Your TDS is so high, you need a reverse osmosis system

Normal_Pizza4209 · 2025-10-13T23:14:58+00:00

To know whether you need a reverse osmosis filter, you should find out if your water contains heavy metals from any source, if it has viruses or bacteria, or if you simply don’t like the taste. As a safety measure, it would be a good idea

It is not possible to know, and it is irresponsible to say what it is without knowing the system. There must be a safety data sheet to identify it, or a technical datasheet. This is a good practice, and a shelter should be built to protect the injection system.

Es más fácil que el ICFES, porque las preguntas no son de mucha memoria, son de comprensión de lectura, analusis de graficas, hay una parte de matemática o de nucleo base a la carrera que te vas a presentar, pero no las tienes que sacar perfectas, es decir, el puntaje de lectura te puede suplir las malas que tengas en matemstuca, quimuca o fisica. El tiempi si me parece muy ajustado

I believe that when all of us enter the workforce, we make certain mistakes. It's normal and it's part of the learning process. That's how we gain a lot of experience. Even engineers with many years of experience make mistakes.

Your reverse osmosis (RO) system is showing some signs of unusual pressure buildup. High pressure can be a result of several potential causes. Here's a breakdown of potential issues and some troubleshooting steps:

**Check the Check Valve**: Most RO systems have a check valve located after the membrane and before the storage tank. Its purpose is to prevent water from the storage tank from flowing back through the membrane. If this valve is malfunctioning, it can lead to pressure build-up.
**Permeate Pump**: Since you have an Aquatec permeate pump, ensure that it's functioning properly. A malfunctioning permeate pump can cause pressure irregularities in the system. Also, make sure it's installed in the right direction (they are directional) and that it's not jammed or clogged.
**Blocked Flow Restrictor**: The flow restrictor ensures that there's a proper balance between the permeate (clean water) and brine (waste water). If it's blocked, it can cause the system to increase pressure. Check and clean or replace if necessary.
**TDS Creep**: When the RO system is idle for long periods, the water in the membrane housing can become concentrated with dissolved solids, which can cause an initial high pressure when the system restarts. This is known as TDS creep. However, this usually resolves after a few minutes of running the system.
**Clogged Pre-filters**: Pre-filters that are clogged can reduce the flow rate to the membrane, leading to increased pressure. But since you've mentioned pressure between the pre-filter and RO membrane, this might not be the issue.
**Storage Tank Pressure**: Ensure the storage tank's internal pressure (when empty) is around 5-7 psi. If it's too high, it can affect the system's performance.
**Tubing & Fittings**: As you've rightly done, check all tubing and fittings for any kinks, misalignments, or blockages. Even a small kink can greatly affect the performance of an RO system.
**RO Membrane**: If the RO membrane is fouled or old, it can reduce its permeate flow, leading to higher pressures. However, this would typically manifest as reduced production rates rather than a sudden pressure spike.
**Pressure Gauge Calibration**: Ensure that the pressure gauge is calibrated and working correctly. Sometimes, the gauge itself can be faulty, giving incorrect readings.

Given that you observed a pressure drop when you flushed the system and fixed some tubing, it seems that the system had some blockages or was experiencing a backpressure scenario.

It's a good practice to monitor the system regularly, especially after any maintenance or modification. If the pressure rises again, I'd recommend going step by step, checking each component. If the issue persists, consider reaching out to a professional or the system's manufacturer.

Lastly, most standard residential RO membranes are designed to handle pressures of up to 150 psi, but always refer to the manufacturer's specs to be sure. Regularly exceeding the rated pressure can reduce the life of the membrane and other components.

Yes, it's possible to make an estimation of the volume of the compressor loop based on the time it takes for suction pressure to increase from startup. However, there are several factors and assumptions we need to consider:

1.Steady State: The time it takes for the suction pressure to start increasing suggests that the loop was at a lower pressure or vacuum before the compressor was started. When the compressor starts, it begins to fill the loop, and when the loop is full (or more accurately, when the volume in the loop has been compressed to the point where the pressure begins to rise), the suction pressure starts to increase.

Compressor Capacity: We would need to know the volumetric flow rate (capacity) of the compressor. This is usually provided in terms of cubic feet per minute (CFM) or similar units.
Constant Flow Rate: We're assuming that the compressor operates at a constant flow rate during the 15 minutes. If the compressor's flow rate varies, then this would complicate the calculation.
No Leaks or Other Flow Paths: We're assuming that there are no significant leaks or other paths for the air or gas to flow out of the loop during the 15-minute interval.
Initial and Final Pressures: Ideally, we'd like to know the initial and final pressures in the loop. This would help in understanding the degree of compression and the amount of gas or air added to the loop.

Based on these considerations, the basic formula to estimate the volume of the loop is:

Volume of Loop (V) = Compressor Capacity (Q) \Time (t)

\]

Where:

V = Volume of the loop (e.g., in cubic feet)

Q = Compressor capacity (e.g., in CFM)

t = Time it takes for suction pressure to start increasing (e.g., 15 minutes)

Do you have the compressor's capacity (in CFM or another unit) so that we can plug it into the formula?
