Brewery Waste WaterSolutions for the Problem Presented at the 2010 Water and Waster Water Conference, Madison, WI By Fred M Scheer VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem • What will we discuss: • Sources of Brewery Waste • Brewery Waste; impact on BOD & SS; pH etc • BOD; where does it come from; high and low numbers; effect on Environment • Definition of SOLIDS • Brewery By-products VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem Impact on waste water Definition of solids Sources of waste water Impact on Waste water EFFLUENT Responsible Brewing Operation EFFLUENT Brewery By-products Sources of waste water Publications at www.mbaa.com VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem • Sources of Brewery Waste Milling – Dust • Mash tun – Wet spent grain; last running's • Wort kettle; hot trub; spent hops • Whirlpool; trub; spent hops • Fermentation; Yeast, beer • Beer Storage: Yeast; beer • Filtration: Spent DE; beer • Packaging, Utility Material: Ammonia, Glycol, lubricating oils etc VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem • Brewery Waste; impact on BOD & SS; pH etc • * SS = Suspended Solids • (beer, extract, sugars, have no SS, but they have dissolved solids • Depends on aging time and filtration conditions. The BOD can be high if pumping and filtration create a lot of yeast cells in the filter bed (DE and Yeast) VOITH MERI ENVIRONMENTAL SOLUTION
Sources of Effluent loads VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem • Brewery Waste; impact on BOD & SS; pH etc • Brewery cleaning solutions: • If Brewery cleaning solutions, such as acids or caustics, are released rapidly into a waste water treatment plant drastic pH fluctuations within the effluent will result. That pH fluctuation can cause operational problems … • SOLUTION: • Slowly meter the cleaning solutions into municipal waste plant; adjusting for high – or low pH VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem • BOD; where does it come from; high and low In the table above we see how much Oxygen is utilized in the “BIOCHEMICAL OXIDATION” calculated in mg of oxygen per liter. The high BOD is a result of organic substances. VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem • Definition of SOLIDS • Solids can be classified into five different types: • 1. Suspended Solids (SS) • 2. Suspended Volatile • 3. Dissolved • 4. Total • 5. Total Volatile VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem • Definition of SOLIDS • Solids can be classified into five different types: • *1. Suspended Solids (SS) • SS are solids that are non- filterable with glass fiber filters, equivalent and not volatized at 103*C • Very small particles remaining dispersed in a liquid due to turbulent mixing that can create turbid or cloudy conditions. Measured in milligrams per liter (mg/L). VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem • Definition of SOLIDS • Solids can be classified into five different types: • 2. Suspended volatile solids are that portion of suspended solids that are volatized at 550*C VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem • Definition of SOLIDS • Solids can be classified into five different types: • 3. Dissolved solids are those solids that are in solution and therefore filterable VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem • Definition of SOLIDS • Solids can be classified into five different types: • 4. Total solids are all of the solids present whether suspended or dissolved VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem • Definition of SOLIDS • Solids can be classified into five different types: • 5. Total volatile solids are the portion of the total solids that are volatilized at 550*C VOITH MERI ENVIRONMENTAL SOLUTION
Brewery Waste WaterSolutions for the Problem • Brewery By-Products • *Spent Grain • *Spent Yeast • *Trub • *Spent DE • *Caustic Solutions • * Heavy Metal VOITH MERI ENVIRONMENTAL SOLUTION
