Common drilling procedures for oil and gas, used widely around the world, produce a consistently increasing amount drill cuttings containing oil. In some cases, drill cuttings even contain other hazardous components such as mercury or NORM (Natural occurring Radioactive Material), requiring special attention. Treatment of drill cuttings is therefore beneficial from both an environmental and an economic standpoint, allowing valuable drilling oil to be recovered, and ensuring environmentally sound disposal of the...
The contamination of soils as a result of prior chemical production can often be unpredictable and diverse. The majority of such pollutants will require an ex-situ treatment method. Many of our VacuDry units can be used for direct-feeding contaminated soils. To reduce the input amount for thermal treatment, the VacuDry units can also be used in combination with soil-washing plants: In this case, customers only feed the high polluted fractions and screened fines (e.g. below 10 mm), as well as the filter-cake from...
Contaminated soil and building-rubble can be efficiently treated with VacuDry technology, including a diverse range of toxic and hazardous substances. VacuDry units also have low emissions and low power consumption, making on-site treatment with our mobile units both economically and environmentally sound.
The remediation division of Anguil Environmental Systems (formerly known as Global Technologies) is focused on treating emissions and water contaminants extracted from below the earths` surface. Formed shortly after the 1990 Clean Air Act targeted emissions associated with the extraction of polluted compounds from contaminated sites, Global subsurface remediation equipment has been successfully applied on contaminated sites in North and South America, Europe, Asia and Australia.
Measuring groundwater level or depth-to-water is critically important for identifying long term trends, including declining water levels, saltwater intrusion, seasonal variations, aquifer recharge, artificial aquifer storage and recovery, and level status for drinking water. Receiving groundwater data via remote data transmission from one of the many OTT telemetry options available saves time and resources spent in the field.
In infrastructure projects in which space has to be saved or land acquisition minimized, TenCate Geosynthetic soil reinforcement technology has been used in the design and construction of steep slopes or walls. The use of this technology increases the stability of such structures.
TenCate Geotube technology provides cost-effective and efficient dewatering and containment in the mining and mineral processing industry. In mining and mineral processing (mine tailings, coal sludge, etc), TenCate Geotube dewatering technology enables the recovery of valuable materials, provides structural stability, improves water quality, or reduces storage footprint by sometimes 50 to 80%. Conditioners or polymers are normally used to promote flocculation to improve dewatering rates, solids retention,...
Quicker, easier, safer transportation means are required. Depending on geographical zones, tunnels can be a must to reach your final destination easily. Decades of experience in tunnel constructions with TenCate Polyfelt P have shown that protection geotextiles replaces the need for drainage material around the tunnel lining.
The presence of uranium in water causes radiological pollution as all uranium radionuclides decay by both alpha and gamma emissions. Chemical aspects of uranium toxicity include mainly nephritis and other renal diseases. Mentioned harmful features affect on humans even in low concentrations thus requiring sensitive analysis methods.
WesTech designs and manufactures thickeners for the coal prep industry for product concentration, tailings disposal and CCD circuit washing, including HiFlo Thickeners and Deep Bed Paste Thickeners. Paste thickening is a proven technology increasing the profitability of mining operations. In the coal preparation plant there are two applications for paste thickening: concentrating fine coal and producing paste from coal tailings for increased water recovery and elimination of tailings ponding. Paste thickeners...
Analysis of soils and bottom sediments for mercury content is one of the most common analyses in the monitoring of environmental pollution. Background mercury concentrations in these objects are 10–100 μg/kg and in the polluted areas they exceed 10,000 μg/kg.
Today, many man-made structures using steel face harsh futures from the ravages of their natural enemy-corrosion. The cost of corrosion has proven to be almost incalculable as it shortens the life of almost any structure using steel. De Nora’s cathodic protection anodes, marketed under the trade names of LIDA and ELGARD, provide customers with a solution to this problem.
TenCate Geosynthetics deliver solutions that enhance the performance and design life of transportation engineering structures for paving. From our complete product line for Roadway and Railway Construction System Solutions, we offer materials that function for sealing, stress relief, adhesive bonding, and soil reinforcement. They offer robust mechanical properties coupled with high water flow capabilities that extend pavement life by retarding reflective cracking, waterproofing and reinforcing asphalt pavements.
Historically, landfills have been the most common method of organized waste disposal and remain so in many places around the world. Landfills are essential applications to ensure long service life and prevent soil pollution. In industrial basins, TenCate protection geotextiles guarantee the protection of the geomembrane against all risks of mechanical damages. A cost effective and environmental friendly solution to sort, treat and recycle waste.
Geosynthetics offer cost-effective, long-term solutions where conditions impose severe restrictions on road construction - where subsoils are poorly drained, or where the subgrade consists of cohesive, saturated and/or organic soil. Geosynthetics have also radically changed the way embankments, retaining walls, steep slopes, and even tunnels and bridges are constructed.
Through the application of modern mining technologies, WesTech helps to assure that the byproducts of minerals extraction process are made inert, reliably contained and kept from causing environmental damage. Implementation of WesTech tailings processing technology assures protection of the groundwater, surface waters, wildlife and communities which in the past have been the victims of tailings dam leaks and levy failures.
