  • Services related to the Environmental Impact Assessment (EIA)

    • Environmental Impact Assessment (EIA) is a complex of measures aimed to identify the character, intensity and severity of impact on the environment and public health caused by any kind of planned economic activity. • The purpose of an EIA is to develop the necessary measures to prevent the harmful effects of the proposed economic activity on the environment or minimization of this influence if you can’t eliminate it. EIA is carried out during the design phase, before the construction of the facility. • As a result of the EIA customer receives information about the character and extent of the environmental impact of the proposed economic activity, information about alternative methods of implementation, assessment of the environmental and other related impacts caused by activities of the enterprise.

  • Water quality monitoring for environmental industry

    Maintaining the quality of natural waters provides numerous economic benefits by preventing severe deterioration of water resources that would require expensive treatment operations to protect public health and the environment. For instance, monitoring nitrates in surface waters can possibly prevent algal blooms from happening by facilitating the necessary steps to stop pollution sources from discharging nitrogen nutrients into the water system.

  • Environmental Monitoring

    Environmental monitoring is becoming more important every day in local, national and international policies, showing the environmental awareness demanded by society.

    This fact gives rise to an increase in the amount of legislation that obliges companies to law enforcement. Thus, the necessity of making more pollutants controls means high analysis expenses to the companies, which need to subcontract this service.

    Although applications in this area advance, there is still a clear demand to get new portable and versatile analysis systems for many different application fields such as pollution in environmental or waste waters, monitoring nutrients in agricultural or horticultural water as well as general process control in chemistry industry. Because of the number of enviromental analysis required, there is a need for screening and monitoring measurements of these compounds at contaminated areas.

    Traditional monitoring techniques are typically based on laboratory analysis of field-collected samples that require considerable effort and expense, and the sample may change before analysis. Moreover, the equipment currently available is too large and expensive and it cannot be made portable.Alternatively, microfluidic and electrochemical sensor technologies can contribute to the development of new portable monitoring systems, complementing standard analytical methods for different environmental monitoring applications.In this way, the decentralization and integration of all those typical analyses is the paramount importance in order to reduce cost, simplify the analytical process and make more accessible these technologies to end-users. The development of portable, robust, and accurate Lab-on-a-Chip systems to monitor priority compounds such as contaminants, explosives, chemical warfare agents, inorganic and organic ions is a demand of modern society. Portability allows analyses to be carried out outside of the laboratory, minimizing the risk of contaminating the sample and leading to a faster response time at a lower cost.

    Thus, MicruX solutions and technologies open the gate to develop portable and esay-handly Lab-on-a-Chip devices in order to improve pollutants in-situ analysis in a very economic and efficient way.

  • Landfill Leachate Treatment

    Effluents from waste (leachate) are highly polluted and must be treated efficiently before they can be discharged into a municipal sewage plant or a local watercourse. Conventional treatment technologies do not suffice. Chemical processes are not economic due to the high pH buffer capacity of the leachate. Hardness and chlorides in the leachate are a problem for many plant components. Besides, process knowhow and operating experience are indispensable for an effective elimination of the harmful ammonia nitrogen. Certain processes also produce residues such as concentrates, which must be removed from the landfill body. This disposal is very expensive. WEHRLE is a reliable and experienced plant constructor for those applications. The first leachate treatment plants were built in 1991 and have been in constant operation ever since. This is not only proof of excellent technology but also for sustainable efficiency with stable, predictable, low operation costs.

    Drill Cuttings Plants For Oil and Gas Industry

    Common drilling procedures for oil and gas, used widely around the world, produce a consistently increasing amount drill cuttings containing oil. In some cases, drill cuttings even contain other hazardous components such as mercury or NORM (Natural occurring Radioactive Material), requiring special attention. Treatment of drill cuttings is therefore beneficial from both an environmental and an economic standpoint, allowing valuable drilling oil to be recovered, and ensuring environmentally sound disposal of the drill cuttings. Our VacuDry technology is designed to safely separate oil, water and mercury from the solids (including NORM), allowing reuse of the oil and safe disposal of the water, mercury, solids and NORM.
