Ah i see. And you find that the water needs. Or additional treatment? I'm currently trying to figure out my options and struggling to justify one way or the other. Not to mention not having a dedicated station.Psychoav wrote:Yes, water inlet goes through RO -> BWT, then I spilt it into two outlet, one plumbed to my espresso machine, another to an instant hot/cold water tap
The BWT serve as remineraliser after RO

I'm pretty sure that Psychoav intended to say 'Bestmin' and not 'Bestmax' here. The former is a remineralizer and the latter is a decarbonizing filter.Psychoav wrote:The BWT serve as remineraliser after RO

Water are on the acidic side from where I live, so I have added BWT to remineralised. RO was to making sure the purity of the water. I bought a set of water testing kit to test my water and make adjustments accordinglyOK31 wrote:Ah i see. And you find that the water needs. Or additional treatment?

It's was Bestmax Premum, it says it will minieralises filtrate with magnesium, I also got that from a BWT local official distributor. Unless I have misinterpreted it, then I would need to correct it.homeburrero wrote:I'm pretty sure that Psychoav intended to say 'Bestmin' and not 'Bestmax' here.

The Bestmax Premium has a patented weak acid cation (WAC) ion exchange resin which does replace some calcium ions with magnesium ions, but aside from that I don't think you can expect much if any remineralization. Like other WAC resin decarbonizing filters it should tend to decrease both hardness and alkalinity. I suspect that it also has some buffering capacity that might help raise the pH of acidic water.

P.S.
Sorry for straying a little off the topic here. Followups about this water issue would be best posted over in the water forum. It would be interesting to learn if you have actually detected an increase in hardness using that fancy Hanna hardness photometer on RO after running it through a BWT Bestmax Premium.

I have run the test once after the installation and after using for a while with the lowest settings (3) of the BWT, all parameters were within acceptable brewing range except for ph, calculation of Barista Hustle LSI calculator saying my waters was corrosive to machine. So I turned up for another level, using it until now without doing another test. Subjective taste wise, lowest level already pretty good compared to without water systems, another level up taste still good for manual brewing but seems too salty for espresso, which I need to extend the brewing ratio to compensate the saltiness. You're right maybe I have missed interpreted the function of the filter, I should do further testing and consider changing to the correct filterhomeburrero wrote:The Bestmax Premium has a patented weak acid cation (WAC) ion exchange resin which does replace some calcium ions with magnesium ions, but aside from that I don't think you can expect much if any remineralization.

Water testing equipment worth the investment, more economical friendly to share with couple of friends, cause you only need to do it once a long while. Way cheaper than a coffee TDS meterOK31 wrote:wow that's an elaborate tester. thanks for the info.

Can I use this bestmin premium filter with bottled water from the store in a closed tank system ( Espresso Cart - Goodbye Plumbed In ). I'm not fond of reverse osmios and my machine's location doesn't have any line to connect it.homeburrero wrote:The Bestmax Premium has a patented weak acid cation (WAC) ion exchange resin which does replace some calcium ions with magnesium ions, but aside from that I don't think you can expect much if any remineralization.

I think you could use it but it may not deliver what you want. The Bestmin, like most remin filters, is designed to work with RO water that generally has a low pH that helps dissolve the mineral in the filter. If you have a carboy system and want consistent and reliable mineralization I think you are better off with a recipe approach - adding mineral salts in the amounts you want to the purified or bottled water in the container.Ad-85 wrote:Can I use this bestmin premium filter with bottled water from the store in a closed tank system ( Espresso Cart - Goodbye Plumbed In ).
