QUANTIFICATION AND CHARACTERIZATION OF GREY WATER GENERATED FROM MOSQUES: A CASE STUDY OF POLICE COLONY MOSQUE PESHAWAR

Abstract

Grey water generated from different sources especially from mosque is mainly focus in this research paper. Salat is one of
Key pillar of Islam and Muslims are obligated to pray it five times a day. In order to pray prayer Muslims do ablution in
which they washes their feet, face and hands to make them clean and prepare for offering prayer. The quantity of water used
for this purpose is high as compared to be used in other hygienic activities. Therefore to make the water reusable it is
necessary to investigate the water used during ablution times. For the purpose of investigation the ablution water, first we
have to find its characteristics and quantity (how much water generated as grey water) and to assess its suitability for
different purposes, such as for irrigation, gardening’s and flushing toilets.
Filtration units is designed and constructed for collection of Grey water use during ablution. Digital flow meters along with
Arduino data acquisition system is use for measurement of water usage during ablution process. Physical, chemical and
biological samples were collected before and after the treatment while calculation of water consumption was done as
average per capita. To assess the social attributes toward usage of grey water, questionnaire was developed. The results of
tests conducted showed that the suspended solids was found 175mg/L in raw grey water while after filtration it was reduced
to 79mg/L.
