    systems forms deposits on condenser tubes, tube sheets, and piping systems resulting in unexpected plant downtime for maintenance and/or equipment replacement. Generally, biofouling can affect the condenser performance in a number of ways []. 1. Reduction in the internal diameter of the condenser tubes and intake pipes. 2. Years of laboratory and field experience have shown Spectrus CT to be a cost effective and environmentally preferable alternative to chlorination for macrofouling control in both fresh and salt water. Power generating stations, desalination plants and industrial facilities around the world are now using this technology.

      The use of alternative water-conserving cooling systems is frequently proposed and occasionally mandated as a condition for approval. typically chlorination for biofouling control.   Fouling of Cooling Water Tubes in a Condenser. Posted on 29th December ; in Condensor by Jan de Geest GLM Hydro Condensor Problem Solving: – There is one thing that many falling film- and forced circulation evaporators running under vacuum conditions have in common, the use of a condenser at the end of the evaporation system to condense the final vapors.

    Biofouling or biological fouling is the accumulation of microorganisms, plants, algae, or small animals on wetted surfaces that have a mechanical function, causing structural or other functional deficiencies. Such accumulation is referred to as epibiosis when the host surface is another organism and the relationship is not parasitic.. Antifouling is the ability of specifically designed. Gas chlorination is a process used primarily for water disinfection. Most people are familiar with the use of chlorine in swimming pools to eliminate bacteria and algae buildup. While this is a well-known application for gas chlorination, there are numerous industrial and water treatment purposes that benefit from chlorine water cleansing as well.

The report gives results of a study of methods used to reduce free-chlorine residuals in power plant effluents. Most U.S. power plants use chlorine (28, tons in ) to control biological fouling in their cooling systems, particularly in Alternatives to chlorination for control of condenser tube bio-fouling book condenser tubes.

Using chlorine raises many questions regarding the toxicity of chlorinated compounds which may enter public drinking-water systems.

65 The main trouble of alternative chemicals to chlorination W. Chow, Y. Musali (Eds.), Condenser biofouling control chlorination is still the most common biocide to control biofouling.

The most efficient way to control the process of biofouling is the use of chlorine to inactivate bacteria suspended in the cooling water and attached to the tube wall in the biofilm. The high level of chlorine concentrations often needed to control biofouling has created an. Biofouling of industrial water systems is a problem of considerable technoeconomic significance.

Biofouling is described as undesirable deposition of micro- and macroorganisms on industrial cooling equipment, resulting in operational failures such as clogging of water flow in the cooling water conduits and condenser tubes; reducing heat transfer efficiency, and accelerating pipeline.

With regard to macrofouling control in condenser-cooling systems of power plants, chlorination has been the method of choice for fouling control over the years due to its low cost, easy.

It is estimated that some 17 metric tons of residual oxidants (chlorine) are discharged into the enclosed coastal seawater of Kuwait on a daily basis from power-desalination plants alone.

Alarmed by the unlimited number of reported cases of damage to marine aquatic systems due to chlorine discharge around the world, several alternatives were proposed to control such a massive discharge of.

Chlorination revolutionized drinking water safety and availability, reliably eliminating waterborne diseases that killed many people each year. The understanding and regulation of DBPs continues to evolve, and engineers must continue to weigh chlorination’s benefits against the cost of chemical residuals or alternative treatment.

A traditional chemical way to control microbial growth and biofouling in power plants remains the use of chlorine, in spite of the fact that chlorination was subjected to the environmental authorities attention for more than 20 years, because of its.

Most U.S. power plants use chlorine (28, tons in ) to control biological fouling in their cooling systems, particularly in their condenser tubes. Using chlorine raises many questions regarding the toxicity of chlorinated compounds which may enter public drinking-water systems or harm aquatic organisms in the receiving water.

However, yesterday's solution to slime-fouling problems may not apply today in view of tightening effluent restrictions on chlorine. Qatar decreased the free residual chlorine limit from mg/L to mg/L in cooling water. Faced with strict chlorine emissions standards and the need to adequately protect the integrity of.

Fouling is the accumulation of unwanted material on solid surfaces to the detriment of function. The fouling materials can consist of either living organisms or a non-living substance (inorganic and/or organic).Fouling is usually distinguished from other surface-growth phenomena in that it occurs on a surface of a component, system, or plant performing a defined and useful function and that.

Targeted chlorination for biofouling control in steam electric power plant condenser tubes Miscellaneous Tewari, R.N. The objective of this study was to develop an understanding of the relationships between biofouling, heat transfer, and to assess the technical feasibility of the targeted chlorination (TC) concept as an alternative to.

Chlorine in its gaseous state was discovered by Karl W. Scheele in and identified as an element by Humphrey Davy in Chlorine gas is greenish-yellow, and its density is about 2 times that of air.

When condensed, it becomes a clear, amber liquid with a density about 1 times greater than water.Biofouling is organic debris that adheres to the inside diameter of the tube surface or blocks the intake flow at the tubesheet. All tube fouling will increase flow velocity, reduce heat transfer, increase back pressure and decrease efficiency of the condenser.

Biofouling will substantially increase fuel costs.Previous investigations had identified three major areas for further study: continuous low-level chlorination, dechlorination, and condenser biofouling control.

Continuous low-level chlorination, studied at two locations, one on open coastal water and the other in an industrialized estuarine area, showed that ppM total residual oxidant (TRO.
