The present disclosure is concerned with sea water demineralization. More specifically, to systems, methods, and apparatus for water demineralization and purification, including the removal of dissolved solids and contaminants from sea water, industrial water with mineral content, and brackish water.

The present invention comprises a closed loop system for the removal of contaminants from wastewater while evaporating the water by utilizing a continuously running evaporator in communication with a separation tank wherein water is returned to the evaporator and solids are left in the separation tank for disposal.

A wastewater concentrator a liquid evaporator assembly, a gas-liquid separator, an exhaust assembly, and a flowback water concentrating system. The flowback water concentrating system includes a settling tank fluidly connected to the gas-liquid separator and a supernatant liquid concentration sensor for measuring a concentration of dissolved solids in the supernatant liquid in the settling tank.

An evaporation and condensing system having a structure including an evaporator section and a condenser section. A first nozzle system is disposed in the evaporator section. The first nozzle system is in communication with a first feed pipe disposed at least partially in the structure, the first feed pipe is adapted to be in communication with a first substance. A second nozzle system is disposed in the condenser section. The second nozzle system is in communication with a second feed pipe disposed at least partially in the structure. The second feed pipe is adapted to be in communication with a second substance. A first porous knockout panel is disposed proximate the evaporator section. A second porous knockout panel is disposed proximate the condenser section. A first substance drain is disposed in the evaporator section. A second substance drain is disposed in the condenser section.

A wastewater treatment system includes a circulating fluidized bed evaporator defining a longitudinal axis vertical with respect to gravity. The evaporator has a wastewater inlet to provide wastewater to the circulating fluidized bed evaporator. A heat inlet is axially below the wastewater inlet to provide heat to the circulating fluidized bed evaporator for evaporating the wastewater. An outlet is axially above the wastewater inlet and the heat inlet.

A process for treating effluent streams in a renewable transportation fuel production process is described. One or more of the sour water stream and an acid gas stream are treated directly in thermal oxidation section. The process allows the elimination or size reduction of a sour water stripper unit, waste water treatment plant, and sulfur recovery unit.
