This document provides guidelines for cost analysis of the use of reclaimed water in industrial cooling systems. This document is intended for new-built industrial cooling systems using reclaimed water as make-up water, in which the reclaimed water originates from industrial wastewater and is generated through wastewater treatment systems for reuse. The source of industrial wastewater is from all the production plants inside the enterprise. In this document, the levelized cost of cooling water (LCOCW) is used to compare and determine which industrial cooling system is more expensive per-kilowatt-hour heat removed. Use of reclaimed water will have a direct impact on the operating cost of cooling systems and the environment. External benefits, including positive externalities and negative externalities, are provided in Annex A, which considers environmental, social and financial elements. This document is intended for all types of stakeholders involved in reclaimed water use in new-built industrial cooling systems. This document aims to ensure consistency within any organization engaged in reclaimed water reuse. This document provides a broad framework within which costs for new-built industrial cooling systems using reclaimed water can be assessed. The currency used is local currency (LCY).

This document defines terms related to industrial cooling water systems and specifies technical guidelines for the use of reclaimed water for make-up water purposes water in industrial cooling systems. It provides a basic framework for consideration in the design and operation of industrial cooling systems using reclaimed water. The aim of the document is to promote and to help the implementation of the use of reclaimed water in industrial cooling systems. It provides: — Terms and definitions; — Technical guidelines for the use of reclaimed water in industrial cooling systems. This document is applicable to cooling systems that are considered to work as auxiliary systems for the normal operation of an industrial process. However, the operation of a cooling system in relation to process safety is not covered in this document. In addition, some environmental concerns also need to be taken into consideration, for example the drift control or the use of some persistent biocides. This document can be used to encourage consistency within any organization engaged in the use of reclaimed water.

New findings in the field of swimming pool water and bath water hygiene as well as technical development of the corresponding treatment processes necessitated a revision of the standard series DIN 19643. As a result the standards - DIN 19643-1 "Treatment of water of swimming pools and baths - Part 1: General requirements"; - DIN 19643-2 "Treatment of water of swimming pools and baths - Part 2: Combinations of process with fixed bed filters and precoat filters"; - DIN 19643-3 ("Treatment of water of swimming pools and baths - Part 3: Combinations of process with ozonization"); - DIN 19643-4 "Treatment of water of swimming pools and baths - Part 4: Combinations of process with ultrafiltration" which have been prepared by Working Committee NA 119-04-13 AA "Schwimmbeckenwasser" ("Pool water") at the Water Practice Standards Committee (NAW) are now available. Part 1 applies for the treatment of water, including sea water, mineral water, medicinal water, brine (including artificial brine) and thermal water in swimming pools and bathing facilities. It does not apply for the treatment of water in family pools and water in facilities with biologically treated water. The aim of this document is to ensure good, consistent quality of pool water with regard to hygiene, safety and aesthetics so there are no concerns regarding damage to human health, especially by pathogens. In this respect the well-being of bathers (for example, by minimizing secondary reaction products of disinfection) shall also be considered. For this purpose, water quality, dimensioning, operating and control requirements are specified. Treatment requirements to achieve this aim are stated.

This Part of this European Standard aims to ensure that the boiler is able to be operated to minimize risk to personnel, the boiler and associated plant components located near it.
NOTE   This European Standard does not aim to achieve optimum economic operation. For certain purposes, it will be more appropriate to optimize the chemical characteristics in order to:
- increase the thermal efficiency;
- increase the availability and reliability of the plant;
- increase steam purity;
- reduce the maintenance costs - repair, chemical cleaning, etc.
This Part of this European Standard sets out minimum requirements for the specific types of water to reduce the risk of corrosion, sludge precipitation or formation of deposits which may lead to any damage or other operating problems.
NOTE   This Part of this European Standard has been prepared on the assumption that the user of this European Standard possesses a sufficient knowledge of the construction and operation of the boiler as well as an adequate appreciation of water and steam chemistry.
