Advances in Floating Solar Desalination Systems

open access: yesWater and Environment Journal, EarlyView.
This review critically classifies floating solar desalination systems into five main categories and compares their thermal performance, productivity and technological limitations. Membrane‐based and multieffect systems showed the highest efficiencies, while traditional designs remain limited by heat losses and scaling.

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

open access: yesExperimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Characterization of a two‐phase hybrid flotation column

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3758-3774, July 2026.
Abstract This study explored the performance of a novel hybrid flotation column, which combines the advantages of a mechanically agitated cell with a flotation column and compared the results with a conventional flotation column setup. The experiments were performed in an air/water two‐phase system under varying airflow rates, frother concentrations ...

Microplastics and nanoplastics in water: Improving removal in wastewater treatment plants with alternative coagulants

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3744-3757, July 2026.
The contaminant removal performance of a conventional coagulant, alum, and alternative coagulants, aluminium chlorohydrate (ACH) and ACH + pDADMC, are compared in challenging wastewater treatment conditions (pH >7.8). The interactions of each coagulant with a negatively charged surface are depicted based on quartz crystal microbalance with dissipation ...

Role of froth processes on flotation

open access: yes, 1994
The importance of various froth processes on the performance of flotation cells has been long before recognized. The froth and its stability, the entrainment and the drainage of particles are important factors which affect the grade of the product and ...

Optimising froth stability of copper flotation tailings [PDF]

open access: yes, 2018
Linking results from laboratory scale experiments to industrial flotation behaviour is challenging. Typically, such experiments involve batch tests in which the system does not operate at steady-state, making it difficult to infer the effects that ...
