Modular system of drying humid material, comprising a drier housing having a material inlet and outlet, a drying gas inlet and outlet, a particle separator downstream of drier housing. Drier housing comprises drying chambers. The system further comprises an air fan, and a heater. A gas duct connecting drying gas inlet and drying gas outlet defines a closed loop. A condenser is arranged in gas duct. Drying chambers comprises a rotary impeller means, and drying gas inlets. A dried-hot product cooler comprising a housing having a dried-hot product inlet, a cooled dried product outlet, a cool air supply means, and a fan arranged to draw cooled air through dried hot product in cooler.

A waste reduction system that utilizes organic solids suspended in a waste stream to produce carboxylic acids, which can then be employed as an input to a microbial fuel cell or other biological processes to further enhance biogas production, is provided. The organic waste stream influent undergoes a multistage fermentation process in which fermentative microorganism metabolize the organic waste materials and produce one or more carboxylic acids, especially short chain fatty acids. The carboxylic acids serve as a food source for bacteria within an anode compartment of an MFC that generates useable electricity therefrom.

An oil and sludge collecting tank is disclosed, which can be placed on-site at a food factory or the like, that discharges oil-containing wastewater, and which can collect oil and sludge more efficiently from an upper layer of an oil/water separation tank that pools the oil-containing wastewater. The oil and sludge collecting tank temporarily stores an upper layer of an oil/water separation tank, and collects oil and sludge. The oil and sludge collecting tank comprises: an upper tank TA into which the upper layer of the oil/water separation tank flows through an inflow pipe; at least one or more lower tank TB that has a smaller volume than the upper tank TA, and that is continuously provided from the bottom surface of the upper tank TA; and a lower tank heating section H2 that heats the lower tank TB.

A process for concentrating a maple sap or sweet vegetal water solution is provided. The process comprises collecting the solution in a tank at temperature T1, wherein T1 is between 4 C. and 10 C.; concentrating the solution by means of a reverse osmosis concentrator to produce a high Brix solution of about 15 to about 40 Brix; heating the high Brix solution of about 15 to about 40 Brix to temperature T2, wherein T2 is between 40 C. and 85 C.; and evaporating the high Brix solution by means of a vacuum evaporator at temperature T3 to produce the concentrated product of about 60 to about 70 Brix, wherein T3 is between 55 C. and 80 C. A system for concentrating a maple sap or sweet vegetal water solution is provided, as well as a concentrated product produced by the process of the present invention.

The present invention relates to a hygienization generator system and method for producing customized disinfection solutions by combining aqueous ozone and alkaline water. The system includes an aqueous ozone generator with an ion exchange material and electrolysis unit, an alkaline water generator capable of producing water with adjustable pH levels, and a mixer to form a homogeneous solution. A control system dynamically adjusts ozone concentration and PH levels based on user inputs or preconfigured settings, with real-time feedback provided by integrated sensors. The system features a user interface for parameter selection, remote monitoring capabilities, and optional microfoaming technology to enhance solution efficacy. Applications include surface sanitization, produce washing, dental water line disinfection, and biofilm removal in industrial piping. The portable configuration supports on-site use with modular dispensing options. This invention overcomes prior shortcomings, offering precise, eco-friendly, and versatile disinfection solutions.
