Multi-media filter to make one or several filter media makes water of high turbidity flow through agranular or non-granular material of a certain thickness under a certain pressure, thereby effectively removing suspended impurities in the water and clarifying the water. The commonly used filter materials including quartz sand, anthracite and manganese sand, etc. they are mainly used for turbidity removal of Water Treatment, water softening and pretreatment of pure water in preceding stages and the outflow turbidity can be below 3 NTU. The filter is mainly used for Reverse Osmosis. electrodialysis, ion exchange as well as softening and demineralization system pretreatment and can also be used as coarse filtration of industry water supplying with undemanding water quality, circulating cooling water, reuse water treatment of wastewater and recycled water, etc.
Activated carbon (AC) filtration has been used for many years to solve water problems. Activated carbon quickly and effectively removes chlorine and many other contaminants from water. Carbon filters are most effective at removing chlorine, sediment, SOCs and volatile organic compounds (VOCs) from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds. Carbon filters are usually apart of a more robust water filtration system. Untreated chlorine can cause irreversible oxidation to RO system membranes.
Activated Carbon and Carbon Block Water Filters
Carbon Water Filters have been used for centuries to filter impurities from drinking water. Carbon is a very powerful absorbant; one pound (half a kilogram) of carbon contains a surface area of 125 acres (0.5 square kilometers). The material has millions tiny pores, usually invisible to eye, and can absorb thousands of water contaminants. Several forms are commonly used in water filtration: Granular Activated Carbon ( GAC ), and Carbon Block. Activated Carbon is a material that has a positive charge, which helps attracting even more impurities. Generally, Carbon Block Filters ( or "charcoal water filters" ) have higher contaminant removal capability than GAC filters, and they usually have a higher cost.
Activated Carbon and "Block" Filters a usually rated by size of the particles it can remove. Typical ratings are from 50 micron (least effective) to 0.5 micron (most effective). We generally use 5 micron carbon blocks in our systems, because it gives us very effective absorbtion capabilities in combination with acceptable water flow rates. However, some applications exist where granular carbon is a better fit, such as in removing chloramines (combined chlorine).
Although various types of carbon exist, three are generally used for drinking water filtration: bituminous, wood, and coconut shell. Coconut shell variety is most effective for most water filtration.
1. Chlorine Removal: Activated carbon may be used to remove chlorine with little degradation or damage to the carbon. Dechlorination occurs rapidly and flow rates are typically high. However, this process requires an extensive amount of surface area, and organics in the water will eventually fill up and block the pores of the carbon. Ultimately, the AC filter will need to be replaced as its ability to dechlorinate the water will slowly decline. Spent carbon can be re-activated; however, re-activated filters should only be used in waste-water treatment applications. One advantage to using AC is its low operating cost and virtual "fail safe" operation once installed. One disadvantage is that as the chlorine is removed from the topmost layer of the media, the AC provides a damp environment ideal for the growth and proliferation of bacteria. Bacteria can cause problems in medical applications, or when using carbon as a pretreatment to reverse osmosis.
2. Removal of Organic Matter: As water passes through an activated carbon filter, organic particles and chemicals are trapped inside through a process known "adsorption".
The adsorption process depends upon 5 key factors:
a.physical properties of the activated carbon (surface area and pore size distribution);
b.the chemical makeup of the carbon source (amount of hydrogen and oxygen);
c.the chemical makeup and concentration of the contaminant;
d.water pH and temperature;
Active carbon filter can be controlled by manual or automatic type to start,wash,backwash,stop and other operations.
When pressure difference between water inlet and outlet reach 0.05--0.07 Mpa,backwashing must be started, the replacement period for activated carbon material is every half a year or one year.
Active carbon material is nutshell carbon,it is light weight,big holes,strong abrasion resistance and strong absorption,the filling height is:
actived carbon material: 0.6-1.2mm 1100mm, ---top layer
quartz sand material 0.6-1.2mm 100mm,---middle layer
quartz sand material 1.2-2.0mm 100mm,----bottom layer

SelfSource AutoBackwash is achieved by using the filtered raw water from two (2) or three (3) of the filtered cells and diverting over to the remaining cell. All cells are backwashed in sequence. The filtration process will continue while in the backwash cycle so the system is not "down" while backwashing. An independent backwash water supply is not required. Self-source system typically three or four filters to allow enough flow to reach 12-15 gpm/ft2 of filter bed surface back wash flow rate. During these periods (which typically last for several minutes per filter), the amount of filtered effluent flowing downstream of the filter is reduced or stopped completely by the amount of water required for backwashing, although the process flow into the system continues to while backwashing. It is easy to operate and maintain and a pressure sensor, timer or manual initiation can be used to initiate the backwash cycle.
