The invention relates to a new biological fluidized bed process with high concentration powder carriers used for the treatment of municipal wastewater, which is a fluidized bed system based on the principle of sewage biochemical treatment, by adding a compound powder carrier to the biochemical tank, and forming a high concentration mixture after mixing and microbial attachment; the sludge mixture after the reaction is concentrated and separated, and then enters the compound powder carrier cyclone separation and recovery system, which can separate most of the compound powder carrier from the discharged excess sludge, and then return to the biochemical tank for recycling. The highly integrated municipal wastewater treatment process proposed in the invention has high treatment efficiency, small occupation area, low operation energy consumption, and can realize the doubling of sewage treatment capacity and the improvement of effluent water quality without adding additional occupancy.

The present invention provides stretchable laminates with a flat appearance on the visible surface. The laminates comprise a textile layer, a functional layer, and a plurality of elastic fibers. The plurality of elastic fibers are in a substantially parallel arrangement and the internal distance between adjacent fibers does not exceed the maximum fiber spacing, which depends on laminate thickness in a stretched state. Also provided are garments and footwear comprising the stretchable laminates and methods of producing the stretchable laminates.

A sewage treatment device includes a fluidized bed body, a reflux device and a chemical feeding device. The fluidized bed body is sequentially provided with a sedimentation zone, a transition zone and a fluidization zone from top to bottom. The reflux device is connected to the fluidized bed body through a reflux pipe. The reflux pipe extends into the fluidized bed body from the sedimentation zone, and the granularity of a crystal product can be controlled by changing the height of a reflux inlet at the bottom end of the reflux pipe in the fluidized bed body. By controlling the position of the reflux inlet of the reflux pipe in the fluidized bed body, combining product granularity requirements, and adjusting an insertion depth of the reflux pipe, the granularity of a final product can be flexibly regulated and controlled, and meanwhile, a product recovery rate is improved.

The present invention refers to an industrial process and system that is efficient and advantageous for inactivation of liquid wastes contaminated by mutagenic, genotoxic and/or teratogenic substances arising from high potency APIs production using inactivation chemical agents and excluding ozone, heat or UV light source.

A high salinity water purification system and process, including a forward osmosis system and a reverse osmosis or nanofiltration system. A concentrated brine of a zinc or iron complex combined with a salt or acid draws pure water across the FO membrane from the influent water. The diluted brine is pumped through a vessel holding an anionic adsorption media to remove the zinc or iron complex and the resultant brine is passed through the RO or nanofiltration system to obtain purified water and a concentrated brine stream. The adsorption media is regenerated by a rinse cycle using fresh water or water from the RO system, removing the zinc or iron complex adhered to the media. The resultant brine is stored and mixed with the output of the RO system. Charged membrane can be used as a standalone membrane in FO process or in combination with resin or resin embedded membrane.

The sub-ambient solar desalination system includes a solar pond and a pressure reducing structure. The solar pond is adapted for receiving saltwater and heating the saltwater through direct exposure to solar radiation at atmospheric pressure. The pressure reducing structure is in fluid communication with the solar pond for receiving heated saltwater therefrom. The pressure reducing structure is configured such that pressure of the heated saltwater within a central portion of the pressure reducing structure is at sufficiently reduced sub-ambient pressure to undergo a phase change to produce pure water vapor and a concentrated brine solution. The pressure reducing structure has a vapor outlet for releasing the pure water vapor, which is collected in a fresh water tank and condensed into pure liquid water. The solar pond is in fluid communication with an outlet portion of the pressure reducing structure for recycling the concentrated brine solution back to the solar pond.

A system for treating and/or recycling gray water includes a first receiving tank for gray water, a second receiving tank for treated water and a fluidic treatment circuit between the first and second receiving tanks. The first receiving tank includes an element for oxygenating the water in the first receiving tank and a system adapted to deliver enzymes into the first receiving tank. The fluidic treatment circuit includes a filtration unit, a microfiltration unit including at least one microfilter, a disinfection unit and a membrane ultrafiltration unit.

The single-hand-operable micro water purifier of the present application relates to a micro water filter, especially a micro water purifier which can filter water by means of pressuring. It consists of a micro filter device and a raw water pressurizing device. The micro filter device consists of a filter cylinder body, a filter water inlet, and a filter water outlet and a filter material assembly located in the filter cylinder body. The raw water pressurizing device consists of a pressurizing device water inlet, a pressurizing device main body, and a pressurizing device water outlet. The present application can promote the raw water to enter the filter device for performing the filtration to obtain the clean water, by using a single hand to operate, which not only brings convenience to the user, but also saves labor and improves the use efficiency.

A universal water purification system and method that can desalinate salt water or just filter fresh water. Preferably, the system is portable and relatively lightweight and provides for emergency or recreational safe power and water accessibility. The components of the system can be installed on an aluminum frame and preferably include one or more of a waterproof front control panel, four pre-filters, a reverse osmosis membrane or graphene filter, or electrical process of separating chloride ions from water, ultraviolet (UV) LED lamp, ultrasonic frequency generator, chlorinator or disinfecting gas infusion, a high pressure reverse osmosis (RO) pump, or other desalination process and a low pressure water supplying pump, an electro valve preferably with a manual override in case of power loss and can be activated based on the content of total dissolved solids of incoming water. The system may be removably inserted into a suitcase that can be carried by an individual, or housed in a frame with wheels.
