Development of evaporation technique for concentrating lead acid wastewater from the battery recycling plant, by nanocomposite ceramic substrates and solar/wind energy.

Wastewater from car battery recycling plants contains lead ions. This acidic wastewater was treated by the solar steam generation method. In this research, a light porous ceramic substrate (PCS) was made based on clay, human hair, and nano-hydroxyapatite.

Fabrication of 3D hydrogel to the treatment of moist air by solar/wind energy in a simulated battery recycle plant salon.

Contaminated air in battery recycling halls threatens the health of factory workers. In this work, a new 3D hydrogel was designed in a simulated salon with an innovative rotary module. The Pb(II), Fe(III) and SO was adsorbed from air.

Design and optimization of a new reactor based on biofilm-ceramic for industrial wastewater treatment.

A biofilm reactor was designed with flat ceramic substrates to remove Co(II), Ni(II) and Zn(II) from industrial wastewater. The ceramics were made of clay and nano-rubber with high mechanical resistance. The surface of the ceramic substrate was modified with neutral fiber and nano-hydroxyapatite.

A novel fixed-bed reactor design incorporating an electrospun PVA/chitosan nanofiber membrane.

In this research, a novel fixed-bed reactor was designed with a nanofiber membrane composed of a polyvinyl alcohol (PVA)/chitosan nanofiber blend prepared using an electrospinning technique. The applied voltage, tip-collector distance, and solution flow rate of the electrospinning process were 18 kV, 14.5 cm, and 0.
