Meeting Environmental Standards for TDS in Wastewater Treatment

TDS Overview

Total Dissolved Solids (TDS) measures the sum of all inorganic and organic substances dissolved in the process. The solids must be small enough to survive filtration through a sieve but not so small that they are ionized or colloidal. They need to stay suspended! TDS sensors measure both soluble compounds such as salts and minerals and insoluble particles like dirt.

Monitoring the TDS to determine the quality and purity of the process is an essential consideration for companies looking to measure TDS in applications such as; cooling tower blowdown, boiler blowdown, or incoming raw water. These tools can analyze how much salt content exists in any given sample, which can then be used to trigger an alarm before scale starts building up. This can cause heat transfer efficiency issues as well as costly repairs and downtime.

Sources of High TDS

TDS are typically found in all freshwater systems. TDS is created when water comes into contact with the earth’s minerals. Some examples of this include; agricultural run-off that occurs during and after heavy rainfalls, snowmelt, leaching of soil contamination where fertilizers have been dumped on top of crops year after year without tilling deep enough to go below the surface root zone (the area just beneath plant root zones).

Importance of Monitoring Trace levels of Dissolved Oxygen

Image
Monitoring trace levels of dissolved oxygen (D.O.) accurately using a dissolved oxygen probe can be essential for many industries such as: power generation, semiconductor manufacturing, food and beverage as well as breweries. Dissolved Oxygen removal from any steam and water system is of major importance. Monitoring the D.O. levels to determine the amount of oxygen can help to reduce corrosion on metal parts which in turn can save time and money on costly repairs and maintenance. Dissolved Oxygen and Water Quality Overview Oxygen is a common element contributing to corrosion reactions. This corrosion reaction provides the need for low level (trace) D.O. control using a dissolved oxygen monitoring sensor. If dissolved oxygen goes undetected it can be responsible for costly replacement of piping and equipment caused by corrosive attack on metals. For more visit source .

Managing Trace-Level Dissolved Oxygen

Image
Dissolved Oxygen Overview Trace levels of dissolved oxygen can be measured at parts per billion (ppb) or micrograms per litre (µg/L) using a dissolved oxygen meter . Online measurement technology in this concentration range is usually different from that for parts per million (ppm) measurements, One of the problems of dissolved oxygen is that it can cause pitting and damage to various components of boiler systems, such as condensate lines and economizers. Thus, one of the primary uses of a dissolved oxygen monitor is for boiler water for corrosion control. Optimizing Dissolved Oxygen Measurement Device Sensitivity When you’re installing a new membrane module on your dissolved oxygen analyzer, it usually takes the unit about 24-48 hours to reach peak accuracy and sensitivity. Keep in mind that this is in ideal, low-oxygen conditions Dissolved oxygen sensors that have been in service for a period of time will respond much quicker than a newly-installed sensor.
