Conference Paper
Full-text available
In a developing country like India where 68.84% people live in villages with insufficient sanitation and a poor infrastructure for waterborne sanitation. Government institutions, private water agencies and research institutes are engaged in exploring all alternative domestic wastewater treatment options at the onsite level. Integrated settler based...
Chapter
This chapter deals with the long-term performance of a filter-based sanitation system, under the actual field conditions, to identify its feasibility as a package plant for on-site treatment of domestic wastewater generated by household activities. The study is aimed at designing a more efficient and low-cost sanitation system as a replacement for...

Membrane Bio Reactor (MBR) system, designed to achieve high quality effluent within a small overall footprint. The MBR process utilises the well proven activated sludge process, but replaces conventional final settlement with an ultrafine membrane which effectively filters the final effluent. Membrane bioreactors (MBRs) can be broadly defined as sy...
Article
Carbon to nitrogen ratio (C/N) is not the lone limiting factors in biological nutrient removal from municipal wastewaters, but readily biodegradable to slowly biodegradable COD ratio (rbCOD/sbCOD) inter alia governs the process of nutrient removal. An intermittent aeration pre-anoxic sequencing batch reactor was operated at C/N ratio of 3, 7.5, and...

Air pollution is a worldwide environmental issue and generates different types of health problem, especially in major developing countries. Firstly, we affect the environment and then environment effect to us (in short-term smog and long-term global warming, climate change…). A recent World Health Organization report shows 3 million deaths in the w...
Article
Sludge reduction by physico-chemical methods results in the buildup of chemicals, which may require further treatment. Owing these reasons various biologically sustainable methods of sludge reduction including the application of high oxygenation have been successfully tested. Experiments on actual sewage in two lab-scale sequencing batch reactors (...
Article
On-site treatment of black water generated at a residential school was investigated by employing an upgraded two-stage package system: a modified septic tank followed by an anaerobic filter. The findings revealed that the average removal efficiency for CODtot, CODss, BOD and TSS were 72.6, 90.2, 78.4 and 83.2%, respectively. Monthly septage charact...
Article
An investigation was done on the process kinetics of a two-stage (modified septic tank plus anaerobic filter) anaerobic bioreactor while treating actual domestic wastewater. The individual values of second-order substrate removal rate constant (k) for septic tank and anaerobic filter were observed as 0.36 and 0.26 per day, respectively. It was 0.49...
Article
The present study evaluated the performance of a uniquely configured compact anaerobic packaged system as an alternative to the conventional septic tank for a single household. The system consisted of two bioreactors, a septic tank followed by an upflow anaerobic filter. Both reactors were accommodated within a single compact unit. The treatment ef...
Article
The present study investigates the efficiency and feasibility of an anaerobic packaged system for onsite treatment of source-separated black water from a residential school. The system consisted of a modified septic tank followed by an upflow anaerobic filter, both accommodated within a single unit. The present system achieved comparatively much hi...
Article
Full-text available
A laboratory-scale study was carried out to investigate the effects of physical properties of the supporting media and variable hydraulic shock loads on the hydraulic characteristics of an advanced onsite wastewater treatment system. The system consisted of two upflow anaerobic reactors (a septic tank and an anaerobic filter) accommodated within a...
Article
Full-text available
A strong focus on increasing gross domestic product to meet demanding needs stretched the country on the brink of overstretching the ecological carrying capacity. Unfortunately, rivers are among the worst affected natural resource. The government of India thus initiated the Ganga and Yamuna action plans and spends around 20 billion rupees against t...
Article
Wastewater produced from all the domestic uses of water sans toilet flushing is known as greywater. It is often the major component in the domestic wastewater but has fewer pollutant load. Recycling and reuse of treated greywater for non-potable purposes may significantly reduce the stress on the fresh water requirement. This article presents the r...
Article
Full-text available
This study demonstrates the performance evaluation of a uniquely designed two-stage system for onsite treatment of domestic wastewater. The system consisted of two upflow anaerobic bioreactors, a modified septic tank followed by an upflow anaerobic filter, accommodated within a single cylindrical unit. The system was started up without inoculation...
