STAR (In Situ) Pilot Test to Treat Coal Tar and Creosote - Former Creosote Manufacturing Facility in Washington - Case Study
Overview The subject site is a 22-acre former creosote manufacturing facility in Washington. Coal tar and creosote contamination is present in the shallow alluvium unit to a maximum observed depth of 34 feet below ground surface (ft bgs) and is distributed in discontinuous layers separated by low permeability materials. A STAR Pre-Design Evaluation (PDE) (IMAGE 1) was conducted to evaluate Radius ...

Spatial distribution of PCDDs, PCDFs and dl-PCBs along the cascade of urban reservoirs
The river environment is a highly complex system with a variety of processes continuously changing along its continuum (River Continuum Concept). Therefore identification of the threats that result from different elements of the river ecosystem is an intricate task, mainly because of the transportation and biological, geological and chemical processes occurring in such a system. The overall ...

Rapid on‐site separation of as(III) and as(V) in waters using a disposable thiol‐modified sand cartridge
The rapid redox transformation of arsenic (As) species in waters presents a great environmental challenge in accurate determination of its concentration and toxicity. The motivation for our study is therefore to develop a method for rapid on‐site separation of As(V) and As(III) in various aqueous matrices. We synthesized a thiol‐modified sand (T‐sand), which selectively removed As(III) but did ...

Joint estimation of hydraulic conductivities of two sand samples in a W-tube system with a bi-exponential response
The motivation for this paper is the practical problem of interpreting bi-exponential rate-of-rise curves that are observed during many field piezometric tests. In the authors' previous study, a laboratory W-tube system of water flow through two samples of sand was introduced with an adequate mathematical model. The desired bi-exponential character of water flow was obtained by placing two ...

Determination of sand content in digestate
The biological treatment of separate collected waste becomes more and more important. The composting is still the dominant method of treating this waste, but the anaerobic alternative, the anaerobic digestion, plays an increasing part. In Germany already 15% of the whole capacity of biological treatment plants for separate collected biowaste are of anaerobic digestion (Kern, 1998), because of its ...

Petronas - production fluid desanding
Client: Petronas Tukau Field CETCO Oilfield Services Company has successfully implemented a technology to prevent sand issues which can potentially disrupt production in Petronas’ Tukau field near Miri in East Malaysia. Working with BJ Services, CETCO utilized a desanding system that extracts sand from the production fluids upstream of the field’s TKDP-A platform’s production facilities as ...

New Agent for Formation-Damage Mitigation in Heavy-Oil Reservoir: Mechanism and Application, China (SPE 112355) - Case Study
After the biological enzyme solution extracts crude oil from the sand surface, GreenZyme® can make oil and sand flow separately, preventing the formation of mud cakes while improving the mobility of crude heavy oil. Abstract Migration of formation fines has been shown to cause production decline in many wells, especially for sand production wells in heavy oil reservoir. Filter cakes in wire ...

Development of wet pre-treatment and pulper technology
Since 1984 BTA is involved in activities in the area of waste pre-treatment. This process was first implemented in 1986 in a pilot plant. The patented BTA-Process is consisting of the following main steps: - Wet pre-treatment of waste with separation of the contaminants and production of a pumpable suspension- Sand separation by a hydrodynamic grit removal system- Digestion of the suspension in ...

Why use stones with smaller particle sizes when formulating high-strength concrete?
As the coarse aggregate has an increased particle size, the bond with the cement paste is weakened, which increases the discontinuity of the internal structure of the concrete material, resulting in a decrease in the strength of the concrete.Coarse aggregates constrain the shrinkage of cement in concrete. Since the coarse aggregate and the cement paste have different elastic moduli, internal ...

Spragues’ Ready Mix deploys closed loop recycling equipment - Case Study
California’s Spragues’ Ready Mix (SRM) has deployed the first closed-loop recycling equipment combination of its kind: A concrete reclaimer separating fine and coarse aggregate, coupled with a slurry-recycling filter that dewaters cement fines to yield nearly ASTM C-94 grade batch water (less than 60 ppm). The company decided to purchase the Liebherr LRS 708 Concrete Reclaimer and ...

A key to hydric soil indicators
One of the biggest challenges new wetland delineators face is how to sort through all of the hydric soil indicators. There about 100 of them and it is easy to get lost. To help you manage this we have developed a key system that gets you to the right indicators by asking a few focused questions. To start, the user needs to understand how the indicators are arranged. They are grouped based ...

Membrane filter presses at Lower Fox River, USA - Case Study
Sustainable remediation Environmental remediation is always an ambitious task. And the case of the Lower Fox River remediation project in Wisconsin is no exception. To reduce risk to both human health and the environment, the project aims to remediate PCB-impacted sediments from a 21.4-km stretch of river through dredging, capping, sand separation, sediment dewatering, water treatment, and ...

Choosing the best shakeout technology for your process
In the modern foundry, there are many options when it comes to choosing the proper shakeout technology for your metal casting facility. Improper selection can lead to poor throughput, casting damage, and unnecessary down time, all which costs your foundry money. There are many di¬erent shakeout designs available on the market today, including brute force, variable drive, and two-mass ...

Dredging Short Courses
By Eric Lillberg, SRS Crisafulli Senior Applications Engineer When I first started as an applications engineer for SRS Crisafulli, I searched for information on the subject of dredging. I was surprised to find there was very little non-commercial content available. I have since found a pair of short courses, offered annually by Texas A&M, which I recommend highly to any professional ...

Whitepaper: Chemical-physical Water Treatment, Filtration and Flocculation
Introduction In water treatment plants chemical-physical processes play an essential part in the process chain. They are successfully employed in the pre- and post-treatment of waters of different origins, as well as of other process liquids. In this regard the removal of particles by filtration is a central step. Classical filtration processes are used for particles ranging from 1 μm to 100 ...
