Mechanical filter, also known as pressure filter, according to the material classification has a mechanical filter, stainless steel carbon steel mechanical filter, filter material or filter by to have a quartz sand filter, many media filters, activated carbon filter, precision filter, in addition to iron and manganese filters, etc. , in the industrial production, need to deal with the filtering material is very much, different filter material condition is different, so should choose a correct filtering equipment is very important, you need to consider the various factors, the following introduce filtering equipment for everyone to choose what are the main factors to consider, hope to be of help.
1, the suspension ( Material) Filtering characteristics of the
before choosing filtration equipment, first to deal with the production of material conditions have a clear understanding of the need to filter. Should be measuring the concentration of suspension, the solid particle size distribution and so on, according to a preliminary determination is to choose the type of filtration equipment.
2.
rate of water in the process of production need to filter material quantity is big, the use of continuous or automation filter is good, if the amount of material handling is small, generally adopt the intermittent filter is more economic.
3, water treatment conditions filtering high temperature, volatile or toxic materials, must be special consideration. If suspending liquid temperature is higher, because the relationship between vapor pressure, vacuum filter is difficult, the pressure filtration is suitable. In the case of material toxicity is stronger, airtight filter must be used, in case of material leakage pollution of the environment.
4, the effect of the water filter to
the filter processing, have a plenty of recycling valuable solids, have a plenty of purifying the filtrate, have a plenty of both.
5, the structure of the filter and filter material
if concentrate corrosion resistance is not strong, the selection of filter machine for material requirement is unfavorable and exorbitant, otherwise the cost is higher. On the structure should be considered as far as possible simple structure model, in order to avoid maintenance difficulties.
mechanical filter in general at the beginning of the water treatment filter, the use is very strong, has also been widely available, widely used in the terminal filtration of sewage purification, water treatment, water treatment and other water filtration purification treatment.
