Chemical and Petrochemical Industry

The chemical industry is one of the most important industries. The industry is defined as the production of raw materials, intermediate and finished products. It includes organic and inorganic basic materials, but also the production of plastics, glass, detergents/personal care products and fine/specialty chemicals such as pigments, coatings/adhesives or crop protection agents.

The petrochemical industry is primarily involved in producing the precursors crude oil/natural gas. Among other things, these precursors are required to produce agricultural chemicals, cleaning agents or rubber/plastics.

Moreover, in addition to production wastewater, cooling or precipitation water also accumulates from rooftops, roads, production areas, transshipment sites or tank depots.

Challenge for Machine Technology

Depending on the product and production process (discontinuous/continuous syntheses), the requirements for wastewater treatment are very different respectively and may vary. Because water is used as a solvent, raw material, for heat transport, for cleaning products and for rinsing reaction vessels in the chemical industry, it may contaminate them with low and/or high amounts of raw, intermediate, by-products or main products in dissolved and undissolved form.

Despite the different compositions of the wastewater, all wastewater treatments have a biological stage which is followed by treatment and disposal of the resulting sludge. To maintain the function of the microorganisms, the respective wastewater must be individually pretreated. Depending on the production, the wastewater may contain corrosive, abrasive as well as fatty/oily components. High temperatures may also occur. Given this wide variety of requirements, expertise, quality and experience are indispensable when selecting suitable mixing and aeration systems.

Thanks to our extensive experience over many years, INVENT is the ideal cooperation partner for your project.

iCBA®-Aeration System

Settling contaminants such as sand not only impair the cleaning performance of a sewage treatment plant, but also cause serious damage to the equipment. The aeration of the sand trap accelerates and improves the settling behavior of mineral solids and thus prevents operational disruptions.

The robust INVENT iCBA®-Aeration System has been specially developed for harsh operating conditions. The durable stainless steel construction ensures long-term reliable gassing performance.

INVENT CYBERPITCH®-Mixer

HYPERCLASSIC®-Mixer

So that the wastewater can be discharged into public sewage systems or bodies of water, it must have a pH value between 6.5 and 9. Acids or bases are added for neutralization.

The INVENT CYBERPITCH®-Mixer with its robust design made of high-quality stainless steel is ideally suited for this thanks to its flow-optimized agitator blade shape and the design with regard to turbulent mixing.

The INVENT HYPERCLASSIC®-Mixer is used for neutralization when energy-efficient mixing of the tank contents is required.

INVENT iBC-MIX®-Tote Tank Mixer

In addition to setting an optimal pH value, the selection of a suitable stirrer is also essential for a successful precipitation reaction. For the destabilization of the colloidal state, a high energy input and rapid mixing between the precipitating agent and the colloid is required to form microflocs.

The INVENT iBC-MIX®-Tote Tank Mixer with an included traverse is used for processing and storage in lattice tanks, which suspends the heterogeneous mixture of substances with little energy consumption.

When conditioning the water, chemicals are added, which should be distributed as quickly and homogeneously as possible in the tank.

The INVENT HYPERCLASSIC®-Mixer has low shear forces due to its hyperboloidal agitator body shape and low speeds and at the same time ensures complete mixing of the container.

If high energy inputs are required, the INVENT CYBERPITCH®-Mixer is suitable thanks to its high speeds and robust design made of high-quality stainless steel. The INVENT HYPERCLASSIC®-Mixer is used to adjust the pH value and water hardness when energy-efficient mixing of the tank contents is sufficient.

Durch den Einsatz von Pulveraktivkohle (PAK) für die Behandlung des Abwassers wird eine große Bandbreite verschiedener organischer Kohlenstoffe (DOC) und Spurenstoffe eliminiert und die Abwasserqualität dadurch signifikant verbessert.

Anaerobic processes play an important role in many industrial and municipal wastewater treatment plants. In the process, organic compounds are fermented in the absence of oxygen and, via intermediate stages, methane, among other things, is produced as the end product.

If mechanical mixing is required for these processes, the INVENT HYPERCLASSIC®-Mixer represents an optimal solution. The agitator body is installed close to the ground and generates a strong radial bottom flow. In addition, thanks to its high pumping capacity, it ensures that the entire contents of the tank are thoroughly mixed and thus that the entire reactor is used efficiently.

Numerical flow simulation (CFD) is an important and reliable tool for checking the interaction of the building geometry (inlet and outlet situations, baffle plates, overflows, etc.) with the existing or planned installations. This allows the efficiency of the entire system to be evaluated under different load conditions. Possible weaknesses in the design, such as additional turbulence, which can generate an unplanned oxygen input, can be identified and optimized in good time.

In biological phosphorus elimination, the phosphate storage of the cells is prepared under anaerobic conditions and the supply of organic substrate. Thorough mixing of the activated and return sludge with the inflow volume flow is essential for this.

The INVENT HYPERCLASSIC®-Mixer, which generates a bottom flow directed radially outwards, is suitable for this. Activated sludge is transported upwards along the tank wall. At the water surface, the speed has reduced to such an extent that no oxygen is introduced. The phosphate content can be efficiently reduced through the even distribution of the activated sludge flakes in the wastewater.

In denitrification it is crucial that the activated sludge is homogenized with the recirculation and feed stream. Oxygen entry at the water surface must be effectively avoided.

The INVENT HYPERCLASSIC®-Mixer was specially developed for this. It generates both a high pump volume flow and a strong, radially outward bottom flow. Activated sludge is transported upwards along the tank wall. At the water surface, the speed has reduced to such an extent that no oxygen can be introduced.

INVENT iDISC®-Membrane Diffuser

INVENT HYPERCLASSIC®-Mixing and Aeration System

The ammonium in the wastewater is oxidized to nitrate by bacteria using dissolved oxygen. This requires an energy-efficient ventilation system.

The modular E-FLEX®-Aeration System has a flat design close to the ground. An oscillating movement of the EPDM membranes results in a high bubble separation frequency and thus creates very small bubble sizes with a long residence time.

The E-FLEX®-Aeration System can be delivered so that it can be lifted out for installation and maintenance work in filled pools.

The system can be combined with the INVENT HYPERCLASSIC®-Mixer and is suitable for intermittent processes.
The INVENT iDISC®-Membrane Diffuser is predestined for this. It is a highly efficient, fine-bubble membrane aeration system that is suitable for a wide variety of pool geometries due to its modular design.

The system can be combined with the INVENT HYPERCLASSIC®-Mixer and is suitable for intermittent processes.

The INVENT TEX-FLEX®-Aeration System with its robust stainless steel construction and textile membrane is the right choice for aggressive media.

The INVENT HYPERCLASSIC®-Mixing and Aeration System offers real advantages, especially for industrial use. The purely mechanical ventilation system reliably ensures an efficient supply of oxygen with a constantly low pressure drop. In stirring mode, it ensures optimal mixing of the tank contents.
