Neutralization and Biotreatment Process at Pueblo Plant Explained. Published: July 6, The Pueblo Chemical Agent-Destruction Pilot Plant’s Brine Reduction System, the last step of the Biotreatment Process, recovers water from biosludge producing a salt cake. The water is then recycled back into the plant.
Combination of Fenton processes and biotreatment
In leather wastewater treatment, the Fenton process followed by biotreatment (T. ferrooxidans) system made the removal rates of COD, BOD and chromium reached to 93%, 98%, and 100%, respectively (Mandal et al., 2010). Other applications of Fenton processes followed by biotreatment to treat different wastewater are listed in Table 2.
The Pueblo Chemical Agent-Destruction Pilot Plant, known as PCAPP, is safely and efficiently destroying a stockpile of chemical weapons currently stored at the U.S. Army Pueblo Chemical Depot (PCD). A two-step technology – neutralization followed by biotreatment – is the process selected to destroy the chemical agent stored at PCD.
Aeration Airflow at Wastewater Treatment Plants
At wastewater treatment facilities, aeration is used to introduce air into the wastewater to create an environment that promotes the growth of microorganisms to decompose the organic waste. The oxygen feeds or nourishes microorganisms within the basin, so the bacteria thrive and consume suspended particulates.
Increasingly stringent environmental regulations and industry adoption of waste minimization guidelines have thus, stimulated the need for the development of recycling and reuse options for metal related waste. This book, therefore, gives an overview of the waste generation, recycle and reuse along the mining, beneficiation, extraction, manufacturing and post-consumer value chain.

A household or business not served by a municipal treatment plant may have an individual septic tank, which treats the wastewater on site and discharges into the soil. Alternatively, domestic wastewater may be sent to a nearby privately owned treatment system (e.g. in a rural community).

- Why is anionic polyacrylamide chosen?
- Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
- How is an anionic polyacrylamide flocculant synthesized?
- In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
- What is anionic polyacrylamide (Apam)?
- 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
- What is high molecular weight polyacrylamide (PAM)?
- Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
