As an industry leading provider of equipment to the dairy and food processing industry, at Membrane System Specialists, Inc. we are capable of designing and manufacturing custom fluid separation systems for a variety of applications. Fluid separation systems are used to remove suspended particles, microorganisms, fats, proteins, or carbohydrates from the raw milk or other feedstock streams. Different membranes are used to effectively remove each type of particle based on size. The systems we produce are capable of removing particles from as large as 10 microns to less than 0.001 microns.

The first step of the design process is a complete characterization of the customer’s feedstock and desired final product. Given the specific feedstock volume and composition, a separation system is designed with the necessary microfiltration, ultrafiltration, nano filtration, or reverse osmosis system to create the needed streams for further processing. All equipment is manufactured to the highest quality and sanitation standards using durable materials that are easy to clean and require minimal maintenance. During the design process, our engineers are able to rapidly respond to any changes that may occur as a result of customer request. The controls and mechanical components we use are the highest quality in the industry and are specifically selected for their ability to endure harsh operating environments.

In addition to design and manufacturing, our team provides installation, commissioning, training, and full support throughout the life of the equipment. Membranes typically must be replaced once every 12 to 18 months to maintain maximum separation efficiency. We can provide replacement membranes quickly to ensure customers’ needs are met. All designs are custom, but are based on proven filtration processes that have been industry tested during in-house pilot programs and within the dairy industry. Our lead times are among the fastest in the industry for custom systems and vary depending on the scope of the project, with most lead times averaging 8 to 16 weeks.
