In simple terms, bioprocessing is the use of microbes to manufacture useful products. Those useful products might be biofuels, textiles, alternative meats, specialty chemicals, or numerous other options.

Bioseparation refers to the separation and purification of a wide range of products produced via biological processes. The separation of biological products is typically difficult, involving a multi-step process, and the cost of separation can be a substantial portion of overall manufacturing cost. Bioprocessors may find that with conventional bioseparation, they cannot manufacture at scale or expand production while meeting regulatory requirements and profitability goals. There is a solution to these challenges on both the downstream processing and wastewater treatment sides of the bioprocessing equation: ZwitterCo Z-BIO membrane elements. Compared to current treatment options, processes using ZwitterCo superfiltration (SF) membranes may offer benefits, including lower cost of ownership, smaller footprint, lower energy costs, reduced cleaning costs, longer uptime between cleaning cycles, and water reuse.

  • Downstream Processing
  • Wastewater Treatment

The goals for downstream processing include isolating target molecule(s), removing contaminants, and increasing product concentration. Current treatment methods use centrifugation, membranes, chromatography, and crystallization to meet these goals. However, bioprocessors experience challenges with these methods such as cutoff precision, product loss, low throughput, and frequent cleaning.

ZwitterCo SF membranes offer unprecedented fouling resistance, intrinsic pore uniformity, and permeance recovery. This results in higher purity product, higher product yield, increased throughput, longer uptime, and lower CIP costs, which saves water and energy.

Waste Streams as Value Opportunity

Water is a critical part of many industrial processes, but using freshwater comes at a cost for the business, as well as the environment. When possible, treating process wastewater for use throughout the plant can be a good cost- and environment-saving option. ZwitterCo now has an economical solution to help bioprocessing businesses better manage their wastewater streams: Z-BIO membrane elements.

Another, sometimes hidden, resource in bioprocessing product processing is organic product recovery, such as nutrients, proteins, and high value molecules. For some, this generates a purified mixture that enables higher product quality and yield or turns a discharge cost into revenue by creating a saleable byproduct.
