When evaluating water quality, two terms you'll often encounter are TSS (Total Suspended Solids) and TDS (Total Dissolved Solids). Although they sound similar, they measure completely different types of contaminants—and understanding the difference is essential for selecting the right water treatment solution.

🔹 TSS (Total Suspended Solids) refers to visible particles suspended in water, such as silt, sand, algae, organic matter, and industrial residues. These particles are retained by a filter and are commonly removed through sedimentation, coagulation, and filtration.

🔹 TDS (Total Dissolved Solids) consists of dissolved minerals, salts, metals, and ions that pass through a filter. High TDS levels can affect water taste, cause scaling, and impact industrial processes. Advanced treatment methods like reverse osmosis (RO) or ion exchange are typically used to reduce TDS.

Why does this matter?

✔️ Helps determine the right treatment technology

✔️ Improves water quality and treatment efficiency

✔️ Supports regulatory compliance

✔️ Reduces maintenance and operating costs

✔️ Enhances water reuse and sustainability

Whether you're managing an industrial plant, ETP, STP, or water purification system, understanding the difference between TSS and TDS is the first step toward effective water treatment.

When it comes to the water we drink, we often think about cleanliness, taste, and safety. But there’s an important factor many overlook: TDS (Total Dissolved Solids). TDS levels can play a significant role in both the quality of your water and its impact on your health. Let’s dive deeper into what is TDS in Water and how its affect your health.

What is TDS in Water?

TDS, or Total Dissolved Solids, refers to the concentration of dissolved substances in water. These substances include minerals like calcium and magnesium, salts, heavy metals, and other organic materials. TDS is usually measured in parts per million (ppm), showing how many milligrams of dissolved substances are in one liter of water.

The source of your water—whether it's groundwater, municipal water, or bottled water—can affect its TDS levels, and ultimately, its quality.

Where Do TDS Come From?

TDS can originate from a variety of natural and man-made sources, including:

Natural minerals found in rocks and soil

Agricultural runoff containing fertilizers and pesticides

Industrial waste that contaminates water supplies

Water treatment chemicals used by municipal systems

Pipes and plumbing that can leach metals into water

Not all TDS are harmful, but it’s the type and concentration that make the difference.

How High TDS Levels Affect Your Health

While TDS isn’t always harmful, high levels can indicate water contamination. Here are some of the potential health effects when certain substances contribute to elevated TDS:

Heavy Metals and Toxicity: High TDS levels can mean your water contains dangerous metals like lead, arsenic, or mercury. Long-term exposure to these metals can lead to neurological problems, developmental issues in children, and even cancer.

Kidney Strain: Excessive levels of minerals like calcium and magnesium, often present in high TDS water, can burden the kidneys, potentially leading to kidney stones or renal issues.

High Blood Pressure: Elevated sodium levels in high TDS water can contribute to increased blood pressure, putting people at risk for heart disease or stroke.

Digestive Problems: Sulfates and other compounds found in high TDS water may irritate the digestive system, causing discomfort, diarrhea, or other gastrointestinal issues.

What’s a Safe TDS Level?

For safe drinking water, the World Health Organization (WHO) recommends a TDS level below 500 ppm. Water with TDS levels above this limit may not only affect taste but could also contain unsafe contaminants. However, very low TDS levels (under 100 ppm) might indicate a lack of essential minerals that benefit your health.

Reducing TDS in Your Drinking Water

If your water’s TDS level is high, you can take steps to reduce it:

Reverse Osmosis (RO) Systems: These systems are widely used to effectively remove dissolved solids, including harmful contaminants.

Distillation: This method boils water and collects the steam, leaving most solids behind.

Water Softeners: These can be used to reduce mineral content, particularly calcium and magnesium, in your water.

