REVERSE OSMOSIS PRE TREATMENT IS CRITICAL

Let’s talk about how critical proper pre treatment is for any reverse osmosis system large or small and whether the raw water source is municipal or a private well. As we discussed in earlier blogs there are several materials or contaminants in the water that can foul the taste of your brew and it is some of the same things that can foul your RO system.

Before any water treatment equipment is sized and designed you should consult your latest water quality report. If you are on a municipal water supply you can simply Google the current water analysis from your local water company and find out exactly what is in your water. If you are on a private well water supply you should have the water supply tested by a local reputable lab. We here at http://www.microbrewwwatersystems.com will read and consult you on any report at no charge.

the most common fouling and scaling materials to RO are turbidity, iron, manganese, calcium, magnesium, organics, chlorine, and Chloramines. You can find all of these pesky things in most water supplies some higher and some lower. If you have have high turbidity which is generally found in in untreated well water you will require a http://www.microbrewwatersystems.com NXT sand Filter. Common levels of iron and manganese can be treated with a http://www.microbrewwatersystems.com BrewSoft system. The most common is water hardness resulting from calcium and magnesium and trust me you have it….a good antiscalent system or BrewSoft will eliminate if not slow down those problems. And for some of the worst enemies, chlorine and CHLORAMINES. Remember that we talked about standard granulated carbon and how it will not work with chlorimines but will work with chlorine and organics. This will require our http://www.microbrewwatersystems.com special carbon blend that takes care of all of those issues.

Sizing is also very critical in all pre treatment  systems for proper flow rates, contact times, flow, and pressure.

Please Brewers ….do your homework when it comes to the proper pre treatment design for your RO investment…if not it will come back to bite you in a very expensive way.

Of course we here at http://www.microbrewwatersystems.com can do your home work for you..

see ya next time

Cheers

CHLORINE AND CHLORAMINE PROBLEMS

Most municipal water supplies are treated with chlorine and now more than ever Chloramine which becomes a big problem for brewing bringing bad things to the flavor of your beer.

Chlorine has been used for more than 100 years for disinfection of drinking water to protect  public health from diseases which are caused by bacteria, viruses, and others orgnisms. Chlorine was fairly easy to remove within the brewing process you could simply boil it off, let the water stand for a few hours, or use a basic carbon filter.

Now more than ever Chloramine is being added to our municipal water supplies and its primary purpose is to maintain disinfection for a much longer period of time in the distribution system. This is a completely different problem that is not so easy to deal with. Chloramines are produced by combining chlorine and ammonia. While highly toxic at high levels, neither pose health concerns to us at the level used for drinking water but do cause problems for Brewers large and small.

one of the problems is that yeast eat Chloramine and chlorine and produce ‘chlorophenols’. These phenols have extremely low taste thresholds; you can taste them even if they exist in only a few parts per billion. Your beer will have a difficult time on defining it’s true flavor and will have an almost chemical or medicinal after taste.

SOLUTION

The best way of treating both of these problems is by using a high quality Catalytic Activated Carbon System such as our http://www.microbrewwater.com SC System. Standard GAC or activated carbon will not remove chloramines. Our product has a high capacity and a high flow rate design to maximize its efficiency and give you the flavor you want without the after tastes and brewing problems.

Next time we will discuss the many benefits of using REVERSE OSMOSIS…
