Introduction to Beer Production Process

Barley → Soaking → Germination → Crushing → Saccharification → Filtration → Cooling → Fermentation → Filtration → Filling → Sterilization → Finished Beer

Wastewater mainly contains sugars, alcohols, and organic compounds with high concentrations. During the soaking process of barley, pentose, sucrose, glucose, and cellulose in the outer skin are dissolved. Protein proteins, tannins, bitter substances, etc., with soluble substances ranging from 0.5% to 1.5%, and the wastewater is brown in color. It also contains various amino acids, alcohols, vitamins, hops, cellulose, and maltose.

The amount of beer wastewater depends on the production scale, and generally about 12-20m3 of wastewater is discharged from brewing 1 ton of beer.

Beer wastewater mainly comes from malt workshop (malt soaking wastewater), saccharification workshop (saccharification, filtration and washing wastewater), fermentation workshop (fermentation tank washing, filtration and washing wastewater), filling workshop (bottle washing, sterilization wastewater and beer from bottle crushing), and cooling wastewater for production.

Characteristics of Beer Wastewater

Wheat making and brewing are two parts; Both of them produce cooling water, which accounts for about 65% of the total output of the brewery. The water quality is good and can be recycled for the malt soaking process. The sources and concentrations of high pollution wastewater in the beer industry.

In brewery wastewater, high concentration organic wastewater has weak acidity and a pH value of 5-6.5; CODcr：1000—2500mg/L; BOD5：500—1500mg/L; SS：220—440mg/L; B/C ratio>0.45; Beer wastewater has high biodegradability.

The wastewater from the beer industry mainly contains sugars, alcohols, and organic compounds with high concentrations.

Brewery wastewater treatment process

Dongguan Gaoda Environmental Protection Technology has developed several solutions for the wastewater treatment project of a brewery: Firstly, SBR is the main component for hydrolysis acidification, with fillers installed in the hydrolysis acidification tank, a hydraulic retention time of about 4 hours, a COD removal rate of 30% -40%, and a pH value of 2.8. The reaction time in the SBR reaction tank is about 6 hours, the water temperature is 20-25 ℃, the sludge concentration is about 4000mg/L, the effluent quality meets the first-class discharge standard, the COD removal rate is 92%, and the BOD removal rate is 98%.

1： The characteristics of SBR treatment process are the integration of biodegradation and final sedimentation drainage functions. Compared with traditional continuous activated sludge, it can eliminate sedimentation tanks and sludge return facilities, and has stable operation, high purification efficiency, shock load resistance, avoidance of sludge expansion, and easy operation and treatment.

2： UASB → Contact Oxidation

The UASB reactor integrates biological reactions and sedimentation, with a compact structure. Wastewater enters from the bottom of the reactor through a water distribution system, passes through a three-phase separator of gas, solid, and liquid in the reaction zone, and enters the sedimentation zone. After the separation of gas, solid, and liquid, biogas is collected in the gas chamber and then flows through the biogas pipe to the biogas holder. There is no stirring equipment in the UASB, and the rising water flow and biogas generated airflow are sufficient to meet the stirring needs. The UASB reactor has a simple structure and is easy to operate; For soluble organic wastewater from beer production, the hydraulic surface load in the sedimentation zone is 3m3/(m2); The COD removal rate is around 75%, and the pH value is between 6.8-7.2.

Determine to adopt the process of "pretreatment+regulating tank+anaerobic+aerobic". This process is based on the principles of economic rationality, stable and reliable operation, and high efficiency, with low investment, minimal land occupation, and low operating and management costs.

Treatment process: "Anaerobic UASB+Aerobic Membrane Bioreactor" effluent quality: "Water Quality for Landscape Environment of Urban Wastewater Reuse" (GB/T18921-2002), with CODcr ≤ 50mg/L. The local standard for water pollutant discharge limits in Guangdong Province is DB44/26-2001 Level 2 standard.
