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.

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.

2 Best water purifier and disinfectant system (UV Vs Ultrafiltraion)

Disinfectants and ultra-purification systems are used intensively against very contaminated water sources as seawater or rivers as well as colored water or polluted with High molecular weight organic substances.
Water sterilization is another synonym.

UV filtration systems:
UV used to treat the water and purify it allows for the destruction of microorganisms (viruses, worms, bacteria and protozoa ...) in the water, because the waves of ultraviolet radiation can affect the work of molecules in living organisms to prevent duplication and reproduction as well as the destruction of microbes completely. Require this process to clear water (before filtering) inputs to get water cleared, and can be applied to water consumption, the process of rejection, the sea, and swimming ... treated water can be used for food consumption, agriculture, industry,...etc.

The use of ultraviolet rays to disinfect water is one of the modern processes are currently UV sterilizer (UV): It effectively destroys bacteria and viruses by altering the DNA which prevent them from multiplying . As is the case with ozone , it is necessary to use sterile secondary to prevent the growth of microorganisms .

The advantages of using ultraviolet radiation :
UV rays can be attractive as an antiseptic initial small systems for the following reasons :

• They are readily available
• It does not produce toxic residue
• Requires short periods of contact
• Ease of operation and maintenance

Limitations on UV usage: from the known problems that these rays may not kill Giardia lamblia or Cryptosporidium . And must be used only by groundwater systems that were not directly affected by the water surface devoid of neighborhoods that can not kill these rays . UV is suitable for water with high levels of turbidity or colored or if any organic material soluble ( because they use radiation to decompose thereby becoming food easy for bacteria and these substances can interact with them or absorbed by restricting their performance sterilization ) .

Filter the water using ultra- filtration :
Is a kind of water purification equipment , which unites technology filtration to filter water and is therefore different from other systems in the function of the membrane with a maximum purification , method of water purification this applied technology fiber vicious new and purification initial three stages to remove impurities in the running water purification high pore minute are smaller from 0.01μm to germs that accumulate rust and other dangerous substances and filtered out while the exact materials , metals and materials beneficial to human body are persists in permeate water while hard water completely excluded.

Fiber membrane allows the water cycle high yielding that do not block easily , since the components of the filter can be cleaned frequently. They enjoy the process of life and can be easily replaced

humans are preserved .

Because the filter ultra-filtration water running compression card flowing water , it does not consume electricity.

Capabilities of ultra-filtration systems:

RO Vs Ceramic Vs Activated Carbon filters

What is the best water filter system?: RO, Carbon or ceramic filters

You are going to purchase a water filter and do not what is the best water filter that fit your budget and whole house or apartment use.

Fair comparison away from marketing ideas and opinions of customers and vendors.
Comparison of the three types of the most common water filtration Systems:

Ceramic filters:
I recommend ceramic filters as a healthiest filters.
Analysis shows the effect of the output of a single treatment systems after 8 months of use that acidity and a few humans have been drinking sour, which is not healthy, so the consumer should not buy these filters Instead it resorts to the ceramic filters.

Perhaps the danger in drinking distilled water free of salts is not limited to loss of important materials such as sodium, potassium, chloride and trace elements such as magnesium in the human body, but up to a threat to human health through the most serious symptoms of diseases related to water pollution "water-borne diseases", or water salinity problems.

Comparing the types of filters sold in the market now with the ceramic filter, we find that:
Ceramic filter is clean and environment-friendly, unlike other types that cause change the cartridge, or one of its contents to the major pollution of the environment around us.
Water filters cheaper price now is ceramic filters also do not need to parts manufacturing because it is made of ceramic material and some of the other pieces that show the validity period of the largest in use, especially home and then say that the most suitable candidate for water for domestic use is the ceramic filters.

Ceramic filter for filtering salt water keeps the salts and minerals necessary for the body such as sodium, potassium and chlorine, as the Objection the gaps in the ceramic to prevent the passage of salts heaviest such as calcium carbonate limestone, which cause water hardness and not fit for use at home.

