ARBOK-Phosphate

Overview

ARBOK-Phosphate is a zero-waste technology for deep-vacuum separation and reuse of phosphate-industry waste, including streams contaminated with radioactive nuclides. Instead of filtering or neutralizing, it physically pulls contaminants apart into pure, reclaimable fractions. It handles phosphogypsum including radioactive gypsum, acidic fertilizer-plant wastewaters, fluoride and HF sludges, contaminated sulfuric and phosphoric acids, and radionuclide-rich tailings containing Ra-226, uranium and thorium. There are no membranes, no filters and no reagents, and every output is either market-usable or fully stabilized.

Applications

Primary use cases: reprocessing radioactive phosphogypsum from legacy sites; recovery of a portfolio of commercial-grade acids from phosphate mining and fertilizer effluent; remediation of acid-waste and radwaste ponds.

Industries and users: phosphate and fertilizer producers; mining-waste and radioactive-waste operators.

Scale: 100–400 t/day per modular containerized unit.

Operating Principle

Low-temperature phase-change vacuum mechanics pull the feed apart and reclassify every component without membranes, filters or reagents. Water, a portfolio of recoverable commercial-grade acids, and an inert solid residue are separated, while radionuclides are stabilized in a solid matrix for safe long-term handling. The build is acid- and radiation-resistant throughout, using advanced corrosion- and radiation-resistant engineering materials selected for long-term exposure to aggressive process streams.

Limitations: radiation-handling permitting; cost of acid-resistant materials; residue and acid offtake arrangements.

Key Parameters

| Parameter | Value |

|---|---|

| Capacity | 100–400 t/day per container |

| Energy consumption | 2–4 kWh/tonne (vs 5–15 for RO) |

| Footprint | Modular containerized unit |

| Chemical resistance | Strongly acidic, fluoride-bearing process streams and heavy-metal-laden waste |

| Radiation removal | up to 99.5 % (Ra, U, Th) |

| Waste | zero brine, zero emissions, <0.2 % inert solids |

For a representative feed, the process yields a majority output of clean, reusable water, together with a portfolio of commercial-grade acids recovered as separate marketable streams, and a small residual fraction of inert, stabilized solid.

Architecture and Components

Acid- and radiation-resistant vacuum phase-change chamber built from advanced corrosion- and radiation-resistant engineering materials; acid-fraction recovery and storage; water condensate circuit; inert-solid and radionuclide stabilization unit; inline water analytics with automatic shutdown. Fully containerized and autonomous.

Advantages

Technical: no brine, no membranes and no filters; handles aggressive acids and radionuclides that defeat conventional treatment; every stream becomes either product or safely stored solid.

Economic: 2–4 kWh/tonne; converts stored liabilities into saleable acid fractions; containerized deployment requires no plant overhaul.

Environmental: zero emissions, under 0.2 % inert solids, radionuclides stabilized rather than dispersed.

Strategic: resolves the phosphogypsum and radwaste burden while recovering a portfolio of strategic, commercial-grade acids in the same operation.

Integrations

Co-locates with fertilizer plants, phosphate mines and legacy phosphogypsum or radwaste ponds. Built-in AI compliance monitoring. Pairs with ARBOK acid and brine units.

Deployment & Operation

Steps: waste characterization → module sizing → containerized installation → commissioning. Operation is fully autonomous with inline analytics and automatic shutdown on deviation, requiring minimal staffing.

TRL

TRL 7 (confirmed by Michael). Pilot-tested in near-operational environments across major phosphate-producing regions of North America, Russia, South Asia and North Africa. Remaining: full industrial deployment and radioactive-waste certification.

Market Potential

Phosphogypsum is a vast global liability, radioactive in many regions, with no standard commercial reuse — and radwaste and acid-effluent rules are tightening. Strong fit at phosphate-fertilizer hubs and legacy sites in the United States, Russia, India and the MENA region.

Typical Project Economics

Revenue comes from a portfolio of recovered commercial-grade acids together with clean water, while the liability side — storage, monitoring and radwaste handling — converts into product. Energy cost is 2–4 kWh/tonne; CAPEX is modular per container. Site economics depend on the acid and radionuclide profile of the specific feed.

Risk Factors

Radiation-handling permitting and public perception. Cost of acid-resistant materials. Securing offtake for recovered acids and residue. Conservative adoption culture in the phosphate industry. Scale-up validation from pilot to full industrial deployment.
