      Glass Microfiber Filters with Binder

      The glass fiber membrane is made of pure borosilicate glass fibre. The binder is added to enhance the mechanical strength of the glass fibre membrane and is mainly used to filter coarse particles (e.g. macromolecules, dust).

      In order to avoid chemical reactions with the filtered material, glass fibre membranes with inorganic binders are used for the filtration of organic substances and glass fibre membranes with organic binders are used for the filtration of inorganic substances.



      Features and Benefits

      - High wet mechanical strength

      - High erosion resistant

      High flow rate, high retention

      Glass Microfiber with Surface Coating Treatment 


      TCLP Testing Filters (Acid-treated with low metal content)

      For a long time we have been using landfills to dispose of solid waste, but the solid waste leachate from landfills is continuously polluting the groundwater and soil. With the accumulation of time, usually 3-5 years the waste leachate will pollute 1-2km of soil and groundwater in the landfill area, this process persists for 10-20 years, the pollution area will gradually expand.

      We need to constantly monitor the spread of contaminants in the area around the solid waste landfill, continually assess the potential risks, recover and dispose of waste leachate in a sound manner. The TCLP approach is commonly used in the assessment of landfill solid waste contamination risks.

      To dispose of hazardous waste in a United States municipal landfill, TCLP limits must fall within standard levels set for maximum contamination levels (MCLs). 

      Cobetter TCLP glass fiber membranes is made from 0.7 micron density, binder free glass fiber paper, which is acid-treated with low metal content to support TCLP testing by providing accurate information about TCLP limits to ensure the disposal plan.

      Gas-Absorption Filters (Copper acetate treatment)

      In the detection process of gas sensor, the composition of the detected gas is often complex, and it is easy to create cross interference between different gases. For example, for gas sensor that is indicated to detect carbon monoxide, hydrogen could be also on the gas sensor if hydrogen’s concentration is high in the test environment. Then hydrogen may also react and get a signal that the concentration of carbon monoxide is higher than the actual volume.

      In order to reduce the interference of some non-specific gases in air detection process, Cobetter glass fiber membrane with copper acetate treatment can absorb some interfering gases in the air, such as H2S, HMDS, etc.


      Features and Benefits

      Rapid diffusion speed.

      High adsorption capacity.

      Efficient adsorption for interfering gases.

      Low chemical background, no adsorption on detected gas.

      Provide customization with a variety of specifications and treatment options.
