Evening gents,
Hope you can help with this as my business partner and our usual window cleaning contacts are at our wits end with this. We decided to get into the window cleaning business about 6 weeks ago and purchased a load of equipment from a friend — this included a purification system (pre filter, 2 RO's and 1 DI) along with some brushes, poles and tanks etc.
Pretty much since we got the equipment we've been getting a TDS reading of around 30 or so coming out of the RO, obviously this takes it's toll on the resin filter and we've already had to replace the resin once as the TDS readings were getting too high. We've done the following and still we're getting readings of 25-30 coming out of the RO:
- Had Thames Water come up to give us a dedicated line to improve psi/flow
- Purchased a pump to increase PSI going into the pre-filter (we generally get about 120psi now)
- Replaced the membranes in the RO and replaced the pre-filter (we did this today as a last resort thinking it would solve the issue)
Yet still, we're getting readings of approx. 30 coming out of the RO and now it's started to creep up to 5-6 coming out of the DI so obviously the resin needs to be replaced again.
Does anyone know what the issue could be? As I said we're kind of at our wits end so any help would be much appreicated!
Cheers,
Ryan
