There is no real optimal pH. The best pH from rejection point of view for thin film composite membranes.
Yes, RO waste water can be reprocessed through RO systems again. This process is known as concentrate recycling, where the concentrated reject water from the initial RO system is fed back into the RO feed water to increase overall recovery rates and reduce waste. However, multiple passes of reprocessing may decrease the efficiency of the RO system over time.
Making up feed with water having low PH. Feed water getting contaminated with sea water, greese, fatty/fuel oils, CO2, 02 can cause water to become acidic leading to boiler corrosion as well as redusing it PH value. Lot of leakage will also cause more make up water and if regular blow down is not carried out, will cause increase in total disolve solides, thus reducing PH. Also if boiler water treatment is not carried out properly can result in drop in PH.
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.
pH=6,4
The pH of tomato ketchup is 3.85
6-6.5
The pH of RO (reverse osmosis) water typically falls in the range of 5.5 to 7, making it slightly acidic to neutral. The exact pH can vary depending on the source water and the specific RO system used.
To increase the pH of RO water effectively, you can add alkaline substances such as baking soda, crushed eggshells, or a pH increaser solution. Be sure to measure the pH level regularly to avoid overcorrection.

To adjust the pH of RO water effectively, one can use pH adjustment chemicals such as citric acid or sodium bicarbonate. These chemicals can be added in small amounts and mixed well to achieve the desired pH level. It is important to test the pH regularly and make gradual adjustments to avoid drastic changes.
pH scale :)
Let ROH represent the alcoholROH <==> RO^- + H+ Ka = [H+][RO-]/[ROH] Solve for [H+] and take the negative log to get the pH
It is the ratio of permeate over the feed water.
The pH value in boiler feed water is typically maintained between 8.5 and 9.5. This range helps to prevent corrosion and scaling in the boiler system. Regular monitoring and adjustment of pH levels are important to ensure the proper functioning and longevity of the boiler.
RO water or Pete moss maybe ur tap has low pH
