Environmental Protection & New Energy

Introduction

New energy manufacturing and environmental water treatment involve liquids with different filtration requirements. Battery slurries and material-processing streams may require control of oversized particles, agglomerates, suspended contaminants, and ferrous particles. Photovoltaic facilities, cooling-water systems, and water-reuse processes may require sediment removal, turbidity reduction, and membrane protection. Fengnuochang provides industrial filtration and water-treatment equipment selected according to the liquid, solids loading, viscosity, flow rate, target micron rating, operating conditions, and downstream requirements.

FILTRATION EQUIPMENT FOR NEW ENERGY & ENVIRONMENTAL APPLICATIONS
