In high-rate activated sludge (HRAS) systems, extracellular adsorption and intracellular storage have been referred to as the dominant mechanisms for capturing organic carbon from wastewater.

However, the quantification of storage products under short sludge retention time (SRT) of HRAS systems has rarely been studied until now. Since the measurement of storage products is complex and dependent on several variables, alternative solutions for substrate removal through storage are required to understand the high-rate...

Sustainability has become a word mentioned across our lives and the industry but isn’t as clearly defined as other terms like efficiency, safety factor or effluent quality.

According to the United Nations Brundtland Commission Report of 1987, “Sustainable development is…development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

Its lack of specificity can make...

Although an essential element for living cells, Phosphorus can have serious environmental effects when found in natural or engineering environments.

Major sources of Phosphorus pollution can come from wastewater effluent, commercial chemicals and agricultural waste. Phosphorus minerals, such as struvite and vivianite, can precipitate and form scales in drinking water and wastewater systems.

Although these minerals are problems when left uncontrolled and unmonitored, their recovery is beneficial.

With limited Phosphorus sources...
