1. Importance of treated water

 

Nowadays, treated water plays an important role in human health and life. Treated water helps people to maintain daily activities because we use water to provide food and drink needs, or using for routine like bathing, washing, cooking, etc. Therefore, water must be safe for user’s health, if using an unclean water source it will have a bad impact on human health because water plays an intermediary role to transfer chemicals, bacteria, virus, disease-causing parasites which can not be seen by the naked eye.

At the factories which is specialized in producing treated water, there are always testing room and equipment to measure output water quality to ensure that the concentration of substances like iron, manganum, chlorine, PH, turbidity,.. are in the allowable standard. However, in the process of transportation and distribution to users, water may still be affected by environmental factors or pipeline causing water quality be changed. Therefore, to ensure that the water supplied to users reaches the highest quality we need to add an online water quality measurement systems for monitoring standards such as: residual chlorine, PH, turbidity,

 

2. Chlorine Gas Feed Systems according to residual chlorine or flow

 

Common chemicals and indexes to be noted in water include: Ferrum, Plumbum, residual  chlorine, PH, turbidity… If the content of these substances exceeds the permissible standards, it will be harmful to user’s health. Chlorine is more advantageous than other disinfectants that it leaves a residual amount of chlorine after disinfection which prevents the reinfection of bacteria during the distribution, transportation and storage. In some circumstances, deprived of chlorine in distribution system can cause pollution after treatment.

Water with low chlorine below standard (03mg/liter) is easily infected by microbiology. Conversely, water with chlorine exceed standard (0.5mg/liter) can cause poisoning. Depending on the concentration and exposure time that will be different influential levels. Clinical signs of poisoned people by chlorine are cough, breath heavily, heart attack, pulmonary edema,… If smelling in a long time can cause respiratory infection, long –term contact with eyes can cause cornea wound.

With the advantage of being the exclusive distributor of the Hydro Instruments – a manufacturer of high quality products and equipment for the water treatment industry in the US, we are ready and promptly to respond to different customer needs from specific products, such as:  Residual Chlorine Analyzer, Gas Feed Chlorinator, Chlorine Gas valve, chlorine Conduit and other relevant accessories.

 

3. Popular series of Gas Feed Chlorinator

 

Gas Feed Chlorinator is a device to inject chlorine gas with a specified ratio into the water and operate on vacuum pressure principle. This device is as a water treatment machine, helping to disinfect and purify water for using. Gas feed Chlorinator is a modern equipment that applies science to life and be commonly used for municipal water treatment, swimming pools and waste water treatment.

Gas feed Chlorinator has multiform series (From 200 to 6000). Duc Hung Co‘s engineers will give you the best advice so that you can choose the suitable series.

 

Some popular series are trusted:

 

Series 300

Series 300

 

Series 700

Series 700

 

Series 800

Series 800

 

Series 900

Series 900

 

Gas feed Chlorinator’s design include:

  • Throttle
  • Transforming valve
  • Penstock valve
  • Ejector

Gas feed Chlorinator’s feature:

  • Operates on the condition of vacuum pressure, allowing the valve to open chlorine. If it is not in the condition of vacuum pressure, chlorine gas will be leak out or air will enter then the Throttle will not work or not as expect.
  • Chlorine gas run out, go through one – way Penstock valve and blending into the water according to a carefully fixed ratio, ensuring the safest and most effective.

 

4. Automatic Tank Switching Systems

Automatic Tank Switching Systems by electricity

 

Hydro Instruments Gas switchover systems allow the conversion from an empty tank to a reserve tank for continuous and uninterrupted operation of the system. The changeover controller is installed near two vacuum regulators and a separate flow controller. Auto-Switchover is operated on the principle that the valve opens and allows chlorine gas in the first tank go through, when the first tank is empty of chlorine gas, the vacuum increase, the Auto-Switchover closes the first gate and opens the second gate to allow chlorine gas in the second tank go through. Both chlorine tank open valve while the system is operating, a cycle is repeated when we replace the empty tank with a new one.

When the operator replaces a new chlorine gas tank, this will act as a reserve tank. By this way, the operator will reduce contact with chlorine gas, ensuring the systems operate continuously.

For systems with low pressure, less than 0.2kg/h or intermittent operation, the Auto-Switchover can supply gas for each cycle if required. This function is simply conduct by closing the valve of the tank in use, the Auto-Switchover uses the second tank, then open the first tank, close the second tank. By this way we have a desired opening and closing cycle, do not adjust the systems.
