  • Application of a flat surface ph electrode to demonstrate the effect of lime addition point relocation on mixing quality and ph decay of lime stabilized biosolids

     ABSTRACT Uniform lime incorporation into sewage sludge is critical for biosolids lime stabilization processes. There is no Class B biosolids regulation for lime incorporation. The slurry method is currently used to evaluate the pH of limed biosolids, but this method homogenizes the biosolids and potentially masks poor lime mixing. In this study, a flat surface pH electrode was used in ...

  • Energy from waste: the recycling of limed fleshings

    Leather products have been around a long while - there are those who claim that it is the second oldest business in the world. Going back a few millennia, when our earliest ancestors decided that sitting on hard rock was not a soft option, they turned to other materials in order to create more comfortable seating, as well as warmer bedding and improved clothing. Animal skins became the fabric ...

  • Continuously mixing one batch at a time

    Ready-mix company improves mixing efficiency and ingredient accuracy by switching to a rotary batch mixer. When a concrete and ready-mix producer moved to a new plant, the mixing process was redesigned to include batching for greater control over the final product 's ingredients. Rich-Mix Products makes concrete and ready-mix products and packages them for sale in home ...

  • Construction materials production. Application of the ABC-100 unit

    Expanded clay industry In the process of expanded clay production the argillous raw material homogenizes and mills in the drilling mud mixers and rollers. But these equipments not ensure qualitative desintegration. As result we obtain the expanded clay of low quality. Insufficiently desintegration and homogenizing of raw materials lead to the result when even 3% of carbonate ...

  • Bioremediation applied to high pH contaminated soil washing slurry

    BioFuture Ltd. in conjunction with General Smontaggi SpA have used applied environmental engineering and bioaugmentation to remediate hydrocarbon contaminated soil washing slurry. The soil washing slurry had been treated using lime to dry and stabilise it for transport to special landfill for disposal. The starting pH was 12.55 and it was successfully bioremediated so that it could be used as a ...

  • Pathogen Inactivation by a Closed Alakaline System

    ABSTRACTThe efficiency of advanced alkaline disinfection in closed systems has been demonstrated to depend on the balance of ammonia concentration, pH, exposure time, temperature, total solids content, post-treatment storage time and mixing effectiveness. When the alkaline system is a closed one, an additional pathogen stressor is added: pressure. The effect of the alkaline dosing has been ...

  • Solidification / Immobilisation of sludge from physical-chemical WWT process

    In 2003 econ received an inquiry from a service company operating an industrial waste water treatment plant. At the end of the physical-chemical WWT process this client generated metal-hydroxide sludge from his chamber filter presses. Originally he discharged the sludge into skips and brought it to a hazardous waste landfill. At this landfill, a solidification process was used to stabilise ...

  • Acid mine drainage treatment

    Acid mine/rock drainage is a rampant problem in the world today. The above photo depicts acid drainage at an abandoned mine in the Yukon Territory of northwest Canada. This mine shares a similar history to thousands of other mines throughout the world. It was in operation for six short years in the 1950’s, producing gold ore. Its profitability eventually failed and it was abandoned. In the ...

  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • Wastewater sterilization (purification): completely new method “vortex layer machine”

    The purification and safe disposal (neutralization) of industrial waste water effluents represent a very important ecological problem. The principal problem or requirement involves reducing the concentration of harmful impurities to concentration levels below their maximum allowable concentration limits. In fulfilling this requirement the amount of fresh water consumption needed to maintain the ...

  • Batch blenders make modern mortars in China

    With no internal moving parts, blenders minimize abrasive wear and simplify cleaning at two SureBlock plants. In 1997, US-based SureBlock entered a joint venture with China's Tianjin People's Building Material Products Factory to make concrete masonry units (CMUs). Commonly known as concrete blocks, CMUs come in many shapes, sizes, and colors. They are mainly used to erect structural walls, ...

  • Simple way to reduce costs and increase profit

    Packaged-food producers frequently use and then must discard large batches of cooking oil used in their process. Usually they drain most of the oil directly from equipment, but they must remove residual oil by regularly washing fryers, ovens, conveyors, and other machinery. The oil mixes with the wash water and becomes part of the plants wastewater stream. Having oil in wastewater complicates the ...

  • Land Treatment

    Introduction Land Treatment is a full-scale bioremediation technology in which contaminated soils, sediments, or sludges are turned over (i.e., tilled) and allowed to interact with the soil and climate at the site. The waste, soil, climate, and biological activity interact dynamically as a system to degrade, transform, and immobilize waste constitutes. Wastes are periodically tilled to aerate the ...
