TYPES OF OOLING WATER SYSTEMS. Cooling water systems remove heat generated from a variety of industrial processes. There are three basic types of cooling water systems: once-through, open recirculating, and closed recirculating cooling water systems. This publication describes once-through and open recirculating systems.

Alternative Water Treatment Technologies for Cooling Tower Applications
This GSA Proving Ground (GPG) project assessed the performance of three alternative water treatment systems (AWT) for cooling tower water treatment applications at the Denver Federal Center (DFC) in Denver, Colorado. Cooling towers are commonly applied to water cooled chilled water plants in medium to large commercial buildings and are the point in the system where heat is dissipated to the atmosphere through the evaporative cooling process. Cooling towers also consume a large amount of water. Cooling tower related water consumption is one of largest potable water loads within buildings in the United States, with over 26% of water use associated with heating and cooling. Reducing water consumption is a priority for the General Services Administration (GSA) due to Executive Order 13693, Energy Policy Act of 1992, and regional water shortages. These factors have brought about the investigation of cost effective opportunities to reduce water use, such as AWT technologies for cooling towers. The current state of water treatment in GSA buildings is to use conventional chemical based cooling tower water treatment to maintain cooling tower water quality and contract out this specialized service to a third-party company specializing in such service.

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.

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.