Activated Carbon water filter:
Active carbon filter is a type of water treatment equipment that uses property absorption in active carbon for water purification . A filter made ??of stainless steel and has a crust of active carbon " Charcoal " , which can absorb impurities biodegradable in water.
Used an earlier stage in the water treatment plants using reverse osmosis technology and the goal is to protect the RO membrane from damage by chlorine found in sea water.

Remove tastes and odors , and thus improve water quality and taste.
Effectively eliminate organic substances and chemicals and hazardous as after emerging active carbon filter water the density of organic dissolved materials should be less than 1mg/L.

Carbon filter is used primarily to absorb the residual chlorine and organic materials and some coloring materials , and hazardous materials in the raw water , and reduce the momentum in reverse osmosis plants .
Water filtration rate is usually higher than or equal to 1200mm.

The principle of the activated carbon adsorption:
The concentration of the surface layer of a balanced form a barrier of active carbon particles, and then is absorbed organic impurities in the active carbon particles. With the passage of time, the ability of active carbon absorption weaken due to the impact of reduced absorption. Moreover, the capacity of active carbon is in direct proportion to the last contact with the water. The longer the contact time, the greater the quality of filtered water.

In the quality of the water treatment system. Activated Carbon filter can absorb the  residual active chlorine , which was not able to remove it in the previous stages of filtration (pre-filtration is sand filters and cotton filters) to prevent the reverse osmosis membrane to be oxidized in the last nomination . Besides, it can be active carbon filter that absorbs small organic molecules and other contaminated materials leaked from the nomination of the previous phase , as well as the judiciary and off colloids , and coloring materials and heavy metal ions in water . As a result , it is reduced spatial to less than 5 and a table of contents is less than 2.0 ppm.

Reverse Osmosis filtration systems:
Semi-permeable membrane separates the solution and the pure solvent .
Osmosis : the decline of the pure solvent concentration will descend toward the solution.

If you add the external pressure on the solution and the pressure was higher than the osmotic pressure , the solvent in the solution will pop off pure solvent , separating the solution from the solvent . This is the reverse osmosis .

Using reverse osmosis membrane technology can isolate the solvent from water as well as the intensification of heat-sensitive metals .

However, the water must be provided convergence conditions silt density index of not more than 5 , and turbidity less than 1.0 NTU, and there is no residual chloride dioxide or similar .
The reverse osmosis devices are used widely in the field of electronics and chemical engineering , printing , pharmacy, and the areas of water .
Bottom

The basics of reverse osmosis desalination
Semi-permeable membrane permeability enjoy optional water can permeate through the membrane while salt can not.
Added pressure difference between the cabin and the cabin brine purified water is greater than the osmotic pressure , forcing the water to move the cabin from salt to fresh water compartment.

Inorganic ions , viruses and organic materials , colloids and other impurities in the water using reverse osmosis technology can be removed partially, and can therefore access to clean water of high quality.

More details about hardness of water.
Reverse osmosis device specifications:
RO system is the most important part of the water purification system, he can remove most of the salt, organic and most organic material and microbes from the water. During phase separation, not getting in late or change any pollution to the environment and RO device is small in size and specialized high rate of desalination in addition to the automated control that can be understood easily.
Devices reverse osmosis membrane is made of poly Amide, a substance is non-toxic and do not decompose faithful to the water . Average rate of a membrane desalination and exceeding 98%.

Systems utilize RO to purify water is designed on the basis of the characteristics of the various water which is also supported by software designed by professional engineers , and enjoy the life long work , along with that system osmosis reverse our adapts automatically with a rinsing and irrigation pharmacist , to wash away the pollution and ensure the efficiency of high-performance water treatment system .

I should mention that in the end:
All information used in comparisons of water filtration systems were brought to you on the basis of scientific ideas and techniques for each industrial filters that are traded in the markets now.
