Water is vital for maintaining the health of livestock (e.g., cattle, chickens, sheep, pigs) and optimizing their productivity. Not only does the quantity of water matter, but its quality is crucial for ensuring desired growth and performance.
Farm water sources are diverse, ranging from wells and municipal networks to, less commonly, rivers and other surface sources.
Excluding municipal supplies (with chlorine), other water sources often contain high levels of solids and pathogens. Reverse osmosis technology emerges as the most effective solution, as it mitigates harmful substances present in farm water, safeguarding animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
The application of desalination membranes on international luxury cruise ships has historically been dominated by a few international brands. As these majestic vessels journey across oceans, the quality of feed water, including salinity and temperature, varies significantly. Consequently, the membranes are required to adapt seamlessly to these varying conditions, ensuring consistent and reliable water production to fulfill the demanding requirements of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes demonstrated exceptional performance, excelling in both desalination rate and consistent water production. The water quality achieved by these cutting-edge membranes met, and indeed surpassed, the rigorous standards demanded by luxury cruise ships.
This outstanding achievement led to the replacement of desalination membranes on three additional luxury cruise ships. Proshare's triumphant success in this venture marks it as the first national brand to secure international luxury cruise ship orders for desalination RO membranes, establishing a new benchmark in the industry.
