What is the best water filter system? Sand filters Vs Cartridge filters

A water filter removes impurities from water by means of a fine physical barrier, a chemical process or a biological process. Filters cleanse water to different extents for purposes like irrigation, drinking water, aquariums, and swimming pools.

Cotton filter:
Some manufacturers call it cartridge filter or Precision cartridge filter, cotton filter has a porous width of 2.0 and 5.0 micrometer which disallow passage of parasites trophoziotes and ova in addition to elimination of pollutants.

Filter precision is a type of water purification equipment is used to prevent impurities from entering the high-pressure pumps and reverse the process of osmotic membrane filtration accuracy is 0.10μm to 60μm and accuracy of nomination is to feed the non-volatility of pressure.

Cartridge filter has NO effect on Salt elimination, this means it cannot used as a salts filtration system.

Main usage
is in tap water in your house to purify water after it had been salts removed by a national company or whatever water supplier.

Precision cartridge filter is designed with a tube of 7 filtering components of polypropylene. Filtering accuracy is 5μm and length 750 mm.
This filter cartridge contains a filter with a capacity of 3M3 / hour.



When the differential pressure of the cartridge used more than 0.07Mpa, should the user to change one of the components of the filter precision filter our own designer neutral structure which facilitates the process of replacing components.

Silica sand filter:
Also known as the mechanic filter and A biosand filter (BSF) is a point-of-use water treatment system adapted from traditional slow sand filters. ,and Silica sand filter is a type of water purification equipment used primarily in the granular remove impurities, suspended solids, colloidal, and other materials in the water.
Also there is a slow filtration sand filter and a rapid or fast sand filter.
Silica sand filter is a type of stainless steel and multi-media filter that 600mm inside diameter of the filter there is a good kind of silica sand. Higher layer filtering is usually more than or equal to 1200mm under normal working condition, the total production of water and sanitation 3 cubic meters per hour.
Current designs include the speed of the water to be about 10m /h.

Silica sand filter control valve provider laundering rear Automatically, can achieve laundering rear manual.
candle filters vs sand filters
Filter sand is silica sand filled.. Filter media can be one or more of the material between the silica sand, anthracite, porous ceramics such as manganese sand grains. Higher layer filtering material more than 1200mm. It should be high filtration material is compatible with the requirements of the relevant technical.

Under normal temperature limit certain pressure, through flocculation, are wiped absorption and objection means the nomination, and impurities in the solution of the original SDI and water filter greatly reduced.

Besides, it is equipped with silica sand filter with protective devices and monitoring tools. Since the device has the function of the back washing the dirt or other contaminants can be washed away quickly with a small amount of water.. Filtration accuracy is 0.005-0.01m, and the Missile colloidal polymers of high organic matter can be removed effectively.

Silica sand filter is characterized by simple automatic control, the ability to handle large high-efficiency filtration, a small resistance, easy to operate, easy maintenance, etc..

The filter can be used silica sand along with other water treatment equipment, to be used in various water treatment plants, water purification and waste-water discharge.
