A method of treating aqueous, preferably concentrated, waste streams with a unique combination of steps in a way that is easily scalable and able to be used with batch or continuous flows. The method comprises at least the following steps: Adding at least one precipitating agent to the waste water to produce precipitated solids; and removing the precipitated solids from the waste water using a forward flushable membrane to remove the precipitate solids.

A water filter cartridge includes a sediment filter, a carbon filter, and a core having a tubular body with openings that allow water to flow through the core. The core defines an open central area, and the core supports the sediment filter and the carbon filter. A nanofiltration unit is arranged within the open central area of the core. The nanofiltration unit includes a tubular filter element defining a central volume, and a plurality of filaments arranged within the central volume.

Methods and for treatment of cancer and other diseases including complications from late stage viral infections by inducing hyperthermia in a patient relying on withdrawing blood from the patient and returning the withdrawn blood to the patient to establish an extracorporeal flow circuit. Blood is heated by passing through the extracorporeal circuit at a controlled rate until a target body core temperature in is achieved. Usually, the blood will be subjected to a continuously re-circulating dialysis to balance electrolytes. Additionally, the blood will be subjected to a continuously recirculating regeneration through a carbon sorbent column where toxins and contaminants are removed. The blood temperature is maintained at the target blood temperature for a treatment period, and the blood is cooled after the treatment period has been completed. The method can also be effective in treating rheumatoid arthritis, scleroderma, hepatitis, sepsis, the Epstein-Barr virus, and patients with life threatening complications from other viruses, including the COVID-19 virus. A method for removing viruses from the blood supply in an external circuit is also presented.

A reverse osmosis system for a seawater desalination system is provided. The reverse osmosis system includes: a high pressure pump configured to supply pretreated seawater at high pressure; a reverse osmosis apparatus configured to desalinate by reverse osmosis the seawater supplied from the high pressure pump; and a pressure exchanger connected to a high salinity water outlet of the reverse osmosis apparatus and configured to recover part of pressure of discharged high salinity water to the reverse osmosis apparatus, wherein the reverse osmosis apparatus includes: a vessel in which a plurality of reverse osmosis membrane units are arranged in a first stage and a second stage; an inflow and outflow portion coupled to a first end of the vessel and connected to a seawater inlet and a high salinity water outlet; a partition wall configured to partition an inner space of the inflow and outflow portion into two spaces; and a transport space portion coupled to a second end of the vessel and configured to guide the seawater moved from a plurality of reverse osmosis membrane units arranged in the first stage to move to a plurality of reverse osmosis membrane units arranged in the second stage.

Process for upgrading effluent treatment plants for pulp and paper production processes, where salts are removed from the effluent for water reuse and chemical recovery. The process comprises a first dialysis system for salt removal, a second treatment system for recovery or re-concentration, and optionally a post-treatment of the re-concentrate preventing liquid discharges to the environment. In the first system, a reversible electrodialysis or reversible pulsed step is carried out, separating the salts from the effluent, which are sent to the second treatment system to concentrate the salts (re-concentrate) or transform them into useful chemicals for the same process (recovery). Chemical recovery is achieved by electrodialysis with bipolar membranes or metathesis, to reduce the re-concentrate stream, which cannot be reused in the same plant. Lastly, this stream may be treated by spray drying, crystallization or evaporation.

A portable water conditioning system is provided that includes a water conditioner, a first sensor, a second sensor, and a controller. The water conditioner has a plurality of conditioning stages that condition water. The plurality of conditioning stages include, in a direction of flow of the water through the water conditioner, a reverse osmosis stage and a deionizing stage. The first sensor detects a first condition of the water before the reverse osmosis stage. The second sensor detects a second condition of the water after the reverse osmosis stage. The controller is in communication with the first and second sensors and determines a health status of the reverse osmosis stage based the first and second conditions. The first and second conditions each include a level of total dissolved solids of the water.

This application relates generally to the processing of egg protein isolates for use in various food, sports nutrition and nutraceutical applications, methods of making egg protein isolates, and apparatus for making egg protein isolates. More particularly, the application relates to a method of deflavoring egg products and concentrating the protein content to. The method can include providing liquid egg; deashing the liquid egg; concentrating the liquid egg; and desugaring the liquid egg, wherein deashing is accomplished at a pressure of less than 100 psi; and optionally the volume of water used is 0.5 to 7 diafiltration volumes.

For powering a vehicle, a high energy density fuel is preferred. However, for example when the high energy fuel is highly concentrated hydrogen peroxide, this fuel may be dangerous to handle; especially when the person handling the fuel is a normal consumer filling a fuel reservoir of his vehicle at a gas station. The present invention therefore provides a vehicle arranged to receive a diluted—and thus safer—fuel, and to density this fuel to a concentrated fuel in low quantities on board for direct use. To this end a fuel densifier is provided in the vehicle arranged for receiving liquid diluted fuel and arranged to provide a concentrated fuel based on the diluted fuel, the concentrated fuel having a higher energy density than the diluted fuel. A power conversion module of the vehicle is arranged to convert the concentrated fuel to kinetic energy for powering the vehicle.
