Our Process

Working alongside Dal Prete, we follow a 3-step process to ensure you’re up and running with the best system for you!


Company Analysis

We’ll have a preliminary consultation with you, where we’ll calculate your water consumption by finding out what kind of activity you perform, what materials you work with and which machines you own.

If you already have a clarification system:

We are interested in understanding the problems you encounter in order to integrate our solutions and maximise what you currently use.

If you’re new to wastewater treatment plants:

We’re able to implement the solution best suited to your needs.

  • Correct dosing of the mixture according to the raw materials you process
