Taking into account the worrying scenario of water scarcity, it is essential to enable more efficient technologies for wastewater treatment. Wastewater may be treated by conventional biological processes that remove pathogenic organisms, particulate and soluble organic compounds, other components. However, secondary effluents from treatment plants still contain toxic elements or high concentrat...

Wastewater samples collected from ten wastewater facilities across the US were analyzed to determine the occurrence of indigenous Cryptosporidium oocysts using methods based on modifications of USEPA Method 1622. Wastewater facilities participating in this study ranged in size from 0.6 to 193 mgd average daily flow. A total of 289 wastewater samples were analyzed over a 15-month period. ColorSe...

Enteric bacteria have been examined for their ability to transfer antibiotic resistance in a wastewater treatment plant. Resistant Salmonella enteritidis, Proteus mirabilis, and Escherichia coli were isolated from clinical specimens and primary sewage effluent. Resistance to ampicillin, chloramphenicol, streptomycin, sulfadiazine, and tetracycline was demonstrated by spread plate and tube dilut...

The vision of environmental engineering is wide, varied and unparalled. The changing world has prompted scientists to target towards green chemistry and green engineering. Green engineering encompasses environmental engineering. The path of success is visionary. Environmental engineering along with dye degradation techniques is ushering in a new era and new vision environmental pollution contro...

A large amount of effluent is generated in textile industries. Dyes used in the dyeing stage of a textile industry is a constant, ardent and keen source of concern to the environmental scientist. This dye effluent cannot be degraded through primary and secondary treatments. Primary treatment involves coagulation and flocculation while secondary treatment encompasses activated sludge process. So...

Persistent Organic Pollutants (POPs) are toxic, persistent, bioaccumulative and prone to long-range transport. In the environmental sectors, solids including soil and sediment are recognized as the ultimate ‘sink’ for accumulating POPs. In order to combat the threat posed by POPs to human health and the environment, research and development of technologies for removal of POPs from solids have g...

Pharmaceuticals and personal care products (PPCPs) represent pollutants of emerging concern, originating in surface and drinking waters largely from their persistence in wastewater effluent. Accordingly, a wealth of recent investigations has examined PPCP fate during wastewater treatment, focusing on their removal during conventional (e.g., activated sludge) and advanced (e.g., ozonation and me...
