(2026) Application of 3D technologies on a pilot-scale single slope active solar still for two-phase olive mill waste dewatering: performance and preliminary modelling. Thermal Science and Engineering Progress, 75, 104771

Highlights
•An active SSD incorporating 3D technologies was tested for two-phase OMW dewatering.
•The use of cotton cloth, cotton wicks and clay solid bricks was evaluated.
•The use of clay bricks enhanced the exergy efficiency of the SSD, water recovery.
•High calorific value and bioactive compounds found in solid residual of the process.
•Sufficient prediction of TPOMW temperature and distillate production via modelling
