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...

In the same way a physician meticulously performs open-heart surgery, cities have to modify their water system while it’s still running. But with flexible design and careful attention during construction, the transition to a new “heart” can go seamlessly without disruption of service.

A condition assessment showed the City of Lubbock needed to replace their 61- year-old Pump Station No. 7...

Scientists are predicting the Gulf of Mexico’s hypoxic zone to be the size of Massachusetts and close to the record from two years ago.

The hypoxic zone or “dead zone,” which is an area of low to no oxygen that can kill marine life, is forecast by National Oceanic Atmospheric Administration scientists to be approximately 7,829 square miles, close to 2017’s record size of...
