Activated carbon filter selection techniques

Activated carbon filter mechanism

activated carbon filter is a kind of mechanical filter tank, the shell is usually stainless steel or glass fiber reinforced plastic, internal filled with activated carbon, used to filter the free content in the water, microorganism, parts of heavy metal ions, and can effectively reduce the shade of the water. Activated carbon filter is a kind of commonly used water treatment equipment, water treatment desalination system as pretreatment can grade filter before adsorption can't remove the residual chlorine, which can effectively guarantee the equipment service life, improve water quality, pollution prevention, especially to prevent reverse osmosis membrane, pollution of ion exchange resin and so on more than the free oxygen toxicity. Level and adsorption was leakage of small molecule organic pollutants, such as peculiar smell, colloid and pigment, heavy metal ions in water have more apparent, such as adsorption removal effect, also have the effect that reduce COD. Can further reduce the SDI value of RO water, assure SDI< 5，TOC< 2. Oppm。 A, composition of the activated carbon filter,

filter vessel, bearing a basket with netting on top and the filter bag, used in filtering liquid, the liquid from the side of the filter vessel or below into the liquid into the mouth, by the above support on top of the filter bag into the filter bag, filter bag because of the liquid impaction and homogeneous pressure side, the liquid materials in the surface is evenly distributed throughout the filter bag, liquid along the metal support through the filter bag on top wall, in is being exhausted from port filter at the bottom of the liquid, filter out the impurity particles trapped in the filter bag, complete the filtration process. The product characteristic, is the replacement of filter bag is very convenient, basic no filtering material consumption, this machine is designed to filter, double filter, and can form a complete set of pump assembly on the mobile cart, as for can also filter everywhere, the rest parts are carbon steel and stainless steel, can undertake choosing according to different medium. Its scope of application is extensive, can be applied to oil, petrochemical, pharmaceutical, pesticide, paint, food and beverage.

2, the characteristics of the activated carbon filter

1, high efficiency: 24 hours of continuous work, do not need to stop back flush.

2, low operating cost, does not need high head, large flow of backwash pump.

3, low maintenance cost: in the operation process in addition to the quartz sand filter material without any moving parts, low fault rate and maintenance cost.

4, low one-time investment: does not need to set single coagulation pool, pool and other facilities for clarification, do not need to back flush equipment such as pumps and electric, pneumatic valve, volume is small, one-time investment.

5, small head loss: a single filter material and filter material clean and in a timely manner, head loss is small, the total head loss 0 or less. 5m。

6, inlet water quality requirements: can be subject to long-term concentration of 150 mg/L SS inlet water quality and short-time withstand the concentration of 300 mg/L SS impact and effluent is unchanged.

7, stable discharging water, filtering effect is good. Filter material clean and in a timely manner, to ensure high quality and stable water effect, no periodic water quality fluctuation phenomenon.

8, easy to reconstruction: the unit operation mode can be adopted according to the amount flexible increasing or reducing its number of filter, easy to reconstruction.

9, cover an area of an area small, beautiful appearance, the traditional three-step reclaimed water treatment process is an organic whole, save land about 70 - 80%, more beautiful, compact appearance.

3, activated carbon filter technology parameters of filter filter speed: 8 ~ 30 m/h

backwash time: 8 ~ 10

working pressure: 0 or less. 6 mpa

when cleaning filter material head loss: 0.

design temperature: 5 ~ 4000 c

single-layer sand filter height: 700 mm ( Used for circulating water sand filter height 500 mm)

backwash intensity: 13 ~ 15 l/s & # 8231; Height: m2

double filter, sand filter height 500 mm, anthracite lu: liao, height 500 mm

backwash expansion degree: 40 ~ 50%
