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.
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 ...
Additionally, water streams with very high salt concentrations, that cannot be separated by reverse osmosis, can be concentrated by electrodialysis up to concentrations near to saturation. This is very useful for Zero Liquid Discharge treatments, providing a reduction in energy consumption compared to evaporation.
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 ...
Zero liquid discharge (ZLD) is a water treatment process to eliminate liquid waste from industries that release very polluted wastewater, such as the fertiliser sector and distilleries.
The global airline industry will likely rake in more than $1 trillion in revenue next year, as passenger numbers look set to hit an all-time high of 5 billion, the International Air Transport ...
The advocacy group Earthjustice said the EPA's decision would mean cars in the state would largely be zero-emission by the 2050s and the rule on heavy-duty truck emissions would "deliver critical ...
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.
