    ADVANCEES - Advanced water treatment equipments for desalination

    Areas that have no or limited surface water or groundwater may choose to desalinate seawater or brackish water to obtain drinking water. Reverse osmosis is the most common method of desalination, Sea Water Reverse Osmosis (SWRO) is a reverse osmosis desalination membrane process that has been commercially used since the early 1970s. Because no heating or phase changes are needed, energy requirements are low in comparison to other processes of desalination, though still much higher than other forms of water supply (including reverse osmosis treatment of wastewater).

  • Water treatment for landscape

    The sources of water for traditional landscape irrigation are many. They include municipal water, groundwater, and surface water; treated municipal wastewater treatment plant effluent properly treated to the standards of quality required for irrigation; and ever-increasing harvested rain, gray and storm waters. Issues confronting the landscape irrigation market range from treatment of alternate supplies to addressing iron removal in order to provide suitable quality water for any given landscape irrigation application. With our experienced staff of irrigation industry professionals, and in cooperation with landscape architects and consultants, we have the expertise and flexibility to select the best, most cost-effective solution for addressing any landscape market irrigation water treatment application.

  • Industrial water TOC and Color removal from water

    All surface waters contain varying amounts of naturally occurring organic acids. The most commonly encountered being tannic and humic. These substances have varying molecular weights and varying amounts of carboxylic functionality. There has been much interest in the removal of these substances from drinking water supplies due to their tendency to form THM`s when chlorinated. They can be removed effectively by use of anion exchange resins operated in the chloride cycle. Because the organics can be removed by regeneration with brine, this technology is far most economical.

    Ultraviolet disinfection systems for the de-chlorination industry

    The purpose of de-chlorination is the removal of free chlorine and combined chlorine compounds from potable water, as supplied by municipal water supplies. Chlorine will oxidize the surface of thin film composite polyamide membranes, causing the membrane to lose its ability to repel or reject salts. As a result, the membranes used in Reverse Osmosis (RO) or Electro-deionisation (EDI) systems will exhibit shorter lifetimes when exposed to chlorine in the water they are treating and membrane manufacturers will usually specify an upper limit to ensure a suitable life of the membrane. As a result, it is usual to use a method of dechlorination upstream of the RO or EDI system.

  • Erosion & sediment control solutions for water remediation

    `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.

  • Air control for wastewater treatment aeration

    Aeration Process Introduction: Waste Water Treatment removes impurities and contaminants from a com¬munity`s sewage utilizing a number of different processes and a variety of equipment. One of the processes is the use of surface aerated basins that use aerobic micro-organisms to remove 80 to 90% of organic matter in waste water. Oxygen concentration in the water basins is a critical factor to promote the optimum micro-organism growth rate needed to treat the water in the shortest amount of time. As a result, large compressors are used to force air through hundreds of air diffusion filters at the bottom of the aeration basins, providing a constant 24/7 supply of oxygen to the micro-organisms in the water.

    Aeration and mixing technologies for oil and gas wastewater treatment

    As more hydraulic fracturing wells come into operation, the stress on surface water and groundwater supply increases. The expanding volume of wastewater created needs to be captured, disposed of, or recycled in an environmentally sustainable manner so the EPA continues to increase regulations.  We will work with you to create a comprehensive solution to treat your wastewater, meet increasingly strict governmental regulations, and support long term water life cycle management.

  • Geosynthetic Lining for Highway and Civil Applications

    GCL can be used in highway and civil applications such as at airport de-icing facilities used to remove ice build up on the surfaces of planes. During the application process, glycol-based de-icing fluids can leak into local stormwater runoff, potentially causing pollution. CETCO GCLs were found compatible with de-icing fluid (glycol diluted 50/50 with water). GCLs can also be used to line roadway drainage swales for containment and prevent excessive percolation, thereby minimizing potential for groundwater contamination. Another example of using GCL in civil and highway applications is using the liner to contain acid rock and prevent runoff from entering the local water supply.
