River and Stream Flow Measurement Formula

River and Stream Flow (Discharge) measurement is very important to provide the basic data required for river or stream water quality. The total discharge for a stream can be estimated by float method with wind
and other surface effects, by die study, or by actual subsection flow measurement, depending on cost,
time, man-power, local conditions and so on. The discharge [....]

Adsorption Process Bench Study

The packed bed of adsorbent can be regenerated. If the organic material is volatile, the carbon bed may be regenerated by steaming. However, it is more conven-tional to remove the carbon and reprocess the material through a furnace.In large installations, the furnace is installed as part of the carbon installation; in smaller installations, the carbon may be discarded, or removed [....]

How to Calculate Aeration Tank Air Quantity?

This example in connection with our previous post,

How to calculate Aeration Tank Volume?


Total BOD to be removed (Influent) = 250 mg/l (assume) x 1400  = 350 kg/Day (we consider 1400 M3/Day Effluent Plant)

Hence O2 to be transferred =350 kg/Day

Method of Aeration = Fine Bubble Diffuser

Biochemical oxygen demand. Measures the ability of common bacteria to digest organic matter, usually in a 5-day incubation at 2O


Relationship Between TS, TSS and TDS

Relationship between TS,TSS and TDS

These three solids tests can be related with Equation :TS = TSS +TDS

Total Solids. For regulatory and treatment purposes, total solids (TS) can first be classified as
suspended or dissolved. Total solids, as defined by Standard Methods and EPA, is the material
residue left in a vessel after evaporation of a sample and [....]

Differentiate between settleable and floatable solids |Types of Solids

Types of Solids:

                      The most basic solids differentiation is between settleable and floatable solids. An additional important differentiation is between volatile and non-volatile solids. A chemical or biological solid can potentially be removed from a wastewater by conversion through biological or chemical activity or incineration if the solid is organic and volatile (burnable at around 550°C). A volatile [....]
