Posi-Shell Coatings

by LSC Environmental Products, LLC     based in Apalachin, NEW YORK (USA)

Posi-Shell erosion control coatings are the perfect low-cost solution to protect and stabilize slopes. Our long-term coatings are spray-applied and allow engineers or operators to protect acres (hectares) of slope in a single day. The finished coating is durable and textured, reducing water energy across large areas. The final product eliminates erosion, siltation, and (as a result) expensive rework. The product can be designed to last for years and is easily tracked into slopes when intermediate protection is no longer necessary. Indeed, when integrated, Posi-Shell actually improves soil quality by conditioning it for future seeding. Posi-Shell’s simplicity and durability make it tremendously effective at controlling windblown dust, infiltration, or runoff associated with clean or contaminated stockpiles. Unlike cumbersome tarps or geo-membranes, Posi-Shell erosion control coatings are spray applied and do not require any ballast. Posi-Shell conforms and adheres to any topography and delivers 100% clean runoff. Stockpile loading or removal is accomplished by breaking into the coating where desired. Active areas may be left open or quickly resealed if required. Posi-Shell erosion control coatings are ideal for protecting expensive piles of salt, coal, or cement clinker; and are used extensively for containing hazardous or radioactive soils.

Sediment and Nutrient Loads

by FTS     based in Victoria, BRITISH COLUMBIA (CANADA)

SedEvent is an event-driven, automatic grab sampling system that provides a simple and practical method of accurately determining suspended sediment and nutrient loads. While suspended sediment concentration (SSC) cannot be directly measured accurately or reliably, turbidity has been shown to be an excellent surrogate for SSC. Turbidity is caused by suspended particulate matter such as clay, silt, algae, organic and inorganic chemicals and acids like fertilizers, and microscopic organisms like harmful bacteria. These contents give water its cloudy or turbid appearance, and turbidity in natural waters is recognized as an important indicator of natural health. Measuring suspended sediment concentrations used to be labor-intensive, costly, inaccurate and impractical. SedEvent not only makes it possible and practical, it makes it simple.

Flow and analysis measurement for food industry

Application: Pipe with 0.3 m diameter. Part filled. Pipe made of HDPE. Shift production. Heavy flow fluctuation. Low sedimentation.

WEDA Underwater cleaning robots in lagoons and large fountains

by Weda AB     based in Södertälje, SWEDEN

The new Weda YT-5000 with a five (5) meter wide suction nozzler speeds up the cleaning process considerably. Estimated cleaning speed is up to 3000 sq. meters/hour. The cleaner removes efficiently bottom sedimentation (sand, algae etc.) from the bottom surface and pumps it to a selected discharge point (filter, waste etc).

SONARtrac - Dredging - Hopper Vessels

by CiDRA     based in Wallingford, CONNECTICUT (USA)

Soil density, hardness, lithology, and sediment particle size distribution can create slurry of variable makeup and density. At a constant pump speed, the slurry will have a variable flow velocity, which is undesirable and potentially dangerous. If the velocity is too low, there is a risk of sand outs in the pipeline. If the velocity is too high, the pump will wear and be inefficient. Traditional velocity flow meters with wetted parts are prone to wear, causing measurement inaccuracies, and require frequent, costly replacements. In addition, the presence of entrained gases may disturb the readings of traditional flowmeters and cause slurry density measurements to be inaccurate.

Erosion & sediment control solutions for water remediation

by Erosion Control Forum     based in Bend, OREGON (USA)

`Water should never be treated as a nonrenewable resource; it should always be treated with the respect it deserves as the foundation of life on the planet.` Most water on earth is in a continuous cycle between water bodies, land and the atmosphere. An important component of smart water solutions is the cycling of water treatment solutions using processes by which water enters, moves through and exits soil are essential for sustaining plants and soil organisms, transporting nutrients and recharging surface and ground water supplies. Water moving in soil also impacts the behavior and transport of soil solutes and their effect on water quality.

Water Treatment Solutions for Turbidity Removal

by Adedge Water Technologies, LLC     based in Buford, GEORGIA (US) (USA)

Turbidity is a measure of the loss of light transmittance through a liquid due to suspended particles. The more particles in the water, the murkier it looks or the higher the turbidity. This is a measure of the quality of the water. It is measured in units called Nephelometric Turbidity Units (NTU). Turbidity can be caused by run off after a heavy rain as erosion washes soil into a river or lake. It is often increased in the spring and fall when the water temperature at different levels in a lake change causing a turnover of those levels, bringing sediment, plants, and algae to the top.

XRF analysis for environmental applications

by Niton UK Limited     based in Woodmancott, Winchester, UNITED KINGDOM

Niton analysers are versatile environmental testing instruments that provide valuable assistance in portable soil testing applications such as brownfield site investigation. With the ability to analyse a wide range of materials, our instruments provide lab-quality soil/sediment chemistry in seconds. Lead, arsenic, cadmium, chromium, and other toxic metals contaminate sites of former industrial and agricultural activity around the world. Whatever the reasons for these occurrences, these pollutants cannot be ignored – particularly as environmental consciousness and regulatory initiatives grow.

Sediment Pollution Instruments

by Lindorm, Inc.     based in Medley, FLORIDA (USA)

Our SediMeter instruments are designed with sediment pollution monitoring in mind. They form part of a system with network and software components designed specifically to be the best possible sediment pollution monitoring system.

Remote monitoring stations

by FTS     based in Victoria, BRITISH COLUMBIA (CANADA)

The Water Survey of Canada, a division of Environment Canada, is a federal government agency responsible for collection, interpretation and dissemination of water source data and information. As a division of Environment Canada, the Water Survey of Canada (WSC) covers a vast range of topographical environs from Arctic Canada to the US border with elevations varying from sea level to over 13,000 feet (4,000 metres). An estimated 7% of the world’s renewable water supplies are found in Canada. Canada’s hydrology is incredibly diverse thanks to a wide range of bio-physical ecozones. WSC operates in partnership with all of the Canadian provinces, territories and other agencies, operating over 2,500 active hydrometric gauges across the country. The hydrologic and socioeconomic diversity found in Canada makes water resource management incredibly challenging.

Pulsair`s industrial mixers for oil & lubiricants industry

Our systems blends lubricants to specification usually within 30 minutes of adding all the ingredients used in your recipe. The result is a greater profit margin for you, the operator.

Agricultural, Storm and Highway Runoff

by FTS     based in Victoria, BRITISH COLUMBIA (CANADA)

The ability to collect useful data about sediment transport and other pollutants closely coupled to SSC (such as nutrients, e-coli, phosphates and nitrates) is dependent on the timing and frequency of manual grab samples during run-off events. Most sediment and pollutant is transported during a small number of storm events which are infrequent and unpredictable. When they do occur, trained personnel or the proper equipment may not be available to collect grab samples. An automated pump sampler can eliminate the need to sample manually, but for the expense of a rechargeable power system, the autosampler, and possibly a datalogger and a typical turbidity probe, you’re no better off. With an automated pump sampler driven by the DTS-12 digital turbidity sensor and controlled by the Axiom H2 datalogger, you obtain a better understanding of the water’s quality, while taking a minimum number of samples, reducing site visits and saving lab analysis costs.
