A Zero Liquid Discharge (ZLD) process diagram that highlights how wastewater from an industrial process is converted to solids and treated water for reuse via a ZLD plant. Concept of ZLD Zero Liquid Discharge (ZLD) is a classification of water treatment processes intended to reduce wastewater efficiently and produce clean water that is suitable ...
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 ...
Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
For example, once a pipeline containing the brine reaches the sea floor, it can split into many branches, each releasing brine gradually through small holes along its length. Mixing can be combined with power plant or wastewater plant dilution. Furthermore, zero liquid discharge systems can be adopted to treat brine before disposal. [120] [123]
The work done in a process is the area beneath the process path on a P-V diagram. Figure 2 If the process is isobaric, then the work done on the piston is easily calculated. For example, if the gas expands slowly against the piston, the work done by the gas to raise the piston is the force F times the distance d.
This enables very high levels of valve acceleration and lift and also very small valve-to-valve and valve-to-piston clearances to be used in combination with very high engine speeds. For example, prior to the FIA restrictions, Formula 1 engines ran at speeds of over 20,000 RPM and power outputs of over 330bhp/litre normally aspirated using a ...
The LiquidPiston design reverses the shapes: a figure-eight-shaped rotor moves within a triangular housing. The required seals (both face and apex) are mounted on the stationary housing, which makes lubrication much easier. Common to both concepts is the use of ports to supply air and remove exhaust gas, thereby eliminating the need for valves.
