Global water shortage is placing an unprecedented pressure on water supplies. Treated wastewater is a valuable water resource, but its reuse for agricultural irrigation faces a roadblock: the public concern over the potential accumulation of contaminants of emerging concern (CECs) into human diet. In the present study, we measured the levels of 19 commonly occurring pharmaceutical and personal ...

In peri-urban areas in low-income countries, conventional centralized approaches to wastewater management have generally failed to address the needs of communities for the collection and disposal of domestic wastewater and faecal sludges from on-site sanitation. There are opportunities for implementing wastewater management systems based on a decentralized approach that may offer opportunities ...

Personal care products (PCPs) are among the most commonly detected compounds in surface water. PCPs have used large amount of metal and metal oxide nanoparticles (NPs). In the present study an attempt was made to study the bioaccumulation and biochemical constituents changes in gill tissues of a freshwater fish labeo rohita exposed to metal and metal oxide nanoparticles in domestic wastewater c...

Constructed wetland technology has been widely applied around the world to treat domestic wastewaters from the single family home to small communities. Constructed wetlands can be classified as either surface flow wetlands (similar to natural wetlands) or subsurface flow wetlands, where the wastewater flows through a media. Subsurface flow constructed wetlands can either be horizontal flow syst...

Toxic chemical nature of tannery wastewater makes it difficult to be treated by routine biological treatment processes. Microbes, already present in tannery wastewater can adapt to these conditions and degrade the organics in tannery wastewater. In the present contribution, three bacterial electrogenic strains, tolerant to tannery environment, were isolated from soil contaminated with tannery w...

Phytoremediation offers a cost-effective, non-intrusive, and safe alternative to conventional cleanup techniques. In this study, we used ornamental hydrophytes plants as constructed wetlands to treat urban or rural domestic wastewater. Most ornamental hydrophytes adapted to the wastewater well, and were fairly efficient in scavenging BOD5 (biological oxygen demand 5 d), COD (chemical oxygen dem...

Dissolved organic nitrogen (DON) derived from wastewater effluent can participate in reactions that lead to formation of nitrogenous chlorination by-products, membrane fouling, eutrophication, and nitrification issues, so management of DON is important for both wastewater reuse applications and nutrient-sensitive watersheds that receive discharges from treated wastewater. This study documents D...

The emerging contaminants (ECs) is detected at trace concentration in the discharge of sewage treatment plant (STP) to water bodies indicate incomplete removal during process. presence ECs has a potential impact on ecological and human health associated with long-term ingestion mixture compounds, this includes development resistance pathogenic bacteria, aquatic toxicity, genotoxicity, endocrine...
