Purification of exhaust air containing methanol

Medical technology

A cleaning solution containing methanol is used in the production of medical lenses. The resulting methanol vapours are extracted via the exhaust air duct and must be purified in order to comply with the limit value of 20 mg/m³ methanol before they are released into the environment. For this purpose, the exhaust air is led through the exhaust air purification module developed by uviblox, which consists of a UV purification stage with 120 UV-C lamps and a downstream activated carbon filter. Depending on the load of the exhaust air, the system switches the stages on and off.

Groundwater treatment plant for the purification of PFC and BTEX

on the former site of Tempelhof Airport

On the site of the "Old Port", in the central northern part of the former. From 2003 to 2018, groundwater contamination with BTEX was detected during investigations carried out at Tempelhof Airport. This is due to the handling of aviation gasoline (tank systems and tank farms) during the operating period of the "Old Port", from 1923–1945. In addition, MKW, PAH, LCKW, and PFT (perfluorinated surfactants) were detected at lower concentrations. PFT per-fluorinated surfactants (also PFC-perfluorinated compounds/chemicals) are available in concentrations of max. about 60 g/l contained in groundwater. The cause is the location of the renovation area "Old Port", downstream or by-stream of a former port. fire-fighting training grounds. PFCs have been used in extinguishing foams in fires of oil and fuel and are now largely banned.

Chlorine gas and hall air extraction system due to aggressive hall air

Buchholz

Clarios Recycling GmbH is a manufacturer of accumulators and has its own recycling plant for the recovery of raw materials from batteries and accumulators. When lead-acid batteries are accepted and stored in the storage boxes, it happens that chlorine gas is produced. In addition, in the recycling process of batteries and accumulators, sulfuric acid comes out, as a result of which acidic vapors are formed. Installed sensors register the concentration of chlorine gas and if the limit value is exceeded, the staff has to leave the hall so far.

Thanks to the newly installed extraction system, the chlorine gas is now extracted quickly and effectively, so that it is no longer necessary to leave production Hall D. In addition, a significant improvement in the quality of the hall air is achieved with the extraction.

Biological in-situ groundwater remediation

former glass factory in Achern

In order to control the implementation of a biological in-situ groundwater remediation on the site of the former glass factory in Achern, a modular remediation plant was manufactured in two insulated ISO sea containers. There are 5 production wells and 14 infiltration wells at the rehabilitation site.

The principle of biological in-situ remediation is based on the stimulation of pollutant-degrading microorganisms in the groundwater. For this purpose, groundwater is removed in the polluted area, nutrients are added and the area re-infiltrated. With the help of frequency-controlled well pumps and magnetic-inductive flow meters, the individual delivery rates between 0.5 and 3 m3/h are automatically regulated. The maximum total conveying rate of the remediation plant is up to 15 m3/h.

Groundwater treatment plant for CFC contaminated groundwater

Ostendstraße, Berlin Köpenick

At the Ostendstraße site in Berlin Köpenick, CFC (chlorofluorocarbons) damage was detected in groundwater in 2005, which has been hydraulically rehabilitated by the Harbauer GmbH groundwater purification plant since 2013. The measure serves to protect the transfer path to the Wuhlheide water treatment plants.

The raised water's CFC contaminations are removed using a three-stage desorption unit, and the resulting process exhaust air is burned in a catalytic oxidation plant to produce water, carbon dioxide, and hydrogen halides. The process air for stripping is circulated so that no exhaust air is produced.

Chemical washing for the purification of ammoniac-containing exhaust air

Rheinfelden

For the emptying of a large ammonia storage tank (about 5,000 m3), a chemical wash with 20% sulfuric acid was designed and implemented for the purification of ammonia-containing exhaust air.

During the chemical washing, the ammonia-containing exhaust air was brought into contact with the washing liquid (sulfuric acid) in countercurrent in a PE column, and the ammonia was subsequently dissolved from the exhaust air to form an ammonium salt in the washing liquid.

Construction water treatment plant for the removal of suspended solids and oil

Stockholm

At the Stockholm location, Harbauer GmbH has built and operated a plant for the treatment of construction water from a tunnel construction project.

The aim of the plant was to remove suspended solids and the oil phase from the wastewater. For this purpose, the water was passed over a 75 m3 sedimentation tank in the first process step according to a distributor template. This served to separate the floating oil phase as well as remove suspended solids.This was followed in the second process step by a further sedimentation tank for sedimentation of the remaining suspended solids.

Groundwater treatment plant for the removal of VOC, VC and BTEX

Krüllstraße, Berlin

Decades of laundry operation on Kiefholzstr./Krüllstr. in Berlin-Treptow/Köpenick resulted primarily in LCCW contamination in the soil and groundwater.
For cleaning the groundwater, Harbauer has built a groundwater purification plant at this location for a short time.

The contaminated water was conveyed to the plant via a regulated well pump and the flow was recorded with an inductive flow meter.

The first process stage consisted of two desorption columns connected in series, which converted LHC pollutants into the gas phase by the countercurrent principle. The column sumps served as a template for the pressure increase stages.

Remediation of chloraniline damage by means of Pump & Treat

Hauptstraße, Berlin

Between 1870 and 1990, the site at Hauptstraße 9-10 in 10317 Berlin was used, among other things, for paint and varnish production. The soil today is contaminated with a mixture of chloranilines, chlorobenzenes, and chloronitrobenzenes, typical for such farms.

A pump-and-treat measure was implemented for the renovation.
By pumping out contaminated water in the outflow, an additional groundwater sink is created, which ensures that further contaminated water flows in.

Biological groundwater purification of alkylphenols

Schönebeck

As a result of many years of commercial use of large areas of a former industrial estate. paint resin factory as well as partial surfaces of the former. Before 1990, considerable deposits of aromatics (BTEX and alkylbenzenes), polycyclic aromatic hydrocarbons (PAHs) and, above all, phenols (alkylphenols) entered the subsoil at the site of the diesel engine plant in Schönebeck (Elbe). The concentrations of both phenols are up to 120 mg/l and for BTEX, up to 10 mg/l.

The contaminated water is removed from three drains, then fed to the plant where it is cleaned and infiltrated into the subsoil via another horizontal drainage. This creates an underground flushing field in order to remove further pollutants from the soil matrix and clean them in the system.
