A treatment system is provided and comprises a precipitation unit and a recovery unit. The precipitation unit is configured to treat a solution using one or more miscible organic solvents to produce a mixture of precipitate solids and a liquid. The recovery unit is in fluid communication with the precipitation unit and configured to facilitate separating the liquid at least into an organic phase liquid and an aqueous phase liquid comprising a portion of the one or more miscible organic solvents. The treatment system further comprises a purification unit comprising one or more membrane devices in fluid communication with the recovery unit and configured to separate at least a portion of the one or more miscible organic solvents in the aqueous phase liquid from the aqueous phase liquid. A treatment system and a treatment process are also presented.

A water purification device, with a first pressure cylinder, a second pressure cylinder, a first connecting piece and a second cylinder block arranged successively from bottom to top, and further having a first cylinder block arranged inside the second cylinder block. The first pressure cylinder and the second pressure cylinder both are open at one end and formed with a first through-hole at the other end. The first cylinder block and the second cylinder block both are open at two ends and arranged in a hollow shape. A water inlet, which is communicated with a flow passage formed between the first cylinder block and the second cylinder block, is formed on the second cylinder block, and a water outlet pipe communicated with the first cylinder block is inserted into an outer wall of the first pressure cylinder.

A system for generating electricity, heat, and desalinated water having a gas turbine system connected to a first electric generator, a waste heat recovery boiler (WHRB) system, a combined heat and power (CHP) generation system connected to a second electric generator, one or more solar powered energy systems, and a desalination system. The desalination system is connected to the CHP generation system and the WHRB system. The gas turbine system generates electricity and heat, the WHRB system is connected to and uses the exhaust of the gas turbine system to provide heat and steam power to the CHP generation system. The CHP generation system produces and provides electricity and heat to the desalination system, which produces product water, and at least one solar powered energy system provides thermal energy to one or more of the gas turbine system, the WHRB system, the CHP generation system, and the desalination system.

A system can include a filter assembly with a filter and a substance in the filter assembly, and at least one optical computing device having an integrated computational element which receives electromagnetic radiation from the substance. A method can include receiving electromagnetic radiation from a substance in a filter assembly, the electromagnetic radiation from the substance being received by at least one optical computing device having an integrated computational element, and the receiving being performed while a filter is positioned in the filter assembly.
