Brewery Filtration Systems

When brewing Beer the Brewery Filtration Systems is a must to understand.  Sure we use Hops, Barley, yeast and Malt to make a good beer but what is the main ingredient in Beer?  Water, so why wouldn’t you put your best effort in making a good water product? Water is the main component to the mix and it can certainly vary from all over.  This makes your beer taste differently than the next. Using the best-purified water will eliminate one possible issue should something arise in the Brewery. We don’t brew beer but we do think logically.  Why wouldn’t you want the imperfections that can change the way the beer brews out of the water? You want to sell the masses than you need consistency and that comes in the form of water as well as the other ingredients.

Brewing beer is a talent that should be prized and prided on the best water consistently available.  We offer water purification systems that can deliver just that. We work with you to craft a system that is all your own.  Sometimes we are asked to put back certain Ions as it helps with the process and we can do that as well.

Wastewater for Breweries

With water being the top ingredient for Breweries, this means that you need to think about the drainage of the wastewater. Sending all that wastewater directly down the drain without precautions is going to get costly and most likely you a visit from the water department.  And, we are not talking a fun visit. The wastewater for breweries contains a lot of sugars and alcohol, and solids. These things are not friends of a wastewater management system. The alcohol and sugar make for a high acid. This can be very bad for wastewater pipes and so the agency will most likely ask you to treat your water before you send it to the sewer.  And, we can help you with this.

This is another concern for a water treatment option in a Brewery, the wastewater.  Nobody really thinks about the wastewater being an issue. But, we don’t want to corrode the city sewer pipes, just image that costly bill.  To keep the solids from entering the water, floor drains are the way to go, have a grid that will catch the solid waste before it enters the water purification system.  This will then be thrown out with the trash and not flushed down with the water.

Solids in water cause a problem in pipes and at the city level.  This doesn’t just magically disappear but has to be treated before the water can be flushed out of the system.  Solids are a pretty easy fix as they can be removed manually with screens and then employees can keep the screens clean.  This will help with water bills.

Let us get your brewery in tip-top condition for your brewing needs.  We want you to see only success in your business as we too love a good brew.

California Brewers: Why you need a Filtration System for your Micro Brews

California Breweries make some of the greatest and Hoppiest brews in the US. We are dedicated to serving the Brewers of California to help them make the best quality product that they can. To do this we build the exact system that will meet your needs and keep the environment clean with the smallest footprint possible.

Environmentally Friendly Brewery Filtration Processes

Breweries in general use a lot of product to manufacture the batches that they bottle, ship and tap. This product inevitably turns into waste, and a lot of it. Water waste is one of the these byproducts. The water waste that is created from the whole brewing process.

 

A few of the main concerns are the CIP water, sugar from the barley and the yeast that creates alcohol. You can see that these are a few things that shouldn’t be in our water and cost a lot to clean. With our system, waste water discharge is kept at a minimum and well below the guidelines set by the Clean Water Act of 1972.

Generally speaking, brewery wastewater has a few common characteristics:

  • High in sugar
  • High in alcohol
  • Potentially high in solids
  • High temperature
  • Low pH

Together, the sugar and the alcohol create high BOD: biochemical oxygen demand. I won’t bore you with a lot of detail about what BOD is, but think of it as food, or nutrients. These nutrients need to be consumed by bacteria in a wastewater treatment plant before discharge to your local body of water. High BOD wastewater creates more work in the wastewater treatment plant. The primary way this extra work shows up is in the electric bill. Wastewater is treated aerobically in most municipal treatment plants. Large blowers are used to aerate the water, providing oxygen to the bacteria to consume all of those nutrients. More nutrients = more aeration = more money.

Solids are also a problem at a wastewater plant, they don’t magically disappear.  Solids usually wind up as sludge in a wastewater plant, which need to be disposed of.  Sometimes they’re fed to an anaerobic digester then dried and sold, or their landfilled, or dried in the sun.  Solids are a real problem at a wastewater treatment plant.

Brewery wastewater can also be corrosive, both to your equipment and to the City owned pipes and pumps downstream. There are 2 issues going on here, high or low pH wastewater as well as hydrogen sulfide gas. Brewery wastewater is naturally acidic, usually tending to stabilize at pH 4.5 or so. However the wastewater can also be high in pH during CIP cycles in the brewery. The pH will lower as the water sits due to wild yeast and bacterial metabolic activity. Many breweries have discharge limits imposed on them by their municipality in regards to pH. Some will be generous with limits between pH 5.0 to 11.0. Others will be tight, for example 6.0 to 8.0. You might be lucky and have no limits. These limits vary widely state by state and even town by town.  Some cities have no enforced pH limits at all.

The other corrosion issue is H2S, hydrogen sulfide gas. In the presence of water vapor the H2S creates sulfuric acid. In time this eats away at concrete, mainly above the water line. The sulfuric acid will also eat away at any mild steel (rebar) it can get to. For this reason I favor plastics and stainless steel for piping and pump materials. For underground tanks and vaults, lined concrete really is really the only way to go. Plastic tanks can be designed for underground use (plastic septic tanks), but they usually have high temperature limits of 120F or so. Your wastewater will approach 200F at certain times. It will. It’ll always be an accident or mistake, but it will happen. A collapsed tank would be very inconvenient. Urethane is a good liner material in the concrete vault.

Solids in the wastewater can be an issue. Solids are fairly easy to address because they can be removed mechanically. A good starting place in screens in the floor drains- with employees trained to dump the screenings in the trash (not back down the drain, duh). Another good starting place is to not put the solids in the drain in the first place. Think lauter tun rinsings, hop back rinsings, trub… More on that subject later.

What are some solutions to these problems? We have high BOD, pH, solids, and corrosion problems. Remember the opening lines to this diatribe, ‘What’s the big deal with brewery wastewater?’
