A system includes a first separator configured to receive waste water, retain a first portion of the waste water, and separate the first portion of the waste water into a first vapor and a first solid material; and a second separator in fluid communication with the first separator, the second separator being configured to receive a second portion of the waste water from the first separator and to separate the second portion of the waste water into a second vapor and a second solid material, the second separator including a first condenser, a heating element, and a first electrocoagulation unit. Related apparatus, systems, techniques and articles are also described.

An ultrapure water (UPW) generation and verification system can include a cleaning chemical station, a cleanup column, a conductivity verification station, and a holding reservoir, in fluid communication with one another. The cleaning chemical station can be configured to selectably permit a flow of water to pass therethrough to the cleanup column or to block the flow of water and instead deliver a cleaning chemical to the cleanup column. The conductivity verification station can be configured to selectably perform at least one of the following: permit water to flow from the cleanup column to the holding reservoir; direct fluid to waste; or test the conductivity of the water for a purity level.

A water softening system includes a water feed channel through which water to be treated flows, and a crystallization unit that causes a metal ion contained in the water to be treated to precipitate. Further, the water softening system includes a separation unit that separates the water to be treated having passed through the crystallization unit into a crystal obtained through precipitation by the crystallization unit and soft water. Further, the water feed channel is configured so that at least a part thereof functions as a feed channel being a pressure application system in a substantially sealed state, and the crystallization unit and the separation unit are connected to parts corresponding to the feed channel being a pressure application system in a substantially sealed state in the water feed channel.

An ultrasonification system is provided. The ultrasonification system includes a duct having a proximal end and a distal end, and a vibrating head disposed within the duct near the proximal end thereof. A fluid enters the duct from the proximal end and flows toward the distal end. Related apparatus, systems, techniques, and articles are also described.

Disclosed is a membrane bioreactor (MBR) system. The MBR system according to one embodiment of the present invention includes a membrane filtration tub, a filtration portion including a filter member and installed in the membrane filtration tub, a filtered water storage tank, an air tank configured to store air to be supplied to the filtration portion, a flow channel portion including a first flow channel configured to connect the filtration portion to the filtered water storage tank and a second flow channel configured to connect the filtration portion to the air tank, a valve portion including a first valve located on the first flow channel and configured to open or close the first flow channel and a second valve located on the second flow channel and configured to open or close the second flow channel, and a decompression portion.

A reverse osmosis desalination system has a combined displacement pump and displacement pressure recovery motor that propagate feed water with a structurally fixed recovery rate and structurally stabilized volume flow through continuously alternating discharging and recirculation intervals. Thereby enabled is an instantaneous discharge of the entire feed water concentrate and unmixed replacement with low salinity source water that intermittingly and effectively flushes the reverse osmosis membranes. This in turn provides for high recirculation peak salinity and recovery rate that are simple and reliably controlled without impairing membrane longevity.

Commercially beneficial carbon-containing fractions can be recovered from hydrothermal liquefaction reactions in various types of processors. Feedstock slurry from waste solids is placed into a pressurized processor where it is maintained at temperature and pressure for a predetermined period. On discharge from the processor the processed discharge is separated into liquid and solid fractions. Gaseous fractions including carbon dioxide can also be removed or off-taken from the processor. New molecular structures are created in this reaction, resulting in fractions including biogas, biofuels, biosolids and biocrude. Silica, phosphates, potash and low concentration nitrogen based fertilizer, along with carbonaceous material can also be recovered.

A method and system for water body algae control are provided. The method for water body algae control may include the steps of: withdrawing water from the water body; infusing a gas containing oxygen and/or ozone into the withdrawn water by generating nanobubbles of the gas within the water; and returning the infused water into the water body. The water body algae control system may include a nanobubble generator that may be configured to receive water that is withdrawn from a water body. An oxygen concentrator and an air compressor may be configured to provide a gas containing oxygen to the nanobubble generator and/or to an ozone generator, in which the nanobubble generator is configured to disperse nanobubbles of the gas containing oxygen and/or ozone into the water, and in which the nanobubble containing water is then directed back into the water body.

Systems and methods for aeration and mixing processes are disclosed.

Water treatment and purification system as disclosed herein relates to a PLC controlled system utilizing a hydroxyl radical generation unit and system to treat polluted water. The system uses a hydroxyl-based advanced oxidation based on natural processes that keeps our atmosphere clean and breathable. This technology creates its own high concentration of hydroxyls that are put through a venturi system into the water to be purified to eliminate unwanted organic compounds such as hydrogen sulfide, pathogens, chloride resistant parasites, and harmful bacteria. The system can also reduce inorganic contaminants including iron and manganese.
