IntroductionPurpose of our project Reverse Osmosis Unit ConstructionCurrent Method UsedConcept EvaluationParts of the Membrane Removal Tool

Operation of toolConclusions

Purpose of ProjectRemove membranes from reverse osmosis

unitMaintain removal time the same or betterReduce the number of people neededRestricted on fluids we can useBuild an ergonomic and safe tool for the

technicians to use

Concept EvaluationPro’s

Pulling Device Pushing DeviceBoth technicians on

same end of unitNo external fluids

necessaryMore control on removal

Less technician force needed to push

One piece tool

Concept EvaluationCon’s

Pulling Device Pushing DeviceNeed to counter weight

the toolWire rope must be stiff

enough to feed through the membranes

Long length of wire rope

Rod must be longLimited to glycerin to

use for hydraulic fluidTechnicians on both ends

of pressure vesselLess control on

membrane removal

Removal Tool Operation

ConclusionCurrent removal practice was unsafe and

unsound ergonomic practicesUnique tool

Safer Ergonomically sound Only two people to perform job of four Maintain same removal time Can fit multiple reverse osmosis units Does not damage membranes on removal Withstands wet harsh environments
