ABSTRACT Anthropic changes in coastal watersheds affect the quantity and quality of water estuaries. Based on an analytical model saline intrusion load balance, we have evaluated effects effluent discharge (mean 285 L·s−1 peak 495 L·s−1) from a wastewater treatment plant (WWTP) island estuary. Saline at low tide, without actual anthropic discharge, will increase by 22%, whereas with increasing ...

This paper reported the pollutant removal performances of a hybrid wetland system for the treatment of aquaculture wastewater. The system consisted of two treatment stages: a subsurface vertical flow (VF) wetland, followed by a horizontal flow (HF). The aquaculture wastewater with the different concentrations such as eutrophy and mesotrophy was treated using hybrid constructed wetland. The expe...

In many regions of the world, urban water systems will need to transition into fundamentally different forms to address current stressors and meet impending challenges-faster innovation will need to be part of these transitions. To assess the innovation deficit in urban water organizations and to identify means for supporting innovation, we surveyed wastewater utility managers in California. Ou...

Irrigation with wastewaters from agri-industry processes such as milk factories, piggeries, wineries and abattoirs is commonplace. These wastewaters all have high levels of potassium (K). Potassium concentration in effluents from domestic wastewater sources are relatively low, reported to vary between 10 and 30 mg L(-1). Higher levels of potassium are reported for effluents from olive oil mills...

This study investigated the performance and microbiome of cyclic denitrification filters (CDFs) for wood sulfur heterotrophic-autotrophic (WSHAD) saline wastewater. Wood-sulfur CDFs integrated into two pilot-scale marine recirculating aquaculture systems achieved high rates (103 ± 8.5 g N/(m3·d)). The combined use pine resulted in lower SO42? accumulation compared with prior wastewater studies ...
