THERMOMECHANOCHEMICAL WASTE TREATMENT

Apparatus and systems are provided for processing PFAS-contaminated waste via thermomechanochemical (TMC) processing. In one example, a system may include a TMC processing chamber including a milling system and coupled to a heating system, the heating system configured to co-operate with the milling system to process the waste material. A plurality of containers including the waste material in one or more of a liquid-solid state, a semi-wet or slurry solid state, and a dry solid state are coupled to the TMC chamber.

Method of recovering iron and/or phosphorus from sludge of waste water treatment plants
20180208481 · 2018-07-26 ·

Method of recovering iron and/or phosphorus from sludge of waste water treatment plants, said sludge being obtained after precipitation by iron salts, wherein said method comprises separating sludge from waste water and submitting said sludge to a lactic fermentation to release a liquid phase where iron and phosphorus are dissolved. Lactic fermentation is performed with addition of a co-substrate rich in carbon, preferably rich in carbohydrate, in one single step of biological acidification or a sequencing biological acidification in two steps by first releasing phosphorus from the PAO contained in the sludge. Iron can then be recovered by means of a cationic exchange resin. Phosphorus can be recovered as struvite or calcium phosphate from the remaining solution substantially free from iron ions, after a precipitation step in presence of a magnesium or calcium source and a pH above 7.

Method of reducing and controlling hazardous substance in process of high-value biological conversion of urban organic waste

The present invention provides a method of reducing and controlling a hazardous substance in a process of high-value biological conversion of an urban organic waste. The method includes: 1) mixing a sludge, a first urban organic waste and an organic acid with water for acclimation to obtain an acclimatized sludge; 2) stage 1 of biological conversion: mixing the acclimatized sludge with a second urban organic waste to perform anaerobic culture; 3) stage 2 of biological conversion: adding nitrate and bacteria to continue anaerobic culture so as to obtain an organic acid. In the present invention, sludge microbes are acclimatized and then added to high-value chemicals such as acetic acid, propanoic acid and lactic acid prepared in biological conversion of the urban organic waste and then added with bacteria. Thus, by controlling pH value, microbe addition amount and nitrate concentration, the unfavorable effect of the antibiotics and heavy metal ions.

Process for treatment of sewage sludge
10010827 · 2018-07-03 ·

A method for pathogen destruction in dilute sewage sludge or other dilute streams containing pathogens, including Helminth ova, while minimizing vapor generation and atmospheric emissions. In addition to conventional waste treatment steps, including grit removal, clarification, and concentration of waste material, vaporized waste treatment compounds are recycled to treat divert untreated waste in a scrubber. In the scrubber, waste material is treated while also acting as a reactive agent to scrub potentially hazardous or noxious gas, particularly gaseous MITC, from the treatment system. Recycling of vaporized treatment compounds provides a reduction of potentially toxic emissions and increased efficiency during treatment.

SYSTEMS FOR EMPTYING PIT LATRINES AND SEPTIC TANKS

An example system includes an auger assembly that is attachable to a vacuum system, in which the auger assembly includes a hose, an auger, and an auger motor. The hose includes an inlet at a distal end and an outlet at a proximal end. The auger includes a shaftless helical blade having a portion that is radially enveloped by the hose. The vacuum system is adapted to suck material from the septic tank or pit latrine via the hose. The auger motor is adapted to rotate the auger about a helical axis in a first direction, in which the rotation about the helical axis in the first direction causes the shaftless helical blade of the auger to translate along the helical axis from the outlet of the hose towards the inlet of the hose.
