The client challenge
HTS BIO is a laboratory based in Gémenos (13), specialising in the design and manufacture of ecological cleaning and maintenance products. Its production activity involves industrial centrifuges whose washing operations generate wastewater that must be treated before any discharge into the environment.
These wash waters present chemical characteristics requiring a pH inactivation and neutralisation step before discharge, in compliance with the discharge standards applicable to industrial installations of this type.
HTS BIO therefore needed a solution capable of:
- Treating centrifuge wash water at a flow rate matched to the production schedule
- Neutralising effluents and ensuring their compliance with applicable discharge standards
- Integrating into a laboratory environment with a small footprint and straightforward operation
To address this challenge, HTS BIO turned to Nomado to design and commission a compact, operational treatment unit.
The Nomado solution
To support HTS BIO, Nomado carried out the design study, then built and commissioned a compact treatment unit entirely dedicated to the neutralisation of the factory's wash waters.
Our approach was built on three core commitments: compactness, simplicity of operation and regulatory compliance.
A treatment process based on inactivation and neutralisation
The unit deployed by Nomado treats wash water at a flow rate of 7 m³/h through a closed-loop neutralisation process:
Feed and neutralisation
- Feed pump: controlled introduction of wash water into the unit.
- Treatment tank fitted with an agitator: continuous homogenisation to ensure reagent effectiveness.
- 2 reagent injection systems: precise dosing for neutralisation and effluent inactivation.
Control and regulation
- Recirculation loop with pH control: continuous monitoring of treated water quality before discharge authorisation.
- Human-Machine Interface (HMI): intuitive unit control by operators without specialist technical skills.
A modular solution, delivered turnkey
Compact containerised unit
- Treatment flow rate: 7 m³/h, matched to the laboratory's production schedule.
- Fully prefabricated solution, delivered and commissioned on site by Nomado teams.
- Mobile and relocatable unit, adaptable to changes in requirements or site.
Results achieved
- Effluents compliant with environmental discharge standards.
- Controlled investment thanks to the modular and compact approach.
- Scalable system, capable of absorbing future increases in treated volumes.
