The client challenge
Kiira Motors is a pioneering Ugandan manufacturer of electric transport vehicles. Its factory, located in Uganda (East Africa), produces electric buses for the African market and generates complex industrial effluents from the surface treatment baths used in the manufacturing process.
These effluents, loaded with suspended solids (TSS), heavy metals and variable pH, required rigorous treatment before any discharge into the environment, in compliance with Ugandan regulatory requirements.
Kiira Motors therefore needed a solution capable of:
- Treating all effluents from the surface treatment baths
- Reducing TSS and heavy metals and correcting the pH of discharged water
- Meeting local discharge standards in a demanding geographic context, far from European suppliers
- Integrating into a new factory with installation and operational constraints specific to the African environment
To meet this challenge, Kiira Motors turned to Nomado to design and deliver a complete, reliable and remotely operable treatment unit.
The Nomado solution
To support Kiira Motors, Nomado designed, built and commissioned a fully containerised industrial effluent treatment unit, adapted to the site constraints and local regulations.
Our approach was built on three core commitments: technical robustness, operational autonomy and remote monitoring.
A complete, multi-pollutant treatment process
The unit deployed by Nomado treats industrial effluents at a flow rate of 25 m³/h through a full sequence of treatment steps:
Pre-treatment
- Oil separation: removal of hydrocarbons and grease prior to treatment.
- Lift stations: hydraulic management of incoming flows.
- Buffer tanks: flow regulation and effluent homogenisation.
Physico-chemical treatment
- Coagulation, flocculation and settling for TSS and heavy metal removal.
Tertiary treatment
- Sand filtration: removal of residual suspended solids.
- Activated carbon filtration: capture of micropollutants and trace metals.
- Final pH correction: ensuring compliance of the final discharge.
Sludge management
- Sludge thickening using filter big-bags: compact solution with low maintenance complexity, adapted to the local context.
A modular solution, delivered turnkey
Containerised unit — 2 × 20-foot High Cube containers
- Treatment flow rate: 25 m³/h, sized for the full production activity of the factory.
- Prefabricated solution, shipped and commissioned directly on the Ugandan site.
- Compact footprint and rapid installation with no heavy civil works.
Smart, autonomous monitoring
- Control panel with remote connection: supervision and remote intervention from France, reducing reliance on local maintenance expertise.
- Scalable system, adaptable to future increases in production load.
