Process design

This paper introduces a process synthesis strategy and optimization approach that accounts for boron removal considerations in Seawater Reverse Osmosis (SWRO) network design. The overall aim is to provide an improved understating of the performance of SWRO networks when specific requirements on boron

A process optimization method has been developed for the design of reverse osmosis (RO) processes. RO process configurations are systematically generated using a flexible superstructure and evaluated by economical (investment and operating costs), technical (energy requirement, water recovery rate)

A process is set up to treat ammonium nitrate wastewaters. It couples membrane electrolysis and electrodialysis. Membrane electrolysis regenerates nitric acid and ammonia while electrodialysis is suitable to extract a depleted stream from the salt circuit and to recycle a concentrated stream. The me

The use of diafiltration is now the state-of-the-art in the food and beverage, biotech and pharmaceutical industry. In this paper, the advantages and disadvantages of the most common process modes of diafiltration, batch and continuous, are discussed. Further, the new concept of counter-current diaf
