Maintaining a golf course has a lot of challenges. Often, one of those challenges is how to clean your golf course care equipment. The equipment you use to clean and maintain your golf course very quickly finds grass clippings, soil, and other debris enmeshed in it, and you need to remove these materials regularly. The type of washing you need to do to clean that equipment, however, creates wastewater — and improper wastewater disposal procedures could see you running afoul of U.S. EPA regulations and receiving unwanted fines.
Spent hops and general brewery wastewater are natural by-products of the beer-making process and must be reused or disposed of accordingly. Some brewers are charged substantial fines for dumping high-solids wastewater into the city sewer system. With Parkson Rotostrainers, over 90% of the Biological Oxygen Demand (BOD) of wastewater can be filtered out, greatly reducing the city sewer charges. Many breweries can even sell much of the spent grain and other captured solids to local farms as livestock feed, thereby profiting on an otherwise ‘waste’ product.
