Arsenic is a naturally occurring element found in soils and groundwater. Arsenic concentrations vary in accordance with geographic location. When arsenic levels are found to be too high at a specific location, it may be necessary to treat water to remove it. Arsenic usually exists in two different forms, or valences, in a natural setting depending on the amount of oxygen available in groundwater. In more shallow aquifers with higher levels of oxygen, arsenic will usually exist as arsenate, As (V). In deeper,...
Cold Lime Softening: Hard water is water that has high mineral content. The name comes from the hard scale that forms when this water is boiled. It is not harmful to human health, but in the industrial setting it causes costly breakdowns in boilers, cooling towers, and other water handling equipment. The divalent cations Mg and Ca are the most frequently found minerals causing hard water. These ions enter water supplies by leaching from minerals in underground aquifers.
The term groundwater is used to describe the water that has infiltrated the surface of the earth and formed underground lakes that are referred to as aquifers. Groundwater monitoring consists of taking water quality and water level data, which are plotted and used to monitor changes in trends over time.
STS has been a hydrologist partner for many years, and through this work we have developed the experience to become specialists in the monitoring of river, lake and ground water levels. Measuring groundwater level 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.
UV disinfection is now a standard final treatment stage in most wastewater treatment plants worldwide. Our UV systems are widely favoured due to their environmentally friendly, chemical-free and ability to provide high-log reductions of all known micro-organisms, including chlorine resistant strains, such as Cryptosporidium. As growing environmental awareness and stricter regulations drive effluent discharge standards and water re-use initiatives to achieve greater performance, UV water treatment is fast...
Measurement of water quality in coastal regions and estuaries is critical in the characterization of hypoxic ‘dead zones’ as a result of nutrient loading and algal blooms in the water bodies. Sediment loading analysis through turbidity measurement is also important for coastal trend identification and modeling. Hydrolab and Sea-Bird Scientific offer a variety of multiparameter water quality instrumentation and nutrient sensors for long-term coastal applications. Sea-Bird Scientific water quality...
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.
The geotextile performs two primary functions when used in the construction of tunnels:-
1. Protection of the linear from abrasion and puncture by protrusions from the base surface of the tunnel well.
2.Drainage of water seeping through the rock and sprayed concrete layer. The in-plane oermeability of the geotextile enables the water to flow to a subsurface drainage collection system. where it is directed awa from the tunne
In modern times, development has already occurred on many of the sites desirable for the construction of housing. This has lead to developers increasingly turning to sites with less favorable conditions for new housing. In areas of low population, unfavorable subsoil, high groundwater table and slight decline of the ground, tradition sewerage systems based on gravity transport would lead to high investment costs. In these areas, the vacuum sewage system offered by Redivac is often the most feasible and the most...

Globally, groundwater is becoming increasingly polluted by the day. Given that 98% of our already limited freshwater supply comes from groundwater, Infinite Water is committed to supplying an affordable and effective process to treat and disinfect this water.
Groundwater hydrology is an interpretive science: we can’t observe the aquifers directly so we must interpolate and extrapolate our understanding from water-level measurements taken from observation wells. Stevens has expertise for measuring both water quantity and water quality.
The organization model of irrigation at the same level of the basin is considered one of the best ways to use efficiently the available water and the management of this resource. One of the most successful examples of this kind of Management is the Watering Communities. These communities are consortium of farmers in charge of the organization of the use of public, surface and subsurface water.
The dewatering phases in municipal processes are basically of biological sludge originated from purification processes. Bilfinger Water Technologies has realized many complete installations of sludge purification regarding the processes of water purification, purification of waste waters and SUW (solid urban waste) treatment.
ENTACT has successfully completed projects at a wide variety of transportation facilities including ports, rail systems, terminals, and airports. These projects typically require elaborate traffic control precautions as well as sophisticated shoring systems for protection of critical infrastructure. Our safety culture and in-house geotechnical expertise put us in a position to add significant value to complicated transportation related projects.
kwik-ZIP Centralizers are used on both casing and gravel packed screens. It is not possible to correctly grout a casing and maintain aquifer protection without the use of correctly designed inert centralizers at appropriate intervals to keep the casing from touching the borehole wall during grouting. Also inert centralizers should be used on all gravel packed screens to ensure centralization of the screen prior to gravel packing.
Piper Environmental Group, Inc. has partnered with Primozone Production AB in Löddeköpinge, Sweden for our municipal, groundwater, and wastewater applications. Our successful installations since 2015 have made our choice an obvious one. Primozone’s applications are in 30 countries worldwide, with documented OPEX (Operating Expense) savings that are key for companies and utilities who truly believe in a low carbon footprint, sustainability, and reducing their operating costs in maintenance, electrici...
