Chemicals & Petroleum

The composition of wastewater from chemical plants varies widely. Sustainable treatments of effluent streams produced by chemical and petroleum industries are typically problematic, due to the complex compositions of pollutants, low biodegradability, and toxic matters. Nowadays, high salinity (5–25% chloride and/or sulphate)  represents a major challenge in the biological treatment of chemical and petroleum wastewater. High salinity levels can render traditional biological and chemical treatment technologies ineffectual and prohibitively expensive. Organic pollutants in effluents can cause serious problems in the operation of MVR and membrane systems for salts' removal.

Since the 1990s, Woxford has been working on solutions and has developed a wide range of technologies to address the most complex of challenges in this field.

1998

Glyphosate Wastewater Treatment 

2008

Acetone & Butanol Wastewater Treatment 

The first successful application of Woxford's 1st-Gen advanced anaerobic bioreactor in the treatment of glyphosate wastewater at over 91% COD removal efficiency and 9.6 kgCOD/m ·d organic loading rate.

2015

Sebacic Acid Wastewater Treatment 

Woxford developed an enhanced aerobic treatment technology to address the challenge of high salinity.
It has been employed in the disposal of sebacic acid (decanedioic acid) wastewater treatment.​

Influent: COD: 3,000–4,000ppm

              Phenol: 200–300ppm               

              Sulphate: 8–10%w/w
Effluent: COD: <100ppm, Phenol: ≤2ppm

Sulphate is recovered from the treated effluent by using MVR technology.  

2015

Petroleum Wastewater Treatment 

Woxford successfully incorporates anaerobic treatment technology in the treatment of petroleum wastewater containing metalworking fluids, coolants and lubricants. A new process is developed which combines the latest advanced anaerobic bioreactor technology with our advanced membrane technologies. It significantly increases the treatment efficiency of petroleum effluent, and reduces disposal costs.

2017

Cellulose Wastewater Treatment 

In 2017, Woxford has a significant breakthrough in employing anaerobic treatment process in the disposal of cellulose wastewater, and obtains several major contracts. Wastewater treatment plants are currently under construction, and our website will be updated with real-time performance data of our technology in full-scale projects, as soon as this is available.
