  • Application of sediment quality guidelines in the assessment of mangrove surface sediment in mengkabong lagoon, sabah, Malaysia

    Mangrove sediments were extensively studied all around the world and act as sinks and sources of contaminants in aquatic systems because of their variable physical and chemical properties (Rainey et al., 2003; Marchand et al., 2006; Pekey, 2006; Karbassi et al., 2007). Trace metals can accumulate in the upper sediment. Such accumulation takes place by biological and geochemical mechanisms and can ...

  • Designing With Geosynthetic Clay Liners

    In construction, preventing the penetration of liquids and gases is essential to maintaining the integrity of a structure. Often, containment is just as important, especially when dealing with chemical contaminants or other waste. When looking to stop the spread of contaminated liquids and gases, there are few tools as effective as geosynthetic clay liners (GCL). Read on to learn how to design ...

  • Feasibility of a flow-through treatment regime by the EOH2O™ electrolytic oxidation process to meet BOD, TSS and ammonia discharge limits from municipal facultative wastewater lagoons

    The patented EOH2O electrolytic oxidation process has been employed as a continuous batch treatment system for reduction of nutrients, TSS, odor, and pathogens in manure lagoons for several years. Due to the positive results of such applications, several Pacific Coast rural municipalities approached Aquatic Technologies to determine if a constant flow-through treatment system could be designed to ...


  • Design of animal waste management strategies to achieve regional environmental objectives

    Anaerobic lagoons are currently used for swine waste management in many countries, worldwide. Recent initiatives, for example in North Carolina, USA, calling for their replacement have increased the need for characterisation of the cost and treatment effectiveness of each alternative. Identification of the most effective solution to achieve collective environmental targets needs an integrated ...

  • Alternative Project Delivery California`s First Design-Build-Own-Operate Biosolids Recycling Facility

    ABSTACTThe Sacramento Regional County Sanitation District (District) engaged the private sector for the design, finance, construction, ownership, and 20 year operation and of a Biosolids Recycling Facility (BRF). In early 2005, the BRF began processing solids into heat dried pellets to be beneficially reused. The BRF is located at the Sacramento Regional Wastewater ...

  • WWTP Sludge reduction case study

    Introduction The City of Spring Valley, IL was seeking bioaugmentation to reduce the economic burden of sludge dredging and disposal and to evaluate the possibility of restoring the microbiological activity in the lagoon. The lagoon was flooded several times from the near-by Illinois River, which created different strata of inorganic silt/organic sludge and densely packed sludge at the ...

  • Geotube Dewatering Technology Helps Manage Wastes From Power Generation - Case Study

    Power generation by-products such as fly ash and bottom ash can be a real challenge to remove and manage. But a simple technology allows facilities large and small to easily consolidate these materials—and make adjustments as needed based on volume. It's called Geotube dewatering technology, and it involves pumping sludge through a specially designed fabric container. The water filters ...

  • Improving GAC efficiency

    PROJECT BACKGROUND: A Superfund Site located in the Northeast US was previously used for reclaiming and re-refining waste oils from 1945-1985. A TSCA inspection uncovered the presence of PCB’s in several lagoons onsite. The site had seven lagoons containing over 9,000,000 gallons of water and oil. Due to heavy rains, the lagoons fill frequently. Therefore, several emergency removal actions were ...
