At present, one method of drinking water disinfection is use of per chlorine. It must be added with a certain amount. There are mechanical devices to do this work which need the energy to perform. Hence, giving attention to energy consumption and access to its supplier resources has special importance. Use of cost effective, recyclable and accessible energies forces the human to take daily efficient steps to optimal use of energy resources. This plan has been performed with the aim of using cheap and recyclable energies in order to injecting per chlorine to drinking water in areas without electrical power or where the problem is energy storage. Apparatus operation method: at present on our country the gaseous, electrical, hydro mechanical devices and a manual method have been used to chlorination. Especially, electrical and gaseous chlorine mixer have been used to inject chlorine to water supply pressure lines. But hydraulic chlorine mixer has the ability to inject chlorine by using hydraulic energy present in water supply pressure line, it means that the device will capture the hydraulic energy, it & inject per chlorine solution to water supply network with this force. Results: after studying and considering the operation method of these devices, research have been done and finally by using cylinder and piston and four containers were designed and made and tested successfully. This set is very heavy and complex. After investigation, a very small and portable set was made of light weight materials (polyethylene and pp) and its complexity has been reduced considerable. The presented sample can be produced in a mass
