Abstract
Medical labs discharge their waste water to the general sewarge
network without treatment , these waste water contain pathogens
causing diaseases(for example HCV, HBsAg). This work aimed at
disinffectanting the wastewater generated from medical labs, to be
safe to gdischarge in sewerage network .
Our samples are collected from the waste of out patient clinic lab
in certain university and the wastewater are tested for :
1-Presence of HBsAg using ELIZA Technique.
2-Presence of pathogenic bacteria.
3-The values of COD, BOD.
4-After that, the waste is treated by chemical disinffectants
(Ethylalcohol, Chlorine, Formalline, Cidex, H2O2, Clorohexidine
) to disinffectante the wastewater and repeat the examination of
the presence of HBsAg and pathogenic bacteria and determine the
value of COD, BOD.
5-The sample is dilluted (1:1) and treated using the same previous
disinffectants and is tested for presence of HBsAg.6- The steps 1-5 are repeated on other samples of wastewater of
the labs .
The results show :
1-No pathogenic bacteria in the wastewater of this labs.
2-The values of COD, BOD are comply with the regulations set
by law 93/62.
3-The values determined of HBsAg in the untreated waste are
more than the positive control used , the chemicals give different
degree of effeciancy in disinffected the wastewater, but Cidex
resultes show the detection of HBsAg by ELIZA was not impaired
by Cidex(gltaraldehyde at1%)wich showed complee viral
inactivation ,so it is the best used as a chemical disinffectants for
waste inffected by virus B.
