RO Pretreatment
Consistent feed water.
Protection for downstream RO.
Reverse osmosis is widely used in water treatment and depends on effective feed-water conditioning. This application uses an inlet turbidity objective below 0.1 NTU, with the final feed specification set by the selected RO membrane and process.
Fine filtration removes suspended solids and colloids before RO. Super Cerafilter provides ceramic membrane separation to support a shorter, more maintainable pretreatment train.
More treatment stages.
More maintenance.
Polymeric ultrafiltration can achieve turbidity below 0.1 NTU, but often requires upstream sand filtration or dissolved-air flotation. These stages extend the process and add equipment and maintenance costs.
Membrane service life, cleaning performance and secondary environmental pollution from discarded PVDF materials require consideration over the operating lifecycle.
Ceramic pretreatment.
A simpler route to RO.
Super Cerafilter is designed to deliver filtered-water turbidity below 0.1 NTU. Suitable raw water can feed directly into ceramic filtration, allowing separate sand filtration or flotation to be omitted where the water analysis and solids load permit.
Long-life ceramic membranes support thorough cleaning and straightforward operation, reducing maintenance demands and avoiding PVDF membrane material in this filtration stage.
