Hello all, it’s always a good idea to soften the water at the point of entry to protect everything thereafter from the build up of scale. So for the Osmio Zero it’s solenoid valve will scale up just the same as the one on a dmonestic boiler. However the problem is exacerbated with the Osmio Zero because of its way of recirculating the concentrate.
So what happens in practice is everyone who is in a soft water area or who is in a hard area but has a working salt softener, we have never any problems with the machine after sales.
The only problems we have in where the customer never descales the machine. To descale it you need the empty filters in the sanitisation kit, and rather than use Milton tablets you would use citric acid.
The Osmio Zero and all the other RO systems remove sodium carbonate to less than delectable levels on mg/l, so pretty much full proof for removing the approximate 150mg/l added on average by a softener. The UK regs for sodium are 200 mg/l.
We use a ro system and an inline system for a commercial coffee machine at Pureplanet Cafe, the inline system has a 0.2 micron ceramic filter and a DEalk resin filter. All in all it will keep the machine boilers etc from build up of scale which is really the first thing that will make it go wrong.
I’m in the market for a used single group lever machine and a couple of commercial grinders if anyone knows of any for sale?
Also in other news we sourced biodynamic green beans from Henrique Sloper at Camocim in Brazil and are roasting and packaging and now supplying 3 other cafes and shops. Check out Pureplanet Natural Coffee if you haven’t tried it yet, I’m sure you will like it.
BBC food producer of the year finalist, Tablehurst Farm just recently switched their cafe to Pureplanet Biodynamic Coffee, they said it was so much better than the organic coffee they used and it is. Organic can mean so many things. It can be GMO for example. But biodynamic produce is as pure as anything you would pick wild and it really shows in the feel of the coffee.
