The OptiPure BWS100 is a complete water treatment system, offering pre-filtration, reverse osmosis, and precision blending capabilities. Its high capacity pre-filtration feature protects the semipermeable membrane, helping with particulate and chlorine reduction, thereby extending the filter’s longevity. Using reverse osmosis (RO), the OptiPure BWS100 is capable of removing more than 97% of the water’s total dissolved solids (TDS).

Due to scale buildup, hard water can cause significant damage to espresso machines, including clogged group heads and even ruined heating elements. Operating at line pressure, the customizable OptiPure BWS100 is capable of producing up to 100+ gallons per day for situations where TDS and hardness mineral reduction is necessary. On top of machine longevity, this is also ideal for coffee preparation. Water quality affects flavor, ultimately changing the extraction process, causing more or less sweetness, bitterness, and acidity. With the BWS100 you have complete control of your water profile.

This is really the BWS100’s hallmark: its ability to blend filtered water with the pure, RO water to produce an Optimized Water. The digital Water Quality Indicator, which can be installed in three different locations, allows you to see the TDS count for both the feed water and the Optimized Water. Thus, with a simple twist of the Blending Valve, the water that comes out of the Optimized Water Outlet is customizable, allowing you to get the right mineral content for your situation.

Included with the filtration system is a pressurized, sealed storage tank (available in 5, 10, or 16 gallon versions). Depending on the amount of equipment at your establishment, a different tank size will fit your situation. As a general guide, we would suggest a 16 gallon tank for use with an espresso machine, batch brewer, and sink; a 10 gallon tank for an espresso machine and batch brewer; and a 5 gallon tank for for either an espresso machine or a batch brewer. We do not recommend feeding an ice machine with this system because they require too much water for the RO process to keep up.

Furthermore, because of its compact and non-electric design, the BWS100 is especially easy to install in tight situations. And with its color-coded hoses, clear directions, and included materials, it is a breeze to install.

Water quality must be assessed prior to installation. For best results, we suggest using a water test kit, though you can simply obtain information from your local water utility. If your water quality does not fit within OptiPure’s defined parameters, additional steps must be taken.
