  • An Easy Guide to Understanding Surfactants

    What is a Surfactant? Surfactants are a primary component of cleaning detergents. The word surfactant means surface active agent. As the name implies, surfactants stir up activity on the surface you are cleaning to help trap dirt and remove it from the surface. Surfactants have a hydrophobic (water-hating) tail and a hydrophilic (water-loving) head. The hydrophobic tail of each ...

  • Dual bioremediation of phenol and Cr(VI) by mixed microbial cultures in the presence of molasses

    Simultaneous phenol and Cr(VI) bioremoval by two different mixed cultures, from petroleum-contaminated soil (PS) and boron-contaminated wastewater (BW), was investigated in regard to different culture media, pH levels (6–8), initial phenol (25–100 mg/L) and Cr(VI) (15–50 mg/L) concentrations. The optimum medium was found to be mineral salt medium tested, which contained 1% (v/v) molasses ...

  • How To Complete A Soil Test The Right Way

    A soil test should be one of the first steps you take in your landscape plan. Many of us never take this important first step, which contributes, to wasted resources and wasted time. The U.S. Department of Agriculture says soil testing is an “essential” tool that provides information on fertility and pH. Testing also indicates ...

  • Defluoridation of groundwater using mixed Mukondeni clay soils

    Excess fluoride in drinking water is harmful to human health and therefore it needs to be removed from water before consumption. The potential of locally available mixed Mukondeni clay soils (MMCS) as a cheap adsorbent for the removal of fluoride from aqueous solution was investigated. Characterization of MMCS was done by X-ray fluorescence, X-ray diffraction, scanning electron microscopy, ...

  • An Introduction to Bioremediation and its Applications

    A variety of toxic chemicals, metals, and effluents are created and used in industrial processes. These elements need to be degraded to ensure that they do not harm the environment when disposed. A specialized process and equipment are required to perform this task. This is where bioremediation comes in. What is Bioremediation, and what are its Types? In simple ...

  • Comparative study on nutrient removal of agricultural non-point source pollution for three filter media filling schemes in eco-soil reactors

    Nutrients (nitrogen and phosphorus) from agricultural non-point source (NPS) pollution have been increasingly recognized as a major contributor to the deterioration of water quality in recent years. The purpose of this article is to investigate the discrepancies in interception of nutrients in agricultural NPS pollution for eco-soil reactors using different filling schemes. Parallel eco-soil ...

  • Case study - One-pass-trencher used to repair Tyler Dam

    Greg DeWind takes pride in his one-pass trenching machine. With a smile on his face, he watches Wednesday as it is used to dig a trench at the Lake Tyler Dam. The 225,000-pound, 3,000-horsepower machine mixes soil, cement and bentonite clay as it cuts a trench that is 2 1/2-foot wide and about 70 feet deep, according to Steve Richards, with ETTL Engineers and Consultants. It burns about 100 ...

  • Changes of toxic metals during biological stabilization and their potential ecological risk assessment

    With various disadvantages of pollution control technologies for toxic metal-contaminated soil, we mixed contaminated soil with sludge for in situ composting to stabilize toxic metals, so plants are enriched to take up the toxic metals. When simulating the above, we added toxic metal solution into sewage sludge, and then composed it with steel slag to determine inhibition of the availability ...

  • Remediation of phenanthrene contaminated soils by nonionic–anionic surfactant washing coupled with activated carbon adsorption

    Batch experiments were conducted to investigate the performance of nonionic–anionic mixed surfactants and their recovery through activated carbon. The solubilization capabilities of mixed surfactants toward phenanthrene (PHE) were reduced by addition of anionic surfactant to the mixed systems. Results showed that sorption of Triton X-100 (TX100) onto soil decreased with increasing mass ...

  • Vacuum systems for tall-oil applications

    Tall oil is a viscous oily liquid and considered one of the most important by-products of wood pulp manufacturing. Through a fractioning process crude tall oil can be turned into valuable fatty and resin acids. Vacuums play a key role in this procedure. An application in Finland currently proves that technology from Hanover-based Körting is ideally suited for this purpose. ...