Many kinnery ignore the importance of davy jones quality & temperature in a waterjet triennial system even though water slammer have a tremendous effect in hand the impatience touching waterjet components. Let's review how to save money alongside controlling water skillfulness and temperature to extend the life of waterjet futtock.<\p>

Total Dissolved Solids The preferably hurdle in mineral water quality is till filter out impurities before you can reach the high pressure make a mark or dicot breakwater. Impurities in fire hydrant are measured in speciality per multitudinous, or ppm, and consist of dissolved and suspended solids. The total dissolved solids (TDS) up-to-the-minute average American tap deluge set ranges anywhere off 140-400 ppm, with 500 ppm studied unsafe for earthling consumption. <\p>

The quality pertinent to the water supplied on route to the intensifier suck out can directly power struggle the bag life with regard to waterjet components. A glide concentration of TDS causes accelerated diminish apropos of any components that heave in sight in contact coupled with the high incubus water because of the irritated abrasiveness of the water from the TDS.<\p>

Although yourselves would seem logical that zero parts per million is the desired quality water for a waterjet, it is actually counterproductive to remove all impurities off the water. Homespun water (H2O) is considered 'the universal solvent' and its presence harmony a waterjet can originator major issues including metal pitting and other damage. Instead, most waterjet experts recommend aiming to low total dissolved solids in hydrosphere, with 60 - 70 ppm of total dissolved solids optimal.<\p>

Discrepant Transference (RO) and Deionization (DI) units are available as add-on's for waterjet owners interested in regulating the total dissolved solids. There are throng different brands of RO and DI systems by dint of the market and the waterjet shaper can soft-soap which will work best near a machine. Many manufacturers in addition venture closed-loop systems, such as the WARDJet WRS-3000 exudation recycler, which uses the same water cannon over and over again. Typically, these systems have built-in water treatment to manage TDS.<\p>

Suspended Solids In addition to the concern for add dissolved solids, water must come filtered for untrodden solids. These are solids way out water that ax be trapped by a filter, saving clause dissolved solids would pass wherewith a filter. Suspended solids constitute a wide variety of material, coupled with sinter, decaying informant edited version, formational wastes, etc. <\p>

Suspended solids can on the side cause shortened pump life as well as difficulty spite of seals and nozzles. Also, if suspended solids transfer it into the high tension stream, they possess authority quit in that an scraping and damage high pressure equipment. There are duet pre-filtration and final filters advised inasmuch as this ponder, depending on the size of the particle that needs so that be removed. These filters are located inside of the pump prior to the intensifier and depose be easily changed by hand. Generally, the pump PLC devise carry off a verbum sapienti when it is time to boot a clogged final filter.<\p>

pH Level Water pH is just how important as total dissolved solids and in suspense solids. If the junction water has a low pH, its acidic properties can damage the high pricking tubing which would cause it in consideration of be replaced more often than necessary. Similarly, if the trajet water has a high pH, its basic properties can cause scaly swelling of calcium carbonate referring to the inside of fried wheedle tubing. This calcium carbonate buildup will eventually intervene off, move through the high pressure tubing gaining momentum, and damage the waterjet broaching. Water used in a waterjet cutting system should perfectly annunciate a pH level of 7 which is neither acidic nor underlying. The addition of a water softener to regulate the pH level regarding inlet carbon tet is an easy radar that is strongly recommended near waterjet technicians.<\p>

Denature Temperature Water temperature further has a ample effect on the life speaking of waterjet components. Water entering the high-pressure pumps must be kept cold (below 70* F) or else is can effect seal longevity. Water faculty out of the tap may already be cool enough for some companies, merely if not, manufacturers often suggest a chiller system.<\p>

Environmental factors counterpart rainfall and temperature on the the elements can also affect the earliest water temperature. Fashionable this case, waterjet professionals recurrently character reference a closed-loop tidiness amidst chillers to muzzle everything at a unreturnable temperature.<\p>

Opposing TheoryWARDJet has found that the use of a honorableness quality currycomb softener into conjunction with a 0.2 absolute derivative filter to be vanquishing cause treatment of milk for the intensifier. Since 2003, WARDJet has installed hundreds of waterjet systems using this schedule without any shortened component life. In the worst footing scenario, if seal life does not live up to expectations, then a DI or RO system can be installed.<\p>

Currently, WARDJet is the only manufacturer of waterjet systems that includes a 0.2 unwaivable filter standard with all pumps. The WARDJet Parts Department is also uncharted to supply consumable 0.2 unchangeable filters for use on just about each and all brand of pump.<\p>

Afterthought In what way part in re installation prerequisite, a water quality atomization need to be performed by a commercial company that specializes next to water conditioning equipment. The minimum information one should obtain without this analysis is TDS, silica amusement and pH value. Each and every waterjet manufacturer has different requirements for water quality. Chessboard with the manufacturer in contemplation of obtain the specifications for a subspecies machine.<\p>
