Embodiments of the invention are directed toward a novel pressurized vapor cycle for distilling liquids. In an embodiment of the invention, a liquid purification system is revealed, including the elements of an input for receiving untreated liquid, a vaporizer coupled to the input for transforming the liquid to vapor, a head chamber for collecting the vapor, a vapor pump with an internal drive shaft and an eccentric rotor with a rotatable housing for compressing vapor, a condenser in communication with the vapor pump for transforming the compressed vapor into a distilled product, and an electric motor with motor rotor and magnets hermetically sealed within the fluid pressure boundary of the distillation system.

Methods and systems for chemical management. In one embodiment, a blender is coupled to a processing system and configured to supply an appropriate solution or solutions to the system. Solutions provided by the blender are then reclaimed from the system and subsequently reintroduced for reuse. The blender may be operated to control the concentrations of various constituents in the solution prior to the solution being reintroduced to the system for reuse. Some chemicals introduced to the system may be temperature controlled. A back end vacuum pump subsystem separates gases from liquids as part of a waste management system.

Belonging to the technical field of soil and underground water pollution control, the invention discloses a DNAPL (dense non-aqueous phase liquid) contaminated underground water in-situ remediation method. A DNAPL contaminated underground water in-situ remediation system comprises a drilling well, a filtering device, a single-pump extraction device and a water injection device. The filtering device comprises a concrete layer, a bentonite layer and a sand-filling layer that are arranged in the drilling well from top to bottom in order. The single-pump extraction device comprises a liquid ring pump, an extraction pipe, a grid type sieve pipe and a well pipe. The water injection device comprises a water injection pipe, a vent hole and a water injection pump. One end of the water injection pipe is inserted into the well pipe, and the other end is connected to the water injection pump on the ground and is fixed to the upper end face of the well pipe. The vent hole is arranged at the upper end face of the well pipe. The DNAPL contaminated underground water in-situ remediation method provided by the invention solves the problems of limited extraction depth, difficult determination of extraction location, incomplete extraction and the like in the prior art, and has the advantages of wide application, high extraction efficiency and the like.
