Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Scale is formed by salts that have limited solubility but are not totally insoluble in boiler water.
If unchecked, scaling can begin to act as an insulator and reduce overall boiler efficiency. Corrosion can damage the internal workings of your boiler in two possible ways — general and pitting. General corrosion creates damage all over the system. Pitting creates localised corrosion of small parts of the boiler, such as in tubes. Boiler deposits can also cause plugging or partial obstruction of tubes and in some cases, scale build-up will cause a tube to overheat and potentially rupture.
This involves the reduction or removal of impurities from water outside the boiler. There are many types of external treatments including softening, RO or Demin plants which can be used to develop a tailored solution.
This involves the conditioning of impurities within the boiler system. Internal treatment may be used alone or in conjunction with external treatment. D-Tech Chemicals purpose is to properly react with feed water hardness, condition sludge, scavenge oxygen and prevent boiler water foaming.
Taking preventative action to reduce the effects of scaling has many advantages including increased energy efficiency, improved water consumption and lifespan of the equipment.
Scale deposits form when the solubility of dissolved minerals in cooling water is exceeded. Cooling towers function by evaporating a percentage of the water into the atmosphere. This water is pure and does not contain any of the dissolved minerals found in the makeup water. As the evaporation process continues, the scale-forming minerals concentrate in the water. If left unchecked, the solubility of the dissolved minerals is exceeded, resulting in precipitation of these salts as scale deposits.
Scale interferes with heat transfer by forming an insulting barrier on heat exchange surfaces. Scale also promotes corrosion, restricts water flow and increases water consumption.
Microbiological fouling in cooling systems is the result of abundant growth of algae, fungi, and bacteria on surfaces. Open recirculating systems scrub microbes from the air and through evaporation, concentrate nutrients present in makeup water. As a result, microbe growth is more rapid. This accumulation and excessive growth of microorganisms is known as biofouling and can severely affect equipment leading to reduced performance and efficiency.
By implementing the correct water treatment solution for your cooling systems, you will protect your equipment, increase effective heat transfer, decrease water consumption, increase operational and energy efficiency.
Corrosion in a water transport system is the destruction of materials by chemical or electro-chemical (galvanic) reaction. Most corrosion processes are electro-chemical in nature, like a dry-cell battery. There is a flow of electricity between an area of the metal surface through the solution capable of conducting an electrical current. The eating away of the metal is at the point (anode) where the current enters the solution.
Most closed loop water systems retain water a long time and because of this, any corrosion can result in a gradual buildup of metals in the system causing severe fouling and plugging as well as piping and equipment failure.
Preventing corrosion can be done by using our D-Tech chemical which will inhibit corrosion and increase the lifespan of equipment and piping.
Potable water is the water that humans consume for drinking purposes. If the water is contaminated, it can lead to diseases causing unnecessary altercations and even worse a law suit.
Effluent water contains contaminants from the byproduct of the manufacturing process. These contaminants are often harmful to the environment and not safe for discharge to municipality before being treated accordingly as they exceed municipal discharge laws. These pollutants must be converted, removed or broken down before being discharged to municipality. Not meeting the municipality discharge standard can result in a holt in production or even worse, shutting down of a plant until standards are met.
Pollutants need to be removed, altered or broken down by our range of D-Tech coagulants and flocculants. When implemented correctly, all municipality standards can be met. This will lead to a better environmental footprint for your company and the world.
A Dynamic Aqua representative will do jar tests on site to establish what treatment and solution can be tailored to your plant.
Raw water, depending on its source or quality, must be filtered, treated, or clarified before it can be used as makeup water in industrial and other utility processes. Clarification removes suspended and dissolved solids. Carbon filters are used to remove organics and chlorine. Ion exchange columns are used to exchange an undesirable mineral or salt for an acceptable one. Reverse Osmosis or De-Ionisers are used where ultra-pure water is required.Whatever your raw water quality and process requirements are, we will design a Turnkey solution for you.
