multiple benefits
.avif)
Economical
Flow rates up to 1500 m³/h with limited OPEX (excellent maintenance and energy efficiency).
Easy to Maintain
Automated system with no need for heavy supervision.
Reliable and Robust
No clogging (free-flow treatment) and remote motors (outside wet zones).
Eco-friendly
Few (VAL INDUS) or no additives (VAL AQUA) for recoverable concentrated waste.
Compact
A vertical process that requires a small footprint.
Multi-functional
Three combined or separate functions: particle extraction, gas dissolution and degassing, and water circulation.

With a minimal footprint, VAL INDUS ensures compliance with discharge standards. It boosts sludge valorization for biogas production, achieving double the dryness rate. Remote monitoring guarantees safety and optimal performance.

Originally designed with pumps, sand filters, and UV treatments, we switched to VAL AQUA alone, cutting energy consumption by eight times and achieving superior water quality in filtration, purification, and oxygenation.

Just one month after commissioning VAL AQUA, we saw a noticeable improvement in water turbidity. The water became crystal clear, and all algae were eliminated."

"The VAL™ is the only system I've seen yet to accomplish all 3 functions:
1. Water circulation,
2. CO2 , N2 & O2 Mass transfer, and
3. Particle harvesting."
VAL SKID: PILOT TESTING, DEPLOYMENT, AND RENTAL OPTIONS
Coldep provides mobile pilot units in containerized or skid-mounted configurations. These allow for on-site testing and validation of technical decisions from the design phase, supplementing the preliminary lab tests conducted with the VAL PILOT.
