Association of Three Co.,Ltd. is a manufacturer of equipment for the “environmental industries” (the Three in the company name are earth, air and water, not people!).
We started this company in 1993 and have built it into a successful organization supplying equipment for water and wastewater treatment throughout Asia and beyond. We have an excellent staff and workforce, many of whom have been with the company for over 20 years, and we make technically superior equipment developed by expert knowledge. We are flexible and innovative, seeking to continuously develop our capabilities.
We design and fabricate equipment to suit your particular requirements. Our main products include water, wastewater, and solid waste treatment systems such as fine and coarse screens, air diffusers, clarifiers, DAF plants, trommel screens, composting facilities, biogas plants, and more. We also undertake custom manufacturing based on client needs.
Our equipment is high quality and competitively priced. We have achieved ISO 9001 certification since 2000 and were re-certified under ISO 9001-2015, reflecting our commitment to consistent quality and continuous improvement.
