36 Water/Wastewater Tsurumi Aerators Deliver Clog-free Purification at Russian Water Treatment Plant
A team of aerators and an ejector system from Tsurumi (USA) are providing efficient and maintenance-free service at a water-treatment plant in Tyumen City, Russia. The plant, which provides clean drinking water for thousands of people, was suffering from regular shutdowns and rising costs caused by blockages. But the Tsurumi pumps have got things back on track.
Water in many parts of Russia is sourced underground and has a high iron content plus traces of manganese and silicic acid. These contaminants present a two-fold challenge for water treatment plants: they must of course be removed but in the process of that they cause damage to purifying equipment – aeration systems in particular.
Tyumen City’s water-treatment plant in south Russia is one example of a site where equipment has suffered from pumping such water. Previously, the plant relied on a pressurised aeration system of polyethylene pipes and air blowers. But the system failed to meet the latest industry standards and was susceptible to blockages. The air blowers also needed a large power supply and introduced more than four times the required amount of air, which generated surface foam. Plus the system needed cleaning at least once a month to ensure a good level of efficiency.
To increase efficiency at the facility – and reduce costs – Reshetilovs Russia, Tsurumi’s Russian distributor for aerators and sewage pumps, installed a mechanical aeration system consisting of two TRN aerators and a BER submersible ejector from Tsurumi. Once installed, in-house testing showed that maintenance for the system is required far less frequently, power requirements are reduced by up to 435 MW per year and efficiency yields remain higher for longer.
Water quality levels have also been improved. Samples were compared showing differences in the aeration processes, with an average of around 85% before the TRNs, while the new system increased this figure to between 86% and 95%.
“The new system is easier and cheaper to run, and it performs even better than before,” says Carsten Bode, aeration and sewage pump manager at Tsurumi Europe. “The plant no longer needs to worry about breakdowns, and the system provides even purer water for the region.”

Endress+Hauser (USA) introduces the OUSAF11 sensor for measuring optical absorbance by a process fluid. Using visible and near-infrared wavelengths of light, the OUSAF11 is ideal for product loss detection, interface detection, and suspended solids and turbidity measurements.
The sensor emits light in both the visible and near-infrared regions, and absorption by the process fluid is determined using an optical sensor mounted in the sensor head. The sensor is available in an immersion model for use in open tanks and basins, or in an insertion model with Tri- Clamp or Varivent connections that meet 3A Sanitary Standards.
The body of the rugged OUSAF11 is constructed of 316L stainless steel. The measuring head contains the light source and optical sensor, and it’s constructed of FEP fluorocarbon film. The fouling-resistant sensor head contains no glass. The FEP fluorocarbon film is non-reactive, highly transparent, resistant to sunlight, and has a high temperature rating. Additionally, FEP is accepted by 3A for sanitary applications.
The OUSAF11 sensor can be operated continuously up to 194 ºF (90 ºC), and up to 266 ºF for up to two hours, allowing it to be used in hot CIP processes.
The OUSAF11 is easy to install and commission. The sensor can be installed in a pipe, with the appropriate fitting, or suspended in an open channel or basin. The integrated cable is easily wired to the transmitter. The menu-guided interface on the CVM40 allows the sensor to be set up quickly. Interface to the transmitter can also be accomplished using a keyboard and the USB port on the transmitter.
The CVM40 has a full-colour graphic display, built-in web server, and Profibus, Modbus, Ethernet TCP/IP and RS232C/RS485 communications. It has four optical channels for input from sensors, and two universal analogue inputs that accept voltage, current, RTDs, thermocouples and other standard inputs. Outputs include up to six relays, a 4-20 mA output and digital pulse outputs. The instrument can support a range of sensors in addition to the OUSAF11 with its six digital input channels.

The CVM40 can be field or panel mounted. The CVM40 can also be programmed with math functions and linearisation capability to output in a preferred unit of measure.
Endress+Hauser manufactures the sensor and transmitter at its Conducta production facility in Anaheim, California, an ISO accredited facility. When ordered, the sensor and transmitter are tested and calibrated together as a system, ensuring optimum performance.

Retrofitting the TRNs was quite simple. They are installed quickly and cheaply as free-standing units, and are easier to maintain. They also deliver a more balanced mix of oxygenated water compared to air blowers that deliver a high concentration only in the areas in which they are positioned.
TRN aerators have a further advantage. Other aerators are susceptible to sediment that builds up during the aeration process because of rising pH levels. But Tsurumi’s aerators avoid this problem thanks to their unique design, which includes an Air-Seal-Principle. This ensures that the double mechanical seal never comes into contact with the aerated water, prolonging its operation without maintenance.
Tsurumi’s TRN series is its most advanced range of pumps. The auto-suction submersible aerators are used for communal industrial wastewater clearance and treatment with power outputs from 0.75 kW to 40 kW.
The BER series combine many of the TRN’s features with an ejector so that both agitation and aeration can be performed simultaneously. Power outputs range from 0.75 kW to 5.5 kW.
