Product details

1、 Overview

Mechanical filters, also known as pressure filters, are an important component of pre-treatment and water purification systems for pure water preparation. They are made of steel lined rubber or stainless steel, and are classified into natural quartz sand filters, multi-media filters, activated carbon filters, and manganese filters according to the different filtration media Sand filters, etc., can be divided into single flow filters and double flow filters according to the water inlet method. They can be used in combination or separately depending on the actual situation.


2、 Working principle

A mechanical filter is a filter that uses one or several filtering media to pass the raw liquid through the media under a certain pressure, removing impurities and achieving the purpose of filtration. The fillers inside are generally quartz sand, activated carbon, granular porous ceramics, manganese sand, etc. Users can choose to use them according to their actual situation. Mechanical filters are one of the traditional water treatment methods that mainly use fillers to reduce turbidity in water, intercept suspended solids, organic matter, colloidal particles, microorganisms, chlorine odors, and some heavy metal ions in the water, and purify the water supply.



3、 Scope of application
Mechanical filtration is widely used in water treatment processes, mainly for turbidity removal in water treatment, reverse osmosis, and pre-treatment of ion exchange softening desalination systems. It can also be used for sediment removal in surface water and groundwater. The inlet turbidity requirement is less than 20 degrees, and the outlet turbidity can reach below 3 degrees.


4、 Performance characteristics

  • Low equipment cost, low operating cost, and easy management
  • The filter material can be used multiple times after backwashing, and the filter material has a long service life
  • Good filtering effect and small footprint
