Hazardous waste treatment solutions for chlorine industry

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.

Industrial air pollution control for the chemical and petrochemical industry

CTP systems can be found in every leading production company: thanks to the experience and the expertise developed in partnership with our customers for processes with inconsistent waste gas volumes; varying concentrations of organic components; gases contaminated with aerosols. CTP has installed systems for waste gas streams ranging from 1,000 to 200,000 Nm³/h. CTP supplies this industry with mainly catalytic systems, regenerative thermal oxidisers (RTO) and adsorbers. As the flue gases in this industry are often explosive mixtures, CTP systems have to be completed with special safety conduits and filters to help reduce hazards during continued operation.

Analytical and measuring instruments of chemical and petrochemical

In the chemical field, ICP-AES is used for a broad range of analysis in order to manage trace amounts of hazardous metals in the manufacturing process, manage additive elements essential to the functionality of a product, and manage the environment of the entire factory. Therefore, it is desirable to have a robust, highly stable system able to reliably accept the injection of a broad variety of samples, regardless of the type of solvent (aqueous/organic) or the presence of matrices. It is also important to simplify processes and reduce costs, which enhances the productivity of daily quality control work.

Waste recovery for petrochemical wastes

Traditionally, the Petrochemical Sector has operated with basic technological solutions, with ultimate reliance on High Temperature Incineration (HTI) and landfill in order to deal with their hazardous wastes. However, tightening regulation, increasing landfill costs and social responsibilities are driving companies to look at alternative methods of treatment of very challenging wastes, including the treatment of:

Hazardous waste treatment solutions for site remediation

The contamination of soils as a result of prior chemical production can often be unpredictable and diverse. The majority of such pollutants will require an ex-situ treatment method. Many of our VacuDry units can be used for direct-feeding contaminated soils. To reduce the input amount for thermal treatment, the VacuDry units can also be used in combination with soil-washing plants: In this case, customers only feed the high polluted fractions and screened fines (e.g. below 10 mm), as well as the filter-cake from the soil washing process. However, we are able to handle soil contaminated with mercury, hydrocarbons, PAH, PCB, dioxins, furans, organic-lead compounds and many more. VacuDry plants for on-site ex-situ remediation projects are delivered in a modular design.

TOC Correlation to BOD or COD

Challenge: Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are traditional parameters analyzed in the laboratory to determine organic matter in water and wastewater. Wastewater facility operators need to have constant data to monitor their discharges and optimize treatment processes (biological treatment, chemical dosing, etc). The requirements of BOD and COD analysis prevent them from being implemented as control parameters, however. The BOD five-day analysis time requirement does not allow an operator to use the data for process optimization and. although COD requires less time than the BOD, its analysis includes the use of hazardous chemicals and has no constant analysis capability.

Integrated real-time gas analysis solution for chemical decontamination industry

The threat of terror in the form of chemical and biological warfare agents has been a reality globally since March 1995, when the Aum Shinrikyo sect killed 12 people and injured nearly 6,000 by releasing sarin nerve gas in the Tokyo subway system. More recently, the 2001 anthrax attacks in the USA was a wake-up call that the threat is real. Recent outbreaks of H1N1 and SARS posed threats of worldwide epidemics because air travel provides a means for these diseases to spread globally in less than 24 hours. A major concern of several US government agencies, such as the Department of Defense, Homeland Security, and the Centers for Disease Control and Prevention is not only the detection of hazardous chemical and biological warfare agents (CBWA) or bacteria or viruses that pose an epidemic threat, but the timely decontamination of those agents to a level where they no longer pose a threat to human health and life. The solution requires a means to monitor the effectiveness of the decontaminating reactant or reactants to an endpoint that has been reliably shown to be more than 99% effective in rendering the targeted agents harmless under controlled conditions.

Air pollution control (APC) equipments for pharmaceutical industry

The pharmaceutical industry worldwide is facing a major challenge. The productions of desired chemicals leaves an amount of by-products, some of them dangerous to both humans and the environment. An incinerator is usually used to deal with the challenge to reduce the volumes of hazardous substances. This process, however, creates sub-micron particles that conventional filter technology cannot handle. By using EnviBAT’s technology for gas cleaning – the best in the industry – such issues can be greatly reduced.

Early Warning Systems for Waste water industry

Physico-chemical parameters alone are not sufficient in obtaining reliable information on treated wastewater. Online toxicity monitoring must be performed in combination with routine chemical analysis. The assessment of biological effects of wastewater discharges in the ecosystems is today considered relevant and ecotoxicological tests identifying the ecological hazard are useful tools for the identification of environmental impacts.

Gravity Main Sulfide Odor Control with Hydrogen Peroxide

Gravity main sewer systems include major trunk lines and the tributaries that feed them. Hydrogen sulfide (H2S) odor builds up in the collections system as the flows collect from upstream reaches and become larger, deeper and more septic (oxygen depleted) in the downstream reaches more near to the wastewater treatment plant. In general, most of the more significant hydrogen sulfide odor and corrosion control problems occur in the major trunk systems segments conveying flow to the plant. Therefore, selection of sulfide treatment for gravity systems has several options depending mainly on: Duration of control required Degree of septicity (oxygen depletion) Location of target control points or "hot spots" Location of available dosing points upstream of "hot spots" Availability of civil infrastructure and utilities Sensitivity to hazardous chemicals
