PETIÓN® is the most advanced antibiological growth and anticorrosive system for seawater circuits that can be found in the market. applying The highest technology in electrolysis, the two main objectives are reached: The total cleaning up of molluscs, crustaceans and algae in one hand and, on the other, the protection against corrosion in the whole system where the seawater flows, either in pipelines, valves or any other machinery.
The use of PETIÓN® on all kind of ships, vessels, petrol platforms, and inland seawater refrigeration systems, has been crucial in the maintenance of them.The PETIÓN® system is a PETER TABOADA's® patent. Built with the best components and materials after several years of research and development, the PETIÓN® system is the most cost-effective and least expensive by its performance, low energy, and maintenance expenses.
Within the advantages we have found, regarding to other systems, we can mention:
1.- It avoids molluscs, crustaceans and algae incrustations, which reduces substantially the maintenance cost of pipelines, sumps, valves, seawater inlets, intercoolers, and condensors.
2.- Eliminates sludge formation.
3.- Eliminates corrosion in the pipeline, increasing its duration and protecting it. This means savings, as there is no need to replace them from time to time.
4.- It increases refrigeration in engines, refrigeration equipment, condensors, intercoolers etc. That means energy savings.
5.- It increases seawater circulation in pumps, which increases its efficiency.

Compact systems designed for the protection of the vessel seawater pipes, as well as the cooling circuits of main and auxiliary engines.
QTM ANTIFOULING system is based on electrolysis principle, generating Cu+2 ions, which are able to avoid biological growth and fouling problems inside of piping and circuits, besides of eliminating the already existing, this way preventing the blocking of pipes.
Every case has to be studied by our technical department, designing the most suitable system, in a tailor-made basis, for every customer.

Deaerator eliminates dissolved gases(especially oxygen and carbon dioxide), which can cause erosion inside of pipe and heat exchanger, in feed water and plays a role as an equipment such as heater to heat feed water and keep NPSH of feed water pump constantly.
Spray & tray type are usually used for onshore plant and spray & scrubber type are mainly used for offshore vessel. Dong Hwa has been testing and developing main parts of deaerator like spray, tray and scrubber, and steadily researching for upgrading those performance so far.
Also, we are truly trying to meet customer's expectation with batch processing system ranging from performance design, hardness design, procurement to manufacturing and delivery

The small portion of the electromagnetic spectrum that have wavelength between 100 and 400 NM, is the ultraviolet radiation, the UV-C rays are part of the UV rays, and they are between 100 and 280 NM. The electromagnetic waves, depending on its wavelength and its wave amplitude interact the materia and generate different nature effects. Because of its powerful germicide effect is very important the UV-C with L=254 NM radiation.
ADVANTAGES:
This technology gives lots of advantages, mainly we can say:
Ecologic treatment, no chemical produccts are added. Thare are no alterations in the organoleptic characteristics.
There is not risk for over dosing, or alteration of the water composition.
There is not creation of toxic products. It cannot be avoided when chlorine is used.
Fast purification in few seconds (just the time of the water passing through the collector) and storage tank is not necessary.
Compatible with every water treatment technologies (activated carbon, softeners, reverse osmosis, etc.)
Low price and guaranteed results because of its low electrical consumption and economic maintenance.
UV lamps replacement every 10.000 hours of working

Water sterilization systems by ultraviolet radiation.
Based on a electromagnetic wavelength of A=254 nm, the UV rays interact with the organic matter in the water, reaching its 100% sterilization.
The UV sterilizers QTM uv series are characterized by a compact construction and a high degree of efficiency concerning disinfection and energy consumption. The construction design follows current standards and regulations.
UV sterilizers are equipped with polished high quality stainless steel reactors (AISI 316-Ti), so that they can treat high salinity water, therefore being ready to work in the strictest conditions on board vessels. They can be used also for the disinfection of high temperature water, specially indicated to protect against legionella.
The used UV-lamps are characterized by a long durability and a high degree of efficiency as well. The compact construction design enables an easy replacement of the UV lamps at the end Df their useful life. You don't need any tool. Also replacement and cleaning of the quartz pipe can be arranged easily.
