CATAQUA™ is Nippon Shokubai’s advanced Catalytic Wet Air Oxidation (CWAO) technology for the treatment of industrial wastewater containing high concentrations of organic contaminants and other difficult-to-treat compounds.
By combining proprietary catalysts with oxygen from air under elevated temperature and pressure conditions, CATAQUA™ efficiently converts pollutants into harmless substances such as carbon dioxide, water, nitrogen and sulfates. The technology provides a reliable and sustainable alternative for wastewater streams that are not suitable for conventional biological treatment alone.
Developed and continuously improved by Nippon Shokubai, CATAQUA™ helps industrial companies reduce their environmental footprint, improve wastewater treatment performance and support regulatory compliance.
Key Features
- High Treatment Performance
CATAQUA™ achieves highly efficient destruction of refractory organic compounds and other persistent contaminants, significantly reducing COD, toxicity, colour and odour. - Energy-Efficient Operation
Unlike thermal incineration, CATAQUA™ operates at moderate temperatures. The exothermic oxidation reaction generates heat that can be recovered and reused within the process, reducing operating costs and CO₂ emissions. - Minimal Secondary Waste
The catalytic oxidation process converts pollutants directly into harmless end products while minimising the generation of secondary waste streams and unwanted by-products. - Proprietary Catalyst Technology
At the heart of CATAQUA™ is Nippon Shokubai’s proprietary catalyst technology, designed for long-term stability, high activity and reliable performance under demanding industrial conditions.
Applications
- Chemical Manufacturing
Treatment of highly concentrated wastewater containing alcohols, aldehydes, carboxylic acids, phenols, amines and other refractory organic compounds. - Petrochemical and Refinery Operations
Effective treatment of spent caustic streams and wastewater containing sulfides, thiosulfates and other reduced sulfur compounds. - Industrial Manufacturing
Suitable for wastewater generated by sectors such as specialty chemicals, electronic materials, dyes, textiles, food processing and other industries where conventional treatment technologies face limitations. - Pre-Treatment and Load Reduction
CATAQUA™ can be applied as a stand-alone treatment solution or as a pre-treatment step to significantly reduce organic load and improve the performance of downstream biological treatment systems.
Why CATAQUA™?
CATAQUA™ enables industries to transform challenging wastewater streams into manageable effluents through a combination of proven oxidation chemistry, proprietary catalyst technology and decades of wastewater treatment expertise. The result is a cleaner, more sustainable and cost-effective approach to industrial wastewater management.
