What factors affect the measurement of dissolved oxygen in water? Atmospheric pressure: Higher atmospheric pressure allows bodies of water to retain more dissolved oxygen. The pressure from above allows the water to hold more oxygen molecules. Therefore, DO concentrations are normally lower at higher elevations due to lower atmospheric pressure.

Aquatech China 2021 will be an unmissable event and trade fair with all sectors of the process, drinking and waste water industries presented under one roof,BOQU Instrument: Expert in Water Quality Analysis Instrument Vision : To be leader in water quality monitoring instrument Mission: To be brightest eye for water quality monitoring on earth Value : Customer success,Trustworthy,Teamwork,Open-minded

Calibration Requirements for Suspended Solid Sensor; Comparison Test of Online MLSS Sensor Standard solution 200mg/l, 5000 mg/l, 12000 mg/l. Reverse test the standard solution after calibration, The TSS sensor is qualified if the measured value is within the error range.

Aquatech China 2021 takes place at the newly built National Exhibition and Convention Center (Shanghai) from 2- 4 June. The event brings together the worlds of water technology and water management, aiming to present integrated solutions and holistic approaches to water challenges that Asia is facing.

Toroidal conductivity sensor in Clean-in-Place (CIP) System;What does CIP cleaning mean?How works of Toroidal conductivity sensor? Toroidal conductivity sensors consist of two toroidal coils inside an inert plastic case (these toroidal coils are how the “toroidal” sensor gets its name). One toroid emits an electric field, and the other detects a small induced electric current proportional to the number of ions present (this induced current is why toroidal sensors may also be called “inductive” sensors). The two toroids form a transformer whose coils are interconnected by the resistance of the surrounding electrolytic solution.In contrast to traditional contacting conductivity sensors,

Relationship between Oxygen,Temperature and Pressure in Air,and dissolved oxygen sensor is calibrated in air for slope.

Antigenic proteins in latex products can cause type I allergy. We investigated the effects of potassium hydroxide (KOH) solution on the allergenicity of proteins in natural latex sap and latex gloves by using an EAST competitive inhibition immunoassay and skin prick test. Latex sap was mixed with KOH solution at different concentrations and incubated over various periods of time at room temperature.The SJG-2083CS Online Potassium hydroxide(KOH) concentration Meter is a brand-new online smart digital acid and alkali concentration meter

The term “pH” is an abbreviation for the “potential of hydrogen.” pH is a unit of measurement which represents the concentration of hydrogen ions in a solution. This unit was introduced by biochemist Søren Peter Lauritz Sørensen in 1909. It was an easy way to represent the concentration of hydrogen ions in a solution during titrations. When an acid or base is added to water, that compound dissociates into ions. For acids one of those ions is a hydrogen ion (H+) and for bases one of the ions is a hydroxide ion (OH–). This description of acids and bases is known as the Arrhenius Theory. The concentration of hydrogen ions are often described by the pH scale as a numeric value.

ORP is a term used frequently in the water treatment and food processing industry. ORP stands for

New technologies also will dramatically reduce testing costs and generate millions of dollars of savings per wastewater plant based on chemical feeds and repurposing operational funds. All wastewater should be actively monitored to ensure it meets the specific safety requirements for any intended reuse. Monitoring should not just focus on the environmentals like pH, DO, TDS, TSS,Turbidity,COD,Ammonia,Total Nitrogen,Total phosphrous etc.; once treated, it should be tested for dangerous toxins like lead, copper, nitrates, arsenic, chlorine, dissolved oxygen, chromium and silica, as well as several organics and microbial parameters.

When chlorine is added to drinking water, it proceeds through a series of reactions described below. When chlorine is added to water, some of the chlorine reacts first with organic materials and metals in the water and is not available for disinfection (this is called the chlorine demand of the water). The remaining chlorine concentration after the chlorine demand is accounted for is called total chlorine. Total chlorine is further divided into: 1) the amount of chlorine that has reacted with nitrates and is unavailable for disinfection which is called combined chlorine and, 2) the free chlorine, which is the chlorine available to inactivate disease-causing organisms, and thus a measure to determine the potability of water.

Oxidation-reduction potential (ORP) measures the ability of a lake or river to cleanse itself or break down waste products, such as contaminants and dead plants and animals. When the ORP value is high, there is lots of oxygen present in the water. This means that bacteria that decompose dead tissue and contaminants can work more efficiently. In general, the higher the ORP value,
