1、Designation: D7841 13Standard Practice forSustainable Laundry Best Management Practices1This standard is issued under the fixed designation D7841; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number
2、in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 PurposeThe purpose of this practice is to identify anddefine sustainable laundry Best Management Practices (BMPs)that are used in commercial l
3、aundry facilities to reduce theirimpact on the environment.1.2 It is recommended that users rely on professionaljudgment informed by both environmental expertise and spe-cific knowledge of the intended use of this practice. Thispractice provides instruction on interpretation of the dataobtained. Int
4、erpretation of the data results in a determination ofwhether a laundry implements enough BMPs to be certified ascomplying with the requirements of this practice.1.3 The users of this practice include laundry professionalsand inspectors who possess a broad understanding of environ-mental issues relat
5、ed to the operations and maintenance oflaundry facilities.1.4 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theres
6、ponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

9、fluid exits the boiler for use invarious processes or heating applications.3.1.4 detergent, nsurfactant or a mixture of surfactantsand other chemicals having “cleaning properties in dilutesolutions.”3.1.4.1 DiscussionIn common usage, “detergent“ refers toa family of compounds that are similar to soa

11、 and then releasingthe air at atmospheric pressure in a flotation tank or basin. Thereleased air forms tiny bubbles that adhere to the suspendedmatter causing the suspended matter to float to the surface ofthe water where it may then be removed by a skimming device.3.1.6 material safety data sheet,

Best Management Practices4.1 The implementation or use of the following:4.1.1 Water Reuse TechnologyA technology or equip
20、mentwithin a laundry facility that reuses, reclaims, or recycleswater. The technology or equipment shall be visible, in use anddesigned for the purpose of reusing, reclaiming, or recyclingwater. Examples include: water reuse systems that capture andreuse final rinses drained from washers; water recy
21、cling orreclamation systems that capture and recycle treated wastewa-ter; and special washers (for example, tunnel washers) that usethe same water more than once for washing linen.4.1.2 Boiler Heat RecoveryA technology or equipmentwithin a laundry facility that recovers heat produced from thefacilit
22、ys water boiler system. The technology or equipmentshall be visible, in use, and designed for the purpose ofrecovering heat from the boiler system. An example includes:stack economizers that capture the “lost or waste heat“ from theboilers hot stack gas.4.1.3 Direct-Fired Hot Water Heating SystemA w
