SYSTEMS AND METHODS FOR DESTROYING PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS) USING AN ELECTROCHEMICAL (EC) REACTOR
A treatment system including an influent pump to pump influent fluid stream containing PFAS into the system. The system may include a flow recirculation system including a fluid circuit through which a recirculating fluid stream flows, an electrochemical (EC) reactor comprising at least one pair of electrodes. When the EC reactor is in a first operational mode, a current generated between the anode electrode and the cathode electrode destroys at least some of the PFAS. The system may include a foam management system to reduce an amount of foam in a container of the EC reactor. The system may include a chemical management system to inject a chemical into the recirculating fluid stream. The system may include a temperature control system to regulate a temperature of the recirculating fluid stream. The system may include a recirculation pump to pump the recirculating fluid stream through the flow recirculation system.
Digestion of organic sludge
The invention is in the field of organic sludge digestion from various sources, such as manure, sludge from a wastewater treatment plant, and an organic fraction of dredging sludge. The present method provides advanced control for serially treating aqueous organic sludge by anaerobic digestion. It further relates to dewatering of the obtained biomass.
Compact containerized system and method for spray evaporation of water
An evaporation system for spray evaporating undesired water comprising: a first pump, a container comprising a sump, a second pump, a spray manifold comprising a spray nozzle, a packing system, a third pump, and an air system comprising an air blower and an air preheater is disclosed. A first portion of a ceiling of the container is constituted by a demister element. A second portion of the ceiling is adjacent to an upper edge of a wall of the container. The first pump is connected to an inlet of the container. A draw line is disposed in the sump, and is connected to an inlet of the second pump. An outlet of the second pump is connected to an inlet of the spray manifold. The third pump is connected to the sump and a discharge outlet. The air system is disposed through the wall of the container, and discharges air flow counter to and/or crossways to the water droplets from the spray nozzle.
Microbial assisted phosphorous recovery under anaerobic condition
A system and method for treatment of wastewater, in which the system includes a blackwater reactor configured to receive a stream of blackwater influent, to contain the blackwater therein during treatment of the blackwater, to facilitate recovery of methane and nutrient precipitates therefrom, and to output partially treated blackwater, and a greywater reactor configured to receive a stream of greywater influent and the partially treated blackwater output from the blackwater reactor, to contain the greywater and the partially treated blackwater therein during greywater treatment, and to output greywater treatment discharge. The process includes inputting a stream of blackwater into the blackwater reactor; treating the blackwater in the blackwater reactor with an anaerobic digestion process; controlling a pH level of the blackwater within the blackwater reactor; recovering nutrient precipitates from the blackwater reactor, optionally independent of chemical additives; and recovering methane from the blackwater reactor.
MEMBRANE-BASED SEPARATION OF MICELLE-ASSOCIATED PFAS MOLECULES
Certain aspects of the present disclosure are related to systems and methods related to the removal of PFAS molecules. In one aspect, systems comprising a membrane separator and a foam fractionation separator are generally described. In some embodiments, the membrane separator and the foam fractionation separator are fluidically connected such that some or all of a feed comprising PFAS molecules, a surfactant, and a liquid and/or a foam fractionation separator input comprising PFAS molecules and a liquid can be processed by the membrane separator and/or the foam fractionation separator. In some embodiments, at least a portion of the PFAS molecules are removed from the feed and/or the foam fractionation separator input. In some embodiments, the surfactant is present such that some or all of the PFAS molecules are associated with micelles, which may facilitate the removal of the PFAS molecules from the feed and/or the foam fractionation separator input. In some embodiments, the membrane separator rejects PFAS molecules (e.g., associated with micelles) to a greater extent than certain dissolved ions.
Homogenous emulsion from a grain material fermentation
The present disclosure relates methods and systems for refining grain oil compositions using water, and related compositions produced therefrom. The present disclosure also relates to methods of using said compositions. The present disclosure also relates to methods of using grain oil derived from a fermentation product in an anti-foam composition. The present disclosure further relates to stabilized emulsion products and methods for forming thereof.
Process for anaerobic digestion of carbonaceous material
A process of treatment of carbonaceous material, such as wastewater sludge or organic waste, includes performing a thermal treatment of the carbonaceous material, thereby providing thermally treated carbonaceous material, cooling the thermally treated carbonaceous material, thereby providing cooled carbonaceous material, the cooling being performed using a vacuum cooling procedure, and performing a post-treatment of the cooled carbonaceous material, and at least one carbonaceous material degassing.
