A method for the manufacture of a high alumina hydraulic binder comprising hydrating a source of aluminium ions with a source of calcium ions in the presence of water to form mineral hydrates and subsequently heating said mineral hydrates to form said high alumina hydraulic binder.

This invention relates to a treatment method and apparatus directed to improving water quality, increasing net energy production, and reducing greenhouse gas emissions without employing bioreactor processing for waters containing suspended organic solids, PPCPs, PFAS, negative colloids, heavy metals, phosphates, nitrates, carbonates, silicates, chlorides and sodium ions. It employs SO.sub.2, sulfites and bisulfites to self-agglomerate suspended organic solids with sorbed PFAS and PPCPs, and acid leach heavy metals into solution. Subsequent liming filtration separates of metal hydroxides and insoluble calcium salts while chemically conditioning the separated organic solids for gasification or burning. The second filtrate is then exposed to ultra violet light for pathogen disinfection, and exciting sulfites to remove nitrates, and degrade PFAS and PPCPs to form a disinfected metal free salt balanced reclaimed wastewater with reduced PFAS, PPCPs, pathogens and negligible nitrogen and phosphorous.

A system for urban organic solid waste pyrolysis-gasification coupled with drying includes a sludge feeding and storage device, a pre-drying device, a cyclone separator, a specific cloth bag for sludge and a flue gas waste heat recovery device sequentially connected. The cyclone separator and a sludge outlet of the specific cloth bag for sludge are connected with a cyclone fluidized bed gasification furnace. The cyclone fluidized bed gasification furnace is connected with a high-temperature separator. The high-temperature separator is connected with a secondary combustion chamber. High-temperature flue gas generated by the secondary combustion chamber serves as a heat source of the pre-drying device. Ash generated by the high-temperature separator and secondary combustion chamber is sent to an ash bin after being cooled by a cold slag conveyor. Through system integration and optimization, the disclosure adopts a two-stage process of pre-drying and pyrolysis-gasification, thus having high process controllability and operability.
