Autochthonous Greywater Reuse System Scifair Projects

Objectives/Goals

The prospect of this investigation is to ascertain whether an autochthonous greywater reuse and filtration complex can minimize unfavorable indicators of water quality (e.g. alkalinity, pH) and yield surpassing height lengths and biomasses of basil plants compared to those of untreated greywater.

Methods/Materials

Greywater is salvaged from the washer and transported outdoors to be filtered through mechanical processes (including sand filtration). Treated greywater (experimental), untreated greywater (control) annexed before filtration, and tapwater will be measured for levels of water quality determinants and each water sample will be used to water 10 plants each to compare biomasses and height.

Results

Ocimum basilicum grown in treated greywater had height lengths and biomasses almost duplicate to those of tapwater, while plants watered in untreated greywater languished in root damage and lagging heights.

Conclusions/Discussion

Accordant results after ten trials manifest cogency of a small-scale, cost-efficient greywater treatment system and connote arbitration of greywater constrained to being filtered for the scope of watering plants. 3rd party contributor
