'tds conductive water controller'

Total Dissolved solids, smaller than 2 microns, refer to any minerals, salts, metals, in the form of molecules, atoms, cations or anions dissolved in water. Total dissolved solids (TDS) comprise inorganic salts (principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides and sulfates) and some small amounts of organic matter that dissolve in water. The TDS concentration is the sum of all filterable substances in water that can be determined gravimetrically. However, in most cases, TDS is primarily comprised of ions. TDS is mainly used in the studies of water quality in the natural bodies of water, including surface and ground sources. Why Measure Total Dissolved Solids? TDS in drinking water can originate from natural sources, urban run-off, municipal and industrial waste, chemicals used in treating water and the actual plumbing infrastructure. While TDS is not considered a primary pollutant, it is an indicator of water quality. The USEPA secondary water quality standard for TDS concentration is 500 mg/L to ensure drinking water palatability. High levels of dissolved solids in drinking water can affect the taste causing it to be bitter or salty. High levels of TDS can also lead to scaling and corrosion in any application but especially in boilers and cooling water.

Conductivity of water allows measuring ionic constituents of all types of water including surface water, process water in water supply and treatment plants. PRINCIPLE Conductivity is the ability of a solution, a metal, or a gas - in brief all materials to pass an electric current. In solutions the current is carried by cations and anions whereas in metals it is carried by electrons. How well a solution conducts electricity depends on a number of factors : • Concentration of ions • Mobility of ions • Valence of ions • Temperature All substances possess some degree of conductivity. In aqueous solutions, the level of ionic strength varies from the low conductivity of ultrapure water to the high conductivity of concentrated chemical samples. Conductivity may be measured by applying an alternating electrical current (I) to two Electrodes immersed in a solution and measuring the resulting voltage (U). During this process, the cations migrate to the negative Electrode, the anions to the positive electrode and the solution acts as an electrical conductor.

TDS is mainly used in the studies of water quality in the natural bodies of water, including surface and ground sources. It is an Microprocessor based online measurement of specific TDS of solution using a TDS cell for R.O plant or D.M plant applications. It enables to measure the TDS without manual balancing and specific TDS is read directly on a digital panel. This is available in panel mounting facility in compact size.
