  • 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 ...

  • Case Study - Zero Liquid Discharge (ZLD) Application

    Applied Water Solutions was contacted by a client who planned to move their manufacturing facility to an area where there is strict limitations on water discharge. Working close with the client we created a process flow diagram (PFD) using multiple water purification technologies that provided pure water generation, water recycling capabilities and offsite disposal of solids. From the PFD we then ...

  • Corrugated Printing Facility Zero Discharge

    This company imports corrugated board and prints the labels using a flexographic machine. The facility had a wastewater treatment system using the traditional liquid chemistry of aluminum chloride, caustic for pH adjustment, and an anionic flocculant. The effluent was often out of compliance due copper from the color pigments in the inks. The system required continual adjustment of the 3 ...

  • How much will a zero liquid discharge system cost your facility?

    With increasing stewardship of environmental protection, both nationally and internationally, many industrial facilities and effluent regulators are strengthening strategies to reduce industrial process waste by implementing zero liquid discharge (ZLD), a process that limits liquid waste at the end of your industrial process to—as the term suggests—zero. A ...

  • 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 ...

  • Dielectric barrier discharge induced degradation of diclofenac in aqueous solution

    A dielectric barrier discharge (DBD) reactor as one of the advanced oxidation processes was applied to the degradation of diclofenac in aqueous solution. The various parameters that affect the degradation of diclofenac and the proposed evolutionary process were investigated. The results indicated that the inner concentrations of 10 mg/L diclofenac can be all removed within 10 min under ...

  • Purification of inkjet ink from water using liquid phase, electric discharge polymerization and cellulosic membrane filtration

    A method to separate inkjet ink from water was developed using a liquid phase, electric discharge process. The liquid phase, electric discharge process with filtration or sedimentation was shown to remove 97% of inkjet ink from solutions containing between 0.1–0.8 g/L and was consistent over a range of treatment conditions. Additionally, particle size analysis of treated allyl ...
