A water sanitizing system is disclosed and includes an inner chamber and an outer chamber disposed at least partially around the inner chamber. A lens concentrates solar energy applied to a liquid within the inner chamber. A vacuum source in communication separately with the inner chamber and the outer chamber. The vacuum source controls a pressure within the inner chamber separately from the outer chamber for controlling conversion of liquid within the inner chamber to a gas. The outer chamber, also under vacuum, is an insulative layer to prevent heat loss.

An apparatus for removing large particles from a vessel The apparatus includes a vacuum storage container and a suction hose extending from the vacuum storage container. The vacuum storage container includes a material receiving section, a grinding pump and a disposal line. The material receiving section receives the large particles from the suction hose. The grinding pump is positioned in the material receiving section for pulverizing the large particles received in the material receiving section. The disposal line extends from the grinding pump through the vacuum storage container to remove the pulverized material from the grinding pump and the vacuum storage container.

A small processor produces potable water from contaminated water. Its components mount in a hermetically sealed housing, which include a boiler-condenser assembly and a compressor unit. Contaminated water is injected onto one or more aluminum shells' inside surface of the boiler-condenser assembly. Shell rotation enhances boiling heat transfer by causing the water to form thin films on the shells' inside surface. Shell rotation also enhances condensing heat transfer by assisting in removing the purified condensate from the shells' outer surface. The change of phase heat of condensation energy from vapor to liquid transfers through the shells to the boilers to cause boiling. Vapor boiled inside the boiler chambers flows toward the compressor, which raises the vapor's pressure and temperature to drive the process. Shell rotation causes centrifugal force that holds and directs concentrated un-boiled remaining water on the shells' inside walls towards the output pumps. Wipers mounted adjacent each shell's boiler surface smooth contaminated water. Wipers adjacent the condenser surfaces help remove condensate from that surface to present a clean condenser for improved condensation.

A system for treating excrement of livestock includes: reduced-pressure fermentation drying equipment configured to store excrement of livestock in an airtight container, heat and stir the excrement of livestock under reduced pressure so that a temperature of the excrement of livestock is within a predetermined temperature range, decompose organic components of organic matter using microorganisms, and obtain volume-reduced dried product; and heat source equipment that is provided on a downstream side of the reduced-pressure fermentation drying equipment and generates a heat source by combusting the obtained volume-reduced dried product.

A system and process for decontaminating a bio-contaminated wastewater fluid as from a slaughterhouse or similar facility. The system and process recovers purified vapor/steam through a decontamination unit having a plurality of alternating rotating trays and fixed baffles in a processing vessel producing separate purified and contaminant streams. One or more filter/strainer units are disposed in parallel before the decontamination unit, and may be used alternately while the other is cleaned. A rotating shaft connected to the rotating trays may also connected to an electrical generator to provide electricity for circuits and controls in the system.

Vacuumed gap membrane distillation (VAGMED) modules, and multi-stage VAGMED systems and processes using the modules are provided. In an embodiment, the membrane distillation modules can comprise: a) a condenser including a condensation surface; b) a first passageway having an inlet for receiving a first feed stream and an outlet through which the first stream can pass out of the first passageway, the first passageway configured to bring the first feed stream into thermal communication with the condensation surface; c) an evaporator including a permeable evaporation surface allowing condensable gas to pass there through; d) a second passageway having an inlet for receiving a second feed stream and an outlet through which the second feed stream can pass out of the second passageway, the second passageway configured to bring the second feed stream into communication with the permeable evaporation surface; and e) an enclosure providing a vacuum compartment within which the condenser, the evaporator and the first and second passageways of the module are contained.

A biological reactor system treats concentrated contaminated water with a combination of upflow and downflow bioreactors that are downstream from a reverse osmosis or other concentrator. The system may have a fail safe configuration where flush water may be introduced to the reactors in the event of a power failure or when taking the reactors offline. Many reverse osmosis systems introduce antiscalant treatments upstream so that the reverse osmosis filters do not scale. However, such treatments result in superconcentrated conditions of the antiscalants in the contaminated water processed by the bioreactors. A flushing system may deconcentrate the bioreactors to prevent the antiscalants from precipitating and fouling the bioreactors.

A method and apparatus are disclosed for treating process water which is loaded with gaseous compounds and/or possibly with solids and comes from a wet-cleaning installation for cleaning process gas, e.g., from a melt-reduction subassembly or from a direct-reduction subassembly. Process water is introduced in a tank in a first process stage and degassed on the basis of reduced solubility of the dissolved compounds. The tank has, on its upper side, a gas-collecting chamber, in which the separated-off gases are collected and from which these are discharged. Likewise, the treated process water is discharged from the tank via a drainage means.

A three-dimensional electrode-ozone oxidation-electrocatalytic membrane coupled wastewater treatment device, including a circulating fluidized bed reactor. The circulating fluidized bed reactor includes a funnel-shaped internal, a truncated cone, a fiber ball filter, a gas-liquid distribution plate, an inner cylinder, an intermediate cylinder and an outer cylinder. The inner cylinder, the intermediate cylinder and the outer cylinder are coaxial. The inner cylinder is an electrocatalytic membrane assembly; the intermediate cylinder is a gas diffusion electrode; and the outer cylinder is a stainless-steel mesh. A particle electrode is filled between the intermediate cylinder and the outer cylinder, and between the intermediate cylinder and the inner cylinder. The intermediate cylinder is connected to a negative electrode. The inner cylinder and the outer cylinder are connected to a positive electrode. A wastewater treatment method using the device is also provided herein.

A bubble removing system and a bubble removing method are provided. The bubble removing system comprises a main bubble removing apparatus which comprises a first enclosed container, a first fluid lead-in pipe, a first fluid lead-out pipe, and a bubble collecting member. The cross section of the inner cavity of the first enclosed container is circular, and the first enclosed container is used for accommodating a fluid substance. The first fluid lead-in pipe passes through a sidewall of the first enclosed container, is tangent to the inner cavity wall of the first enclosed container, and is disposed at the upper part of the first enclosed container. The first fluid lead-out pipe passes through the sidewall of the first enclosed container and is disposed at the lower part of the first enclosed container.
