The energetic crisis is increasing the need to reduce the energy consumption of air filtration and air conditioning installations due to its high energy cost and the need to reduce CO2 emissions.
For this reason, when renovating and designing ventilation and air filtration systems, it is essential to find solutions that reduce energy cons
There are three commonly used technologies for the prevention and control of odor gases:
1: chemical scrubbing
The chemical scrubbing treatment system consists of passing the gas through scrubbing towers where air/water/reagent contact takes place. In chemical scrubbing, an acidic or basic chemical solution is injected into the system from the top, passing through the flow of the gas, and is then recovered at the bottom of the tower for recovery
The presence of microorganisms in wastewater causes a decrease in dissolved oxygen as it is consumed in their metabolism. The greater the number of microorganisms, the greater the biological demand for oxygen. When this demand exceeds that which can be provided by air exchange, then an anaerobic process begins, creating a reducing environment that favors the release of odor-causing compounds in WWTPs:
- Sulfur derivat
Controlling odor problems in sewage collectors and wastewater treatment plants is currently one of the main objectives to reduce and prevent potential problems related to worker safety and minimize the negative social perception that odor problems can generate.
The main sources of odor generation in WWTPs are the phases in anaerobic conditions, where the lack of oxygen favors the development of sulfate-reducin
Odour treatment in sewage tunnel ventilation ducts
Case Study: Izmir Wastewater Plant (Turkey)
Project Description
BION`s distributor for municipal, biogas and odor treatment applications in Turkey, Biotek, has recently won a contract to supply equipment and filter media for odor abatement from ventilation ducts in wastewater tunnels in the municipality of Izmir, managed by IZSU.
These tunnels are used to remove s
It is a fact that corrosion has a significant economic impact on an industrial scale. As an example, the results of a study carried out in the USA showed that the estimated annual cost due to corrosion was $276 million, which is approximately 3.1% of the country`s gross domestic product (GDP). It is logical then that, during the last decades, great efforts have been invested to face this problem and significantly improve corrosion management, offering better solutions, better equipment and ne
Odor Control in Pesticide Plants: Volatile Elimination
Chemical formulation plants are susceptible to emissions of unpleasant volatile compounds and unpleasant odors, which makes it essential to implement effective odor control treatments.
Specifically, in the northwest of Spain, there is one of the oldest industrial locations for the manufacture of phytosanitary
The Catalan Water Agency (ACA) commissioned a project to minimize the emission of odors from the primary sedimentation tanks of the Wastewater Treatment Plant (WWTP) of Cambrils (Tarragona), emissions that usually generated complaints from the neighborhood.
BION was selected as the candidate to carry out an interesting project that consisted in the treatment of gas phase pollutants (mainly H2S)
BION has successfully carried out the elimination of toxic and corrosive gases, we are referring to H2S and Ammonia, from the hazardous waste blending and neutralization project that the company Hidronor, Gestión y Tratamiento de Residuos, carries out in the town of Noviciado near the Arturo Merino Benitez International Airport in Santiago de Chile. Its work process generates an important emission of gases fro
The environment in a refinery is highly corrosive, which makes it necessary to implement control systems not only to protect people but also the equipment that controls the processes to ensure their reliability.
Bioconservacion has equipment specially designed for the safety of people, to protect against corrosion in control rooms and cabinet pressurization equipment. Some CEPSA refineries in Spain have instal
