System Components
The VSEP filtration system consists of 5 major components: the frame, drive system, plumbing, filter pack and control system. Download the complete system specifications
Frame A 2" tubular steel construction is used with an epoxy powder coat to assure resistance to chemicals and weather. Drive system This patented system includes a 10-20 horse power motor which drives an eccentric weight and seismic mass, which in turn translates the energy through the torsion spring into the filter pack. Plumbing Teflon (FEP), polypropylene and stainless steel are used throughout to assure maximum compatibility with most solvents, caustics and acids. VSEP filter packs employ a filament-wound outer housing, stainless steel plates, polypropylene or kynar permeate carriers and epoxy resins. New Logic offers in its filter packs virtually every type of membrane made today including:acrylic; nylon; polyacrylonitrial (PAN); polypropylene; polysulfone; polycarbonate; PVDF (Kynar); stainless steel; Teflon; thin-film composites; Tyvek and others. Most of these membranes have a wide range of pore sizes to choose from ensuring the optimum separation for any application. At one extreme, reverse osmosis membranes reject most dissolved compounds, including salts, while allowing water molecules to pass. Nanofiltration membranes are used to reject molecules of sizes ranging from 1 to 100 M.W. (these are sometimes referred to as water softening membranes) while Ultrafiltration membranes can reject molecules of sizes ranging from 100 to 1 million M.W.). Microfilters with pore sizes ranging from 0.1 micron to 10 microns are also available as are woven screens with 1 micron pore size to standard mesh sizes used for coarse separations. The standard modular size of a VSEP System is 100 to 1,400 square feet composed of discs with a 19 inch (48 cm) active diameter. Each disc element is manufactured and quality-assured by New Logic.
Control System VSEP systems are normally supplied complete with Allen Bradley SLC 500 series Programmable Logic Controllers. All components are fully contained in a NEMA 4 rated enclosure. Various levels of control sophistication are available depending on the complexity of the application. For polishing or low solids applications, simple controls having minimal outputs and inputs are provided. For high solids applications, controls with more features are used to ensure trouble-free operation. The VSEP controller typically sets solids levels by actuating the exit valve based on operating parameters such as motor current or temperature. Other control options available include automatic clean-in-place, automatic flush, automatic shut down, full alarm features with digital diagnostic displays, remote diagnostics and monitoring, and many others. New Logic engineers have spent years perfecting VSEP controls to maximize reliability and to minimize operator intervention
