29.03.2022/XNUMX/XNUMX | More and more micropollutants are entering our water bodies through agriculture and industrial processes. Medicines and cosmetics in private households also lead to residues in the water. These substances are difficult to decompose biologically during wastewater treatment and can hardly be eliminated with conventional technology in the sewage treatment plant. Ozone is increasingly being used to remove pollutants as completely as possible from the wastewater during wastewater treatment. Prominent has the technology to do it.
Ozone is the strongest oxidizing agent in water treatment. It removes impurities highly effectively and reliably as well as in a way that conserves resources and is environmentally friendly. By means of oxidation, ozone breaks down traces of substances or converts them into smaller molecules. These traces of substances are more easily decomposed by microorganisms in the waste water in a post-treatment stage or can be removed by absorption. These combination processes improve the cleaning performance of the systems and usually remove more than 80% of trace substances from the wastewater. The operating costs are also lower than with comparable technologies.
In addition, ozonation reduces the germ load in the waste water. A discoloration and more COD reduction are other positive side effects. COD is a measure of the chemical oxygen demand in water and shows its organic load. The lower the CBS load, the cleaner the water. Contact time and specific dosage are decisive for the technical implementation. Ozone is produced in an on-site ozone generator.
Keeping ozone production economical is not easy. Due to the strongly fluctuating amounts of wastewater and the composition of trace substances, the amount of ozone fluctuates enormously. The new ozone plant Dzlcozon Ozla from Prominent is fail-safe and can be equipped with up to 16 ozone generator modules. The modules can be switched on and off as required. The amount of ozone produced can be adjusted to fluctuations, such as in a sewage treatment plant, in which a large or small amount of waste water is treated at times.
30.01.2015 | Endress + Hauser launches a new colorimetric analysis system for ammonium. Liquiline System CA80AM performs high-precision analyzes at all critical control points in water and wastewater treatment. With the indophenol blue method, it uses the legally compliant colorimetric standard principle. The operating staff of the sewage treatment plant can therefore rely on high-precision ammonium measurement according to ISO 7150-1, DIN 38406-5 and GB 7481-87.
Temperature Transmitter | Industry novelties and applications
Compared to the usual laboratory measurements, the online delivers Liquiline system CA80AM the values very quickly. The reaction to different ammonium concentrations at the inlet is improved and the aeration system in the activated sludge tank can be precisely fine-tuned. At the outlet, the CA80AM helps to achieve compliant ammonium levels and provide the necessary evidence for the water authorities.
The CA80AM features the user-friendly interface that plant personnel are already familiar with from other online analysis parameters such as pH or conductivity. The platform concept makes it possible to expand the analyzer into a measuring station: simply connect additional Memosens electrodes. Commissioning is uncomplicated with plug and play; Operating costs remain low thanks to automatic, configurable calibration and cleaning as well as long reagent life.
Laboratory automation accelerates Sars-CoV-2 diagnostics
The CA80AM sample preparations are suitable for all critical control points of Ammonium and they are available in three versions. Liquiline System CAT860 is very well adapted to the harsh conditions at the inlet. Its automatic backwash function with cleaning solution and air cleaning prevents the ceramic filters from clogging. Liquiline System CAT820 can be flexibly adapted to any sewage treatment plant for the aeration tank or the outlet.
