Aloha,

We are planning a new 9 bed acute unit in our hospital. The big loop will be a MR03 from Ameriwater. We don't have it yet but I imagine it has the standard water pressure and conductivity alarms. We are also going to have an existing MR02 to feed a bicarb mixer and provide some stations for repairs, cleaning etc.

The hospital itself is experiencing internal water supply issues. (The planners are studying how we are going to be hooked up still.) We thought the plan was to tap into the hospital main feed in the parking lot...

Anyway we are concerned enough that we are discussing the need to perhaps monitor the main feed line into the planned unit for flow and pressure, then perhaps other functions of the RO machines. In other words to add the capability to trap info besides the RO alarms, log it and perhpas generate alarms.

I'm wondering if other facilities do somekind of "extended" monitoring and how / what does it do for you? Does anybody find it necessary to monitor other functions such as carbon tank backflush? Any thing else that should be monitored or perhaps should be considered for monitoring?

Thanks, Ron

Hey Ron,
May or may not be helpful, but I placed a 'max indicator' type gauge on the main lines a while back because we were having pressure problems too. I doc the max needle values with my dialy RO/water rm checks. This has helped get the hospital plumbers on board when theres a problem.
similar 'max indicator' guage:

Hi Maui Boy,

Here's what we monitor.
Feed water: pressure, temp. ph, iron (because we do have iron in our city supply pipes)and Chlorine.
Inlet filter: delta pressure,
Blending valve: temperature and pressure,
booster pump: pressure,
delta pressures of Carbon tanks and softeners,
Status of timers of carbons and softeners,(this includes backwash and regeneration times)
brine tank level
Chlorine levels between Carbon 1 and Carbon 2,
Hard water tests after softeners, pressure for R.O. feed water.
R.O. Status (timers etc.)
Pressure of R.O. pumps, filter and membranes,
Flow rates and pressures of Product, recycle and Reject.
Quality or conductivity of incoming pretreated water and product water.
Temp. of pretreateted water entering R.O. and product water temp.
Array recovery and system recovery
valve/leak check.
Pressures of return line
We dont't need Di. tanks where I am located as we have two R.O.'s, but in our associated hospital they do and have lights and audible alarms on the Di's and also a u.v. light with LED and audible alarm follwed by a ultra filter.

Hope this helps.
