  2. Zero liquid discharge - Wikipedia

    en.wikipedia.org/wiki/Zero_Liquid_Discharge

    Zero Liquid Discharge (ZLD) is a classification of water treatment processes intended to reduce wastewater efficiently and produce clean water that is suitable for reuse (e.g., irrigation). ZLD systems employ wastewater treatment technologies and desalination to purify and recycle virtually all wastewater received.

  3. Industrial wastewater treatment - Wikipedia

    en.wikipedia.org/wiki/Industrial_wastewater...

    In the recent years, there has been greater prevalence in brine management due to global push for zero liquid discharge (ZLD)/minimal liquid discharge (MLD). [48] In ZLD/MLD techniques, a closed water cycle is used to minimize water discharges from a system for water reuse. This concept has been gaining traction in recent years, due to ...

  4. Low-temperature distillation - Wikipedia

    en.wikipedia.org/wiki/Low-temperature_distillation

    Direct spray distillation is a water treatment process applied in seawater desalination and industrial wastewater treatment, brine and concentrate treatment as well as zero liquid discharge systems. It is a physical water separation process driven by thermal energy. Direct spray distillation involves evaporation and condensation on water ...

  5. Thermodynamic databases for pure substances - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_databases...

    The values are organized in a format that makes them readable by a thermodynamic calculation program or for use in a spreadsheet. For example, the Excel-based thermodynamic database FREED creates the following type of datafile, here for a standard pressure of 1 atm. Thermodynamic datafile for MgCl 2 (c,l,g) from FREED. Some values have ...

  6. Discharge coefficient - Wikipedia

    en.wikipedia.org/wiki/Discharge_coefficient

    In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, [1] i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures.

  7. Stiff diagram - Wikipedia

    en.wikipedia.org/wiki/Stiff_diagram

    Stiff diagrams can be used: 1) to help visualize ionically related waters from which a flow path can be determined, or; 2) if the flow path is known, to show how the ionic composition of a water body changes over space and/or time. Example of a Stiff diagram. A typical Stiff diagram is shown in the figure (right).

  8. Isentropic nozzle flow - Wikipedia

    en.wikipedia.org/wiki/Isentropic_Nozzle_Flow

    Enthalpy-Entropy diagram of stagnation state. In fluid dynamics, a stagnation point is a point in a flow field where the local velocity of the fluid is zero. The isentropic stagnation state is the state a flowing fluid would attain if it underwent a reversible adiabatic deceleration to zero velocity.

  9. Critical point (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Critical_point...

    The liquidliquid critical point of a solution, which occurs at the critical solution temperature, occurs at the limit of the two-phase region of the phase diagram. In other words, it is the point at which an infinitesimal change in some thermodynamic variable (such as temperature or pressure) leads to separation of the mixture into two ...
