To produce fertilizer, a system and method concentrates manure slurry in a mechanical vapor recompression evaporator (MVR) having a heat exchanger. The MVR receives the manure slurry within a first side to evaporate ammonia laden-water vapor from the slurry, leaving a nutrient concentrate. A compressor raises the evaporated ammonia-laden water vapor to a higher energy state. Within a second side of the heat exchanger, the compressed water vapor conveys heat to the slurry. Ammonia-laden water condenses in the second side at a process temperature to be conveyed to an ammonia stripping tower where the ammonia-laden water is dispersed into ammonia-laden water droplets. In the tower, a flow of air is directed across a surface of the ammonia-laden water droplets, the process temperature having been selected to promote the escape of ammonia gas from the ammonia-laden water droplets, the flow of air provided to entrain ammonia gas in the flow.

The present invention discloses a method and a system of treating biomass wastes by biochemistry-thermochemistry multi-point interconnection. The present invention applies solid, gas and liquid products of the thermochemical treatment subsystem to the biochemical treatment subsystem and applies heat produced by the biochemical treatment subsystem to the thermochemical treatment subsystem, forming multi-point and two-way interconnection between the biochemical treatment subsystem and the thermochemical treatment subsystem, thereby increasing the yield and stability of energy gas of the biochemical treatment subsystem and reducing pollution and energy consumption of the thermochemical treatment subsystem respectively. The present invention is suitable for treating biomass wastes with high and low water contents at the same time, producing soil amendment, liquid fuel and biogas, having properties of low secondary pollution and significant reduction of greenhouse gas emission and so on. The bio-stability, humus content and nitrogen content of the solid product are as high as soil amendment, making it easy to store and transport.

An intelligently controllable food waste disposal system and method are provided. A food waste disposal machine has operational components adapted to assist in the disposal of food waste. A programmable logic controller (PLC) is in data communication with the operational components and configured to control operation of the operational components. A minicomputer is connected to the PLC and adapted to write PLC instructions to the PLC. A network connection is in data communication with both the minicomputer and an analytics cloud. The minicomputer receives data from the analytics cloud and transfers PLC instructions corresponding to the received data to the PLC to thereby alter the operational control of the operational components of the food waste disposal machine via the PLC. The PLC controls the operational components via a default operational program written into the PLC when the PLC detects that the minicomputer is not in communication with the PLC.

A water purification system comprises a bioreaction subsystem receiving contaminated input effluent and having a gas-lift anaerobic membrane bioreactor removing urea and organic matter to create a first effluent. A light-treatment subsystem receives the first effluent and exposes the first effluent to UV light to create a second effluent free from microorganisms. A reactor subsystem fluidically connects an ammonia-reducing reactor to the UV output and receives UV-treated second effluent and has a struvite regenerator connected to the ammonia-reducing reactor output, separating ammonia from the second effluent in the ammonia-reducing reactor, and outputting the ammonia. A separation subsystem fluidically connects to the reactor output and receives the second effluent substantially free from ammonia and has a continuous electro-deionization device separating brine/salts from the second effluent to produce potable water. A closed-loop includes an ammonia-converting subsystem and a sequential fertilizer producer.
