Industrial Water Treatment Operation And Maintenance
INTRODUCTION TO INDUSTRIAL WATER TREATMENT
1-1 PURPOSE AND SCOPE. This UFC provides an overview of industrial water treatment operations and management. As used in this UFC, the term “industrial water” refers to the water used in military power generation, heating, air conditioning, refrigeration, cooling, processing, and all other equipment and systems that require water for operation. Industrial water is not the same as potable water. Industrial water is never consumed or used in situations that require a high degree of sanitation. Industrial water requires water preparation or chemical treatment, or both, to avoid the problems described in paragraph
1-1.2. Water preparation and chemical treatment requirements are described in Chapters 2 through 5 according to the type of system in question. The Navy has special uses for shore-to-ship steam. The Naval Sea Systems Command (NAVSEASYSCOM) shore-to-ship steam purity standards are described in Chapter 3. Examples of industrial water systems and their uses are
• Steam Boiler Systems. (See Chapter 3.) Steam uses include space and hot water heating, sterilization, humidification, indirect food processing, and power generation.
• Cooling Water Systems. (See Chapter 4.) Cooling water is used in cooling towers, evaporative coolers, evaporative condensers, and once-through systems. Applications are broad, ranging from simple refrigeration to temperature regulation of nuclear reactors.
• Closed Water Systems. (See Chapter 5.) These include closed hot water, closed chilled water, and diesel jacket systems.

Finnish Industrial Wastewater Guide
Introduction:
This guide describes Finnish practices for managing industrial wastewater and provides instructions for drawing up an industrial wastewater agreement. The purpose of this guide is to provide support for all those who are involved in decision-making concerning the conveying of industrial wastewater to sewers and the safe treatment of it at municipal wastewater treatment plants. The guide describes the industrial wastewater related legislation currently valid in Finland, information on different types of industrial waters, instructions for preparing an industrial wastewater agreement, formula of increased fee, monitoring of industrial wastewater and practical examples of functional solutions. The guide describes the various stages in drawing up an industrial wastewater agreement and matters that have to be taken into account in preparing such an agreement. The aim of this guide is to provide as many concrete examples and
instructions as possible. However, when preparing an industrial wastewater agreement, it is always recommended to use case-specific discretion and take the local circumstances in account. The specific properties of industrial wastewater must be taken into account in the
industrial wastewater agreement. The quality of wastewater conveyed to the sewers has impacts on the occupational safety of the employees of the water utility, the condition of the sewerage network and equipment of the treatment plant, the operation of the
treatment process, the sludge quality and the state of the recipient water body. All these aspects must be taken into account in the agreement.

An Industrial Facility’s Guide To Cooling Tower Water Treatment
For an industrial company using a cooling tower for its facility, some type of cooling tower water treatment system is usually necessary to ensure an efficient process and lengthy equipment service life.If cooling tower water is left untreated, organic growth, fouling, scaling, and corrosion canreduce plant productivity, cause plant downtime, and require costly equipment replacements down the road.
