A new generation of control valve

The IBS-series (photo) is a redesigned and technically revised version of this company’s Iris process-control valve. The new series features a compact structure with shorter installation lengths. The visual position indicator has been completely revised and is clearly visible from three sides, even from a long distance; this is in addition to the electronic feedback of the variable-speed drive position to the SCADA system. The valve’s gas-tight design without spindle feedthrough opens up many new possible applications for regulating chemicals and industrial gases. Leak-monitoring and flushing systems can be connected without changing the design. Its robust design and self-cleaning segments also make the valve a reliable regulator for raw sewage or sludge.

Mixers for efficient treatment of sewage sludge

Continuous Ploughshare mixers (photo) enable operators of municipal and industrial sewage works to tailor their treatment of wet and dry sludge entirely to its intended use. Wet and dried sludge that has been mixed and treated inside a Ploughshare Mixer in a continuous process boasts a pumpable consistency, exactly the right moisture content required to achieve the necessary calorific value and a particle size that ensures the proper consistency. This provides reliable protection against the sludge sticking or turning into a paste. Additives such as lime can also be added easily during processing. Ploughshare Mixers operate on the fluidized-bed principle. Specially developed shovels rotate close to the wall inside a horizontal drum, creating a fluidized bed. The process enables a high degree of homogeneity and constant reproducibility. Retention times, duration of treatment and other process variables can be modified depending on the characteristics being sought. Hall A2, Stand 520 — Lödige Process Technology, Paderborn, Germany

Innovation in sewage sludge drying

This company offers sludge drying systems (photo) for the treatment of sludge from municipal and industrial wastewater-treatment plants. The company made use of its long-term experience in thin-film evaporation and applied it to sewage sludge drying. The result is reduced energy consumption for sewage sludge drying. The company can now provide the use of a low-temperature heating source (down to 90°C); process scheme 1, which provides 10% saving in heating energy; and process scheme 2, which provides up to 45% savings in heating energy. The new options can be achieved with existing, well-known equipment and are already proven at pilot scale. Hall A2, Stand 120 — Buss-SMS-Canzler GmbH, Butzbach, Germany

Accurately measure turbidity with this portable device

The TB350 (photo) is said to be the most advanced portable turbidimeter on the market. It uses Multipath 90° BLAC (backscattered light absorbing cavity), a new, patented sensor technology. Two detectors are arranged at 90-deg, which ensures a purely nephelometric measuring principle. During the turbidity measurement, two different path lengths of the incident light beam through the sample are cleverly exploited. With the novel BLAC technology, the light-absorbing trap almost completely eliminates unwanted stray light and provides extremely accurate results for low turbidities down to 0.01 NTU. The TB350 has the accuracy of a laboratory measurement, but in a portable instrument. Highest accuracy is guaranteed in the lowest turbidity range from 0.01 NTU, while maintaining the precision level in the highest turbidity range up to 4,000 NTU. The TB350 is available as an infrared or white light version, is compliant with valid ISO 7027 and U.S. EPA (pending) regulations and standards.

Recovering phosphorous from sewage sludge — on site

The most promising phosphorus-recycling methods, in terms of sustainability, conservation of resources, effectivity and long-term cost-efficiency, are those processes in which phosphorus is recovered from sewage sludge directly on site. One such process has been developed by this company in cooperation with the CUTEC research center at the Clausthal University of Technology. It can be adapted to different recycling capacities and will be ready for commercial use in 2023. The recycling system can be added to a wastewater treatment plant, eliminating the need for transportation of the sewage sludge. The sludge is dried on-site and the phosphorus recovered — without incineration and ash storage and without using chemicals. The sewage sludge is fully utilized, generating marketable products. Recycled phosphoric acid, for instance, has a wide range of applications in a variety of industries. The process requires very little space and can be scaled to suit different recycling capacities, making it suitable for municipalities of all sizes.

Using ozone to combat micropollutants

Ozone breaks down trace substances through oxidation or converts them into smaller molecules, which are easier for micro-organisms to break down in a post-treatment stage or can be removed by means of absorption. This combination of processes delivers an improved overall cleaning result and generally removes more than 80% of trace elements from wastewater. At the same time, operating costs are lower than those of comparable technologies. This company’s new O3 system, Dulczon OZLa, can be fitted with up to 16 O3 -generator modules. The modules can be activated and deactivated as required. The amount of O3 produced can therefore be adapted to fluctuations, for example in a clarification plant where varying volumes of waste water are treated.
