CERAMIC FILTRATION TO CLEAN WATER

MBR Upgrade

Status Quo

Traditional polymeric MBR solutions are susceptible to mechanical damage resulting in loss of filtration treatment capacity, particularly submerged flat sheet membranes. Hollow fiber membrane are limited to Chlorine exposure, can experience clogging and fouling when pretreatment either has issues or is bypassed, resulting in fiber breakage and reduction in capacity and effluent water quality.

Durability

Ceramic membranes have a longer lifespan compared to polymeric membranes, resulting in lower replacement and maintenance costs over the lifetime of the MBR system. Their durability and resistance to chemical and physical degradation ensure consistent performance and reliability over time.

Chemical and Thermal Stability

Ceramic membranes are more resistant to harsh cleaning regimes without degrading.

High Mechanical Strength

Ceramic membranes are built to last and reduce the risk or breakages and maintainance downtime.

Constant Water Quality

Ceramic membranes provide superior filtration performance, effectively removing suspended solids, pathogens, and contaminants from wastewater. This results in treated water of higher quality, meeting stringent regulatory standards and improving downstream processes such as disinfection and reuse.

Polymeric Membrane Replacement

Status Quo

Polymeric filtration exhibit a high filter quality, but they are susceptible to mechanical damage, have limitations with chemical exposure and pH and can experience failures with variable or high solid feedwater conditions.

Durability and Longevity

Ceramic membranes are highly durable and resistant to harsh chemicals, high temperatures, and physical damage. They have a longer lifespan compared to polymeric membranes, resulting in reduced replacement and maintenance costs over time.

Resistance to Fouling

Ceramic membranes have a smoother surface and smaller pore sizes compared to polymeric membranes, making them more resistant to fouling by suspended solids, organic matter, and biological contaminants. This resistance to fouling leads to longer operational cycles, reduced downtime, and increased system reliability.

Higher Operating Temperatures

Ceramic membranes can withstand higher operating temperatures than polymeric membranes, making them suitable for applications where elevated temperatures are present, such as industrial wastewater treatment, oil and gas processing, and food and beverage production.

Chemical Compatibility:

Ceramic membranes are chemically inert and compatible with a wide range of aggressive chemicals and disinfectants, making them suitable for treating challenging wastewater streams containing corrosive or abrasive substances.

Narrower Pore Size Distribution

Ceramic membranes offer precise pore size control and a narrower pore size distribution compared to polymeric membranes. This allows for more efficient removal of contaminants and pathogens from water, resulting in higher-quality treated water.

High Flux Rates

Ceramic membranes typically have higher permeability and flux rates compared to polymeric membranes, allowing for greater throughput of treated water and smaller footprint requirements in water treatment systems.

Environmental Sustainability

Ceramic membranes are eco-friendly and recyclable, contributing to the overall sustainability of water treatment processes. Their longer lifespan and reduced maintenance requirements result in lower resource consumption and environmental impact compared to polymeric membranes.

Performance in Harsh Conditions

Ceramic membranes maintain their filtration performance in challenging operating conditions, including high pH, high salinity, and abrasive environments, where polymeric membranes may degrade or become less efficient.

Gravity Sand Filter Upgrade

Status Quo

Sand filters are state of the art when it comes to drinking water treatment. They are durable and robust but have comparably poor filter quality and cannot filter micropollutants such as PFAS, radium or microplastic.

CERAFILTEC ceramic flat sheet membranes are robust and durable as sand filters but with enhanced filter quality due to ultrafiltration technology.

Higher Filtration Efficiency

Ceramic membranes provide superior filtration performance compared to sand filters. They offer precise pore size control, allowing for the removal of smaller particles and contaminants from water. This enhanced filtration efficiency ensures cleaner water output, meeting higher quality standards required in many industries and applications.

Compact Design

Ceramic membrane modules have a compact design, allowing for a smaller footprint compared to sand filters. This space-saving feature is particularly advantageous in installations where space is limited or where retrofitting existing infrastructure is necessary. The compact design also simplifies system integration and reduces installation costs.

Longer Lifespan and Durability

Ceramic membranes are highly durable and resistant to fouling, chemicals, and physical damage. Unlike sand filters, which require periodic replacement or replenishment of the filter media, ceramic membranes have a longer lifespan with minimal maintenance requirements. This longevity translates to reduced downtime and lower lifecycle costs for water treatment systems.

Higher Operational Efficiency

Ceramic membranes operate at lower pressure differentials compared to sand filters, resulting in lower energy consumption during filtration. Additionally, ceramic membranes offer consistent and predictable filtration performance over time, leading to more stable and reliable water treatment processes. These operational efficiencies contribute to cost savings and improved overall system performance.

Enhanced Water Quality

Ceramic membranes provide a more effective barrier against contaminants, including bacteria, viruses, suspended solids, and dissolved substances. By producing water of higher quality, ceramic membranes help meet stringent regulatory requirements and quality standards in industries such as food and beverage, pharmaceuticals, and municipal water treatment.

Flexibility and Scalability

Ceramic membrane systems are highly flexible and scalable, allowing for customization based on specific water treatment needs and capacity requirements. Whether for small-scale applications or large industrial facilities, ceramic membranes can be tailored to meet varying flow rates and water quality objectives.

Tertiary Upgrades

Status Quo

Seawater RO pre-treatment can be challenging due to the variable feedwater conditions, particularly around TSS, organic matter, oil and salinity changes. resulting in the reduction of treatment capacity commonly experienced with conventional multistage pretreatment solutions, and reduction in the life expectancy of polymeric pretreatment.

CERAFITLEC's solution

CERAFILTEC’s ceramic membranes are highly durable and can withstand harsh chemical and physical conditions (oily water, algae, etc.).
The ceramic membranes are also less susceptible to the rapidly changing conditions of the fed seawater.
Plus, due to the precise pore size distribution, the quality of the feedwater to the RO system is better. Hence the lifetime of the system increases.
