Impact of treated wastewater on plant growth: leaf fluorescence, reflectance, and biomass-based assessment.

The study evaluated the impact of treated wastewater on plant growth through the use of hyperspectral and fluorescence-based techniques coupled with classical biomass analyses, and assessed the potential of reusing treated wastewater for irrigation without fertilizer application. Cherry tomato () and cabbage ( L.) were irrigated with tap water (Tap), secondary effluent (SE), and membrane effluent (ME).

Treated wastewater reuse for irrigation: Pros and cons.

The appropriateness of using treated wastewater for crop or agricultural irrigation remains a bone of contention among experts and policymakers. Here, we outline and analyze not only the benefits but also the drawbacks of such a practice in order to suggest a way forward. To ensure that our review reflects the state-of-the-art in terms of technological advances and best practices, only literature published in the last decade is considered except for literature on the history of reuse.

Influence of phosphorus precipitation on permeability and soluble microbial product concentration in a membrane bioreactor.

Many articles have been published on coagulant dosing in membrane bioreactors, though few have been long-term studies examining the treatment of real wastewater. This study summarises the results of a membrane bioreactor pilot-plant (flat sheet membrane, nominal pore size 0.03 μm) that treated real municipal wastewater for two-years.

Operational experience with a seasonally operated full-scale membrane bioreactor plant.

A seasonally operated full-scale membrane bioreactor plant (flat sheet, 0.03 μm) treating municipal wastewater from a recreation facility was monitored for 2 years. In particular, membrane bioreactor operation characteristics and development and changes in extracellular polymeric substances and soluble microbial product concentrations were observed, which were both dependent on volume and quality of incoming wastewater.

The impact of different operating conditions on membrane fouling and EPS production.

The main goal of this research was to investigate how different factors influence membrane fouling. The impact of the different concentrations of activated sludge and the amount of extracellular polymer substances (EPS) were monitored. Two pilot plants with submerged membrane modules (hollow fiber and flat sheet) were operated and the raw wastewater was used.
