SMALLER FOOTPRINT

The test site in Saudi Arabia was well selected. In 2010 the team has piloted, installed and operated the first ceramic flat sheet membrane equipment and invented the necessary cake layer filtration process for the removal of heavy metals. Over the past 5 years two other ceramic suppliers have been tested and installed inside the trains. Hence, the plant is the ideal site for comprehensive performance benchmark tests.

TECHNOLOGY PROSPECTS

The breakthrough high flux performance has been confirmed by the operator and CERAFILTEC received the product approval by the Ministry in August 2018 with certified maximum design flux rate up to 1,500 LMH. CERAFILTEC is currently testing alternative ceramic flat sheet membrane suppliers for high flux applications. 

AT CURRENT BENCHMARK STAGE

an up to

HIGHER FLUX PERFORMANCE

is expected by using single Alumina ceramic flat sheet membrane plates with CERAFILTEC’s high flux module housing design in water treatment applications.
