Clay county utility authority taps BCR to cut biosolids management costs - Case study
Clay County Utility Authority’s (CCUA) installed Neutralizer® systems at each of its four wastewater treatment plants (WWTPs) between 2006 and 2010. The streamlined, patented two-stage Neutralizer® system treats waste activated sludge and produces Class A residuals for unrestricted land application in just a matter of hours. Long-Term Success: 43% reduction in annual operating ...

Pyrobustor for the thermal treatment of biosolids
ARA Pustertal AG operates the Tobler wastewater treatment plant in South Tyrol, Italy. The Tobler ARA facility is the fi rst and only water treatment plant in Central Europe that is housed in an underground cavern. The impressive cavern plant, whose tunnels are twice as large as that of a highway tunnel, began operation in July, 1996. The inclusion of a sludge drying plant and a thermal sludge ...

Trends in biosolids handling technologies: economics and environmental factors
Changes in activated sludge technology, with a much greater focus on nutrient removal instead of removal of organics, together with relatively long sludge mean that the primary sludge stream has been lost, and the sludge produced is less degradable. At the same time with the growing importance of sustainable solutions, beneficial agricultural use is being increasingly used. This changes quality ...

Phosphorus runoff from wastewater treatment biosolids and poultry litter applied to agricultural soils
Received for publication March 19, 2009. Differences in the properties of organic phosphorus (P) sources, particularly those that undergo treatment to reduce soluble P, can affect soil P solubility and P transport in surface runoff. This 2-yr field study investigated soil P solubility and runoff P losses from two agricultural soils in the Mid-Atlantic region after land application of biosolids ...

Integration of thermal hydrolysis into sludge treatment at cottonvalley WwTW, milton keynes
The paper is a case study of the construction, commissioning and operation of a new 21,000 tonnes dry solids per annum sludge treatment centre at Anglian Water’s wastewater treatment works at Cottonvalley, Milton Keynes. The construction of the new sludge treatment centre was completed in summer 2008 and is part of Anglian Water’s £95 million AMP5 biosolids programme to provide treatment capacity ...

Screening system enables plant to increase treatment capacity - Case Study
Problem The activated sludge wastewater treatment plant in Kiel, Wis., treats high-strength wastewater from cheese production. When dissolved oxygen in the aeration basins dropped too low, the cheese waste influent was turned down or shut off. Operators wanted the plant to process more cheese waste, accept waste from septic haulers, increase biological treatment capacity, reduce biosolids costs, ...

Fluidized Bed Biosolids Disposal Gasification Case Study
Summary: In 2007, the Sanford, Florida, Utility Department sought to identify an onsite biosolids management and disposal system that could be integrated within their South Sanford Water Treatment Facility. The intended biogasification system would be a cost effective long–term solution, that is regulatory compliant and environmentally ...

Power to the Poo!
Discussing one’s use of the lavatory is usually frowned upon in polite conversation, however that is slowly changing. Experts in various fields of sustainable energy want you to be excited about using the “loo” for both the environment and your pocket book. Currently wastewater treatment plants consume large amounts of energy, between 1% to 3% of global output. Newer plants ...

Using Granular Sludge to Improve Digester Performance
Granular sludge technology compounds already impressive benefits of anaerobic digestion Anaerobic digestion is a robust process that transforms organic waste into valuable biogas for energy, as well as nourishing biosolids for agriculture. Applied in wastewater treatment, it also has the advantages of: Purifying even challenging, high-organic-load wastewater Lowering utility bills and ...

Responses to Internet misinformation
How do people figure out what is accurate and what is not? Science, involving diverse researchers reviewing data and repeating experiments, is the basis for understanding reality. Biosolids recycling has been the subject of such science. And we point to that science on our website, letting our readers decide. Recent Internet postings by Joseph Mercola, David Lewis, and others* - who imply ...

Municipal wastewater treatment plants as pathogen removal systems and as a contamination source of noroviruses and
Enterococcus faecalis Municipal wastewater treatment plants play a crucial role in reducing the microbial and pathogen load of human wastes before the end-products are discharged to surface waters (final effluent) or land spread (biosolids). This study investigated the occurrence frequency of noroviruses, Enterococcus faecalis and Enterococcus faecium in influent, final effluent and biosolids from four secondary ...

Determining potential indicators of
Cryptosporidium oocysts throughout the wastewater treatment processMost research on wastewater treatment efficiency compliance focuses on physicochemical and microbial indicators; however, very little emphasis has been placed so far on determining suitable indicator organisms to predict the discharge level of pathogens from treatment plants. In this study, raw wastewater, activated sludge, and the resulting final effluents and biosolids in four municipal ...

Predicting concentrations of trace organic compounds in municipal wastewater treatment plant sludge and biosolids using the PhATE™ model
This article presents the capability expansion of the PhATE™ (pharmaceutical assessment and transport evaluation) model to predict concentrations of trace organics in sludges and biosolids from municipal wastewater treatment plants (WWTPs). PhATE was originally developed as an empirical model to estimate potential concentrations of active pharmaceutical ingredients (APIs) in US surface and ...

Natchez Wastewater Treatment Facility Finds Success with New System
A popular magazine at the SRS Crisafulli offices is Treatment Plant Operator (TPO), which serves municipal water system operators. The November 2011 issue of TPO featured the Natchez, Mississippi Wastewater Treatment Facility in their Top Performer - Biosolids section, with an article titled "Sun Dried Success". "Natchez is the site of a new “greenhouse” solar biosolids drying ...

Wastewater treatment plant - ROPEC - deodorization plan project - Case Study
Bioconservacion has recently been awarded the supply of high capacity odor elimination media for two deodorization systems in a waste water treatment plant (WWTP) located in the Canadian capital of Ottawa. The Robert O. Pickard Environmental Centre (ROPEC) is located in the city's east end, right next to the Ottawa River. Using an extensive sewer system, all the wastewater coming from urban ...

Molecular Chemical Grinder Improves Digestion in Sludge
Municipal wastewater treatment plants (WWTPs) can reduce the costs and liabilities of sludge handling and disposal and increase their organic solids conversion rate with the Advanced Fluidized Composting (AFC) Process or the Advanced Fluidized Co-Digeson & Co-Generaon (AFC2) Process from BioConversion Soluons, LLC (BCS). The conventional sludge treatment techniques of aerobic and anaerobic ...
