Water and Fluid Separation News

In order to provide a safe work environment, better control of vapor wastes needs to be implemented. EZ waste technology has become readily available to improve the containment of volatile liquids and prevent vapors from escaping into laboratory air. Learn about how to prevent the dangers of hazardous waste and the technology behind the closed waste system with an activated carbon filter, such as the EZ waste system. Download EZwaste whitepaper for more detail and additional instruction.

Do you know today, there are over 663 million people, who do not have safe water supply and suffering with health problems from use of dirty water?

Here are some facts about wastewater:

1. Globally, over 80% of the wastewater generated by society flows back into the ecosystem without being treated or reused. (Sato et al, 2013)
2. 1.8 billion people use a source of drinking water contaminated with feces, putting them at risk of contracting cholera, dysentery, typhoid and polio. Unsafe water, poor sanitation and hygiene cause around 842,000 deaths each year. (WHO/UNICEF 2014/WHO 2014)
3. The opportunities from exploiting wastewater as a resource are enormous. Safely managed wastewater is an affordable and sustainable source of water, energy, nutrients and other recoverable materials.

What options do we have to make a difference for

Sterlitech is proud to announce the availability of Aluminum Oxide (Al₂O₃) inorganic microporous membrane filters. These filters are finding use in several specialty applications, ranging from nanomaterials synthesis (where they perform best), graphene synthesis (Buckypaper) and testing, HPLC mobile phase filtering, liposome filtering, environmental monitoring, and more! The Sterlitech alumina membranes are also a suitable alternative to Whatman Anodisc© filters.

These anodized alumina filters are distinguished by swift filtration speed owing to their high pore density, efficient separation, and high purity. The inorganic material is constructed of numerous, narrowly distributed pores in the form of honeycombs yielding a high degree of open space.

Adding to their features, these membranes become almost completely transparent when wet, and display

Sterlitech has developed a new support for the Sepa Cell Assembly to improve ease of handling and facilitate safe operation when assembling the cell or changing membrane coupons and O-rings.

The unique design of the Sepa Cell Assembly Support allows users to safely slide the cell body out of the holder onto a sturdy shelf, minimizing the risk of dropping the body and causing bodily injury. A convenient lower shelf serves as storage for the cell top, spare membranes, or O-rings. The Support can easily be integrated into existing systems configured with the Sepa Cell.

Continuing demand for low energy solutions to separation challenges have fueled Sterlitech’s latest product release: an Air Gap Membrane Distillation Cell. The first commercially available bench-scale tangential flow test cell of its kind, it mimics conditions representative of large-scale systems with minimal use of membrane or product. The AGMD cell offers researchers fast and accurate performance data to easily evaluate the performance of membranes and/or the efficiency of a given process with respect to their application.

How it works: liquid to be treated is circulated in direct contact with the feed side of the membrane in the AGMD cell. A cold liquid solution is circulated in direct contact with a cooling plate on the permeate side of the membrane. Both the feed and the cooling solutions are circulated tangentially while using pumps at low or no hydrostatic pressures. An air gap is created between the permeate side of the membrane and the cooling plate where permeate i

Membrane fouling, defined as the accumulation of particles and organic matter at the surface or in the pores of membranes occurs during membrane filtration. Membrane fouling results in membrane performance loss, i.e. lower rejection values, lower permeate flux and higher pressure drop, which translates into higher operational cost. The extent of fouling depends on the feed quality, operating conditions, membrane characteristics and module design.

Membrane fouling can be divided into three types: hydraulically reversible, chemically reversible and irreversible fouling. Hydraulically reversible fouling can be removed physically (e.g. by introducing turbulence at the proximity of a membrane surface) or through backwashing of membranes. On the other hand, chemically reversible fouling can only be removed by chemical cleaning methods, while irreversible fouling is permanent.

Sterlitech is proud to launch a new product based on the successes of the Autofil bottle-top disposable filter funnel, now in a solvent-resistant version.

The Autofil PP bottle-top filters are a revolutionary new way to purify solvents for analytical applications or purify buffers and extracts. These new devices are the world’s first single-piece polypropylene funnel, designed to withstand harsh solvents that would normally degrade traditional polystyrene bottle-top filter assemblies. All active components are FDA-grade, which makes Autofil PP perfect for extracting compounds used in the food and drug industry. Autofil PP is designed to conveniently fit on top of most laboratory bottles with a GL45 thread, and works seamlessly with the same no-spill cradle system that made the

Our skid mounted membrane filtration systems are specifically designed to bring a new level of ease to bench scale testing of membrane filters and small batch processing. The goal for developing this product was to help our customer do what they do best – research and develop – and minimize time plumbing, wiring and waiting! We are also aiming to ship each skid mounted system within 2 weeks of purchase date.

Already in use in many academic and industry R&D labs for applications such as membrane development, quality assurance, materials research and batch production of micro biologicals, chemicals, pharmaceuticals and others, these skid mounted systems increase productivity and establish consistency in experimental design. Organizations with several different interests can quickly adjust operating parameters to meet an assortment of testing goals.
