What are Total Dissolved Solids (TDS)?
TOTAL DISSOLVED SOLIDS One of the measurements that can be taken on swimming pool water is the Total Dissolved Solids level, or TDS. TDS is a measurement of virtually everything dissolved in the water that is not H2O. This includes such components as salts, minerals (like calcium and magnesium), sulfates, silicates, organic and inorganic materials, tanning lotions and oils, sweat, saliva, urine, soap, deodorant, hair spray, colognes and perfumes, plant pollens, pet wastes, spilled food and soft drinks, dirt, lawn and garden fertilizers, etc. Wow! There is quite a lot of dissolved material in that water that is still clear to the human eye! As water evaporates from the pool, the TDS increases because the sun only removes distilled (pure) water and leaves all of the dissolved solids behind (like when you leave a glass of water outside to evaporate, the white crust left behind was “dissolved solids”). The “fresh” water you then use to replace the evaporated pure water also contains its sh
Total Dissolved Solids (TDS) are the total weight of all solids that are dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million. “Dissolved solids” refer to any minerals, salts, metals, cations or anions dissolved in water. This includes anything present in water other than the pure water (H20) molecule and suspended solids. Suspended solids are any particles/substances that are neither dissolved nor settled in the water, such as wood pulp. In general, the total dissolved solids concentration is the sum of the cations (positively charged) and anions (negatively charged) ions in the water. Parts per Million (ppm) is the weight-to-weight ratio of any ion to water. Conductivity is usually about 100 times the total cations or anions expressed as equivalents. Total dissolved solids TDS) in ppm usually ranges from 0.5 to 1.0 times the electrical conductivity.
