Water is a key raw material in pharma and chemical manufacturing processes. Consistent and high-quality water is required for production processes, and complex wastewater is generated once the pharmaceutical products and chemicals are produced. More and more producers are implementing strategies to minimize the water they draw from external sources, meaning that less wastewater is discharged and more wastewater is being reused as process water. In this way, water reuse provides savings through the reduction of both fresh water and waste disposal costs.
The chemical industry generates wastewater containing toxic, mutagenic, carcinogenic materials and difficult to biodegrade components. The same happens in the pharmaceutical industry, where in addition, the quality of process water is critical and has to meet the highest sterilization standards and protocols.
Pharma and chemical industry wastewater varies in flow and composition, depending on the production rate and the final product manufactured. This implies that the characteristics and peak loads of the wastewater are variable over time. Pharma and chemical wastewaters may contain:
Pharma and chemical industries all over the world face tremendous environmental regulatory challenges in treating their wastewater effluents. The main pollutants are organic chemicals, some of them toxic and difficult to biodegrade. Active pharmaceutical ingredients (APIs) are also known to have a detrimental impact on the environment, due to the fact that they are bio-refractory and persistent, tending to accumulate in the environment.
Wastewater treatment has been traditionally based on biological processes. However, there is an increased awareness of the limitations of conventional technologies for addressing the required removal of contaminants and the current discharge requirements.
Berghof’s MBR technology has come up as one of the best available technologies for handling the challenging streams from the pharma and chemical industries. The specific operational conditions – mainly linked to high MLSS in the bioreactor and high SRT– allow the growth of highly specialized biomass able to degrade the slowly biodegradable pollutants. Inhibition by toxic compounds is also avoided to a large extent.
Direct filtration also plays a significant role in water/wastewater management within the pharma&chemical industry. Tubular UF is applied as a direct filtration system for removing specific contaminants and also for brine recovery. High-quality deionized water is required for producing chemicals and pharmaceuticals. As a result, significant volumes of brine are produced by the use of nanofiltration and reverse osmosis systems. Here, Berghof tubular UF is applied coupled with a chemical pretreatment for brine recovery in the scope of ZLD strategies.
Made in a state-of-the art LEAN-production facility, with highly-trained production personnel and materials of the highest quality.
With 50 years of experience and more than 2.000 projects worldwide, Berghof Membranes is the leading manufacturer of high quality tubular ultrafiltration membranes.
50 years of experience and more than 2.000 project references across the globe.
