Chlorine pump

Published on by in Technology

I have been asked to design a chlorine pump that will inject chlorine into a transmission main that delivers water from borehole field with a combined discharge of 750M3 per hour.

The connections of the fifteen borehole sources to the transmission main of 450mm diameter was done 187M and the pint of injection is at 191 M.

The horizontal distance from the borehole fields to the point of injection is approximately 1.5Km . The horizontal distance from the chlorination unit to the transmission main is 205 mm.  Is it possible for me to be referred to references that I can follow up on this? I have one week to deliver this project.

Thank you!

  2. May I suggest  using an inline  Zeta Potential Mixer to enhance mixing and reducing the volume of Chlorine required.

  3. Questions.

    • Is the purpose of chlorination, disinfection or any other?
    • What is the feasible chlorine form source, in terms of economics, safety and logistics; Cl2 gas, sodium Hypochlorite or calcium Hypochlorite?
    • It is important a water analysis and testing chlorination with samples of source water.
    • Well water can have iron, manganese  and other components that react with chlorine. Also Trihalomethanes might be a concern. 
    • In absence of information you can use 5 ppm dose value for designing a drinking water. Tha will give you a 200 PPD chlorine gas dosing unit o a 6,24 GPH dosing pump.

  4. Comencemos desde el principio:

    a) Las bombas de  cloro no se diseñan especialmente, sino que se seleccionan entre la gran variedad que hay en el mercado, fabricadas para bombear soluciones de cloro.

    b) Se tienen que hacer ensayos con el agua para determinar la dosis que requiere para que quede un residual de cloro de 1,0 mg/L.

    c) Posteriormente se tiene  que adquirir un dosificador de cloro, que puede ser  para cloro gaseoso, o para de sales metálicas, tal como cloruro férrico.

    d) Se sebe disponer un dispositivo determinar y controlar el cloro residual.

    e) A todo lo anterior hay que agregarle un difusor de cloro, de acuerdo con el tipo a  utilizar (gaseoso o metálico).

    f)) Todo lo anterior es solo para desinfectar el agua cruda , pero está lejos de un tratamiento completo para eliminar los componentes físicos y químicos que exceden los límites exigidos para obtener un agua apta par el consumo humano.

    Si tienen algo más, pueden comunicarse con jlogreir@une.net.co, y gustosamente atenderé sus inquitudes.
