The City of Houston (COH) is the fourth largest city in the nation. Houston Water (HW) within the Houston Public Works (HPW) department of the COH operates and maintains a large water and wastewater system. Its wastewater system includes 39 Wastewater Treatment Plants (WWTP) with a combined...

Siemann said the Rice study was made possible by the participation of the Houston Department of Public Works and Engineering, which helped Rice’s research team set up a test involving 12 open-topped 600-gallon tanks at one of the city’s satellite wastewater treatment plants in July 2013. ...
“A part of what we’re doing is looking into expansion of the plants and planning our available electricity and energy efficiency upgrades based upon a full study of current conditions at every single plant.” Recently, teams started monitoring several systems including those at its Houston Creek...
treatment plants (WWTPs) 3,8 . 83 84 More than 300 km 3 of wastewater is produced globally each year 9 . This volume equals one 85 seventh of the global river volume 10 . About 60% of this wastewater is treated prior to release, 86 ...
We have been very encouraged so far by the results we have observed at our various types of wastewater treatment plants (WWTP) in New Mexico and in California, in terms of reduced odor and biosolids as well as improved operations and realized savings. Improved processes such as these help us...
Microorganisms in wastewater treatment plants (WWTPs) are essential for water purification to protect public and environmental health. However, the diversity of microorganisms and the factors that control it are poorly understood. Using a systematic global-sampling effort, we analysed the 16S ribosomal ...
Biofilters are popular as an alternative method for treatment of volatile air pollutants like hydrogen sulphide originating from wastewater treatment plants. Despite several advantages over conventional chemical systems, one of the concerns of biological treatment of hydrogen sulphide is the production of la...
For example, during Hurricane Harvey in 2017, 18 of Houston’s 39 wastewater treatment facilities were submerged in floodwater and 30% of the city’s sewage collection system was under water for a week. Some 15% of treatment plants are at or have exceeded capacity. Many of these are also...
The adoption of automation for wastewater treatment plants has been a slow process for several reasons. One of the main obstacles has been the inability to measure important operating parameters at a sufficient frequency to use in feedback control. Dissolved oxygen and pH were the ...
