There is no real optimal pH. The best pH from rejection point of view for thin film composite membranes.
Silt Density Index (SDI) is an empirical test developed for measuring the rate of fouling of nano filtration (NF) or RO membranes. It represents the potential for fouling of the membranes by finely suspended particles present in feed water to the membranes.
Freezing can disrupt the structure of cell membranes, causing increased membrane permeability. This can lead to the leakage of cellular contents and potentially cell death. Additionally, ice crystal formation during freezing can physically damage cell membranes, further compromising their permeability.
Osmosis is the water molecules diffusion across the cell membranes. More informations can be find at en.wikipedia.org/wiki/Diffusion
Distilled implies boiling, Reverse osmosis implies the use of semi-permeable membranes. I say "implies" because there's a lot of cheating in the bottled water industry.

ORP is a measurement of the oxidizing potential of water. ORP analyzers use an electrochemical sensor, and measure in millivolts. Chlorine and other oxidizers can damage most RO (reverse osmosis) membranes, so if water treated with chlorine (e.g. tap water) is used as the feedwater for the RO unit, the chlorine must be removed prior to entering the membranes. Chlorine is removed either with activated carbon filters, or with a chemical dechlorinator, such as sodium bisulfite fed just prior to the membranes. ORP meters are used at the membrane inlet to monitor and adjust the feed of the bisulfite, or to indicate that the carbon is becoming exhausted.
brake leakage? or vacuum assisted vacuum leak?
Sodium metabisulfite (SMBS) is used in reverse osmosis (RO) plants as a reducing agent to remove chlorine and chloramines from the feed water. These chemicals can damage the RO membranes, so SMBS helps protect them from degradation and prolong their lifespan. SMBS also helps to prevent biological growth in the RO system.

I couldn't find on the web how it is pronounced but if it reads /ro zy an/ the Japanese reading for it would be ロジアン /ro ji an/.
If you hear the ro! ro! ro! ro! sound in front of the arrow thing the arrow thing will eat you!
Ro Ro is a "Roll On, Roll Off Vessel"
Angela Ro Ro was born in 1949.
There are several formulas to find out leakage current, but one is the general electric current equation. This electric current equation is I=Qt.
