Integrating anaerobic acidification with two-stage forward osmosis concentration for simultaneously recovering organic matter, nitrogen and phosphorus from municipal wastewater.

In order to meet the demand of municipal wastewater for low-carbon treatment and resource recovery, a novel process of anaerobic acidification membrane bioreactor (AAMBR) assisted with a two-stage forward osmosis (FO) (FO-AAMBR-FO) was developed for simultaneously recovering organic matter and nutrients from municipal wastewater. The results indicated that the first FO process concentrated the municipal wastewater to one tenth of the initial volume. The corresponding chemical oxygen demand (COD), ammonia nitrogen (NH-N) and total phosphorus (TP) concentration reached up to 2800, 200 and 33 mg/L, respectively.

Exposure Route of TiO NPs from Industrial Applications to Wastewater Treatment and Their Impacts on the Agro-Environment.

The tremendous increase in the production and consumption of titanium dioxide (TiO) nanoparticles (NPs) in numerous industrial products and applications has augmented the need to understand their role in wastewater treatment technologies. Likewise, the deleterious effects of wastewater on the environment and natural resources have compelled researchers to find out most suitable, economical and environment friendly approaches for its treatment. In this context, the use of TiO NPs as the representative of photocatalytic technology for industrial wastewater treatment is coming to the horizon.
