Our factory recommended granular activated carbon adsorption of mercury-containing industrial waste water purification operations of the following two. 1. Granular activated carbon column filtration method The test uses strip activated carbon, beacon charcoal and self-made activated charcoal produced by activated carbon plant, and is crushed and sieved to make 2.262～1.397mm (8～12 mesh). Sample 1 is industrial wastewater containing 0.94 to 2.8 mg of mercury, and the other is simulated industrial wastewater containing 1 to 6 mg of mercury. The carbon particles are packed in columns, and the waste liquid passes through the single-tube, double-tube and three-tube series activated carbon columns at a rate of 1 m∕h, and the adsorption rate of mercury is above 98% on average. The mercury-absorbing charcoal is returned to the use after distilling mercury, but the mercury absorption rate is slightly reduced (over 96%) when used again. Second, activated carbon powder adsorption method The mercury-containing wastewater treatment tank established according to the small test results is divided into three layers. The lower layer of the pool is below the surface of the earth and functions as catchment and sedimentation. After the wastewater is filled with the lower pool, the pump automatically draws the water into the upper tank to which the activated carbon powder is added. After the water is full, the compressed air tube at the bottom of the pool is automatically compressed and stirred for half an hour. After the sedimentation sample test, the supernatant is discharged after the mercury content meets the discharge standard; if it is not required, it is placed in the middle pool for repeated treatment. The secondary treated wastewater is discharged by a water pump through a microporous plastic filter tube. The wastewater purified by this method has clear water and no carbon powder. The treatment operation is intermittent, and each batch of mercury-containing wastewater is treated for 40 tons, and the process takes about 2 to 3 hours. When the treated wastewater contains 1 mg/L of mercury, 50 g of waste activated carbon powder is added per liter of the pharmaceutical plant. After treatment, the mercury content of the wastewater decreased to 0.0215 mg∕L, and the mercury removal rate was over 97%. The mercury-carrying carbon powder is recovered by distillation.
Heavy Duty Wire Stripper
Designed specifically for continuous high volume recovery of the toughest materials, Polymer Systems` heavy duty machines are precision machined with heavy steel plates and stress relieved weldments throughout. Massive construction of the cutting chamber, rotor and drive assembly provides maximum rigidity, allowing close knife settings without fear of misalignment or machine damage due to shock loads or continuous operation.
If you work with electronics or are in an industry that requires you to remove insulation from wires frequently,
Electrical contractors routinely create scrap metal products such as wire and cable,
aluminum conduit, cable tray, copper pipe, and even switchgear on the jobsite,
but they may not realize the value of these materials can significantly boost their bottom line.

Only Polymer Systems` granulators have a clear, unobstructed feed opening equal to rotor diameter for maximum performance through every inch of the cutting circle. This unique design maximizes granulator capacity, eliminates bottlenecks at the entrance to the cutting chamber and dramatically increases effective screen area for fast throughput. A special sound-deadening composite material is used for hopper walls on all Press Side, Large Part, Shurfeed 2000 and Heavy Duty granulators.
then you would do well to invest in a high quality automatic wire stripper.
The keys to getting the highest price for these items are knowing exactly how to collect and sort the material and bringing it to the proper scrap processing facility.
