Bencho chlorinator has been designed as per IS:10553 part II 1983 specification by taking into account of its physical and chemical properties – viz its reaction with metal, solubility in water, behavior at different temperature and its hazards.
Chlorine gas, greenish yellow in color, two and half times heavier than air reacts with almost all metals. Hence we are using only Teflon, Silver, and Hastalloy-C the highly resistant engineering alloys for chlorine gas.In our chlorinator chlorine gas is passing through filters and valves made out of Teflon. Since the Teflon is having very low mechanical strength we are using PVC composite FRP for outside protection.
Purpose of chlorination for potable and swimming pool water
Certain diseases like infectious Hepatitis, Typhoid, Cholera etc. are caused through impure water. In addition, some types of bacteria cause distaste and impart color and odour to water. The only and readily available and economical solution for the above is chlorination.
Surface water resources, normally are polluted. It needs extensive and through treatment and to meet this requirement chlorination is performed. Chlorine when added to water takes 15-30 minutes of retention time to reach with all substances present in water.
Design & Operation
Bencho made Vaccum feed Chlorinators are having the latest Vacuum Technology. This Semi automatic Chlorinator will develop the required vacuum (300hg) with a water pressure of just 0.5kg/cm2 ,which is suitable for upto 5kgs/hr Chlorinator. The Chlorine gas from the cylinder enters the chlorinator where it is filtered to remove any foreign material which might be present. Water under pressure flows through the injector at high velocity and causes a vacuum which opens a spring opposed check valve opens, a vacuum signal is carried to the vacuum regulator, mounted on the cabin. This vacuum causes the diaphragm to open the chlorine inlet safety valve to admit the gas into the regulator. The spring opposed diaphragm the vacuum at this point.
The gas passes through the flow meter and the rate control valve and then to the injector where the chlorine is thoroughly mixed and dissolved in the water and carried to the application point as a solution. If the water supply to the injector is stopped, or the operating vacuum is lost for any other reason, the spring loaded gas inlet valve immediately closes to isolate the chlorinator from the gas supply, any gas, under pressure which might enter the regulator is vented from the system through built-in pressure relief valve, Of the source of chlorine gas is exhausted or the gas line plugged and excess vacuum valve in regulator closes to prevent any moisture being pulled back into the regulator or the gas supply lines. The ejector is provided with a diaphragm operated back check valve to insure that water does not leak back into the regulator when the system is shut down.
Optional Facilities and Guarantee
We can supply a chlorinator with automatic regulation. This automatic regulator will stop the entire chlorination if found any leakages in the plant. It also will give an alarm to the operator.
We take utmost care in manufacturing our chlorinators. The equipment is guaranteed for a period of five years against any manufacturing defects. If found any fault due to materials or workmanship during guarantee period we will replace the equipment immediately on free of cost.
