Filter media prepared in aqueous system including resin binder

A process for preparing a separator having at least one glass fiber media stage;

• the process of including a step of:
• (a) including, as a glass fiber media stage in the separator, a glass fiber media stage at least 12.7 mm thick prepared according to a process of:
• (i) preparing an aqueous slurry including glass fibers;
• (ii) forming a fiber matrix from the glass fibers in the aqueous slurry;
• (iii) providing, from an aqueous system:
• a resin;
• and, an inorganic agent to precipitate the resin into the fiber matrix;
• and,
• (iv) curing the resin in the matrix with the inorganic agent present to form a glass fiber matrix with resin distributed therethrough.

A separator having at least one glass fiber media stage;

• the at least one glass fiber media stage comprising:
• (a) a formed media tube having media at least 12.7 mm thick comprising:
• glass fiber media;
• resin and inorganic agent formed from an aqueous dispersion including the glass fiber media, resin and inorganic agent.

A process for preparing a separator having at least one glass fiber media stage, the process including a step of:

• (a) including, as a glass fiber media stage in the separator, a glass fiber media stage having a thickness of at least 12.7 mm and made according to a process of:
• (i) preparing an aqueous slurry including glass fibers and resin;
• the resin being in an amount to provide a resin solids content within the range of 1.67 g to 2.02 g per gallon of water;
• and,
• (ii) forming a fiber matrix having resin therein from the glass fibers in the slurry.
