Contamination, Pollution and Quality

About CAT “MAR” (Multi Stage Aerobic Bio Reactor)

This reactor was developed with the aim to overcome the main problem associated with SBR, MBR & FABBR, i.e.,

• The plugging & clogging of filter and
• Wash out microbes from the reactor        

The historic UN General Assembly Resolution declaring Water and Sanitation as a Right, was passed on the 28th July 2010. 

What is surprising is the complete silence to this UN Resolution from some of the countries who have been traditional champions of human rights, in terms of celebrating it as a historic achievement in advocating a basic right to water and sanitation. Instead some of them went one step short of openly opposing and vetoing the UN Resolution and have heaped criticism on Bolivia for tabling this UN Resolution.

Sanitation - a big problem in India, as half the population of our country do not have access to this facility. Mumbai is one of the biggest cities in the world and advanced in terms of its commercialization. However, sanitation is one of the most common issues neglected. Our team of women from Jan Jagruti went into the lanes of 3 areas Azad Mohala, Bharatiya Kamla Nagar, Vijay Nagar and spoke to women to understand the severity of the sanitation issue prevailing. These areas have severe problems with public health, due to improper sanitation infrastructure and insufficiency of toilet facilities, compounded by numerous issues of flooding during the monsoon season. Khaaddi, a local area/dumping ground, is widely used by local residents for urination and defecation, leading to the spread of contagious diseases. Though women use paid toilets, the issue of cleanliness and waiting in long queues are the most common problem before them. It is very insecure for them when they use open spaces for defecation.

This Civil Engineering Course under the National Programme on Technology Enhanced Learning (NPTEL) on the broad subject of Water Resources Engineering and Management is being carried out by Indian Institute of Technology’s and the Indian Institute of Science, Bangalore as a collaborative project supported by the Ministry of Human Resource Development (Government of India) to enhance the quality of engineering education in the country, by developing curriculum based video and web courses. In these web based lectures, the authors have developed the subject in detail and in stages in a student-friendly manner. The broad group of Water Resources Engineering is structured into modules on the topic by IIT Kharagpur as follows:
