Industrial boilers currently commonly used sodium ion exchange method for water treatment, there is a high rate of boiler discharge, heat loss and other disadvantages. With the development of water treatment technology, the use of reverse osmosis membrane water treatment technology, can effectively remove a variety of ions, molecules, organic colloids, bacteria, viruses, heat sources, etc., is a highly efficient, low consumption, non-polluting water treatment technology, suitable for the treatment of water with high salt content.
The proper treatment of boiler water is essential to ensure that the boiler can operate properly. Various emissions caused by untreated feed water, together with cooling fins or other pipes through which hot water or steam passes, can reduce the efficiency of the boiler or even destroy it. To prevent problems such as scaling and fouling, the water is usually treated before it enters the boiler. This boiler feed water may undergo a variety of different processes, including degassing, filtration and pre-heating.
The installation of a water purification system prior to a boiler feedwater treatment system will remove dissolved and suspended solids and organic matter that may be present in the feedwater. These include：
Calcium and magnesium: known to cause boiler feedwater scaling.
Silicon dioxide: known to cause hard scaling. Silicon dioxide needs to be reduced to low levels to avoid any operational problems.
Iron and manganese: can damage downstream equipment and affect water quality.
Copper: can reduce the efficiency of boiler feedwater equipment when deposited in high pressure turbines.
Magnesium: has the ability to adhere to the inside of the boiler and can also lead to scaling.
Hardness: leads to boiler pipe scaling.
Aluminium: can react with silica to increase scaling.
Dissolved gases: can cause severe corrosion of the boiler due to the presence of oxygen and carbon dioxide.
Boiler water treatment, in short, is the correct purification of boiler water and strict supervision of the quality of steam and water, as a means of ensuring good water quality in boiler water and steam systems and preventing scaling, salt accumulation and corrosion in boilers and thermal systems.
Pre-treatment of boilers is essential to maintain safe and efficient plant operation. Installing a reverse osmosis system will reduce boiler operating costs and reduce drainage time, scaling and corrosion.
Reverse osmosis purification is necessary for the optimum performance of most boiler systems, even for those used purely for heating purposes. When used in conjunction with a boiler system, reverse osmosis does two things.
1.It purifies the water used for cooking and drinking.
For example, if you are using water for food service or brewing purposes, reverse osmosis ensures that the hot water is drinkable without negatively affecting the taste of the product.
2. It protects the boiler from mineral build-up.
When water boils, it turns into steam and disperses into the air as a gas. However, salt and other minerals do not evaporate in the same way that water does. Over time, these minerals can form scale within the boiler system, creating 'hot spots', obstructions and inefficient performance, and in the worst case scenario, system failure. Reverse osmosis helps to keep the boiler itself running smoothly by removing minerals before the water enters the feedwater tank.
Most boilers are fitted with a high quality reverse osmosis system as standard to ensure long lasting, optimum performance of the entire water supply system.
