We want to do better.

To do that, we regularly seek feedback from customers regarding the challenges they face within their unique applications.

That insight returns to our product development team and they go to work figuring out how to incorporate it into future products.

We recently set our sights on a new product design in our skid mounted membrane filtration systems after receiving feedback on the current cooling method, which utilizes an in-tank coil.

• Customers told us they lost valuable processing time to cleaning all surfaces of the coil.
• Others struggled to reliably reach their application’s uniquely low temperature requirement because of the relatively low surface area of the chiller coil.
• Some of our customers work with such low feed volume that the chiller coil is ineffective given it’s proximity in the tank relative to the feed.

We developed a solution you might find cool. We definitely do.

Tissue engineering is a field of regenerative medicine aimed to mend and restore function to damaged tissues (1), where tissue is generated outside the body on external scaffolds. Damage to tissues can result from injuries like burns or wounds, or chronic illnesses like cancer or diabetes. In the body, cells that make up tissues are connected by a matrix, which provides a scaffold support and facilitates cell communication and nutrient exchanges. When artificial tissues such as skin or cartilage are grown outside the body, a cellular scaffold must be engineered to support the tissue structure and function. Such scaffolds can be designed from different materials depending on the served intention of one of the following purposes: cell attachment, cell delivery and retention, nutrient delivery, or exert influence to modify cell phase behavior. For example, growing artificial skin, which was approved for medical use in patients in 1996, works best on a semipermeable polycarbonate scaffold with a pore size of 3.0 micrometers (2,3).

Sterlitech Corporation is excited to introduce the Aquaporin Inside HFFO06 Hollow Fiber Forward Osmosis (FO) Membrane Module. The membrane module fills the need for an intermediate step between bench-scale flat sheet membranes and larger hollow fiber modules. Investment and development in FO membranes and applications can result in both lower capital and operating costs for filtration systems.

FO membranes utilize osmotic pressure which enables a variety of applications, including the treatment of highly saline feed streams. This eliminates the need for extensive pre-treatment and high hydraulic pressures involved in pressure-driven treatment processes, therefore driving down costs.

“The HFFO06 hollow fiber FO module is ideal for customers who have moved past proof-of-concept studies but would like to perform lab-scale testing with hollow fiber membranes before scaling up production,” said YeWee Siew, Global Product Manager for Aquaporin’s FO product line. “Furthermore, it can be applied to a range of biomedical and analytical concentrations at smaller volumes, fitting in nicely below our larger HFFO2 and HFFO14 modules.”

Compared to the larger HFFO2 membrane module’s active area of 2.3 square meters, the HFFO06 provides an active area of 0.6 square meters; this means lower feed and draw solution volumes are required for operation. The smaller hollow fiber module maintains the same inner and outer diameter, housing material, and unique thin-film composite membrane with integrated aquaporin proteins as its larger counterpart.

This module is recommended for development of applications in food and beverage, and treating hard and high salinity water.

About Aquaporin:

Aquaporin A/S is a global water technology company located in Kongens Lyngby, Denmark.

Aquaporin is dedicated to revolutionizing water purification through the use of industrial biotechnological techniques and thinking.

Sterlitech Corporation, a global leader in custom filtration systems, is proud to add flat sheet Forward Osmosis (FO) membranes from Fluid Technology Solutions (FTS H2O) to their offering of filtration products.

The new FO membranes manufactured by FTS H2O are constructed from cellulose triacetate (CTA) material. The highly hydrophilic nature of the CTA FO membranes favors proper wetting of the membranes used in aqueous feed solutions. This means water molecules are easily pulled through the membrane to produce purified water or other feed solutions, even at low pressures.

According to Sepideh Jankhah, Product Manager for Membrane and Process Development at Sterlitech, “The low fouling propensity of this membrane opens up new applications, where pressure-driven membranes currently fail to be efficient.” Additionally, “The CTA FO membranes offer the advantage of being resistant to chlorine.” Compared to traditional thin film composite FO membranes, CTA membranes are easier to use because the membrane filtration system doesn’t need to be devoid of chlorine prior to adding the feed solution. In fact, maintaining chlorine in the water provides an additional bonus of extending membrane life by preventing biofouling.

To enable our customers to explore forward osmosis applications, from seawater desalination and wastewater reclamation to energy generation and food/beverage concentration, Sterlitech is offering these high flux FO membranes in flat sheet format. Taking advantage of the osmotic pressure as the driving force for mass transfer across the membrane, CTA FO membranes can treat extremely challenging wastewaters such as landfill leachate, oily wastewater, and injection well waters without the need for extensive pretreatment compared to pressure driven membrane systems such as reverse osmosis. Additionally, these FO membranes are efficient for treating solutions with high salinity or for concentration of food and beverage products.

Features and benefits of FTS H2O membranes: 

• Low capital and operating expenditure
• Excellent antifouling characteristics
• Energy savings via operation at very low pressure (about 2.5-3.5 bar)
• Ability to treat very high TDS wastewater and concentrate brine

About FTS: 
The FTS management and technical team has specific expertise in water treatment solutions utilizing forward osmosis and complimentary wastewater filtration technologies. Intellectual property development, skills and expertise in commercializing forward osmosis systems, and the capability to achieve Zero Liquid Discharge (ZLD) enable them to meet the most stringent regulatory requirements.

Sterlitech Corporation, a global leader in custom filtration systems, is launching a dual-pressure skid mounted bench-scale membrane filtration system. The new Convertible Skid is specifically designed as a high pressure system for pressure-driven membrane filtration (such as Reverse Osmosis), that can be easily converted to perform either osmotically-driven (such as Forward Osmosis) or temperature-driven (such as Membrane Distillation) processes without the need for any additional parts or equipment. Research priorities evolve over time and lab space is limited; this system offers a unique, flexible solution for academic and industrial scientists with dynamic filtration needs.

According to Sterlitech’s Director of Marketing, Dr. Sepideh Jankhah, “Turnkey systems are a staple in many R&D labs. However, many projects have more than one research focus and the cost of sourcing multiple systems can be significant and challenging to secure.” Dr. Jankhah continues, “This system’s ability to convert between popular membrane filtration technologies can help researchers overcome this pain point."

Features and benefits of the Convertible Skid: 

•     Designed to operate at both high and low pressures
•     Convertible to run osmotically-driven or temperature-driven processes
•     Can be customized for compatibility with harsh or corrosive chemicals
•     Available in both digital and analog options

Each Convertible Skid is highly customizable regarding membrane test cell type and flow configurations. Configured with both high and low-pressure circulation lines, it can be used for a wide variety of applications: processing of water and wastewater, food processing, chemicals, pharmaceuticals, removing organic and heavy metals, and other concentration or separation membrane filtration processes such as reverse osmosis, nanofiltration, ultra and microfiltration, forward osmosis, and membrane distillation.
