orenCOr Design Application Types Applications can typically be classified into one of seven application types,each characterized by waste streams and usage characteristics. Table 1 lists each application type,examples,the criteria used to establish each type,and associated design notes. It is important to note that the flow and constituent concentration ranges associated with each application type represent Orenco's observations from similarly classified applications. However,they do not represent actual flows and constituent concentrations of the applications at hand.The engineer is responsible for ensuring that wastewater in each project is properly characterized and,whenever possible,waste streams should be sampled and actual values used in the design.
