Reverse Osmosis is the best water for a serious gardener. It allows precise control of the nutrient flow to your plants. Use reverse osmosis if you take care of delicate plant life.
Water Quality for Crop Production Irrigation water quality is a critical aspect of greenhouse crop production. There are many factors which determine water quality. Among the most important are alkalinity, pH and soluble salts. But there are several other factors to consider, such as whether hard water salts such as calcium and magnesium or heavy metals that can clog
The membrane life for a common RO membranes is unaffected by pH as long as pH is in 6-9 range. pH on the extreme points of membrane tolerance (2 and 12) affect other components of a membrane module and will lead to a shorter module life.
With this in mind, the difference between a single pass RO system and a double pass RO system is that with a double pass RO, the permeate from the first pass becomes the feed water to the second pass (or second RO) which ends up producing a much higher quality permeate because it has essentially gone through two RO systems.

Reverse osmosis (RO) is essentially a pressure-driven membrane diffusion process. In practice, RO membranes retain 95–99% of the dissolved solutes (organic and inorganic) from the feed stream into the concentrate, while the permeate can be considered as high-quality water. Therefore, RO is classified as a concentration process.
Water treatment and desalination plants require much more than monitoring the water quality of the final product to meet these challenging conditions. Today's business requirements demand improving processes, all while lowering costs. For water treatment plants, this means more reliable and stable operations with minimal human resources.
Reverse Osmosis (RO) Water Quality 06-27-2013, 04:31 PM. I'm reading a lot of threads about water quality and RO filtration, but what I want to know is what to expect for a water profile for RO water. I assume not all RO filtration systems are created equal, and so I should expect different mineral profiles in RO water from different filtration ...
ultraviolet disinfection units, reverse osmosis units, ultrafilters and storage tanks. The components of the systems are determined by the quality of feed water and ability of the overall system to produce and maintain appropriate water quality. Failure to ensure adequate water quality may have dire consequences to patient safety and welfare.
