Rental & Mobile Treatment Plants

Temporary treatment capacity that keeps you compliant while the permanent solution is built.

Rental and mobile treatment plants are skid- or container-mounted units that can be delivered, connected and commissioned quickly to add treatment capacity for a defined period. They are used to keep a plant running during a retrofit, to cover peak seasonal loads, or to respond to an emergency without waiting for a permanent build. Because they use the same core technologies as fixed plants — filtration, adsorption and biological polishing — they can be matched to the exact effluent target you need to hold in the interim.

Where rental & mobile plants fit

A temporary plant is not a compromise — it is a way to de-risk a permanent decision. Instead of forcing a rushed capital project or risking non-compliance during construction, a mobile unit holds the required effluent quality while the permanent solution is engineered and built. It is equally useful for absorbing a known seasonal peak or covering the gap after an unexpected failure.

Container / Skid-Mounted Filtration

high

Pre-built filtration units delivered ready to connect, for temporary solids and phosphorus polishing.

Footprint: Modular
Complexity: Low
Advantages
  • Fast deployment
  • No permanent build
  • Scalable in modules
  • Returns after use
Limitations
  • Rental cost over time
  • Needs site connections
  • Defined-period solution

Mobile Advanced Polishing

medium

Containerised adsorption or biological polishing for higher-grade temporary treatment needs.

Footprint: Modular
Complexity: Medium
Advantages
  • Matches permanent targets
  • Flexible configuration
  • Bridges major upgrades
  • Emergency ready
Limitations
  • Higher rental rate
  • Commissioning time
  • Site-specific setup

Engineering Insight

The value of a rental plant is time: it separates the deadline to stay compliant from the timeline to build the right permanent solution. The design question is simply which processes the temporary unit must run to hold your target — and for how long — so the interim and permanent plans line up rather than compete.

For Existing Plants

If you are planning a retrofit, a temporary unit can keep the plant compliant throughout construction, removing the pressure that so often forces a hurried technology choice. A plant assessment ties the temporary and permanent solutions together so both are engineered around the same effluent target.
