💧 Granular Activated Carbon Technology
Ozonated Water Backwash Regeneration
US 9,375,663 B2
The foundational technology that started our GAC innovation journey. This patent covers the use of dissolved ozone in backwash water to simultaneously sanitize and regenerate granular activated carbon filter beds. By fluidizing the filter media and exposing each particle to ozonated water, the method achieves both microbial control and restoration of adsorptive capacity in a single operation—eliminating the need for costly thermal regeneration or chemical treatments.
80% capacity restoration In-situ regeneration Bacterial control Minimal downtimeBack-and-Forth Washing Process
US 11,891,311 B2
A breakthrough in water efficiency for filter regeneration. This patent introduces bidirectional flow cycling between paired vessels or between a filter and holding tank, enabling prolonged contact between treatment agents and filter media while dramatically reducing water consumption. The back-and-forth method achieves thorough regeneration using as little as 2 bed volumes of wash water—compared to 20+ bed volumes with conventional backwashing.
Ultrasonic Regeneration with Back-and-Forth Washing
US 12,428,320 B2
The evolution of our regeneration technology combining ultrasonic energy with the water-efficient back-and-forth washing process. Ultrasonic transducers positioned within the filter bed deliver targeted acoustic energy that enhances desorption of contaminants from GAC pores. When combined with our bidirectional washing method, this approach achieves superior regeneration results with minimal water usage—ideal for facilities with limited water availability or stringent discharge requirements.
Selective TOC Removal and PFAS Management System
Patent Pending
Our most advanced GAC technology addresses the critical challenge of PFAS contamination in drinking water. This system exploits differential binding energies to selectively remove competing organic matter (TOC) at ambient temperature while retaining PFAS on the carbon—extending GAC service life 4-6x. The optional integrated PFAS management module uses foam fractionation and electrochemical destruction for complete PFAS mineralization, achieving zero liquid discharge. Reduces operating costs by 80-90% compared to conventional GAC replacement.

🔄 Reverse Osmosis Technology
Intelligent RO Process Control and Optimization
WO 2024/236353 A1
A sophisticated control system that brings artificial intelligence to reverse osmosis operations. This international patent covers methods for real-time optimization of RO system parameters including pressure, flow rates, and recovery setpoints. The system continuously adapts to changing feed water conditions, membrane performance, and operational constraints—maximizing efficiency while protecting membrane integrity. Ideal for facilities seeking to reduce energy consumption and extend membrane life through intelligent automation.
Flow Reversal Closed-Circuit Reverse Osmosis
US 12,472,467 B1
A breakthrough combination of Closed-Circuit RO (CCRO) batch concentration with Flow Reversal RO (FRRO) technology. This patented system achieves 9-15% higher recovery than conventional RO by combining batch concentration to higher TDS levels with periodic flow reversal that disrupts scaling kinetics and equalizes membrane stress. The alternating lead/tail positions prevent any single membrane element from permanent high-concentration exposure, extending membrane life while enabling operation on difficult, scaling-prone waters.
Twin-Vessel FRCCRO Configuration
Patent Pending
The next evolution in FRCCRO technology featuring a twin-vessel architecture with 30 three-element vessels instead of conventional 15 six-element vessels. This configuration delivers port-to-port membrane connections that reduce system volume by 26%, simplified valving with only two 3-way T-port valves, and further recovery improvements on difficult waters. The compact design reduces capital costs by 20% while achieving the highest recovery rates in the industry—up to 96% on suitable feedwaters.
