Selection Process Introduction

Identifying customer needs

Schematic

In order to meet filtration
specifications, physical and S E L E C T
chemical conditions of the Selection Process
process have to be considered.
It is therefore essential that a
methodical process for identifying
the customer’s needs is followed. START with the COMPETITIVE TECHNICAL Applications
The SELECT process builds on end in mind EFFICIENCY LIFE ECONOMY ADVANTAGE SUPPORT Ultra-Pure
principles used to select the Water (UPW)
optimized filtration solution for the
high-purity chemical manufacturer.
High-Purity
• What is the customer • What type of filter? • Life to blockage • Existing housings • Differentiation • Ongoing Support Solvents Isopropyl
trying to achieve? – Coarse – bag, etc – Life to loading – Identify housing through support – Contract testing Alcohol (IPA)
– Ultra-purewater – Depth/pleated – Identify volume/through – Determine correct programs – Troubleshooting
– Pre-filtration to trap – Pleated membrane put (batch size) filter code – Operator training – Technical audits High-Purity
and final filters – Retention/efficiency – Flow rates – Length/width – Process audits – Operator training Acids & Bases
– Filtration of raw – Grade of filter media – Particle concentration – Filter changeout – Validations
materials or additives (micron) – Correlation of pressure • New housings – Returned filter analysis – Product trials Hydrouoric Acid
– Vapor filtration – Single pass drop to particle spec – Chemical compatibility – Contract testing – Scale-up
– Distillation of – Multi pass – Operating pressure/ High-Purity
concentrated chemical – Support material • Filter compatibility temp • Parker cross- • TSG Support Acids & Bases
– Venting of tanks – Media – Chemical/solvent type – Fittings/vents divisional solutions – Experienced and highly
– Stage pre-filtration – Solids loading and concentration – Materials of construction qualified scientists Sulfuric Acid
– Final package filtration – Operating temperature – Size–flow rate • Alternative – Fully equipped labs
– Viscosity technologies High-Purity
• What are the target • Operational efficiency – Custom engineered • Regional Support
contaminants? – Low downtime solutions Acids & Bases
Hydrogen Peroxide
– Hard particles – Low hold-up volume • Divisional Support
– Gels – Disposable costs
– Fibers
– Moisture • Product and process
– Metal ions safety Services
– Minimize operator
