Local utilities often face problems of local industrial wastes, storm water disposal due to existing strict regulations. For many local industries, the problem of wastewater treatment and discharge into surface reservoirs can’t be solved through the use of conventional biological treatment techniques. Current discharge standards require very strict removal of a number of impurities such as ammo...

Wastewater treatment for removal of organic matter, inorganic matter and heavy metals is becoming increasingly important area of research. The disposal of wastewater to sea and other reservoirs can cause serious environmental problems. Wastewater from petroleum and refineries contains organic matter in various forms. Biodegradable and nonbiodegradable pollutants call for different biological an...

The dairy industry has important to day-today in human life. Dairy industry involves processing of raw milk into products like milk, butter and cheese, etc., and generates 1 to 3 times the volume of milk produced. Knowledge on the physico-chemical characteristics of dairy wastewater is essential in the design, operation, collection and treatment as well as disposal facilities for the effective ...

China is one of the largest producers and users of brominated flame retardants (BFRs) in the world. This has led to ubiquitous environmental occurrence of the main BFRs commercially available in China, namely polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDs), and tetrabromobisphenol A (TBBPA). Wastewater from BFR manufacturing, manufacturing of BFR-based products, and e-wa...

A common approach to wastewater pretreatment in the food industry is the utilization of dissolved air flotation @AF) cells. DAF units are common for BOD, TSS, and FOG reduction when wastewater is discharged to a municipal wastewater treatment plant. A growing problem for all DAF systems is that of sludge disposal. In the o p t i o n of a DAF, contaminants are removed in the form of a concentrat...

Wastewater collection and treatment is quite important for sustainable management. It would be uneconomical and impractical to provide sewer systems and separate wastewater treatment plants (WWTP) for small communities. The decision process in wastewater planning is rather important in terms of comparing the alternatives considered. The two important points in the management of wastewater at ru...

Almost three years on from commissioning, the unique $30M domestic wastewater treatment approach developed by Hastings District Council (HDC) and consultants MWH has proven itself to be leading-edge, technically-robust, cost-effective and culturally-acceptable. An innovative “no sludge” solution was adopted that has resulted in a paradigm shift in wastewater planning and treatment in New Zealan...

Nitrogen and chlorophyll-a concentrations in estuarine systems often correlate positively with increased nitrogen input. To determine the interactions between nitrogen load, physical drivers, and water quality indicators, we estimated nitrogen inputs to 28 estuaries within the Buzzards Bay, Massachusetts (USA) watershed from 1985 to 2013. Estimates were derived by combining parcel specific wast...

When addressing urban water problems, it is no longer adequate to consider issues of water supply, demand, disposal, and reuse independently. Innovative water management strategies and opportunities for water reuse can only be properly evaluated in the context of their interactions with the broader water system. An integrated linear deterministic optimization model is applied to Beirut, Lebanon...

Mumbai, the financial capital of India is generating about 2700 MLD of sewage from seven service areas and discharging into adjoining coast, Malad, Mahim, Marve and Thane Creeks. The coastal and creeks water quality is deteriorating due to disposal of partially treated sewage, wastewater from open drains as well as industrial wastewater. The objective of present paper is to assess and evaluate ...
