Sludge dewatering machine is widely used in breweries. It can improve water quality, reduce energy and material consumption, reduce pollutant emissions, and achieve the goal of energy conservation and emission reduction. Multi disc screw press has simple structure, convenient operation, low maintenance cost, large processing capacity, energy saving and environmental protection, and is suitable for the needs of different fields. Sludge dewatering equipment has significant advantages and is suitable for breweries of all sizes. Apoaqua can customize and manufacture complete equipment for customers around the world.
Advantages of Sludge Dewatering Machine in Treating Brewery Wastewater
Beer is a beverage, which has high requirements for environmental hygiene. The front-end treatment can be done with underground equipment or civil engineering pools. The sludge dewatering section must be ground equipment. Sludge dewatering equipment has its own spray cleaning device, which will not damage the environment again.
Energy consumption cost issue. The energy consumption of sludge dewatering machine is 0.55Kw--5.9Kw, which is low. It is made of 304 stainless steel and does not require filter cloth replacement, reducing operating costs.
The sludge dewatering machine is small in size and occupies a small area under the same processing capacity. It does not require full-time personnel to supervise it during continuous operation, which is more friendly to small wineries.
Characteristics of brewery wastewater
Sources of brewery wastewater:
l Malt workshop (malt soaking wastewater).
l Saccharification workshop (saccharification, filtration and washing wastewater).
l Fermentation workshop (fermentation tank washing, filtering washing wastewater).
l Filling workshop (bottle washing, sterilization wastewater and beer flowing out of broken bottles).
l Cooling wastewater for production, etc.
Difficulties in brewery wastewater treatment:
The amount of water used in the beer production process is very large. Especially in the brewing and filling processes, a large amount of wastewater is generated due to the large amount of fresh water used. Due to the large number of beer production processes, the water consumption and water quality per ton of beer in different breweries vary greatly. Domestically, the total water consumption per ton of beer from saccharification to canning is 10-20 tons.
Harm of brewery wastewater to the environment:
According to national regulations, beer wastewater cannot directly enter rivers, lakes and seas. If the brewery wastewater is not treated, the BOD value of 100 tons of beer produced each year is equivalent to the BOD value of 14,000 people's domestic sewage. The suspended solids SS value is equivalent to the SS of 8,000 people's domestic sewage. The degree of pollution is quite serious, so the beer wastewater must be treated to a certain extent.
