As various technologies are used for water and wastewater treatment, a global strategy with the objective of comparing and containing the price of water in the future is required. A study was carried out for this reason on production cost component of the price of water. This paper extends the concept of previously reported Water Price Index (WPI) as a metric for the cost of water production that can be adapted to water and wastewater treatment plants to evaluate their performance. Equations that define the contribution of capital and operational expenditure to the WPI are presented. Case studies from Eraring Power Station, Marquette Water Filtration Plant, Perth Desalination II and a theoretically modelled plant demonstrated the applicability of WPI and the benefit it brings to water practitioners.

“…Different strategies can be followed to improve the performance of the system in terms of water production capability, output power, and energy efficiency. The energy consumption in RO or MD can be reduced by controlling the operating conditions, using appropriate pre-treatment techniques, and designing optimal membranes and modules [12,21]. The potential and hence the output power from a RED unit can be improved by the development and use of highly permeable and low resistance IEMs (ion exchange membranes) [11].…”

Membrane Operations for Process Intensification in Desalination

Process intensification strategy (PIS) is emerging as an interesting guideline to revolutionize process industry in terms of improved efficiency and sustainability. Membrane engineering has appeared as a strong candidate to implement PIS. The most significant progress has been observed in desalination where substantial reduction in overall energy demand, environmental footprint, and process hazards has already been accomplished. Recent developments in membrane engineering are shaping the desalination industry into raw materials and energy production where fresh water will be produced as a byproduct. The present study discusses the current and perspective role of membrane engineering in achieving the objectives of PIS in the field of desalination.

“…As a result, the decline in fouling, especially through the development of chlorine-tolerant membranes, is crucial since it reduces the costs of membrane replacement, backwashing chemicals, and energy needed to overcome the additional osmotic pressure. The operating pressure in many of the current systems is already nearing the thermodynamic limit and an additional reduction would have a relatively modest efect on the overall performance [44]. Nonetheless, a decrease in energy consumption would be substantial, as the energy costs signify half of the total water production costs.…”

Biomimetic and Bioinspired Membranes for New Frontiers in Sustainable Water Treatment Technology

As water scarcity continues expanding in regions around the globe, there is an everincreasing need to augment municipal, industrial, and agricultural water supplies through the puriication of unconventional water sources, such as seawater, industrial and municipal wastewater. Due to the inextricable linkage between water and energy consumption, often called the water-energy nexus, the augmentation of water supplies must not come with a high cost energy consumption. As such, the high energy eiciency and often superior eicacy of membrane-based technologies have gained widespread implementation in various water treatment processes. Membranes allow passage of water, but largely reject salt and most other solutes, play a critical role in the majority of these processes. These types of membranes lie at the heart of traditional reverse osmosis (RO) processes.
