Pall Corporation Package Water System (PWS) & Next Generation Processing Filters (NGPF)

 
 

Package Water Initiative

Objective: Clean water is a benefit we may under-appreciate. Water is essential to life, and in many cases essential to industries. Pall Corporation provided numbers solutions to a variety of industries. “Clean” water could mean different things to different business, the water filtered for wine & beer production, may be different than those of ceramic counter polishers, or a municipality providing drinking water for an entire community.

Package water outline: used to illustrate size/scale of device as well as features/functions and its scalability to meet client requirements and conditions..


 

Current HMI screens: Images show examples of initial starting point of project, and ENVIRONMENTAL conditions in which these devices are OPERATED. These images were taken from onsite tours to provide context of end user ENVIRONMENTS, and interaction methods.

Site Visit / Operator Interviews documentation of environmental conditions


Work and Task Flows of Operator and Site Advisor | Calls to Action / Decision Tree - Understanding basic tasks and goals of both the end user, as well as the managed personnel, enables the prioritization of information to be displayed. High turnover rates of operators, dictated simple controls, and ease of learning become the underlying theme throughout the project.

 

Setting goals for VARYING success criteria enable the tracking of progress and evaluation of multiple aspects. The improvement in multiple areas provided program manager the CONFIDENCE to incorporate the updates and use as a sales tool.


 

Proposed HMI screen with sampled display and interaction patterns Final HMI screen changed from 17” mouse driven to 8” touch screen. These late changes within the product development LIFECYCLE caused a large amount of churn and TURMOIL.
