From March to August 2014, ,experimental, plots of carrots and Swiss chard were irrigated with ,wastewater, that had been treated by the alternative ,wastewater, treatment regime. It was found that the alternative ,wastewater, treatment regime coupled with the constructed wetland and fishpond appeared to remove helminths completely.

to 4 liters of 0.lM nitric ,acid,. The concentrated solution was slowlyadded to 40to 45gallons ofeither deionized (DI) water or filtered well water. Pretreatment chemicals were added and the solution neutralized to pH--7.5with 1.0M or 4.0M NaOH. Bacteria were added (before or after ,neutralization, as desired), and the ,filtration, process started.

Over 12 h of continuous operation shows consistent removal of ∼200 ppb HgS NPs from ,wastewater, by UF membrane ,filtration,. While membrane fouling occurred, it was demonstrated that a water wash could recover the flux. Dissolved Hg 2+ from UF-filtered ,wastewater, was effectively removed by a CysM-PAA-PVDF membrane.
