Project Overview

Sodium hypochlorite was added to the storage tank of the chlorinated water supply without any type of flow control, which meant that the level of residual chlorine varied and water outside of the production parameters had to be discarded. On the other hand, the chlorinated water storage tank and the pump were in poor condition and the system did not provide the ideal pressure for some equipment in the plant, causing inconsistent performance due to pressure drops. For these r…

Sodium hypochlorite was added to the storage tank of the chlorinated water supply without any type of flow control, which meant that the level of residual chlorine varied and water outside of the production parameters had to be discarded. On the other hand, the chlorinated water storage tank and the pump were in poor condition and the system did not provide the ideal pressure for some equipment in the plant, causing inconsistent performance due to pressure drops. For these reasons, a new soft feeding pump was installed that met the plant’s pressure and ow requirements, together with an online chlorine monitoring and control system.

Project Results

  • Reduction of groundwater extraction and dumping by 6,600 m3/year.
  • Reduction in chlorine use by 3.8% per year. Approximately 43.8 ton/year.
  • Disassembly of equipment to optimize the process. Electricity and maintenance costs associated with this equipment are no longer applicable.
  • Stable water quality conditions that increase the productivity of the system.
  • Savings of USD 131,000 per year in operating costs
