FILTRATION SOLUTIONS FOR THE MINERALS INDUSTRY
Tetratex ePTFE Membrane Filter Media:
Optimizes filter performance Increases bag life and production rates Reduces downtime
Reducing energy consumption and environmental emissions are two of the greatest challenges facing the minerals industry today. Donaldson Membranes Tetratex ePTFE filter media can help overcome these challenges.
Tetratex filter media can enhance the performance of your fabric filter by utilizing surface filtration technology as opposed to traditional depth filtration methods.
FILTRATION CHALLENGES
The benefits of
Excellent cake release capability and low cake formation allows for reduced cleaning and less mechanical stresses. This helps to prolong bag life and reduce bag changes.
Reduced Downtime
3 Increased system airflow can be achieved through reduced filter pressure drop, significantly reducing the cost per BTU of product.

2Production Savings
Reduced Emissions
Reduced Energy Consumption
Near-zero emissions can be achieved due to the microporous structure of the membrane. Particu-late is collected on the surface, reducing environ-mental emissions within regulatory limits.
Significant savings in power consumption can be achieved by maintaining required airflow at a reduced filter DP. Surface filtration principles inhibit particle migration resulting in increased cleaning efficiency.

The use of Tetratex media could significantly reduce the cost per ton of product and increase mill capacity. Membrane filter media has a lower pressure drop than conventional media which results in less energy being utilized.
TETRATEX IMPROVES AIRFLOW RATE TO 179,500m3/h
The employment of Donaldson Membranes Tetratex Polyester has substantially increased the airflow handling capability of the baghouse serving a difficult cement finish mill;
Results after 4 weeks
Flow rate increased to179,500m3/h Differential pressure decreased by 34% Cleaning pressure reduced to 5 bar resulting in lower energy consumption and fewer cleaning cycles The plant manager was impressed with the results
TETRATEX INCREASES PRODUCTIVITY BY 300 TPD
Improvements after the installation of the Tetratex Acid Resistant Woven Fibreglass fabric filter bags to the kiln were significant;
Results after 4 weeks
Flow rate increased by 25% Particulate emission were kept below 20 mg/Nm3
Air to cloth ratio increased by 69% Productivity increased by 300 TPD Bag life increased 5x
