Sewage sludge, with its high water content, consists of settled sewage solids. The solid content of most sewage sludges typically ranges from 1.2 to 4.5 percent. Dewatering sewage sludges is essential to reduce volume for easier handling, subsequent treatment, and safe disposal. Notably, the cost of sludge treatment and disposal accounts for nearly half of sewage treatment costs. In the past, cities used to load sludge on barges and dispose of it in the high seas, but strict maritime laws now prohibit such discharge. As a result, proper sludge treatment and safe disposal have become crucial for achieving sustainable development goals in sanitation.

The document is actually a manual of training programme on the same title given which was intended to be helpful to bring about changes in terms of knowledge, skill and attitude among the officials of DPHE to improve …

This publication aims to update the knowledge base concerning all aspects of arsenic contamination, with a particular focus on Bangladesh. Major issues, including hydrogeology, water and soil contamination, food safety, health implications, social consequences, as well as analytical aspects including the chemistry and fate of arsenic in the environment, are discussed extensively within the context of Bangladesh.

This textbook has been developed with proper balance of ‘software’ i.e., socio-cultural and economic aspects and ‘hardware’ i.e., technical aspects, and with special attention to gender issue, including experiences in Bangladesh.

The purpose of the risk assessment was to quantify the health risks associated with different arsenic mitigation options. In providing alternative water supplies, it is important to be aware that users may be exposed to other hazards such as pathogens. Risk substitution in arsenic mitigation should always… … …

A total of 301 delegates and guests from nine Country Delegations (Afghanistan, Bangladesh, Bhutan, India, Maldives, Myanmar, Nepal, Pakistan and Sri Lanka) and other local and international organisations, participated in […]

This publication is a compilation of papers presented at the BUET-UNU International symposium on Fate of Arsenic in the Environment. The papers broadly describe the fate of arsenic extracted through tubewell water and transported with surface water, its presence in water-soil-plant environment …

It is a collection of selected technical papers that were presented at the second International Conference on Bangladesh Environment and presents a snapshot of Bangladesh environment at the present time, as understood by the experts from all over the world.

The sources of water available in Bangladesh for development of alternative water supplies are groundwater, surface water and rain water. An estimated 29 million people, exposed to arsenic contamination in excess of 50 µg/L through 27% contaminated shallow tubewells and few production wells in urban …

This publication is an outcome of the International Workshop on Arsenic Mitigation in Bangladesh held in Dhaka. The workshop focused on some important technical issues regarding hydrogeological and health aspects of arsenic contamination and alternative water supply options …
