The present invention provides an industrial wastewater recovery apparatus (100) aiming at Zero Liquid Discharge (ZLD). The apparatus (100) provides two stages in pre-heating the spiral coil pipe (103) containing wastewater and also conserves the heat by using the two heat exchangers (104, 105). The apparatus (100) agitates the surface wastewater to increase the rate of evaporation for faster heating. The apparatus (100) provides two stages in condensation of distilled water and also provides real-time monitoring of the water quality. The apparatus (100) provides automatic cleaning in the various parts during the operations. Further, a plurality of IoT sensor (201) monitor the real time parameters of the industrial wastewater recovery apparatus (100) and data is available to the user on the electronic display device (204).

A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid. The fluid vapor distillation apparatus also includes a control system.

A system of fluid sterilization of fluid of vessel is provided, such as sterilization of ballast water for a water vessel. The system incorporates a heating section to heat pressurized fluid above prescribed thresholds for temperature, pressure, and duration (e.g., dwell time) to achieve desired levels of sterilization, including a heat exchanger to both (a) preheat fluid prior to entering the heating section and (b) cool outflow of the heating apparatus, in which fluid travels through the apparatus by operating valves forward and aft of the heating section in a controlled sequence to facilitate flow through the system while maintaining prescribed pressure and temperature profiles. The system operates within prescribed ranges of pressure and temperature to achieve the desired level of sterilization without need of maintaining a fixed temperature or a fixed pressure within any portion of the system, including the heating section.
