soil loss Applications
The mercury cell process is a formerly widely-used production technique for the production of chlorine and caustic soda. The liquid metal, mercury, acts as cathode (negative pole) in this process. In the past, the loss of mercury during the process (to air, soil and water) led to serious health and environmental problems. Therefore, most European chlorine producers have decided to phase out the mercury cell process by 2020. Nevertheless, even today, almost 6000 tons of mercury is used per year for chlorine production in Europe alone. As a result of this, yearly waste outputs contain around 1200 tons of mercury, which are stored on-site or sent off for disposal.

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.

Coastal erosion is the wearing away of land or the removal of beach or dune sediments by wave action, tidal currents, wave currents, or drainage. Removing sand and other materials from beaches and dunes due to tidal storm surges and construction purposes causes massive beach erosion damages and land loss of seashores, thus destroying the natural heritage of the coast and reducing the vibrancy of the tourism industry. Uprooting vegetation from coastal areas destabilises beaches and clearing sites inland results in increased soil and dirt particles being washed offshore and smothering coral reef systems.

Nilex’s engineered erosion control and sediment control products reduce the damaging effects of rainfall, wind and wave action on soil structures while replacing or reducing the dependency on scarce natural resources.
Geosynthetic erosion control products are designed to reduce damaging effects of rainfall, run-off, and wave and wind action on soil structures by redirecting water flow or acting as a barrier between the soil surface and water.
Nilex Erosion Control systems include: Erosion Control Blankets (ECBs); Turf Reinforcement Mats(TRMs); Gabion systems; Concrete Revetment and Mattresses; and Cellular Confinementsystems.
Properly implemented sediment control practices can result in minimal soil loss, little damage to
off-site receiving channels, enhanced project aesthetics and fewer complaints from regulators and the public.
Nilex Sediment Control systems include: GeoRidge Bio; Silt Fence; Turbidity Curtains;SedimentSTOP and Wattles; and Water Inflated Dams.
