Remote management: the key solution for wastewater treatment plant management
To manage the facilities in wastewater treatment plants and the wastewater treatment process, remote management is a valuable aid for operators, allowing them, among other things, to:
- Guarantee and monitor water treatment
- Optimise the treatment process
- Meet regulatory requirements related to self-monitoring
- Secure sites
- Reduce operating costs
- Guarantee the proper operation of the facilities
The treatments implemented vary according to the size of the station, the surrounding environment, the nature of the effluents, the surface area of the site, the discharge constraints, etc.

Wastewater plant management and automation < 3000 pop. equiv
A SOFREL S4W remote terminal unit Nouvelle fenêtre is sufficient for performing the purification process in small treatment plants. Typically, in an extended aeration activated sludge purification plant with around fifteen engines, the telemetry device, thanks to its process control suite, will be capable of managing the following elements: lift station, travelling screen, sand/oil separator, ventilation, clarification, recirculation, sludge extraction and sewage units.

Monitoring large wastewater treatment plants
Beyond a population equivalent of 3,000, wastewater plants become more substantial and integrate additional treatments (deodorisation, dephosphatation, sludge treatment, stormwater basin, etc.).
The purification process in these large treatment plants is often entrusted to Programmable Logic Controllers. The remote terminal units communicate with these PLCs and monitor correct functioning of the facilities, save all data required for operational purposes, generate operating reports, enable on-site or remote display of information, and supply self-monitoring data to the operator.
They also issue alerts in the event of malfunction, control and manage access to facilities, detect intrusions, and monitor levels of treatment products.

Level measurement and flow rate calculation in storage lagoons
A strongly growing trend in small rural localities in particular, lagooning involves relatively extensive basins receiving wastewater.
This water is treated in a biological and natural way. These sites rarely have an electrical power supply. For measuring input and output flows, the installation of a SOFREL data logger combined with a Venturi flume is an excellent solution for discharged water tracking and self-monitoring requirements.
The data logger can be connected to a rain gauge to record local rainfall levels, in parallel to the flowrate. Lastly, for these applications, the data logger can also control an autonomous sampler.
