Synthesis of Heat-Integrated Water Networks: Case Study with Sensitivity Analysis

Chemical Engineering Transactions, 2021
This work addresses the synthesis of heat-integrated water networks (HIWNs) by using a superstructure optimisation approach. A recently developed mixed-integer nonlinear programming (MINLP) model and an iterative solution strategy are applied in this ...

Comparison of the phytoplankton community compositions between the temperate reservoir and the downstream river areas of the Han River, Korea

Journal of Freshwater Ecology, 2023
Phytoplankton communities serve as useful bioindicators of environmental changes in aquatic ecosystems and can be used to assess the health of freshwater systems. Their community composition responds sensitively to changes in habitat conditions.

Application of microalgae Scenedesmus acuminatus enhances water quality in rice-crayfish culture

Frontiers in Bioengineering and Biotechnology, 2023
Improper management of aquatic environments substantially restricts the development of the aquaculture industry. The industrialisation of the crayfish Procambarus clarkii, for example, is currently being limited by poor water quality.
