Water Treatment TechnologyDissolved Oxygen: Why It Matters in Water and Wastewater Treatment
Dissolved oxygen is a parameter that matters differently depending on whether the context is drinking water, industrial process water, or biological wastewater treatment. Here is a general orientation.

ETPColor Removal from Textile Dyeing Effluent: Why It's Different from Standard ETP
Dye-bearing textile effluent presents a specific treatment challenge — visible color — that a standard ETP designed only for organic load and suspended solids does not automatically address. Here is a general orientation.

ETPWhen a Facility Needs Both an ETP and an STP
Some facilities generate both industrial process wastewater and ordinary domestic-type sewage, and these generally need to be treated separately. Here is how to think about that situation.
Read article→ETPETP Sludge Management: The Basics
Every effluent treatment plant produces sludge as a by-product, and managing it properly is as important as the treatment process itself. Here is a general orientation to what that involves.

Water Treatment TechnologyWTP vs ETP vs STP: Complete Comparison
WTP, ETP and STP are three distinct types of treatment plants that are sometimes confused with each other since all involve "treating water." Here is how they actually differ in purpose, input and output.

Tannery effluent is chemically different from most other industrial wastewater in Bangladesh — chromium, sulfide and very high organic and salt loads all need to be addressed together. Here is a general orientation to how that treatment train is usually approached.

Effluent discharge in Bangladesh is regulated by the Department of Environment (DoE) under the Environment Conservation Rules. This is a general orientation to how that compliance process typically works — not a substitute for advice from DoE or a qualified environmental consultant.
