The coffee industry – with production characteristics that generate highly complex and difficult-to-treat wastewater in the food and beverage sector – contains high levels of organics (BOD, COD), caffeine, suspended solids, many organic acids, and seasonal variations. In particular, the color level in coffee wastewater ranges from 6,000 to 13,000 Pt-Co, which is extremely high – one of the most challenging characteristics to treat in the coffee industry. This requires a treatment system with customized design, advanced color treatment technology, and integrated technical solutions. Coffee wastewater is a major challenge for businesses in this field.
As the world’s second-largest coffee exporter, Viet Nam is home to leading coffee corporations – the true “Coffee Kings”. To ensure stable production and sustainable development, a reliable wastewater treatment partner with proven capacity is essential. And the consistently chosen partner is Duong Nhat – Viet Nam’s No. 1 EPC General Contractor in environmental technology, wastewater treatment, water treatment, and wastewater reuse – Proud to be a Viet Nam Value Brand.

Duong Nhat has also been selected as the EPC General Contractor for the “Wastewater Treatment Plant of TaTa Coffee Processing Factory, Phase 2, Binh Duong” invested by TaTa Coffee Viet Nam Co., Ltd.
To effectively treat coffee wastewater – which is complex and rich in organics – requires not only modern technology but also practical experience, contractor capacity, and tailor-made design solutions for each factory.
