Total dissolved solids ( TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular ( colloidal sol) suspended form. TDS are often measured in parts per million (ppm). TDS in water can be measured using a digital meter.
Tax deduction at source. Tax deduction at source (TDS) is an Indian withholding tax that is a means of collecting tax on income, dividends, or asset sales by requiring the payer (or legal intermediary) to deduct tax due before paying the balance to the payee (and the tax to the revenue authority). Under the Indian Income Tax Act of 1961, income ...
Total suspended solids ( TSS) is the dry-weight of suspended particles, that are not dissolved, in a sample of water that can be trapped by a filter that is analyzed using a filtration apparatus known as sintered glass crucible. TSS is a water quality parameter used to assess the quality of a specimen of any type of water or water body, ocean ...
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage. [1] [2] It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed.
Salinity ( / səˈlɪnɪti /) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity ). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰). Salinity is an important factor in determining many aspects of the ...
v. t. e. Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of both water clarity and water quality . Fluids can contain suspended solid matter consisting of particles of many ...
Indian water policy. National Water Policy is formulated by the Ministry of Water Resources of the Government of India to govern the planning and development of water resources and their optimum utilization. The first National Water Policy was adopted in September, 1987. [1] It was reviewed and updated in 2002 and later in 2012.
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water that is fit for specific purposes. Most water is purified and disinfected for human consumption ( drinking water ), but water purification may also be carried out for a variety of ...
