subject: Methods For Cooling Water Treatment For The Water Treatment [print this page] Water treatment system aims at cooling water. There are many different kinds of water treatment systems such as industrial cooling water system, once-through cooling water system, auxiliary cooling water system, closed recirculation cooling water system and opened recirculation cooling water system. Take the recirculation cooling water system for example. It is based on water as medium and can conduct duty-cycle operation, which is made up of cooling device, water pump and pipeline. The cold water flows through the production facilities like heat exchanger, condenser or reactor that need to be cooled down. Then, the cold water rises in temperature. However, such water will be back to cooling device and is sent back by water pump to be used again. If like that, it can save as much as 95% water. As we know, the cooling water occupies about 70% of the total industrial water consumption.
Besides, there are some chemical methods when it comes to cooling water treatment, which includes the treatment for controlling the generation of scaling, dirt, corrosion and microorganism. Such chemical products as disincrustant, anti-blocking agent and prefilming agent play a vital role in the process of cooling water treatment. For instance, industrial discrustant has the function of clearing away the rust and sludge on the pipeline, which can be applied to steel, stainless steel and iron, copper, lead and ceramics as well as plastic. Besides, it is environmental-friendly and has no generation of volatilization gas as well as will not corrode the devices. Meanwhile, it belongs to water-solubility substance and can be added to water directly.
In the meantime, the static electricity method is also adopted by cooling water treatment. It is also called high-pressure static electricity method, whose hard core is static-electricity water processor that is made up of high-pressure direct-current power supply and water processor. Its mechanism is to polarize the water molecules further so as to increase the solubility of calcium carbonate, while the high-voltage electrostatic filed will destroy the cell tissue of bacteria and alga. Such a method has many advantages, such as small size, high efficiency, low power consumption, energy saving, convenient management, durable in use and environmental protection. Maybe, a little defect lies in the unconspicuous inhibitory action towards metallic corrosion.
In our modern times, the cooling water treatment technique is stepping forward with each passing day. We believe it will be more and more impeccable in the near future.
