Dal Prete Dettagli

Dal Prete is an Italian company that has been designing and manufacturing water treatment solutions for stone working processes since 1964. 

With Dal Prete’s automated systems, you can almost completely eliminate the cost of recharging your company’s water system, by reusing high-quality clarified water for your processes.

In addition to the great financial savings, the system also has a hugely positive environmental impact.

At a glance, the level of water clarification achieved by these plants:

Extends the life of processing tools by up to 20%
Saves you up to 30% on water consumption
Reduces cost of disposing residual sludge by up to 50%
Greatly benefits the environment by conserving 90% of water used and allowing waste material to be disposed of in an environmentally responsible manner


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

1. 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.

2. Water Testing

The supply of the plant comes with a support phase for the correct management of the chemical agents to be used. We perform a dedicated service for testing your water, alongside Dal Prete by checking:

Choice of coagulant and flocculant that’s most suitable for you
Correct mixing of coagulant and flocculant
Correct dosing of the mixture according to the raw materials you process

3. After-Sales Consulting

We’re available after the initial installation period for the supply of spare parts, accessories, coagulant and flocculant, assistance and continuous training, and speedy resolution of malfunctioning problems.
