Products & Applications

One platform. Multiple applications.

Renew Water's CavOx technology is a single treatment platform that can be configured across multiple water treatment challenges and industries — replacing or significantly improving on conventional chemical-based approaches in each context.

RenewPool is Renew Water's first commercial product, applying CavOx to pool water treatment. It provides a complete replacement for UV and chlorination in commercial and residential pools — handling disinfection, residual requirements and water clarity in a single pass with no chemical addition. IAPMO-accredited lab testing (January 2026, California) confirmed E. coli reduction of log 9 exceeding both NSF Pool and EPA Drinking Water benchmarks, as well as 2x times better residual disinfectant than chlorine within approximately 25 minutes at a single tank turn.

  • Reduces chloramines — no eye or skin irritation for swimmers
  • No ongoing chemical procurement, storage, or handling
  • IAPMO-validated: exceeds NSF Pool and EPA Drinking Water benchmarks
  • Retrofit-compatible with existing pump and circulation systems
  • Reduces long-term operating cost versus conventional chlorination

Certification

UL — in progress  · IAPMO accredited test

Designed for high-turbidity, high-organic-load, hard to treat municipal and industrial wastewater streams where UV systems are significantly impaired. The electrocoagulation step first handles suspended solids, allowing oxidation and cavitation to work effectively in conditions that would render UV inoperable. Internationally accredited testing confirmed near-complete E. coli removal at 86 NTU.

  • Tested effective at 86 NTU — where UV performance drops sharply
  • Near-complete E. coli removal certified by internationally accredited independent laboratory
  • Simultaneous coagulation and disinfection in a single pass
  • No chemical addition; no disinfection byproduct formation
  • Applicable to dairy, food processing, and municipal streams

Integration

Inline with existing treatment infrastructure

Internationally accredited — independent trial

Cooling towers accumulate biofilm, algae, and calcium scale — typically managed with chemical biocides, algaecides, and descalants. CavOx replaces this with a single electrochemical treatment pass, eliminating chemical procurement and disposal burden entirely.

  • Eliminates biocide and algaecide procurement and handling risk
  • Electrochemical removal of algae and calcium scale buildup
  • Reduces Legionella risk through continuous oxidative treatment
  • Lower blowdown frequency and associated water waste
  • Simplified compliance with cooling water treatment regulations

Integration

Inline with cooling tower circulation loop

CavOx consolidates the entire RO pre-treatment train — coagulation, biological fouling prevention, and scale control — into a single chemical-free pass. Electrocoagulation removes suspended solids; electrochemical oxidation addresses biological fouling; hydrodynamic cavitation assists scale disruption.

  • No coagulant, antiscalant, or biocide chemical addition
  • Reduces membrane fouling — lowers pumping power and extends RO service life
  • Significantly simplifies the pre-treatment train and CAPEX
  • EC removes suspended solids and colloids in a single step
  • EO addresses biological fouling potential ahead of membranes
  • 50% reduction in pumping power and associated costs

CavOx can take source water to potable standard in a single pass, replacing the conventional multi-stage UV plus chlorination sequence. Independent internationally accredited analysis at a commercial bottling facility confirmed compliance with potable water standards over 8+ years of continuous operation. IAPMO testing shows results exceeding EPA Drinking Water benchmarks.

  • Independently certified to potable water standards at a commercial bottling facility (8+ years)
  • IAPMO results exceed EPA Drinking Water disinfection benchmarks
  • No disinfection byproducts — no THMs, HAAs, or chloramines
  • Effective in turbid source water without upstream pre-treatment
  • Applicable to decentralized and remote water supply contexts

Integration

Single-pass, scalable to required throughput

Internationally accredited · IAPMO accredited

IMO BWMC requires treatment of ballast water before discharge to prevent invasive species transfer. CavOx provides a chemical-free treatment pathway effective against crustaceans and organisms per the IMO D-2 standard, without any biocide requiring neutralization before overboard discharge.

  • Effective against crustaceans and organisms per IMO D-2 standard
  • No chemical biocide — no residual discharge in port
  • No neutralization step required before overboard discharge
  • Retrofit installation compatible with existing ballast systems
  • Simplified compliance pathway for vessel operators

Integration

Retrofit-compatible with existing ballast pump systems

Certification

IMO D-2 compliant pathway — in development
