Groundwater & Brackish Water Desalination

Turning brackish water into fresh supply. Saline aquifers are often written off as unusable. With SonixED™, even groundwater with high salinity range (TDS) can be transformed into a steady supply of fresh water. Our systems minimize pre-treatment, reduce scaling risks, and are built for remote, harsh environments where traditional desalination struggles.

Why SalinBloc™ for Salty Groundwater?

  • Wide Salinity Range: from 1.000mg/l to 20.000mg/l
  • Minimal pre-treatment: small setup, faster setup
  • Modular design: mobile or anchored installations
  • High recovery: down to 2% discharge
  • Proven in harsh sites: agriculture, mining, inland towns, etc.

Groundwater Contamination Removal

Removing harmful ions at the source. Groundwater contamination is a growing challenge, from heavy metals like arsenic to industrial pollutants. Conventional methods often rely on chemical dosing or complex treatment chains. SalinBloc™ uses selective ion extraction to deliver safe, clean water at the source, ensuring compliance with strict standards without adding chemicals.

Why SalinBloc™ for Polluted Groundwater?

  • Selective ion removal: arsenic, nitrate, lithium, heavy metals
  • No chemicals: cleaner, safer process
  • Regulation-ready: built for strict standards
  • Reliable quality: consistent safe water
  • Flexible use: rural wells, industry, energy sites

Hard Groundwater

Scaling and fouling under control. Many groundwater sources aren’t extremely salty but are packed with hardness, silica, or sulfates. These minerals clog membranes, drive up chemical use, and cut system life short. With SonixED™, fouling is prevented at the source, enabling high recovery without the need for aggressive pre-treatment.

Why SalinBloc™ for Hard Groundwater?

  • Stops scaling: effective against calcium, magnesium, silica
  • Less chemicals: ultrasound prevents fouling naturally
  • High efficiency: keeps recovery rates near 98%
  • Longer lifetime: membranes protected from deposits
  • Built for hardness: inland wells, mining water, industrial users

Smart Groundwater Monitoring & Management

Stay ahead with smart monitoring. Groundwater is dynamic — salinity shifts, contaminants appear, and demand changes. Without monitoring, systems can fail unexpectedly. HydroVolta integrates real-time sensors and predictive algorithms to track water quality, anticipate changes, and optimize performance providing constant output even with changing salinity. Operators gain confidence, regulators gain visibility, and communities gain reliability.

  • Predictive insights: anticipate changes early
  • Remote control: operate from anywhere
  • Lower downtime: smart maintenance alerts
  • Trusted oversight: regulators, industries, communities

GROUNDWATER • HIGH SALINITY & NITRATE

At a remote groundwater site, high salinity and nitrate levels made reuse challenging. SonixED™ delivers 95–98% recovery with only 2–5% brine, securing supply and meeting standards at low energy use.

  • 95-98% recovery
  • 2-5% brine volume
  • ~1.8 kWh/m³ energy
