Sequential batch reactor (SBR) process is basically a fill-and-draw activated sludge process. Being a very popular technology, SBR was not being frequently used for the treatment of wastewater like activated sludge process (ASP). This paper reviews two case studies, where SBR was used for capacity expansion of existing and ASP was converted to SBR.

Dairy industry generate large amount of white highly turbid liquid waste products which cannot be processed further in the industry and has to be discarded. They contain very high organic matter that may be in dissolved or colloidal form and is thus very high in BOD and total solids.

East Calcutta Wetland (ECW) is an example of wise use of cities solid and liquid waste through integrated resource recovery, mainly for pisciculture, vegetable as well as paddy cultivation and manure production. Amaranthus caudatus, Amaranthus blithum and Spinacia oleracea grown at ECW were analyzed for their accumulation of elements using Energy Dispersive X Ray Fluorescence (EDXRF) and compared to those grown in south eastern parts of West Bengal (Midnapur).

The textile sector has a high water demand. Its biggest impact on the environment is related to primary water consumption (80

The present study deals with physico-chemical analysis, treatment and utilization of Deoband sugar mill effluent. The effluent is treated with alkaline solution of hexacyanoferrate (III). 2007

A pot experiment was conducted during rabi season of 2003-2004, to study the effect of two concentrations of city waste water over ground water on the performance of Brassica juncea cv. Varuna. 2007

Industrialists and regulators are unclear on best practices in India's wastewater management in the textile sector, which generates 1,750 million litres a day (mld). Says Mangilal Gandhi, owner of

A split plot field experiment was conducted to study the comparative effect of sewage wastewater and ground water and of six doses of basal nitrogen on the performance of triticale. Sewage wastewater irrigation resulted in increased growth and yield of the crop. Protein and carbohydrate yields were also increased under wastewater irrigation.

This manual is a comprehensive documentation of localised community-level approaches in urban wastewater management. Besides providing an overview of eco-sanitation and decentralised wastewater treatment technologies, it also captures the emerging trends in this sector.

The sugar industry is an important and growing part of China, in general, and of Guangxi province, in particular. This growth poses scientific and engineering challenges for dealing with the environmental impacts of the industry.
