1. Permeate flow rate and stabilized salt rejection are determined based on the following standardized conditions:

For NF membranes, testing includes a 2000ppm MgSO4 solution, at 0.48 MPa and 25ºC, with a 15% recovery rate, while for RO membranes, the test uses a 2000ppm NaCl solution,

at 1.55 MPa and 25ºC, maintaining a 15% recovery rate, all prior to any hot water disinfection process.

2. The permissible variation range for permeate flow is +/-15%, with potential fluctuations in final water yield due to

the heat treatment process involved.

Farming applications

In farming, water quality is paramount to ensure the optimal health and productivity of livestock, including cattle, chickens, sheep, and pigs. Both the quantity and quality of water significantly influence the desired growth and performance of these animals.
Farms utilize water from diverse sources such as water wells, civil water networks, and occasionally rivers and superficial sources. Each source undergoes meticulous analysis and treatment to maintain the highest water quality standards.
While water from civil networks is treated with free chlorine, other sources often contain high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven to be the most effective method to mitigate these adverse effects. Contaminated farm water requires comprehensive technological treatment to eliminate harmful substances and protect animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
