active carbon filter for water oil-water separation

Activated carbon filter for oil-water separation

I. Working principle 

Activated carbon manufacturing process including two process: one is the dehydration and coking, 2 it is activated. Thus forming the unique pore structure, and more than an enormous surface area, has the formidable physical adsorption ability. In addition, in the activation process, the results of the carbon surface area formed some functional group, such as oxygen, carboxyl, hydroxyl, carbonyl, these groups make active carbon adsorption and with chemical catalytic oxidation and reduction and performance.

Activated carbon filter using active carbon adsorption and decoloring itself is, remove the impurity liquid ability, the liquid, the purified adsorption and decoloring ability mainly embodied in the following aspects:

1, can absorb organic matter and bacteria in the water, colloid particles, microorganisms.

2, adsorption chloride, ammonia, bromine, iodine etc. Nonmetal material.

3, can remove metal ions, such as: silver, arsenic, bismuth, cobalt, hexavalent chromium, mercury, antimony, tin plasma.

4, can effectively remove chromaticity and smell.

II. Application range

Activated carbon filter is widely used in food, medicine, electronics, chemical industry, industrial effluent water treatment engineering of the industry is in the process of water treatment equipment, used to prevent the water pretreatment of follow-up equipments of the pollution of the pollutants, can also be used to improve water smell and color.

III. Structure characteristics

Equipment ontology is up and down with the ellipsoidal head cylindrical steel structure, filter material of Q235-A or 304 stainless steel lined with sulfur rubber anticorrosive, internal in the water inlet is lower, with A collection of water device, set on the device water filled 1200 mm and 200 mm of quartz sand activated carbon. Complete sets of equipment, there are all kinds of external device ontology control valves and flow meters, pressure gauge.

Activated carbon filter filled in for nut shell activated carbon carbon, with the proportion of light, porosity, wear resistance, the advantages of large absorption capacity. Fill in the high as follows:

Activated carbon          0.6 — 1.2 mm  1100 mm

Quartz sand              0.6 — 1.2 mm  100 mm

Quartz sand              1.2 — 2.0 mm  100 mm

IV. Technical characteristics and parameters

1, activated carbon filter accuracy, high water stability.

2, through their own retrieval and strain function, realization of automatic reverse wash, can deal with unstable water quality fluctuation, manual operation.

3,, activated carbon filter control system, operation precise sensitive reaction, can according to different water filtration precision and flexible.

4, cleaning efficiency, thoroughly, the system can be strong, can be life-long restorative filter use without having to change.

5, activated carbon filter reverse wash at the same time don't interrupt normal water production, continuous, stable and reliable operation.

6, reverse wash for short, the wash water consumption for normal produce a water yield only 0.001 to 0.002% of the province, save electricity, water, energy saving.

Working pressure:            < 0.6 Mpa

Hydrostatic test:              0.75 Mpa

Fill the turbidity:              < 2 mg/L

Working temperature:         5-40 oC

Operating velocity:            8-10 m/h

The wash strength:           12-16 L/m2. S

Packing height:              1400 mm

V. Performance characteristics

1, activated carbon filter structure reasonable, compact design adsorption filtering effect is good, cover an area of an area small, flexible and convenient installation mobile.

2, equipment less easyworn parts, no consumables, operation and maintenance expenses low, simple operation and management.

3, activated carbon filter application field wide, are suitable for different raw water quality and water requirements.

4, filter material life long.

VI. The selection of activated carbon filter

Activated carbon filter based on the size of the water and decide, based on the use of the different choice of A3 steel qualitative or stainless steel material.

Commonly used for granular activated carbon, grain size of 0.4 ~ 2.4 mm, shape of cylinder, ball, amorphous carbon, hollow ball, hollow pillar, etc. The surface for 500 ~ 1500 than m2 / g carbon, fine holes total volume of 0.6 ~ 1.18 m3 / g charcoal. But according to use water conditions and different to choose.

Activated carbon filter press carbon bed forms can be divided into fixed bed, expansion bed and moving bed three groups. At present, the extensive use of is fixed bed filter. Filter shell generally USES stainless steel and lining anticorrosive materials of the carbon steel.
