Technical questions get a technical answer, usually within one working day. There is no sales sequence attached to asking.
Who we are
watertreatment.africa is the dissolved air flotation desk of AI-Spares, Hong Kong. We are an independent specification and supply desk working through vetted manufacturing partners, serving industrial and municipal clients across Africa. We are not a manufacturer, and we say so at the enquiry stage rather than later. More about how we work →
What to include
The more of this you send, the more useful the first reply will be. If you have none of it, say so — we will tell you what to sample and how to composite it.
- Industry, process and production rate
- Effluent flow: average m³/day and peak m³/h
- Analysis: TSS, FOG, total COD, filtered COD, pH range, temperature
- The discharge consent document
- Whether discharge is to sewer, to environment or to reuse
- Existing treatment and what it is failing to do
- Country and nominated port
Frequently asked questions
Will I be put on a mailing list if I ask a technical question?
No. A technical question gets a technical answer. If the answer is that flotation is the wrong process for your stream, that is what you will be told.
Do you charge for sizing or feasibility work?
Indicative sizing and proposal work is free. Detailed process design, pilot trials and independent expert review of a third party’s design are chargeable, quoted before any work starts.
Can you help with a plant you did not supply?
Yes, and it is a significant part of what we do. Bring us the analysis, the current chemical regime, the measured recycle flow and a photograph of the float, and in most cases we can identify the problem remotely before anyone travels.
