Design, construction and evaluation of an ablution water treatment unit in Oman: a case study

Overcoming constraints in treated greywater reuse in Oman

“…Considering the data reported by Jamrah et al [2], Prathapar et al [3] and Ahmed et al [1], and comparing with Omani standards for treated wastewater reuse, it is reasonable to conclude that greywater quality in Oman varies among sources, and with time, and it has to be treated before reuse.…”

“…Worshippers wash before each prayer and most mosques have ablution rooms with separate plumbing to drain water separately from blackwater. Prathapar et al [3] studied variations in quality and quantity of greywater produced at two mosques in Oman. Their results were based on 25 weeks of data beginning in October 2003.…”

“…Prathapar et al [3] analyzed ablution water samples from mosques for pH, electrical conductivity, turbidity, dissolved oxygen, BOD 5 , COD, coliforms, E. coli, total suspended solids, total dissolved solids and total carbon. Table 3 shows the results compared with wastewater reuse guidelines in Oman.…”

“…However until recently, lack of data on this aspect has been a barrier to arriving at such a conclusion. Ahmed et al [1], Jamrah et al [2] and Prathapar et al [3] have recently collected relevant data, which reveals that there are several factors constraining treated greywater reuse in Oman. They are categorized as quantity, quality, financial, legal, social and institutional constraints in this paper.…”

Greywater recycling: treatment options and applications

“…Similarly, in Jordan, Bino 38 used a simple, low-cost and easy to build treatment system made of plastic barrels. In Oman, Prathapar et al 39 designed and tested a low-cost, lowmaintenance system based on activated carbon, sand filtration and disinfection for the treatment of ablution water in a mosque.…”
