This short article is about the treatment of wastewater. Wastewater treatment describes the process used to convert wastewater or sewage, water that has been used in some form of process and has become contaminated making it unsuitable for further use, or water that is no longer required into an effluent that can be either returned safely to the water cycle with minimal environmental issues or reused for either industrial or domestic consumption.
This short article is about the treatment of feedwater in boilers and steam generating systems and how it should be dealt with to ensure good performance. The term feedwater is usually associated with the operation of larger, industrial sized boilers or steam generators and is an important part of the steam generating process.
Wastewater, or waste water as it is sometimes written, is water that has been used and undergone a reduction in quality from its original state. Wastewater can come from a variety of uses including commercial, industrial, domestic, farming and agricultural activities, storm-water or surface water runoff, and from sewer inflow or infiltration.
This short article is about steam boilers. A typical steam boiler is formed as a closed vessel with in which water or some other liquid is heated to elevated temperatures. The water used in a boiler is not necessarily heated to its boiling point although most often it is. Once in operation the heated water or liquid exits the boiler system where it is used in various industrial processes or heating applications, including water heating, central or space heating, steam-based power generation, cooking, and disinfection and many more applications.
The cleaning, disinfection and chlorination of water systems is an essential activity that helps maintain good standards of water hygiene, especially in domestic water systems where microbial contamination can lead to serious problems. Cleaning and chlorination activities involve the addition of chlorine, a cost efficient but very effective disinfectant, to a water supply at a specific concentration, and for a specified period in order to clean and disinfect the water system, pipework and water tanks.
This short article is about industrial cooling towers and cooling systems used in industrial and large scale process applications. The cooling towers used in industrial and process applications are typically used to remove heat from processes involving heat generation, machinery or materials that have been heated and then require cooling.
BSRIA Guide BG 50/2013 – Water Treatment for Closed Heating and Cooling Systems was published in October 2013 and was written to replace (in part) AG 2/93 Water Treatment for Building Services Systems in relation to closed water system applications.
This brief guide is about heating, ventilation and air conditioning systems, often abbreviated to HVAC. The cooling towers used in heating, ventilating and air conditioning systems are primarily used to dispose or reject to atmosphere any unwanted heat generated from a chiller or cooling system.
