PWNT CeraMac - Ceramic Membrane Filtration Process
CeraMac® is an innovative and cost-effective ceramic membrane filtration process designed by PWNT. This design allows the economically feasible use of ceramic membranes on surface water for large-scale applications, as well as in reuse and desalination pre-treatment applications. CeraMac® offers a compact proprietary system with multiple membranes mounted in a single vessel. This reduces the cost of the ceramic membrane system to a level which makes the system cost competitive.

Consultancy Services
PWNT provides consulting services on the study, design, optimisation and integration of water treatment technology. Over the past 95 years PWN has performed most of its own studies, engineering and optimisation of its own facilities.
PWNT ILCA - In-Line Coagulation and Adsorption Process
PWNT’s In-Line Coagulation and Adsorption (ILCA®) process was developed to minimise coagulation/flocculation footprint and to simplify pre-treatment upstream of CeraMac®. For most surface waters, coagulated feed water lowers the ceramic membrane fouling rate, but strong, large, setting flocs are not required for filtration with ceramic microfiltration. ILCA® was developed to provide only the necessary mixing at a short contact time for the CeraMac® system.
