Nurnberg, Germany -- Controlotron and Siemens have signed an agreement whereby Siemens is to acquire the business activities of Controlotron, Hauppauge, New York, USA. Controlotron, a leading manufacturer of ultrasonic clamp-on flowmeters, employs a staff of around 120 and has a global sales network that is to be integrated into the Siemens organization. Take-over of the business activities is planned for May 2006.

According to Anton S. Huber, A&D Vice President, flowmeters account for around a quarter of today's requirement for process instrumentation: "The acquisition of Controlotron's flowmeter activities continues the consistent expansion of our process automation sector. Controlotron's innovative, non-intrusive flow meters are an outstanding supplement to our product portfolio in process instrumentation, consolidating our competitive position and making us an even more attractive partner for our customers".

The ultrasonic clamp-on devices from Controlotron calculate the flow of liquids or gases extremely accurately without intervening in the pipeline. Two sensors are clamped onto the outside of the pipe for this purpose. Key applications include the oil and gas industry, the water/wastewater sector, and energy and pipeline applications.

The Siemens Automation and Drives Group (A&D), Nuremberg, Germany, is the leading manufacturer in this field worldwide. Products supplied by A&D include standard products for the manufacturing and process industries and for the electrical installation industry as well as system solutions, for example for machine tools, and solutions for whole industries such as the automation of entire automobile factories or chemical plants.

New Optical Sensors for Blue-Green Algae

YELLOW SPRINGS, OH -- New fluorescence sensors from YSI detect pigments specific to blue-green algae (a.k.a. cyanobacteria). The monitoring of blue-green algae is of growing interest due to the problems some species can present through the production of toxins and compounds that deteriorate the quality of drinking water and through the formation of blooms. Blue-green algae are of interest for ecosystem studies and monitoring as well, where they may represent the most abundant primary producers in some environments. This is often the case in open ocean environments due to their efficiency in low nutrient conditions.

YSI's blue-green algae sensors optimize the limit of detection to allow monitoring of natural concentrations, typically low, of blue-green algae and identify when biomass is on the rise. An increase in biomass, generally associated with other changes in water quality parameters, can be indicative of a bloom and allow researchers or managers to take action before potentially dangerous conditions occur.

These two sensors use the in vivo fluorometry (IVF) technique, which measures the fluorescence of accessory pigments unique to blue-green algae: phycocyanin or phycoerythrin. Because there is no special sample handling or processing required, IVF is ideal for profiling, moored, and real-time data collection using YSI multiparameter sondes.

Multiple Options Available for Real-World Applications

Phycocyanin Blue-Green Algae Sensor (BGA-PC)

The BGA-PC sensor is designed for freshwater and estuarine conditions. Common applications in these environments include:
• Monitoring taste- and odor-causing species in drinking water reservoirs
• Detecting the presence of potentially harmful or toxic species as part of Harmful Algal Bloom monitoring systems
• Monitoring in agriculture ponds where blue-green algae can potentially harm livestock
• Ecosystem monitoring research where BGA impact primary productions and nutrient cycling

Phycoerythrin Blue-Green Algae Sensor (BGA-PE)

The BGA-PE sensor is designed for marine and estuarine conditions. Common applications in these environments include:
• Ecosystem monitoring research where microalgae represent important primary producers and impact carbon and nutrient cycling
• As a key sensor in a Harmful Algal Bloom monitoring system for long-term monitoring in sensitive coastal environments
• Momonitoring in or around aquaculture facilities where BGA can potentially harm marine stocks

To make full use of the optical fluorescence sensor technology, YSI is updating its multiparameter instruments, called sondes, with additional optical ports. A typical YSI 6-Series sonde, after a simple upgrade, can measure blue-green algae, optical dissolved oxygen (also new), turbidity, chlorophyll, temperature, depth, conductivity, and pH.

Comprehensive data points from YSI instruments, including blue-green algae, give researchers and managers valuable insight into the health of the aquatic environment in question and help to mitigate the effects of HABs.

Denver, CO -- The Awwa Research Foundation (AwwaRF), a nonprofit organization dedicated to advancing the science of drinking water, has issued 23 requests proposals (RFPs) totaling $4.8 million in research funding. The RFPs are due in May or July 2006, as specified in each RFP.

Collectively, the projects represent a wide range of topics of critical importance to the drinking water community. “Each year we target many of the water industry's biggest challenges, based on feedback from our members, leading professionals in the field and the results of prior research,” said Robert C. Renner, AwwaRF executive director. “AwwaRF research builds a body of knowledge that utilities and other water professionals can use to continuously enhance operations, improve drinking water quality and meet customer expectations.”

The 2006 RFPs include:

- Accuracy of In-Service Water Meters at Low and High Flow Rates;
- Assessment of Secondary Impacts of Corrosion Control on Distribution System Equipment;
- Asset Management Research Needs Roadmap;
- Changes in Water Use Patterns;
- Contaminant Risk Management Communication Strategy and Tools;
- Critical Assessment of Implementing Desalination Technology;
- Desalination Facility Design and Operation for Maximum Energy Efficiency;
- Drinking Water Source Protection Through Effective Use of TMDL Processes;
- Easily Distributed Mini-Pipe Loop System for Maintaining Corrosion Control for Lead and Copper;
- Effect of Nitrification on Corrosion in the Distribution System;
- Failure of Pre-Stressed Concrete Cylinder Pipe;
- Guidelines for Developing, Calibrating and Using Hydraulic Models;
- Impact of Phosphate Chemicals on Cement-Based Pipes and Linings;
- Impact of UV Location and Sequence on By-Product Formation;
- Impacts of Lining Materials on Water Quality;
- Minimizing Impacts of Changes in Watershed Vegetation on Source Water Quality and Quantity;
- Occurrence, Impacts and Removal of Manganese in Biofiltration Processes;
- Organizational Development Needed To Implement a Knowledge Management Strategy at Water Utilities;
- Residuals Treatment and Disposal Options for Low Volume Generators;
- Significance of Current Methods and Monitoring Strategies for E. coli and Total Coliform Measurements;
- Tools to Help Water Utilities Establish Customer Payment Programs;
- Water Conservation: Customer Behavior and Effective Communications; and
- Workforce Planning for Water Utilities – Successful Recruiting, Training and Retaining Operators and Engineers to Meet Future Challenges

All projects, unless otherwise indicated, must include 25% of the total project budget as in-kind or cash contribution. In-kind contributions can be in the form of labor, materials, or laboratory and other services, and may come from project participants such as water utilities, consulting firms and universities. For each project, an appointed project advisory committee will evaluate proposals based on responsiveness to the RFP, scientific and technical merit, and qualifications of the researchers.

Mr. Fields needs help with his sludge blanket:

Over the past couple months, I have noticed our sludge blanket in our SBR basin increasing. It seems the more I waste, the higher the blanket goes.

Right now, I am wasting 10 minutes. Does any one have any suggestions?(Click here to post a reply)

Thanks

Mr. Kendall needs help with winery wastewater:

Can anyone provide a table of typical winery waste strength?

I appreciate there will be a range of strengths due to seasonal variations and dilution due to washdown water etc but I figure if a get several sets of figures (preferably with references) I can quote with confidence.

I searched the web and got a couple of tables of info but not enough to be confident what "typical" really is.  Particularly after BOD, COD, SS and TKN.
