Disinfection CLO2 electrical power demand
Disinfection CLO2 electrical power demand
(OP)
The client wishes to change from CL to CLO2 to be manufactured on site from sodium Chlorite and HCL. water is desalinated water at 48 degree C volume is 50 Million gallons per day - dosing at 2 ppm, I am trying to prepare a budget estimate for the supporting infrastructure works. Question is does anyone have a ball park estimate for the electrical power demand of a CLO@ plant. I have been given a figure of 2MW electrical power demand for the chillers - This sounds excessive ?





RE: Disinfection CLO2 electrical power demand
The chiller is not for the CLO2 production directly but for cooling of the desalinated water. However this is unusual because most RO membranes unless they are the heat sanitisable type used for dairy production typically have a 40-45 degree C limit.
The final decision would have to be very site specific but you might use an evaporative type cooler to achieve the cooling you need for this project. It could be an open cycle once through type unit or perhaps a closed lop unit with a heat exchanger. Raw water chemistry may well dictate this decision. Power would be needed for fans and pumps and for a plant of this size power demand will be considerable. The amount of temperature reduction, water quality, closed loop/open loop , ambient temperature and humidity will all influence the power demand.
Chlorine dioxide generation itself is not particularly energy intensive but will require pumps, mixers , valving and instrumentation, to operate and monitor the system. Without know specifics it is difficult to advise, but you will probably need to generate 600-700lbs of chlorine dioxide per day.

RE: Disinfection CLO2 electrical power demand
Why is it necessary to cool the desalinated water ? I assumed that only the "motive" water being drawn off the supply and run through the plant would need to be chilled.
We do not need to get involved in the process - our task is to provide the infrastructure - electrical power supply, pumping stations reservoirs etc. The process plant will be designed and constructed on an EPC basis by others.

But this requirement would be the same regardless of whether chlorine or chlorine dioxide was being used.

The CLO2 plant would be very unlikely to be 2MW.
I would be suprised if it was 200kw.
