the high efficiency of this technology, the quality of the effluent water is very good and therefore it is reused through several operating cycles.
Pigmented water treatment by ceramic membrane
An excellent option for water treatment processes. The current water treatment processes are inefficient or do not comply with the required environmental regulations. Ceramic membrane treatment can separate dyeing and sizing agents from wastewater, both sizing agent and filtrate can be recycled. This technique not only solves the wastewater problem, but also recycles valuable chemical agents.
