Purpose of Multi Media Filter:
(Multi Media Filter) Multi-Media Filter is used to reduce the level of suspended solids (turbidity) in incoming feed water. Suspended solids consist of small particles such as silt, clay, grit, organic matter, algae and other microorganisms. Incoming feed water that is high in suspended solids can cause a high (pressure drop and reduce the effectiveness of downstream filtration equipment such as reverse osmosis membranes and ion exchange beds.
Media filtration is the most effective method for removal of suspended organic and inorganic solids from water. The media filters operate on the same basic principle as natures own ground water filtering process. Contaminated unfiltered water enters the system through a deflector in the top of the filter and flows, under pressure through the media where solid particulate is entrapped. Media filter can operate for much longer periods of time, it can clean itself with automatic backwash system, backwashing is necessary because the media can hold more turbidity daily.
Where can use it?
Can use water softener to save all off: chillers machine, water jet cutting, home use for washing machine pipes taps, laundry and more...
What is “hard” water?
Water described as “hard” contains high levels of dissolved calcium and magnesium. Ground water obtains these Metals by dissolving them from surrounding soil and rock.
What problems are caused by hard water?
Hard water can cause costly breakdowns in boilers, cooling towers water jet and plumbing. Hard water can also lessen the effectiveness of soap . When hard water is heated; the carbonates precipitate out of solution, forming a scale in pipes and surfaces. This scale is composed of mostly calcium carbonate, calcium sulphate, magnesium carbonate and magnesium Sulphate. The resulting scale can end up completely plugging pipes and restricting flow. In boilers the scale prevents efficient heat transfer and will have to use a lot of energy to provide hot water and can cause metal boiler components to overheat. Soap is less effective in hard water because it reacts to form the calcium or magnesium salt of the organic acid of the soap.
When hard water is passed through the resin bead, the calcium and magnesium ions have a stronger positive charge than sodium does. As a result, the calcium and magnesium have a stronger attraction to the negatively Charged resin bead than sodium does. The sodium ion is then ‘kicked off’ the resin bead as the calcium and magnesium take its place (and remains attached to the bead). As a result, the less desirable calcium and magnesium ions are exchanged for more desirable sodium ions. It is important to note that the salinity of the water does not change; it is simply an exchange of one salt for another.
How is hard water treated?
Water is made soft by the use of a water softener using ion exchange resin. The troublesome calcium and magnesium ions in hard water are exchanged for sodium, which is much more soluble and does not precipitate out to form scale or interfere with soap. Ion exchange resins are very small porous round plastic beads For water softening applications, the polymer Structure of the resin bead contains a fixed negative ion that is permanently attached. This cannot be removed. In simple terms, the resin bead has a fixed negative charge. Each negatively charged exchange site can hold a positively charged ion. In this case, sodium (which has a positive charge) is attached to the exchange site (negative and positive charges attract – think of magnets) In the end you have a mobile sodium ion attached to each of the fixed negative charge on the resin bead.
Eventually, the resin beads become saturated with hardness such as calcium and magnesium and there are no more exchange sites left to produce soft water. The resin beads have reached exhaustion and must be Regenerated.
How does regeneration work?
In simple terms, the ion exchange resin is soaked in a strong solution of sodium chloride (brine) where the sheer volume of brine solution causes the calcium and magnesium ions in the resin beads to become dislodged. At the same time, the sodium in the brine solution again becomes affixed to the resin bead. After regeneration, the excess brine and hardness causing ions are rinsed to drain and the resin beads are ready for use again.
Ultra violet UV
Ultraviolet or “UV” is a type of energy found in the electromagnetic spectrum, lying between x-rays and visible light. Although we cannot see UV light or rays, we are exposed to them every time we step out into the sun.
UV Water Purification systems use special lamps that emit UV light of a particular wavelength that have the ability, based on their length, to disrupt the DNA of micro-organisms. These UV light waves are also referred to as the Germicidal Spectrum or Frequency. The frequency used in killing micro-organisms is 254 nanometres (nm). As water passes through a UV water treatment system, living organisms in water are exposed to UV light which attacks the genetic code of the microorganism and rearranges the DNA /RNA, eliminating the microorganism's ability to function and reproduce. If a microorganism can no longer reproduce, it cannot replicate, therefore it cannot infect other organisms with which it has contact. This process of exposing water to UV light is simple but effective, destroying 99.99 percent of harmful microorganisms without adding any chemicals to water.
UV is Safe.UV disinfection has come a long way since it was first invented. And although UV is a new idea to some, ultraviolet technology has been used for decades by municipal water suppliers and commercial water bottling plants.
While most skin cancers are a result of exposure to UV rays in sunlight, the UV rays in water disinfection UV system do NOT cause cancer. The entire process of exposing water to UV light takes place in an enclosed container posing no risk to family or pets.
UV disinfection is approved by the EPA, and is an environmentally-friendly disinfection method as it is a chemical-free process and creates no byproducts. Because UV is simple, swift and safe, millions of homes and businesses now use ultraviolet technology to disinfect their water.

Say Goodbye to Chlorine in Your Shower and Bath with Shower Filters
Most people regard a hot shower or bath as one of life's little pleasures. However, what many people don't realize is the danger of chlorine in the water. Although chlorine is universally used to disinfect water, it is not safe for drinking, showering or bathing. Putting chlorine in the water is like starting a way to Cancer, heart trouble, premature senility; both mental and physical are conditions attributable to chlorine treated water supplies. It is making us grow old before our time"
And now we have shower filter is very effectively removes chlorine and other contaminants including iron, arsenic, mercury, dirt, sediment, odours. Enjoy smother softer skin, and reduce skin rashes, with less sinus irritation and healthier hair
All household water is chlorinated. Chlorine is destroys the proteins in hair and skin. Hair can become dry, and sensitive skin can become itchy and irritated. Filtering both drinking and bathing water should be a priority if you suffer from skin disorders or chemical sensitivities
Enjoy a safe chlorine free shower, decrease stinging and burning eyes, reduce respiratory problems, lower the risk of disease, enjoy smoother softer skin, and reduce skin rashes, with less sinus irritation and healthier hair.
