Chemical Oxygen Demand or COD is a measurement of the oxygen required to oxidize soluble and particulate organic matter in water. COD can be measured in real-time with our COD sensors to improve wastewater process control and plant efficiency.

Media Filters: Trickling Filters and Anaerobic Filters ...

Media filters are a sanitation technology that use microorganisms that are attached to a high surface area medium to primarily remove soluble organic matter (measured as BOD or COD) as wastewater passes through the medium. Trickling filters use aerobic processes for treatment while anaerobic filters operate under strict anaerobic conditions.

5 Ways to Reduce COD in wastewater | by Jopari Yusuf | Medium

How can I reduce the BOD and COD from a treated waste water?

They pass through any filter and keep the BOD & COD high. Using Physico-chemical treatment of wastewater, in which you try to separate colloidal particles, is achieved through the addition ...

Treatment Technologies for Organic Wastewater

The COD value is always measured by the acidic potassium permanganate method and potessium dichromate method, and could reflect the pollution degree of reducing matter in water, including ammonia and reducing sulfide, so in wastewater with high quantity of reducing matter, the COD value will overestimate the organic pollutants in the water.

BOC vs COD - environmentalleverage.com

Almost all wastewater treatment plants are required to measure one of these three items as a measure of the pollution value in the water. COD should always measure higher than TOC and then BOD. COD or Chemical Oxygen Demand is the total measurement of all chemicals in the water that can be oxidized.

Chemical Oxygen Demand (COD) Stormwater Treatment

Chemical oxygen demand (COD) is often used to measure organic matter in wastewater, treated effluent, and receiving waters. Although COD measures more than organic constituents, the organic fraction usually predominates and is the constituent of interest.
