Stainless Steel Water Analyzer - 3ft Height, 1.5ft Length, 1ft Width | Measures Bod, Cod, Tss, Ph For Industrial Etp Water

Principle:
Many organic substances dissolved in water absorb ultraviolet light. Therefore, the total amount of organic pollutants in water can be measured by measuring the absorption of these organic substances by ultraviolet light at a wavelength of 254nm. MCOM700 series sensors use two light sources, one 254nm ultraviolet light and one 850nm infrared light, which can automatically compensate the optical path attenuation and turbidity effects, thus achieving more stable and reliable measurement values.

MEASUREMENT PRINCIPAL OF COD BOD TSS
MCOM700 UV254/COD sensor software (see modbus user manual for details) Provides
1- or 2-point COD calibration options in mg/L. KHP (potassium hydrogen phthalate,
C8H5KO4), CAS# 877-24-7, is a commonly used stain for environmental studies and can be used for COD calibration.
1. COD :- The chemical oxygen demand (COD) test is commonly used to indirectly measure the amount of organic compounds in water. Most applications of COD determine the amount of organic pollutants found in surface water (e.g. lakes and rivers) or wastewater, making COD a useful measure of water quality. It is expressed in milligrams per liter (mg/L), which indicates the mass of oxygen consumed per liter of solution.The basis for the COD test is that nearly all organic compounds can be fully oxidized to carbon dioxide with a strong oxidizing agent under acidic conditions. The amount of oxygen required to oxidize an organic compound to carbon dioxide, ammonia, and water denotes a COD value as shown by below equation:
2. BOD :- Biochemical oxygen demand (BOD) (also called biological oxygen demand) is the amount of dissolved oxygen needed (i. e., demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period. The BOD value is most commonly expressed in milligrams of oxygen consumed per litre of sample during 5 days of incubation at 20 Degree Celsius and is often used as a surrogate of the degree of organic pollution of water.BOD is similar in function to chemical oxygen demand (COD), in that both measure the amount of organic compounds in water. However, COD is less specific, since it measures everything that can be chemically oxidized, rather than just levels of biodegradable organic matter.
3. TSS :- Totalsuspended solids (TSS) are particles that are larger than 2 microns found in the water column. Anything smaller than 2 microns (average filter size) is considered a dissolved solid. Most suspended solids are made up of inorganic materials, though bacteria and algae can also contribute to the totalsolids concentration. These solids include anything drifting or floating in the water, from sediment, silt, and sand to plankton and algae. Organic
particles from decomposing materials can also contribute to the TSS concentration
