A fluid vapor distillation system. The system includes a control system for controlling a fluid vapor distillation apparatus including a blow down controller for controlling a blow down valve, a source flow controller for controlling a source flow valve, and a blow down level sensor in communication with a blow down controller and a source flow controller, the blow down level sensor sends signals related to the blow down level to the blow down controller and the source flow controller indicative of the blow down level, wherein the source flow controller actuates the source flow valve based at least on the blow down level sensor signals, and wherein the blow down controller actuates the blow down valve based at least on the blow down level sensor signals, whereby the blow down level and the source flow level are maintained using the blow down level sensor signals as input.

A system of closed circuit desalination (CCD) units powered by solar panels and/or wind turbines through a buffer battery and a DC/AC converter, operating by a change of flux as function of the power availability from the abovementioned natural energy sources, while the load of the buffer battery remains at a preselected level is provided. The programmable logic controller of the system continuously tracks the battery load; in case of drop in load (output>input) the system responds periodically by a flux decline or by a flux increase in case of load increase (output<input), such that the average battery load remains around the preselected level. Permeate production by the system proceeds as function of the NMEn configuration of the CCD unit (N, module-number; n element-number), the area of solar panels and/or the rotor sweep area of the wind turbines, and the power availability of the renewable energy source.

An apparatus for water purification includes a membrane distillation (MD) cell; an air conditioner; a photovoltaic solar collector (PVSC) cell including a transparent photovoltaic cell configured to generate electricity, an absorber plate configured to absorb solar radiation, and a flow tube configured to receive the fluid; a first heat exchanger; a second heat exchanger; and a fluid source storing a fluid configured to circulate through the apparatus, wherein the fluid circulating in the apparatus carries heat generated by a condenser of the air conditioner to the PVSC cell where the fluid interacts with the PVSC cell to increase a temperature of the fluid to become a heated fluid; and the heated fluid circulates to the hot channel where the heated fluid drives the distillation of water in the MD cell.

Catalyst systems employing inexpensive and readily-available protic co-catalysts to increase a proton reduction rate in a hydrogen evolution reaction (HER) are described herein. The protic co-catalysts function to increase the rate without being consumed in the process of water splitting to hydrogen and oxygen. They may simultaneously serve to stabilize the pH of the water and be the electrolyte to carry the current for the electrolytic splitting of water. The protic co-catalysts also decrease the overpotential energy requirement for the process of water splitting. These protic co-catalysts can be used with both heterogeneous and homogenous catalysts, as well as assist photocatalysis and other processes for the reduction of protons.

A compound multi effect distillation (MED) system of integrated backward and forward fed MED systems. Heated concentrate from the hottest effect of the backward fed MED system is delivered as feed to the hottest effect in the forward fed MED system, to generate a more concentrated brine than possible using any of the systems alone. Furthermore, coupling the systems creates additional operational advantages and increases distillation efficiency.

A Multi-Stage Wastewater Treatment and Hydroponic Farming Device comprises a compact basin, a moving bed biofilm reactor (MBBR), a modified wetland material, at least one microbial fuel cell (MFC) and a distributor. The MBBR and modified wetland material are disposed within the basin. Openings in the distributor retain hydroponic plants. In one example, wastewater enters through the MBBR which performs primary treatment of wastewater. Treated wastewater is further treated by modified wetland material and the MFC which generates electrical energy that supplies other components. Treated wastewater is pumped through the distributor and processed by hydroponic plants which extract growth inducing nutrients from the treated wastewater. Resultant water treated by the device is selectively recycled through various parts of the device or extracted from the device and used for other purposes. In one example, multiple devices are deployed in an area thereby providing self-sustaining, efficient water treatment and farming functionality.
