  • Zero Liquid Discharge wastewater solution

    Zero Liquid Discharge (ZLD) describes a process that completely eliminates liquid discharge from a system. The goal of any well-designed ZLD system is to minimize the volume of wastewater that requires treatment, process wastewater in an economically feasible manner, while also producing a clean stream suitable for reuse elsewhere in the facility. Interest in ZLD technology has grown in the industrial manufacturing sector over the past decade. Companies may begin to explore ZLD because of ever tightening wastewater disposal regulations, company mandated green initiatives, public perception of industrial impact on the environment, or concern over the quality and quantity of the water supply.

    Ultraviolet disinfection systems for the de-ozonation industry

    Ozone is an allotropic form of oxygen; each molecule contains three atoms of oxygen instead of the usual two.  Ozone is a powerful disinfectant and has been used commercially for the treatment of potable water since 1904.  It is produced on site in the same way that ozone is formed naturally, by the discharge of electricity during a thunderstorm.  A high voltage is passed across a gas stream containing oxygen.  This method of ozone generation is called corona discharge.  The energy of the high voltage splits an oxygen molecule (02) into two oxygen atoms (0) - which recombine with ordinary molecules of oxygen (02) to form ozone (03).

  • Sulfide Oxidation with Hydrogen Peroxide (H2O2)

    Sulfide Odor Control Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing sulfur (e.g., coal, gas and oil) being refined into industrial products. For a variety of reasons - aesthetics (odor control), health (toxicity), ecological (oxygen depletion in receiving waters), and economic (corrosion of equipment and infrastructure) - sulfide laden wastewaters must be handled carefully and remediated before they can be released to the environment. Typical discharge limits for sulfide are < 1 mg/L. Sulfide Treatment Alternatives There are dozens of alternatives for treating sulfide laden waters, ranging from simple air stripping (for the low levels present in groundwaters) to elaborate sulfur recovery plants (used to treat several tons per day at refineries and coal burning power plants). There are processes based on biology (using compost filters, scrubbing media, or inhibition/disinfection), chemistry (oxidation, precipitation, absorption, and combination), and physics (adsorption, volatilization, and incineration). Each process occupies a niche which is often defined by the scale and continuity of treatment, whether the sulfide is in solution or is a gas, the concentration of sulfide involved, and the disposition of the sulfide containing medium. However, for reasons relating to convenience and flexibility, chemical oxidation (using hydrogen peroxide) continues to grow in its scope of application. Treatment with Hydrogen Peroxide While other peroxygens such as permonosulfuric (Caro’s) acid, peracetic acid, and persulfates will oxidize sulfide, their use for this application is overkill. Hydrogen peroxide (H2O2) is considerably simpler and more cost-effective. H2O2 may control sulfides in two ways, depending on the application: Prevention - by providing dissolved oxygen which inhibits the septic conditions which lead to biological sulfide formation; and Destruction - by oxidizing sulfide to elemental sulfur or sulfate ion.

    Industrial wastewater solutions for container cleaning wastewater

    Flexible, turnkey solutions for container cleaning. Cleaning industrial containers such as canisters, vats or IBCs produce large volumes of effluent. The type of impurities in this effluent depends heavily on what has been transported in the containers. That’s why effluent treatment requires a flexible system able to cope with all conceivable contaminants. Reconditioners are increasingly using modern vacuum distillation systems to do this. They work fully automatically, guarantee a high level of process reliability, minimal residue, and render a zero liquid discharge container cleaning process.

    Industrial wastewater solutions for vehicle and transport cleaning water

    Reliable and effluent-free: VACUDEST in vehicle and transport cleaning. Means of transport have to be one thing above all else: Safe. That’s why the vehicles regularly undergo strict quality checks. They are thoroughly maintained, serviced and repaired, and this of course also includes careful cleaning. Effluent is produced which, due to the high degree of contamination, cannot be discharged into the public sewer system. It contains oil, grease, detergent and other impurities. This effluent is very expensive to dispose of. Internal treatment of such wastewater is a cost-effective alternative to disposal.

  • Oil water separation for the food industry

    Packaged-food producers frequently use and then must discard large batches of cooking oil used in their process. Usually they drain most of the oil directly from equipment, but they must remove residual oil by regularly washing fryers, ovens, conveyors, and other machinery. 

    The oil mixes with the wash water and becomes part of the plants wastewater stream. Having oil in wastewater complicates the wastewater-treatment process by making it more expensive, more time-consuming, and less effective. Additionally. as with other manufacturers, packaged-food producers want to reduce waste and decrease the environmental impact of operations. That is why removing used oil and solids from wastewater before it is discharged is a priority.

  • Patented Waste Water Recovery System for Marine Refinishing Industry

    Due to recent expansion of EPA regulations regarding discharge of water containing contaminants, owners of boats and marinas have had to heighten their awareness regarding waste water containment. If caught discharging any contaminated water overboard, even an ounce or less of light oil mixed with bilge water will produce a visible sheen on the ground or on the water. This is identified by the EPA as a reportable discharge, of which large fines are possible including clean-up costs, and even criminal prosecution when flagrant violations are detected. The GEOMAT Waste Water containment system can be customized to fit any size marine application such as refinishing, marine detailing, and waste disposal.
