Harvesting of microalgae botryococcus sp. Through phycoremediation of bathroom greywater
… and one of the causes is direct discharge of greywater into the drains. Therefore, phycoremediation of greywater especially from bathroom sources with microalgae is proposed. The objectives of this research are to measure the efficiency of Botryococcus sp. in assimilating pollutant load, to …

The effects of greywater irrigation on vegetable crops and soil
Research on greywater irrigation has mainly focused attention on the reuse of greywater in relation to its quality and crop biomass but not on quality of edible vegetable crops. Thus a field experiment was established at the Umtata Dam Research Station where combinations of cabbages and onions; …

Domestic greywater systems: a potential reservoir of antibiotic resistance genes transfer
… Cape drought from 2015 to 2018, the use of greywater to alleviate pressure on the limited potable water available in the province was encouraged. Greywater, however, has the potential to harbour residual antibiotics and pathogenic bacteria, thereby potentially supporting the growth and …

Development and Evaluation of a Hybrid Membrane Bioreactor for Greywater Reclamation
… of the 21st century. To address this concern, a greywater reclamation system for non-potable water applications was developed and evaluated during this research. The reclamation system consisted primarily of a hybrid membrane bioreactor (HMBR), a biological treatment system containing both …

Phycoremediation of artificial bathroom greywater in village houses using microalgae botryococcus sp.
… waste. Direct discharge of household bathroom greywater into drains cause euthrophication into the water bodies. Phycoremediation of bathroom greywater effluent to meet a certain level of discharge limit using microalgae Botryococcus sp. is suggested. The objectives of this study is to asses …

Assessment of the effects of greywater discharge by using streeter-phelps model
Greywater is generated from household activities in bathroom, kitchen and laundry. Pollution of wastewater occurs when the greywater is discharged directly into the stream from the houses and accumulates in the drain. The organic pollutants and suspended particulate matter from greywater may cause …
