  • Mining Waste, more than just camp waste - Case Study

    Mineral extraction adopts the very latest technology and operational methods and the waste aspect is a high agenda item that Inciner8 solves within mining compounds. Uncluttered, efficient operations with active heavy plant and machinery demand that waste solutions are present to clear, clean and deliver a consistent solution in many 24x7x365 mining operations. The onsite waste build-up ...

  • A comparative treatment of bleaching wastewater by physicochemical processes

    The bleaching effluent discharged from a pulp and paper mill contains chlorinated organic compounds which are toxic to living matter. Physicochemical treatments such as coagulation and different advanced oxidation processes (AOPs) were employed for combined bleaching effluent generated from the first two stages (i.e. chlorination and alkali extraction) (pH = 3.5, chemical oxygen demand (COD) = ...

  • Biosurfactant production by Mucor circinelloides on waste frying oil and possible uses in crude oil remediation

    Biosurfactants are biocompatible surface active agents which many microorganisms produce. This study investigated the production of biosurfactants by Mucor circinelloides. The effects of different factors on biosurfactant production, including carbon sources and concentrations, nitrogen sources, and iron (II) concentration, were studied and the optimum condition determined. Finally, the ...

  • Filter bed remediation - Case Study

    Biological filter beds usually consist of a mineral media over which effluent to be treated percolates. The media becomes host to a biomass which is grazed by a series of more complex organisms. If the growth of the biomass is greater than the rate at which the grazing occurs then the biomass film will accumulate in the bed. This will block the interstices of the media and restrict effluent ...

  • Cost saving reed bed refurbishment innovation - Case Study

    Greener Waste Technology has designed a reed bed remediation programme that avoids the need to remove media or replace reeds. The process is a hybrid scheme incorporating the modular sludge settlement chambers utilised in the Modular Reed Bed system and the existing asset which is already in place. This type of remediation saves on project timescales and reduces risk as well as cost. The ...

  • Is a Horizontal Remediation Well System Right for My Project?

    So your remediation project is moving towards a choice of remedy, whether it involves Dual Phase Extraction, Total Phase Extraction, Biosparging, Soil Vapor Extraction (SVE), Air Sparge (AS), or Chemox Delivery, or any combination of the above. Now, the concept of horizontal remediation wells (HRW’s) for your site seems intriguing. So what do you need to consider before proposing a ...

  • Enhanced Bio-Stimulation through Horizontal Wells

    Biosparging technology can be further enhanced when applied through Horizontal Remediation Wells. Since horizontal well systems typically have 4 to 10 times more screen footage in contact with the contaminated media than vertical systems, Horizontal Biosparge Wells can inject much greater volumes while maintaining the same low flow rates. This, in turn, leads to more rapid increases in dissolved ...

  • Chlorine Dioxide – dispelling the myths

    The internet is an incredibly useful research tool. It allows us to source and share information instantaneously. Unfortunately, this means that myths and misconceptions can spread very quickly and obscure the truth. In this post, we aim to tackle some of the myths that surround chlorine dioxide, and how this differs from our chlorine dioxide based product CleanOxide. Myth 1: Pure chlorine ...

  • The Power of 243 Vertical Wells

    This is a comparison of a Horizontal Remediation System and a Verticle Well System at a theoretical site with an area of 388,800 ft2   where with a Radius of Influence (ROI) of 20 feet, 12 Horizontal Remediation Wells, depending on plume geometry, can cover the same area as 243 vertical wells with the same ROI per well. Not only ...

  • N. Railroad Ave. Plume Superfund Site - New Mexico

    The NRAP site is a state-lead site in its 7th year of groundwater treatment operations by in-situ enhanced reductive dechlorination. The site’s lead agency, the New Mexico Environment Department (NMED), recently completed a response action report to document ongoing progress in their remediation efforts. NMED utilized EnviroInsite in that effort to assist in the interpretation of sampling ...

  • Horizontal Remediation Wells - Case Study

    Why wait 30 years…when HRWs are here today! After 30 years of remediation, the responsible party became frustrated with the limitations of vertical wells and the inability of methods used to achieve cleanup goals.  Seeking site closure, the soon to be client, turned to Directional Technologies and Horizontal Remediation Wells (HRWs) to break the stalemate.  The HRWs were ...

  • The best way to restore environments in the face of climate change

    Florida’s Kissimmee River once flowed freely. Fish, birds and other wildlife dwelled in the wetlands it fed. But in the 1960s, spurred by public outrage over flooding, the U.S. Army Corps of Engineers straightened the winding waterway and turned it into a drainage canal. Flip forward a few decades and the river is returning — at least in part. The U.S. Army Corps of Engineers has ...
