US9061221B2 - Phosphate recovery from sludge - …
A process for recovering reusable materials, in particular phosphate, from sewage sludge products, namely sewage sludge, sewage sludge ash or sewage sludge slag, by extraction, in which a suspension of the sewage sludge product is produced in water, alcohol, water-alcohol mixture or an aqueous solution, gaseous carbon dioxide (CO 2 ) or supercritical carbon dioxide (scCO 2 ) is introduced as ...
Thermal treatment of sewage sludge and …
Our patented process for phosphorus recovery consists in a wet stone leaching step with an integrated acid recovery and the selective separation of phosphoric acid. The raw phosphoric acid is filtered out from the undissolved ash particles. Customised qualities of phosphoric acid are obtainable. The yield of phosphorus recovery is about 60 to 80 %. The mass reduction of the sludge ashes is …
Phosphorus recovery // REMONDIS Sustainability
One of REMONDIS latest developments is its patented TetraPhos process. It fits into the chain of wastewater treatment, thermal treatment and phosphorus recovery perfectly. A sustainable system that fully closes the material life cycle of phosphorus for the very first time. But thats not all: TetraPhos
PARFORCE – an innovative phosphorus-recovery …
The recovery of pure phosphoric acid from sewage-treatment sludge and other phosphate-containing waste – as implemented in the PARFORCE process – for specific applications is significantly more advantageous than merely again producing a fertiliser. In addition, the corresponding phosphorus recyclates are also dependent on approval under the Fertiliser Ordinance and on market acceptance ...
Energy Surplus Wastewater Treatment Plant with …
It was based on the use of the LysoTherm ® technology for thermal disintegration of sludge, the LysoGest ® process for separate digestion of primary and secondary sludge, and the patented and proprietary technology EloPhos ® for phosphorus recovery from the sludge flow.
COMBINED PHOSPHORUS REMOVAL AND RECOVERY
the operational mode. The process is based on removal followed by phosphorus recovery as calcium phosphates. In order to secure the biological phosphorus removal internal production of organic acids is necessary as the alternative to use acetic acid is costly. Chemically bound phosphorus may be released by combined thermal and acid treatment followed by phosphorus recovery…

25.01.2015 · In the process of chlorination, monazite is mixed with charcoal and heated at 900 °C , . Present stone is focused on the development of an effective process for the separation of phosphate and recovery of REMs from monazite. Systematic studies for thermal decomposition of Korean monazite for phosphate removal using soda roasting followed by water leaching is discussed. Additionally, acid leaching of the roasted mass is also studied…
STRUVIA Phosphorus Recovery and Harvesting …
Struvia™ Phosphorus Recovery and Harvesting uses a patented mixer, TurboMix™, in combination with lamella settlers to produce and separate struvite crystals from the wastewater within a single reactor with a small footprint, making it an economical phosphorous recovery process.
A review of phosphorus recovery from different …
02.09.2019 · Technologies based on phosphorus recovery from sewage sludge and thermal products, such as struvite and hydroxyapatite recovery, gained popularity more than 10 years ago. However, the migration and transformation of P in thermal treatment processes and the specific influence of the speciation of P in the thermally treated products on subsequent leaching, extraction or direct utilization are still problems to be solved urgently…

ePhos – Electrochemical phosphorus recovery - …
Fraunhofer IGB has developed and patented a novel process to recover ammonium (NH 4+) and phosphate (PO 43–). In this electrochemical process with a magnesium electrode, NH 4+ and PO 43– are precipitated as struvite. This new process has the advantage that no chemicals such as MgCl 2 or NaOH need to be added for the precipitation process.
RecoPhos and Other Thermo-Chemical Processes for the ...
RecoPhos and Other Thermo-Chemical Processes for the Recovery of Phosphorus from Sewage Sludge. In modern sewage treatment plants (STP), about 90 % of the influent’s phosphorus can be re-moved via stone and/or biological processes. This entire amount is found in the sludge and, after thermal treatment, also in the ashes. If sewage sludge is mono-incinerated, the resulting ashes …
