ABSTRACT
Activation phase was used to produce activated carbon (AC) from
sugar cane bagasse (SCB). Whereas, the activation was done by two ways;
the first way had crashed granulate AC to fine powder (PAC) and the second
was the synthesis process nano-particles from granulate activated carbon
(NAC). The surface area of PAC has been estimated by Brunauer–Emmett–
Teller (BET) and characterization of NAC by using Transform Infrared
spectrum (FTIR) and Trasmission Electron Microscope (TEM).
The efficient adsorbent effects for each products and natural lime
stone were tested by its application on sewage water to improve its
physiochemical properties which included (pH, TSS, COD, BOD, TDS,
ASR, NO3, PO4, Mg, Ca, Na, Cd, Cu, Fe and Ni) through different soaking
period (0, 10, 15 and 20 day).
The results cleared that the effects of using individually nano
activate carbon was more efficient than PAC and natural lime stone to
purified sewage water treatment with 10 days soaking period compared to
other soaking periods. Furthermore, NAC exhibited the high efficiency
absorbent to remove metal ions (NO3, PO4, Mg, Ca and Na) and heavy
metals ion (Cu, Cd, Fe and Ni) and decrement BOD and COD from sewage
water. So that, it was selected to test its effects in combination with lime
stone on sewage water treatment.
Based on the obtained data the corresponding reduction values for
all studied traits were higher as compared to applying each of them
separately through soaking period 10 days.
It can be recommended that the combination of (NAC + limestone)
are a very good material in the field of sewage water treatment before
recycle it, which can be apply for reducing some pollutants in sewage water
after disposable.
