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.

"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.
