Sizing of UASB (Upflow Anaerobic Pond) for Wastewater Treatment Plant

I think this is my first time I learnt about Upflow Anaerobic Sludge Blanket (UASB). I’ve ever learnt about anaerobic wastewater treatment, however I don’t have any idea about UASB and what the differences are. Since I am responsible as engineer in wastewater treatment package, I need to learn about UASB (there is a possibility that this system will be included in the package).

Wastewater Treatment System

A few weeks ago I got a discussion about wastewater treatment system in our proposed plant. I discussed with one of my colleague. He said, “Let the nature works! Let it process the wastewater by itself”. It sounds weird at the first time. But he’s right and he’s a bit wrong.

He’s right because the natural water in streams, rivers, lakes, and reservoir have a natural waste assimilative capacity to remove solids, organic matter, even toxic chemicals in wastewater. He’s a bit wrong because the process takes a really long time. That’s why we need wastewater treatment system to make it quick (read more in Water and Wastewater Calculation Manual). Read More

Design Criteria of Wastewater Treatment Plant

As already explained in previous post, design criteria is guideline values for designing new wastewater treatment facilities which is determined through research and laboratory scale model studies as well as operational experience. In this post I want to discuss more about the design criteria of wastewater treatment plant. It is important to note that the design calculations are usually based on certain assumptions. Hence, it is important  to have a clear understanding about the concept of design criteria and the significance in determining capacities and dimensions and wastewater treatment units. Read More

Design Philosophy of Wastewater Treatment Plant

After we discussed about water treatment plant, I want to share my new task about designing wastewater treatment plant. The explanation in this post will be quite simple and not really deep because I also still learn the fundamentals of designing water treatment plant. But after I discussed with one wastewater treatment plant vendor, I got more understanding about the plant and basic consideration in designing what equipment or process required in wastewater treatment plant.
