BIOH series paperboards are made of natural fibers and perlite filter aids , and are used for composites with high liquid viscosity and high solid content .
1.FeaturesHigh throughput , significantly improve filtration efficiency .
The special fiber structure and filter aids inside the cardboard can efficiently filter impurities such as microorganisms and ultrafine particles in the liquid .
2.The application is flexible , and the product can be used in different filtering scenarios :
Fine filtration to reduce microorganisms
Pre-filtration of protective membrane filtration .
Haze-free filtration of liquids before storage or filling .
3.Mouth has high wet strength , allows cardboard to be recycled to reduce costs , and withstands pressure transients in filtration cycles .

①The times it takes for 50ml of pure water to pass through a 10cm filter cardboard at room temperature and under 3kPa pressure .
②The amount of pure water that passes through 1m of cardboard in 1 minute under normal temperature and 100kPa pressure .
Gently insert the cardboard into the plate and frame filters , avoiding knocking , bending and friction .
The cardboard installation is directional . The rougher side of the cardboard is the feeding surface , which should be opposite to the feeding plate during installation ; the smooth surface of the cardboard is texture , which is the discharging surface and should be opposite to the discharging plate of the filter . If the cardboard is reversed , the filtration capacity will be reduced .
Please do not use damaged cardboard .
2 Hot water disinfection (recommended) .
Before formal filtration , use purified water above 85°C for circulating rinsing and disinfection .
Duration : When the water temperature reaches 85°C or more , cycle for 30 minutes .
The filter outlet pressure is at least 50kpa (0.5bar ) .
Steam Quality : Steam must not contain other particles and impurities .
Temperature : up to 134°C (saturated water vapor ) .
Duration : 20 minutes after the steam has passed through all the filter cardboards .
Rinse with 50 L/i of purified water at a flow rate of 1.25 times .
Shape and Size
The filter cardboard of the corresponding size can be matched according to the equipment currently used by the customer , and other special processing shapes can also be customized , such as round , special-shaped , perforated , draped , etc .
