Sintered Wave Multi-Media Polarity Conversion Treatment Apparatus and Process is disclosed, which uses a non-destructive physiochemical PFAS vapor emissions treatment system to provide vacuum and vapor conveyance for 1) a Polarity Conversion Unit for non-destructive PFAS removal from soil, sludges, rechargeable galvanic filter media and objects, 2) a fluids treatment line for PFAS removal from water, brines, foams and colloids, and 3) an amphiphilic decontamination wand for PFAS removal from hard surfaces. The vapor emissions treatment system uses direct spray cooling to cool treatment gases where fluid chemistry causes pre-micellular aggregates/liquids crystals formation. Filtered aggregates are dried in a Brine Pot Evaporator for off-site disposal. Residual PFAS vapors are removed through a Vapor Phase Galvanic Separator where galvanic currents offer high energy interfaces of varying charges for monomeric PFAS self-assembly. The Polarity Conversion Unit assembly uses transportable flow through vessels, static geometry, high surface area, treatment gas temperature and velocity modulation to reduce thermal resistivity of the media. Treatment gas is sequentially routed around shaped vertical media beds where thermal energy disorganizes surface polarities (Gibbs free energy) disconnecting amphiphilic compounds/mixtures from the media. The fluids treatment line uses a Surface Excess Concentrator where a surface excess complex is created, removed and dried for off-site disposal. Treated bulk fluids exit from the bottom (below the surface) and are routed to the Aqueous Phase Galvanic Separator. Galvanic filter media is recharged in the Polarity Conversion Unit for reuse. Hard surfaces are decontaminated using the amphiphilic decontamination wand to disorganize surface polarity. Catalytic oxidation and granular activated carbon systems are also used to capture, destroy and measure classic contaminants and cleaved hydrocarbons from fluorinated precursors during treatment.

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.

A continuous flow granular/flocculent sludge wastewater process selects for granule biomass capable of nitrogen and phosphorus removal and controls granule size and concentration of granular and flocculent sludge for optimal nutrient, organic, and solids removal in a smaller footprint. It includes anaerobic, anoxic, and aerobic process zones, a high soluble biodegradable COD loaded first reactor in anaerobic or anoxic zones, a granular sludge classifier with recycle of underflow granular sludge to the first reactor, a secondary clarifier to settle flocculent sludge and particulates and recycle of flocculent sludge from the secondary clarifier underflow to an aerobic process zone. Wasting of sludge from the two separate recycle lines controls the bioprocess flocculent and granular sludge concentrations and SRTs. Bypass around and recycle flow to the classifier to maintain desired flow under various influent flow conditions aid control of granule size. On/off mixer operation of anaerobic and anoxic reactors may be used.
