  • Faecal sludge as a solid industrial fuel: a pilot-scale study

    Revenues from faecal sludge (FS) treatment end products could offset treatment costs and contribute to financially viable sanitation. In urban sub-Saharan Africa, energy-producing resource recovery has the potential to generate greater revenue than use as soil conditioner. In contrast with wastewater sludge, the technical feasibility of using dried FS as solid fuel in industries has not been ...

  • MSW Management: Safely Countering the Rise of Landfill Odors

    One of the core challenges of landfill and compost site management is fighting the rise of foul odors. In addition, as communities expand further out from previous areas, they eventually become neighbors to landfills – calling for a comprehensive odor-control approach to countering odor complaints. In fact, compared to other industrial applications such as wastewater treatment and asphalt ...

  • Geophysical applications to solid waste analysis

    Abstract: Case studies of regional landfills show that electromagnetic geophysical methods can accurately and inexpensively define boundaries and thickness of waste. Degradation of putrescible solid waste generates conductive leachate that can be imaged with a frequency-domain terrain conductivity meter. Terrain conductivity measurements can be modified through a simple algorithm based upon ...

  • Performance evaluation of 388 full-scale waste stabilization pond systems with seven different configurations

    Waste stabilization ponds (WSPs) and their variants are one the most widely used wastewater treatment systems in the world. However, the scarcity of systematic performance data from full-scale plants has led to challenges associated with their design. The objective of this research was to assess the performance of 388 full-scale WSP systems located in Brazil, Ecuador, Bolivia and the United ...

  • Adsorptive removal of As(III) from aqueous solution by waste litchi pericarps

    The present study investigated the removal of arsenite anions (AsO33−, referred to as As(III)) from aqueous solutions by waste litchi pericarps (LPs). Influential factors such as the adsorbent dose, contact time, solution pH, and initial As(III) concentration were investigated. The optimum conditions for As(III) adsorption by the LPs occurred at a contact time of 60 min, adsorbent dose ...

  • What is Zero Waste?

    Over the past five years or so, leading solid waste and recycling organizations, communities and businesses across the country have increasingly embraced Zero Waste. Zero Waste policies and programs establish practical ways to eliminate waste and safely reuse, recycle or compost discarded products and packaging. However, there has been confusion in the marketplace due to the many definitions of ...

  • Characterization of biochar prepared from slow pyrolysis of Jordanian olive oil processing solid waste and adsorption efficiency of Hg2+ ions in aqueous solutions

    Solid waste from Jordanian olive oil processing (OOSW) was used to prepare biochar samples by slow pyrolysis at terminal temperatures of 350, 450, 550 and 630 °C; henceforth known as BC-350, BC-450, BC-550 and BC-630, respectively. These samples were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction, ash content, moisture content and ...

  • How & Why We Measure Suspended Solids

    In case you weren’t sure, Suspended Solids is simply a density measurement used to describe exactly how much waste sludge and particles are in the water, and is measured in milligrams per litre (mg/l), grams per litre (g/l) or percentage solid (%). 1000mg/l = 1g/l = 0.1%. It is used to calculate the amount of material, or load, in a wastewater or industrial system. Suspended Solids ...

  • Q&A: OMI’s Dr. Laura Haupert Discusses Eco-Friendly Odor Solutions for Landfills

    The waste management arena is continually challenged when it comes to fighting odors, which often become a major nuance for neighbors. Landfills all throughout the U.S. also have to contend with finding the right odor-abatement solutions that are both effective, and safe for employees and surrounding communities. In the following “Clearing the Air” Q&A, we speak with Dr. Laura ...

  • Can’t Afford Pond Dredging? We have solutions.

    Ponds and lakes naturally accumulate sludge and nutrients that lead to eutrophication and eventually pond or lake death. Natural succession is driving all lakes and ponds to become meadows and eventually forest. To slow or reverse this process and maintain a lake or pond beneficial microbes are critical. These beneficial microbes improve water quality by reducing nutrients and sludge through ...

  • Evaluation of the energetic potential of sewage sludge by characterization of its organic composition

    The composition of sewage sludge and, thus, its energetic potential is influenced by wastewater and wastewater treatment processes. Higher or lower heating values (HHV or LHV) are decisive factors for the incineration/gasification/pyrolysis of sewage sludge. The HHV is analyzed with a bomb calorimeter and converted to the LHV. It is also possible to calculate the heating value via chemical ...
