Industrial water use is essential for many
processes, such as paper, oil and even gasoline production, water may be used
to dilute and cool a product, for example. Industries must effectively treat water that they use in order to not only reduce the costs of their
processes but also their environmental impact. One way, in recent news, to reduce
these costs is advances in the filters that are in place in a certain
industrial process.
If there are various particles and waster materials in the
water part of the process then the process cannot be fully up to standard or it may even not be able to perform the process correctly, so filters are needed.
However, the acidity or alkalinity of a process impacts the wear on filters,
which can also cause a problem. The use of metal and polymeric filters is
actually not as effective as the use of ceramic materials. The two types of
ceramic filters are, Alumina and Silicon Carbide. I always thought of ceramics
just as plates and pots! Yet they can also be useful in filtering techniques.
Ceramics themselves have many useful properties such as durability, resistance
to heat, and inertness. The inertness from my understanding must be one of the properties,
which makes it a good material for a filter in industry, as water can sometimes
be acidic and alkaline depending on the process, so resistance to corrosion
must definitely be a good property. The ceramic filter can also be made to have
fine pore sizes to ensure better filtration for the water process.
