Fluoridite: ALIT’s solution for stable fluoride removal in industrial wastewater
Managing fluorides in wastewater, especially in the aluminium and glass treatment sectors, is a constant technical and regulatory challenge. In Italy, the legal limit is often set at 6 ppm, while in some countries it can go as low as 2 ppm. Consistently staying within these limits is anything but easy.
Why fluorides are a real issue
During surface treatment processes, aluminium and glass release fluorides into wastewater streams. These compounds are hard to remove effectively, especially without disrupting the plant’s chemical-physical balance.
Fluoridite, a concrete ally
To address this challenge, ALIT Technologies developed Fluoridite, a specific chemical treatment designed to reduce fluoride levels in industrial wastewater, easily integrable into existing systems without modifying the current layout.
In real-world conditions, with initial concentrations around 50 ppm, Fluoridite has proven effective in lowering fluoride levels to about 3 ppm, with further improvements possible through fine-tuning. The product dosage is directly proportional to the water flow rate, making the process easy to calibrate and manage, even with fluctuating loads.
A complete technical approach
Fluoridite is developed and validated entirely in-house, through a process that includes:
- In-depth analysis of the customer’s existing wastewater treatment cycle,
- Lab testing to replicate real operating conditions,
- On-site dosage setup to ensure performance and compliance.
Strict control over raw materials, production batches, and final product performance guarantees quality, reliability, and regulatory compliance.
Tangible benefits
Fluoridite ensures stable and repeatable fluoride reduction, fully compatible with existing industrial systems. It’s a precise response to a real need, not a one-size-fits-all product, and it solves the problem without disrupting existing processes.
