Pipe System with Intelligent Control
Patented pipe system and control method optimize fluid routing, prevent dead zones, and enable automated operation, improving reliability and energy efficiency in treatment plants.
Wastewater Treatment Control Software
The proprietary software V1.0 integrates monitoring and logic control, allowing user‑friendly “foolproof” management, remote access, and precise adjustment of treatment parameters.
Alkali Recovery and Recycling
Several utility patents cover alkali recovery from industrial streams, reducing chemical consumption, minimizing waste, and supporting sustainable operations in textile and chemical processes.
DAF Air Dissolution Assembly
The patented air dissolution unit for DAF efficiently generates microbubbles, enhancing oil and solids removal, improving clarification, and reducing energy input in pretreatment stages.
Hydraulic Screen Classifier
This utility patent separates solids by size using water flow, providing effective grit and debris removal, protecting downstream equipment, and simplifying sludge handling.
Liftable Aeration System
The patented liftable aeration device allows easy maintenance and replacement without draining tanks, ensuring uniform oxygen transfer and long‑term operational stability.
Five Core Business Sectors
River international focuses on five core sectors: pharmaceutical, food, chemical, industrial park wastewater, and low-carbon aquaculture with tailwater treatment.
Patented Pharma Wastewater Breakthrough
Patented technologies tackle high-strength “three-high” pharmaceutical wastewater under space constraints, winning provincial recognition.
DAF Pretreatment for Food Wastewater
River international applies coagulation‑DAF to remove emulsified oil and suspended solids in Food projects, reducing organic load before UASB and MBR, ensuring stable, compliant effluent.
High-Capacity Biological Odor Control
Biological deodorization systems handle up to 50,000 m³/h for industrial parks and recycling economies.
MBR Ensures High‑Quality Effluent for Oily & Pharma Wastewater
River international deploys MBR combining biological degradation with membrane filtration, treating high‑COD oily and pharmaceutical streams. It produces reusable permeate, minimizes sludge, and maintains stable operation under variable loads.
Expert Team with Strong Technical & Financial Backing
River international team leverages two strategic investment firms and an in‑house design institute, uniting seasoned engineers and patent experts to tackle complex industrial and aquaculture wastewater projects.
