Trash removal methods for improved mechanical emptying of pit latrines using a screw auger
Trash in pit latrines is one of the largest challenges facing pit emptying technologies, including the powered auger (the Excrevator), developed for improved emptying in lower- and lower-middle income countries. This study focused on two trash removal methods in conjunction with pit emptying by the Excrevator: (1) simultaneous removal of trash with sludge and (2) manual trash removal prior to ...

Comparing Sludge Removal Systems For Water Treatment Plants
Due to limited clearance and accessibility, effective removal of settled sludge beneath tube settlers has long been a challenge for plant owners and design engineers. They needed a sludge removal solution with a low-profile design that would offer flexibility during operation and maintenance. In 2012, Brentwood introduced a new sludge removal system to fill those needs - SedVac. To prove ...

Headmax® Suction head clarifier For Parkesstp - Case study
Parkes is located in central NSW and is famous for the Parkes Radio Telescope. Recently a new sewage treatment plant was constructed by John Holland and part of the process included a tertiary clarification process. Hydroflux Epco supplied a 15M HeadMax® Suction Head Clarifier. An EdiGate® energy dispersing inlet was provided as part of the package. Sludge is hydraulically transferred ...

ITI Technologies Introduces HWR47
ITI has cracked the code and has released HWR47 that will reduce sludge levels, odor levels and ammonia levels in an organic solution. This product was developed to address the multiple fines and costs associated with hog lagoons around the country. We believe this is a game changer in the industry and can dramatically reduce the costs associated with sludge removal and fines for odors. Our tests ...

Harlem, MT USA WWTP Uses FLUMP - 2013-case study
Excessive lagoon sludge accumulation contributes to the poor performance of any treatment system. Removing sludge from lagoon cells improves treatment and addresses violations in the Department of Environmental Quality enforcement action. The City of Harlem, Montana has a three cell partially mixed aerated lagoon system constructed in 1985. The lagoon system discharges to the Milk River. ...

Ammonium removal by native microbes and activated sludge within the Jialu River basin and the associated microbial community structures
To explore the availability of native microbes and activated sludge for ammonium removal, the native microbes and activated sludge in Jialu River basin were investigated in terms of ammonium-removing activities and their microbial communities using spectrophotometry and high-throughput sequencing. NH4+-N and total nitrogen (TN) in the targeted river ranged from 2.45 ± 1.76 to 8.56 ± 2.54 mg/L ...

Training: How to Remove Lagoon Sludge and Improve WWTP Outcomes
What should you do when your town is under multiple and ongoing consent orders for violations of its Montana Pollutant Discharge Elimination System (MPDES) wastewater discharge permit? Excessive lagoon sludge accumulation contributes to the poor performance of any treatment system, particularly in winter. Removing sludge from the lagoon cells will improve treatment at the facility and help to ...

Bioleaching in batch tests for improving sludge dewaterability and metal removal using Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans after cold acclimation
Bioleaching is a promising technology for removal of metals from sludge and improvement of its dewaterability. Most of the previous studies of bioleaching were focused on removal of metals; bioleaching in cold environments has not been studied extensively. In this study, Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans were acclimated at 15 °C and co-inoculated to explore the ...

Sludge drying beds, Sarasota County, Florida - Case Study
Dewatering sludge at wastewater treatment plants has traditionally been a major operational concern. Most large operations must use mechanical filter presses or centrifuges to efficiently dewater their sludge. For many smaller operations, however, this equipment is too expensive and too large for their needs. Therefore, many smaller facilities rely on the sand filter drying beds for sludge ...

Effect of Na2CO3 on the pretreatment of oily sludge using wet air oxidation
In this study, pretreatment of oily sludge, was carried out by Wet Air Oxidation (WAO) process. Experiments were conducted to see the effects of temperature, the initial COD, residence time, concentration of catalyst and OE (O2 excess) on the oxidation of the oily sludge. The results showed that in the WAO 88.4% Chemical Oxygen Demand (COD) was achieved after 9min. COD removal was 92.7% in the ...

Effects of CeO2 nanoparticles on system performance and bacterial community dynamics in a sequencing batch reactor
The effects of CeO2 nanoparticles (NPs) on the system performance and the bacterial community dynamics in a sequencing batch reactor (SBR) were investigated, along with the fate and removal of CeO2 NPs within the SBR. Significant impact was observed on nitrification; NH4+-N removal efficiency decreased from almost 100% to around 70% after 6 days of continuous exposure to 1.0 mg/L of CeO2 NPs, ...

Biodegradation and toxicity of melamine at high activated sludge concentrations in a membrane bioreactor
Melamine is recalcitrant and toxic to bacteria in conventional activated sludge systems. In this study, we investigated the degradation and toxicity of melamine in a membrane bioreactor (MBR) system operated at high activated sludge concentrations (∼8.5 g TSS/L). Melamine was dosed at 3 mg/L for about 100 days. The average melamine removal efficiency in the MBR system was 20 ± 11%. Meanwhile, ...

Nutrient removal, microbial community and sludge settlement in anaerobic/aerobic sequencing batch reactors without enhanced biological phosphorus removal
Nutrient removal, microbial community and sludge settlement were examined in two 3-litre laboratory-scale anaerobic/aerobic sequencing batch reactors (SBRs). One SBR was operated at 10°C and the other SBR at 20°C. Different from conventional enhanced biological phosphorus removal, most of the soluble sodium acetate was removed in the aerobic phase and no organic carbon uptake or biological ...
