It is known that grey water reused for non-potable purposes, provides a sustainable solution of water management by reduction of fresh water extraction and can contribute to water status improvement. Although reused grey water is not intended for potable use, the potential for certain contamination and pollution rate still exist and the treatment efficiency represents a key concern for grey water system utilization. Therefore, this paper explores and focuses on treatment efficiency of treatment technology specifically on submerged membrane bioreactor, what is considered as a successfully used technique of grey water treatment. The main aim was to evaluate the pollution removal in variously polluted grey water and consider a treatability of purposed technology, while changing the grey water retention time in bioreactor.
