Effect of flow velocity and cell-pair thickness in electrodialysis (ED) is studied. The production cost includes pump energy, while the size system considered as an output variable. performance ED depends on three categories process parameters namely water quality data, stack configuration characteristic inside stack. design complex due to interrelation among variables so calculation chronology...

Abstract Monovalent selective electrodialysis (MSED) is a variant of conventional (ED) that employs ion exchange membranes to preferentially remove monovalent ions relative divalent ions. This process can be beneficial when the rich stream has potential applications. In agriculture, for example, in calcium and magnesium deemed crops decrease use fertilizers would otherwise need re-introduced so...

Abstract Electrodialysis (ED) desalination has been demonstrated to be more energy-efficient, provide higher-recovery, and lower-cost for producing drinking water from saline groundwater compared reverse osmosis. These benefits of ED could translate into cost-effective, renewable-powered solutions. However, the challenge using a variable power source (e.g. solar) with traditional steady-state o...

In acetic acid fermentation by Acetobacter aceti, the acetic acid produced inhibits the production of acetic acid by this microorganism. To alleviate this inhibitory effect, we developed an electrodialysis fermentation method such that acetic acid is continuously removed from the broth. The fermentation unit has a computerized system for the control of the pH and the concentration of ethanol in...

The separation membrane techniques in which an external electric field is applied as a driving force (such as electrodialysis, electro-electrodialysis, and membrane electrolysis) are shortly described and their application in environment protection is presented. Attention was focused on recovery of valuable chemicals from effluents and waste gases. Examples of new production methods that elimin...

A mathematical model has been developed which describes the mass transfer across monovalent-ionpermselective membranes as used in an electrodialysis cell. The mass transfer model is based on the StefanMaxwell transport equations. The latters are derived in the membrane phase with two unstirred layers on each side. Donnan equilibrium is used to describe the concentration and the potential discon...

Reinforcing and optimizing sustainable food production is an urgent contemporary issue. The depletion of natural mineral resources a key problem that addressed by recycling mined potassium phosphorus, nitrogen, whose depends on very high energy input. A closed-loop approach fertilizer use asserts the necessity for efficient management practices organic waste rich in minerals. Human-derived urin...

Liquid desiccant air conditioning (LDAC) is an emerging technology able to maintain optimal growing conditions in self-sustained greenhouses powered by solar energy. However, the regeneration of liquid (LD) a bottleneck LDAC. This study investigates six desalination technologies – membrane distillation (MD), reverse osmosis (RO), nanofiltration (NF), forward (FO), thermoresponsive (TR) solution...

Operating parameters and membrane characteristics strongly affect the performance of electrodialysis reversal systems. The most impactful factors are applied voltage, flow rate, temperature, initial feed composition, and ion exchange membrane characteristics; the pH of the feed also has an effect, although to a lesser extent. To determine more precisely how all of these factors impact performan...

The yeast Saccharomyces cerevisiae is a potential candidate for converting waste resources into food-grade single cell protein (SCP). Food fermentation broth rich in lactic acid was tested as an alternative substrate source S. this study. An electrodialysis (ED) system developed to recover lactate, acetate and ammonium ions (La-, Ac- NH4+) from the broth. First, we evaluated resilience under va...
