  • What Is Zero Liquid Discharge and How Does It Work?

    Not every industrial facility that produces wastewater will require zero liquid discharge (ZLD). It is usually looked to as a last resort because it can be a complex process that requires a high initial investment. If a facility is located on a site that has severe water scarcity issues and/or astronomical discharge fees, it might be ...

  • Hybrid gas-liquid electrical discharge for degradation of organic pollutants in aqueous solution

    Hybrid gas-liquid electrical discharge for degradation of phenol was investigated. The removal rate increased with decreasing the phenol initial concentration and adding some catalysts, such as Fe2+, Fe3+and H2O2. Augmenting the particle diameter of activated alumina or exchanging beadings as padding would lead to the reduction of the removal rate of phenol. Local discharge promoted the phenol ...
