COD (Chemical Oxygen Demand)
What is COD (Chemical Oxygen Demand)?
COD (Chemical Oxygen Demand) measures the amount of oxygen that would be needed to chemically oxidize organic and inorganic substances in water. In simple terms, it tells you how much pollution (organic matter, chemicals, or waste) is present in the water.
The higher the COD value, the more contaminants there are — indicating poorer water quality.
Why is COD important to test?
-
Pollution Detection: High COD levels often mean the water is polluted with organic waste (such as from sewage, industrial discharge, or decaying plants).
-
Health & Safety: Contaminated water with high COD may carry bacteria, viruses, or toxic substances that can be harmful if consumed or used.
-
Environmental Protection: For industries and environmental monitoring, testing COD helps ensure wastewater isn’t harming rivers, lakes, or groundwater.
-
Aquaculture & Gardening: Fish, plants, and crops are sensitive to water quality. High COD can damage ecosystems or reduce crop yields.
-
Quick Indicator: COD gives a fast snapshot of overall water cleanliness.
Why use a Water Quality Testing Pen for COD?
-
Portable & Fast: Instant readings on-site, no need for lab analysis.
-
Multiple Parameters: Get COD along with TDS, TOC, EC, temperature, and UV — a full water quality profile in one device.
-
Easy to Use: No complicated setup — just dip, press, and read.
TOC (Total Organic Carbon)
What is TOC (Total Organic Carbon)?
TOC (Total Organic Carbon) measures the total amount of carbon found in organic compounds in water. Organic carbon comes from sources like:
-
Decaying plant and animal matter
-
Industrial waste
-
Sewage or wastewater
-
Agricultural runoff (fertilizers, pesticides)
A higher TOC value means there is more organic contamination in the water.
Why is TOC important to test?
-
Water Purity Indicator: High TOC can signal the presence of pollutants that may affect taste, odor, or safety of drinking water.
-
Health Concerns: Organic contaminants can react with disinfectants (like chlorine) to form harmful byproducts (e.g. trihalomethanes).
-
Regulatory Compliance: Many industries (like pharmaceuticals, food production, and water treatment plants) monitor TOC to ensure water meets strict safety standards.
-
Environmental Monitoring: High TOC can harm aquatic life by reducing oxygen levels as organic material decomposes.
-
System Performance: In water treatment systems (like RO filters), monitoring TOC helps verify how effectively the system is removing organic contaminants.
TDS (Total Dissolved Solids)
What is TDS (Total Dissolved Solids)?
TDS (Total Dissolved Solids) measures the combined content of all inorganic and organic substances dissolved in water. These solids can include:
-
Minerals (calcium, magnesium, potassium, sodium)
-
Salts
-
Metals
-
Organic matter
TDS is expressed in parts per million (ppm) or milligrams per liter (mg/L).
Why is TDS important to test?
-
Water Taste & Quality: High TDS can affect the taste, appearance, and overall palatability of drinking water.
-
Health Monitoring: While some dissolved solids are harmless or even beneficial, very high levels may indicate harmful contamination from industrial waste, sewage, or agricultural runoff.
-
Appliance Protection: High TDS can cause scale buildup in water heaters, coffee machines, and RO filtration systems, reducing efficiency and lifespan.
-
Aquariums & Hydroponics: Sensitive aquatic life and plants require controlled TDS levels for optimal health.
-
Swimming Pools & Spas: TDS monitoring helps maintain water balance and clarity.

What is COD in tap water?
COD (Chemical Oxygen Demand) in tap water refers to the amount of oxygen required to oxidize organic and inorganic substances in the water. It is a key indicator of water pollution and water quality.
Where does COD in tap water come from?
COD in tap water can originate from various sources, including:
-
Natural Organic Matter
-
Decomposing plant materials, algae, and microbial activity in water sources.
-
-
Industrial Pollution
-
Wastewater discharge from factories, chemical plants, and manufacturing industries can introduce organic and inorganic pollutants.
-
-
Agricultural Runoff
-
Fertilizers, pesticides, and decaying plant materials can contribute to COD levels in water bodies.
-
-
Sewage and Wastewater
-
Domestic wastewater, sewage leaks, and improper waste disposal can introduce high COD levels.
-
-
Disinfection Byproducts
-
Chemicals used in water treatment, such as chlorine, may react with organic matter and contribute to COD.
-
-
Heavy Metals and Other Contaminants
-
Industrial waste or natural erosion can introduce heavy metals that contribute to COD levels.
-
High COD levels in tap water indicate a higher presence of organic pollutants and reduced water quality, which may require advanced filtration methods like reverse osmosis (RO) or activated carbon filtration to ensure safe drinking water.
What is TOC in tap water?
TOC (Total Organic Carbon) in tap water refers to the total amount of carbon found in organic compounds present in the water. It is a key indicator of water quality and potential contamination. High TOC levels may indicate the presence of pollutants, which can affect taste, odor, and overall water safety.

A high TDS level can affect water taste, safety, and potential health risks, depending on what substances are present.
Where does TDS in tap water come from?
-
Natural Mineral Deposits
-
Rocks and soil naturally release calcium, magnesium, potassium, and sodium into water sources.

-
-
Industrial Waste and Pollution
-
Factories and mining operations can release heavy metals, chemicals, and toxins into nearby water bodies.
-
Industrial wastewater may contain sulfates, chlorides, and other pollutants.
-
-
Seawater Intrusion (In Coastal Areas)
-
In regions near oceans, saltwater can mix with freshwater sources, increasing sodium and chloride levels in drinking water.
-
-
Household Contaminants
-
Soaps, detergents, and personal care products can introduce organic compounds into the water supply.
-
How to Reduce TDS in Tap Water?
-
Reverse Osmosis (RO) Filtration – Removes up to 99% of TDS, including contaminants and excess minerals.
-
Activated Carbon Filters – Reduce chlorine, organic compounds, and some dissolved substances.
-
Distillation – Heats water to remove dissolved solids through evaporation and condensation.
-
