TM3: Recycled Wastewater System Components and Costs Recycling Treated Municipal Wastewater for Industrial Water Use Process water quality requirements can dictate a range of treatment requirements. For the industry categories represented in Table 10, the base supply is sufficient for sand and gravel washing. It could also be an acceptable source for use in other processes that are not concerned with hardness and dissolved salts, as in the Non-Metals and Other industry categories. Process water is not listed for agricultural processing because most of these products are for human consumption and similar to some state’s practices, is expected to be lower on the list of practices for approval. If reclaimed water is used in food products, Tertiary 4 water with final UV would likely be required. Reclaimed water with tertiary treatment is expected to be required for water supplies used by the pulp and paper, mining, petroleum, chemical, ethanol, and metals industries. It is possible that a base supply could be used in the iron mining industry, but the separation processes for iron ore include use of chemicals and excessive dissolved constituents may cause problems. Likewise, some processes in pulp and paper production could use a base reclaimed water supply, but typically dissolved constituents are not desired because of potential effects on attributes such as color quality. These industries, along with petroleum, chemical, ethanol, and metals industries typically require process water with low dissolved solids and the absence of trace constituents. Tertiary processes such as reverse osmosis followed by GAC, ion exchange or other technologies may be required. 4.0 Storage and Transmission 4.1 Overview An integral part of the planning, operation, and maintenance of water reuse systems is for the transmission of the reclaimed water to the customer. Transmission costs, both capital and O&M, are often the largest cost component of projects for centralized systems. Transmission systems include on-site storage, pump station(s), piping, offsite storage, diversion structures to off-site storage ponds, service connections, and metering. Most states with regulations and guidelines include standards for the design, installation, operation, and maintenance of the transmission systems. There are very specific guidelines for prevention of cross-connections to other systems, including use of backflow preventions devices and other plumbing features. 4.2 Storage This study assumes only storage for diurnal, daily or weekly industrial demand patterns that the WWTP cannot meet with their continuous supply. The conceptual water reuse system presented in Figure 1 provides for storage facilities on the WWTP to meet a range of storage volumes. The base water reuse system assumes that no storage is required. This assumption is valid for a larger WWTP serving smaller industrial demands. Storage requirements for industrial applications can vary widely. Some industries may have adequate storage to meet peak hour requirements, but most would not have storage to handle significant volumes. The need for storage is most likely with Craddock Consulting Engineers 27 In Association with CDM & James Crook TM3-Component&Costs_0707
