Increasing Demand

Given the increasing demand pressure on water resources coupled with supply holdups and institutional failures, fresh-water resources are increasingly susceptible to depletion and could potentially add to water stress in India. A vast demand-supply gap necessitates water conservation, including recycling measures. India has a great potential in wastewater treatment, and one of the ways to address it is decentralisation of wastewater treatment given its environmental benefits. Based on the Contingent Valuation Method (CVM), this study assesses Delhi urban households’ willingness to pay for the Operation & Maintenance (O&M) costs of a local Wastewater Treatment Plants (WWTP) that supplies residential complexes treated water for toilet-flushing. The study found that if freshwater prices rise sufficiently for consumers, they may be willing to subsidise a decentralized WWTP to cover at least their non-potable water uses. In addition, the co-provision of such public goods can become an important supplement to urban municipal finance.

Treatment Technologies

The quality of freshwater and its supply, particularly for domestic and industrial purposes are waning due to urbanization and inefficient conventional wastewater treatment (WWT) processes. For decades, conventional WWT processes have succeeded to some extent in treating effluents to meet standard discharge requirements. However, improvements in WWT are necessary to render treated wastewater for re-use in the industrial, agricultural, and domestic sectors. Three emerging technologies including membrane technology, microbial fuel cells and microalgae, as well as WWT strategies are discussed in this chapter. These applications are a promising alternative for manifold WWT processes and distribution systems in mitigating contaminants to meet acceptable limitations. The basic principles, types and applications, merits, and demerits of the aforementioned technologies are addressed in relation to their current limitations and future research needs. The development in WWT blueprints will augment the application of these emerging technologies for sustainable management and water conservation, with re-use strategies.

Abstract The palm oil industry is one of the major agro-industries in Southern Thailand. It requires a large amount of water for its operation and discharges considerable quantities of wastewater. This creates a serious threat to the environment and sources of potable water. This study proposes recommendations for water conservation and reuse and improvement of wastewater treatment facilities to overcome these problems. In order to attain the highest reduction of all problems, waste minimization is introduced as the most effective solution. Changing behaviour in housekeeping can reduce water usage. An upflow anaerobic sludge blanket (UASB) process coupled with an activated sludge plant is recommended to upgrade the wastewater treatment system. For water reuse purposes, a rock bed filtration unit is recommended to treat effluent of the treatment plant. The overall water balance of the palm oil mill suggests that water reuse of 322 m3/d will reduce raw water consumption by 27.66% and achieve a 23% reduction in the water discharged to the river.

Some components of the wastewater management systems used in northern Canada have undergone significant changes within the last ten years. The natural and imposed constraints are reviewed with special emphasis on the wastewater characteristics. Wastewater collection through the use of butt-welded polyethylene pipe, individual line service connections, and truck collection are discussed. Improvements in the disposal of undiluted and moderately, conventionally, and greatly diluted wastewater are outlined. The problems and improvements underway with greywater treatment and disposal are important for the improvement of living conditions. Also, current efforts to increase water conservation are noted. Keywords: cold regions engineering, wastewater treatment, sewage collection, sewage disposal, water conservation.

Positive Effect

We recently developed an autotrophic biofloc technology (ABFT) system entailing simultaneous microalgae co-culturing with juvenile-farming-stage fish and shrimp in aquaculture and microalgae-based water treatment. The present study was conducted to confirm the potentialities of the ABFT system at the remaining stages (seedling to adult farming, Nile tilapia) for industrial-level implementation. In the results at the seedling stage, an excellent water-purification effect and significant water conservation (97% reduction) by microalgae were verified. Indeed, among the fish, there were not any significant differences, either in growth performance or in body composition, and the wastewater from this system was recycled by use for the growth of various plants. Further, the ABFT system was demonstrated to have a positive effect on production economics by simplifying the production process steps (simultaneous fish breeding and wastewater treatment) and providing for a natural hatching environment. In summary, the ABFT system can be integrated with existing systems on an industrial level as an effective and efficient means of achieving sustainable aquaculture.
