CATALYTIC OXIDATIONPatented process

Two-phase catalytic oxidation

Our own process for effluent that will not meet COD or colour limits. A first stage over a composite heterogeneous transition-metal catalyst, then a second over solid zero-valent composite metal that works by reduction and micro-electrolysis — which is what breaks the azo dyes and complex ring structures conventional Fenton leaves behind. The whole reaction is held near pH 6, so there is no acid dosing step and much less alkali afterwards, and dosing is set automatically against measured flow and load.

BIO-AUGMENTATION

In-situ upgrade, rescue & engineered cultures

Raising a plant's throughput and effluent quality without building new structures. We isolate specific strains, ferment them at our own base, and immobilise them on affinity biocarriers so the useful organisms stay in the tank instead of washing out. Metagenomic sequencing tells us what is actually happening in the sludge rather than what should be. This is the technology behind our low-temperature and high-altitude work — and behind restarting a biological system that has died.

HIGH-STRENGTH

High-strength organic wastewater

CSTR hydrolytic-acidification vessels to make stubborn organics biodegradable, followed by function-enhanced EGSB anaerobic reactors carrying volumetric loads of 20–25 kg COD/m³·d. Controlled external circulation keeps the reaction zone turbulent for mass transfer; the patented three-phase separator releases gas quickly and is simple to maintain. No separate biogas buffer tank, low sludge yield, and it keeps degrading when the influent is toxic.

PACKAGED / MBR

Small-town, hospital & camp sewage

Packaged and containerised works for places with no sewer network: towns, clinics, hotels, mining camps and estates. AAO-HM membrane bioreactors and AAO-DSF dynamic sludge filtration in a small footprint, plus a constant-level MBR that needs no sludge return line — which removes the pump and the operator decision that most often goes wrong on a small plant. Built modular, so units repeat rather than being redesigned each time.

WATER SUPPLY & REUSE

Process water, reuse & water supply

The clean-water side: ultrafiltration and reverse osmosis for boreholes, surface water and treated effluent going back into the process instead of into the ground. Multimedia and activated carbon pretreatment, softening and antiscalant dosing sized against your analysis. On African sites this most often follows the wastewater plant — reuse is usually the cheaper water.
