A system involving a granular activated carbon (GAC) biofilm up-flow expanded bed (UEB) reactor and a slow down-flow packed sand filter was established for treating mosque grey water (ablution water).The faecal coliforms (FC),chemical oxygen demand (COD),total suspended solids (TSS),nitrate (NO 3),and ammonia as nitrogen (NH 4-N) were investigated under continuous flow operation using a hydraulic retention time (HRT) ranging from 1-6 hr over the period from 5/9/2010 to 6/2/*** system was arranged so that the GAC reactor is the first stage of treatment,and the sand filter is the second *** and effluent samples from the system were analysed *** system demonstrated satisfactory removal of faecal coliforms with removal efficiencies of 63-80 %,and the efficiencies of COD and TSS removal were 70 % and 72 %,*** system showed low removal efficiencies of nitrate which was 0-13 %.No ammonia removal was recorded in that range of retention time,while the system showed approximately 50 % removal efficiency on average for 12 hr of HRT.

BACKGROUND Recently,there have been several findings that showed intestinal colonisation of Blastocystis hominis(Blastocystis)as a risk factor to the worsening of colorectal cancer(CRC).However,studies have shown controversial results in the pathogenicity of *** To review systematically the evidence available on the association between CRC and Blastocystis and the prevalence of Blastocystis in CRC patients and to investigate cytopathic and immunological effects of Blastocystis in in vitro and in vivo *** PRISMA guidelines were utilised in conducting this systematic *** articles published before February 2,2020 were ***,Science Direct,Scopus and Google scholar databases were *** searching was carried out to find articles missed during the online *** Out of 12 studies selected for this systematic review,seven studies confirmed the prevalence of Blastocystis and found it to be between 2%-28%in CRC patients,whereby subtype 1 and subtype 3 were predominantly seen.A total of four studies employing in vitro human colorectal carcinoma cell line study models showed significant cytopathic and immunological effects of *** addition,one in vivo experimental animal model study showed that there was a significant effect of infection with Blastocystis on exacerbation of colorectal *** Blastocystis is a commonly identified microorganism in CRC *** studies have provided supportive data that Blastocystis could exacerbate existing CRC via alteration in host immune response and increased oxidative *** studies of CRC and Blastocystis should attempt to determine the various stages of CRC that are most likely to be associated with Blastocystis and its relationship with other intestinal bacteria.
