Disinfection of Washing and Cooling Water of Carrots

Post-Harvest Cadiz (Spain)
An Andalusian cooperation located in Cadiz (Spain) strives to increase their farmers sustainable profitability by continuous innovation.

The challenge

Upon arrival at the processing facility, the carrots are washed to remove remaining soil and other dirt and additionally often pass through a hydrocooler to increase preservation. Large volumes of water are required during this process. However, these vegetables grown in open ground can be contaminated with a variety of different pathogens such as Pseudomonas spp., E. coli, Salmonella, Yersinia, and Shigella. The number of pathogens in the water can accumulate rapidly and cross contamination can occur if the microbial contamination of the water is not monitored and disinfected accordingly.

Our solutions

The carrots are washed in two steps. During the first step recycled water is used that is treated with a cationic flocculant to eliminate solids and with a continuous dose of Huwa-San TR-50 for disinfection. During a second washing procedure, the carrots pass through a hydrocooler. The water of this hydrocooler is renewed daily and treated with Huwa-San TR-50.

The results

Huwa-San was proven to be highly effective and ideally suited for maintenance of water quality at the processing facility.

  • Water conservation, resulting in reduced production costs and increased sustainability of the process
  • Highly effective water disinfection that prevents cross contamination
  • Environmentally friendly solution
