Biosolids- Considering the Types, Applications and Biosolids Drying Methods
While some water treatment plants are meant to simply make the sludge safe enough to dispose of, most facilities continue to treat the sludge so that the material can be put to good use in their communities. Once sludge is treated and processed to meet EPA safety standards for productive use, the resulting nutrient-rich organic material is termed as biosolids. Continue reading the full ...

Springfield - Case Study
At Their Disposal Komline-Sanderson minimizes solid waste disposal costs in Springfield, Mass The City of Springfield, Mass., currently uses a contract composting facility, which is located at the 65 MGD Bondi Island Wastewater Treatment Plant to dispose of their solid waste. The composting facility requires a feed of 40–45% solid materials to effectively operate the composting process. ...

Influence of water treatment residuals on dewaterability of wastewater biosolids
Co-dewatering of water treatment residuals (WTR) and wastewater biosolids can potentially benefit municipalities by reducing processing equipment and costs. This study investigated dewaterability (using capillary suction time, CST) of combined alum residuals (Al-WTR) and anaerobically digested biosolids at various blending ratios (BR), defined as the mass ratio of WTR to biosolids on a dry ...

Soil carbon sequestration resulting from long-term application of biosolids for land reclamation
Investigations on the impact of application of biosolids for land reclamation on C sequestration in soil were conducted at Fulton County, Illinois, where 41 fields (3.6–66 ha) received biosolids at a cumulative loading rate from 455 to 1654 dry Mg ha–1 for 8 to 23 yr in rotation from 1972 to 2004. The fields were cropped with corn, wheat, and sorghum and also with soybean and grass or fallowed. ...

‘SolarMix’ - Innovation in Drying Technology
Abstract The dramatic population increase in South East Queensland has seen a significant increase in the load placed upon our Sewage Treatment Plants (STPs) and a dramatic increase in the amount of biosolids produced at these STPs. Dewatered biosolids produced by most Water Authorities consists of 85 % water and only 15% solids and it is difficult to achieve a higher solids content with ...

Fate of biosolids trace metals in a dryland wheat agroecosystem
Biosolids land application for beneficial reuse applies varying amounts of trace metals to soils. Measuring plant-available or total soil metals is typically performed to ensure environmental protection, but these techniques do not quantify which soil phases play important roles in terms of metal release or attenuation. This study assessed the distribution of Cd, Cr, Cu, Mo, Ni, Pb, and Zn ...

Some unique solutions to water, wastewater challenges
Challenges are not unique to water and wastewater treatment, but the challenges thrown at operators and managers often require equal parts of thoughtfulness and creativity, with dashes of patience and persistence. This is why the industries are “home to some of the most ingenious professionals to be found in any industry,” according to an editorial in Treatment Plant Operator. ...

Three years of operation of North America's first nutrient recovery facility
The first full-scale nutrient recovery installation in North America became operational in May 2009 at the Clean Water Service's Durham Advanced Wastewater Treatment Plant in Tigard, Oregon. Recovering ammonia and phosphorus from the dewatering side stream as struvite has a positive impact on plant operations. Significantly reducing the phosphorus recycle lowers the phosphorus loading on ...

Removal of pharmaceuticals and personal care products in a membrane bioreactor wastewater treatment plant
Ninety-nine pharmaceuticals and personal care products (PPCPs) were analyzed in influent, final effluent, and biosolids samples from a wastewater treatment plant employing a membrane bioreactor (MBR). High concentrations in influent were found for acetaminophen, caffeine, metformin, 2-hydroxy-ibuprofen, paraxanthine, ibuprofen, and naproxen (104–105 ng/L). Final effluents contained ...

Operating experience of Aberdeen CAMBI thermal hydrolysis plant 2002
Introduction This paper reviews the establishment of a new 50 dry tonne per day biosolids processing facility at a green field site at Nigg Bay, Aberdeen Scotland. Prior to 2001 all sewage had been pumped by long sea outfall into the North Sea. Consequently there was only a minor biosolids operation in the area dealing only with small, rural works. Proposals were sought from a number of ...
