AFM ® does not channel so it is an effective barrier against Cryptosporidium and giardia. AFM ® does not incubate or discharge bacteria and will reduce the bacterial load of the product water. Also because of the better filtration performance, there are lower ...

How Filteraid Works

If, however, a given filter aid grade will remove of the suspended solids, a finer grade while giving a lower flow rate due to its finer structure, will not give increased clarity. The selection of the proper filter aid grade is a compromise between high clarity and low flow rate, and lower clarity and higher flow rate.

How Do You Remove Silica from Industrial Water and Wastewater?

Granular silica removal. Silica can exist in water as relatively large particles, known as silica granules or granular silicates. Granular silica removal is generally accomplished through physical chemical separation. The most common approach is lime softening, which is a process where calcium hydroxide (lime) is added to water to remove hardness.

Silica gel is a non-crystalline material with a molecular structure formed by bundles of polymerized silica (SiO 2). Gel-type desiccants are indicative of the weaker bond formed between water and the desiccant. Silica gel is the old type of desiccant and is not widely used in today's filter-driers. Selecting a desiccant
