Membranes to operate at optimal level for longer
Complete Filtration Resources’ baseline designs incorporate stage isolation valves and a proprietary programming sequence to provide efficient product recovery during flushing and a startup that allows the membranes to flux at an optimal rate throughout the production run. This baseline, along with the utilization of flush valves at every stage, provides reduced CIP times and less water, thermal and chemical consumption. As an added benefit membranes operate at an optimal level for a longer period, according to the company.

PSI-Pleat, pleated filter cartridge
Powder-Solutions Inc.’s PSI-Pleat filter cartridge has wide-pleat spacing and provides significantly more filtration surface area than a fabric filter, according to the company. The filter cartridge has greater than 99.99% air filtration efficiency, which equates to cleaner air and more time between filter replacements. They can be installed quickly and are constructed of 100% polyester spunbond media. Optional surface treatments are also available.

Outer wrap for large-diameter sanitary spiral wound elements
To meet rigorous sanitary requirements for large-diameter spiral wound elements in dairy applications, Parker’s Domnick Hunter process filtration division developed a sturdy mesh ST-QT outer wrap. According to the company, this design offers improved strength and open flow channels, allowing access for cleaning and sanitizing chemicals. Its durability prevents element expansion and damaging effects of channeling, all under sanitary construction. The outer wrap also allows for flexibility to fit a range of housing diameters and variances while eliminating excess net trimming.

Improved membrane filtration process technology
GEA Filtration’s new patent- pending process technology substantially improves the operating economics in the production of whey protein isolates, micellar casein concentrates, and serum protein concentrates or isolates, according to the company. The new technology improves electrical efficiency during processing nearly two-fold while maintaining exceptionally high retention and transmission rates of target molecules. The process technique is based on low-cost and readily available, spiral-wound membrane platform.

NIR technology for membrane filtration systems
Prospect Analytical Technology Inc. designs, builds, and markets in-line near-infrared (NIR) analyzers capable of detecting individual dairy constituents such as protein, fat and moisture in a retentate stream from ultrafiltration membrane systems. With the ability to relay data to the membrane control system, dairy processors are able to reduce the standard deviation of their finished product by an average of 50% or more. The single and double process stream in-line NIR analyzers give measurably improved process control, resulting in lower costs and higher productivity, according to the company.

Membrane module updated with 4% more membrane area
Microdyn-Nadir’s Bio-Cel BC416 module is now equipped with 4% more membrane area. The increase in membrane area allows for an optimization of the crossflow and another increase of the packing density, the company states. The membrane bio reactor is used for wastewater treatment which separates within the ultrafiltration spectrum. It produces high capacities of quality effluent at consistent flows. The solids-free effluent is suitable for recycling applications such as irrigation or feeds for process water. Bio-Cel’s configuration is based on flat sheet technology, with crossflow-inhibiting clogging and reducing downtime. The module’s open top and bottom channels prevent the deposition of sludge and fiber accumulation during the continuous crossflow operating process.

De-wheying unit for cheese processing
Qualtech added a de-wheying unit to its Curd Maximizer line, its most advanced fines saver, part of its lineup of cheese processing solutions. The system has no mechanical or moving parts, no wear components, and no consumables, combined with improved cleanability, minimized maintenance, ease of inspection and integration to existing clean-in-place systems. The new design keeps the principle of the original technology, but instead of handling fines the unit is now focused on curd. Whey and curds are cascaded over a screen where the cheese curds and whey are separated.
