3 Soil Stabilization Techniques and when to Use Them
Each soil stabilization technique has its strengths and limitations. The type of project you're working on will often dictate the best choice for a soil stabilization method. This article will discuss three strategies: chemical stabilization, polymer stabilization, and mechanical stabilization. We'll also dive into when each method is typically used on a construction project. Chemical ...

Discover 3 Top Treatments For the Chemical Stabilization of Soil
Chemical stabilization of soilimproves the strength parameters of soil and increases its bearing capacity in road construction. New techniques in this process help companies prevent the costly problems of soil erosion. What Is the Chemical Stabilization of Soil? Simply put, chemical stabilization of soil involves adding chemicals to the soil to change the soil structure. This process helps ...

Road Dust Supression
Dust control is crucial in many industries and sectors including transportation, parking lots, mining, gas and oil, military, construction, and more. Suppressing dust on unpaved roads specifically is extremely important to the safety of an area. Dust control actions apply to any site where there is the potential for air and water pollution from dust traveling across the site or through ...

Why Soil Stabilization of Gravel Roads is Important
It's estimated that there are over 4 million miles of unpaved roads in the US. Not only do these roads lead to fast wear and tear of car tires, but they also pose an environmental risk due to the amount of dust they emit in the air. It's crucial therefore to introduce control measures that address both of these concerns. While spraying water, and using gravel as a cover remains the most popular ...

Microplastics Found in Human GI Tracts
In small study, plastic particles were found in bodies of all participants A recent study may have been small, but its results came as a big surprise to some. Lead author Dr. Phillip Schwabi of the Medical University of Vienna and Dr. Bettina Liebermann of Environment Agency Austria found microplastics particles in the GI tracts of every human participant in the study, which the researchers ...

Road Construction Using Soil Stabilization Techniques
Road construction using soil stabilization. No need for lime stabilization, lime-treated soil, or cement soil stabilization. Dirt is probably the cheapest and simplest construction material out there, but it’s not very strong compared to other choices. The spreading of lime, mixing of lime and soil with a rotary mixer, compaction of lime treated soil is NOT necessary! K31-APS super ...

Study: Anaerobic Digestion Reduces Microplastics in Sludge
Microplastics, including the microbeads found in many cosmetics and household products, are an increasing source of water pollution. Anaerobic digestion can help remove microplastics — a large cause of water pollution — during the sewage treatment process Microplastics, or tiny fragments of plastic, include microbeads, the plastic pellets present in thousands of household and ...

Anaerobic Digestion Reduces Microplastics in Sludge
Anaerobic digestion can help remove microplastics — a large cause of water pollution — during the sewage treatment process Microplastics, or tiny fragments of plastic, include microbeads, the plastic pellets present in thousands of household and personal care products, including toothpaste, cosmetics, and beauty scrubs. They also include fragments from the breakdown of anything in ...

Effect of lime addition during sewage sludge treatment on characteristics of resulting SSA when it is used in cementitious materials
Final disposal of sewage sludge is important not only in terms of satisfying the regulations, but the aspect of choosing the optimal wastewater treatment technology, including the sludge treatment. In most EU countries, significant amounts of stabilized and dewatered sludge are incinerated, and sewage sludge ash (SSA) is generated as a by product. At the same time, lime is one of the commonly ...

Solar disinfection and lime stabilization processes for reduction of pathogenic bacteria in sewage effluents and biosolids for agricultural purposes in Yemen
Yemen is the least advanced country among Middle Eastern countries in sewage reuse and safety control. The current sewage effluent quality in Yemen is generally poor as none of the existing sewage treatment plants produces effluents that comply with the effluent quality regulations. There is no plan to build tertiary treatment systems. However, the oxidation and stabilization ponds are ...

Lime stabilization of Septage - San Fernando, La Union
In mid-2008, engineers and staff from the San Fernando City health, planning, environment and engineering offices engaged in the first stage of a pilot demonstration project to determine the effectiveness of lime stabilization as a method of treating domestic septage in the Philippines. The Department of Health in the Philippines (DOH) also recognizes that lime stabilization is a viable ...

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 ...

Phosphorus runoff from wastewater treatment biosolids and poultry litter applied to agricultural soils
Received for publication March 19, 2009. Differences in the properties of organic phosphorus (P) sources, particularly those that undergo treatment to reduce soluble P, can affect soil P solubility and P transport in surface runoff. This 2-yr field study investigated soil P solubility and runoff P losses from two agricultural soils in the Mid-Atlantic region after land application of biosolids ...

Biogeochemical response of a northeastern forest ecosystem to biosolids amendments
Received for publication September 22, 2007. In the northeastern United States interest in the use of biosolids on forest lands is growing due to the prevalence of extensive forests and market incentives for waste disposal, yet much of the regulatory framework for biosolids land application is based on agronomic practice. This study evaluated the response of soils in a young (~20 yr old) ...

High efficiency odour control for wastewater treatment
Since the banning of sewage sludge disposal at sea in 1998 secondary treatment of sludge is now a vital part of waste water treatment. Initially many water companies opted for incineration, but over the last 10 years other options have been adopted such as producing stabilised sludge and pelletised dried sludge for use as fertiliser for agriculture. Currently over 62% of sludge is used in ...

Testing Techniques for Evaluating the Shear Strength of Lime/Fly Ash Slurry Stabilized Soil
Lime slurry pressure injections have been successfully used to stabilize and control swelling and expansive soils and low-strength clay soils to depths of up to 40 ft (12 m). When the activity of soils is somewhat lower, or when soils have large void ratios, lime/fly ash (L/FA) slurry mixtures have been injected to fill voids. It has been postulated that this action creates stronger seams, helps ...

Assessment of the Unconfined Compressive Strength of a Lime Stabilized Soil by an Abrasion Test
Stabilization by lime, which is frequently carried out to improve the mechanical properties of soils, results from the formation and development of cementitious calcium silicate aluminate hydrate gel. The gel produces interlocking and bonding of the soil particles, hence increasing the strength and abrasion resistance. The proposed method to assess the compressive strength of the existing ...
