One-Stage Deammonification Process - MBBR Versus IFAS Configurations - Development Updates and Application Considerations

The ANITA™ Mox Process is a single-stage deammonification process utilizing moving bed biofilm reactor (MBBR) technology. Early studies indicated that the Integrated Fixed-Film Activated Sludge (IFAS) configuration was an effective approach to improve ANITA™ Mox performance. Two studies on ANITA™...

Why Smart Water Networks Boost Efficiency

The Smart Water Network (SWAN) is the water utility industry’s equivalent to the energy industry’s Smart Grid. However, water utilities are trying to determine how new SWAN technologies will help maintain or improve service and profitability levels at existing water billing rates. This paper expl...

Online Analysis System: Modular end-to-end system for water analysis

The continuous analysis of water parameters is a costly procedure in practice. Usually, different systems with separate displays, different controls and individual sensors are installed. With the Type 8905 Online Analysis System presented for the first time at Hannover Messe Bürkert has developed...

SCADA Alternatives for Remote Monitoring

Most utilities employ a SCADA (Supervisory Control and Data Acquisition) system or DCS (Distributed Control System) to operate and monitor their process plants. Extending the SCADA network into the field seems logical and almost obvious if new investment in remote monitoring is required. For man...

How to Control Activated Sludge with Online Sensors

YSI's white paper delves into the concept of online monitoring and control in wastewater facilities. Its focus is the use of online instrumentation for control of wastewater treatment aeration. Activated sludge aeration systems can account for 25 to as much as 60 percent of total plant ener...

MBR Screening Selection Criteria

 The number of Membrane Bioreactor (MBR) treatment plants in design, construction and operation has increased considerably over the past decade. MBR operators as well as manufacturers of flat sheet and hollow fiber membranes technologies have realized through past experiences the importance...

Boost Capacity and Efficiency, While Minimizing Upgrade Costs in Water Treatment Plants

Many Water and Waste Water Treatment Plants (W/WWTP) are facing increased demand, but are limited by capacity and/or input power.  Also, the cost of electric power is a major portion of operating expense in these facilities. This paper covers two related topics.  First is a case study ...

How Payment Technology Can Improve Cash Flow

Your organization can accept cash payments at more than 17,000 7-Eleven, Family Dollar, and ACE Cash Express stores. These locations handle the transaction for you. They handle all the expense and risk associated with cash collection, all at an off-site location near where your customers live and...

Heavy Metals Water Testing - Powered by DNA

Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants -- such as uranium, lead, copper and mercury -- are one prevalent type of water pollutant. They are persistent in the environment once discharged and removal from source waters is n...

The Effectiveness of Total Organic Carbon (TOC) as the Defining Test for Wastewater Treatment Plants

As urban communities continue to grow, wastewater treatment facilities must grow with them. To meet the demands of the 21st century, quicker, more accurate testing with fewer sources of error must be employed. Traditionally, carbonaceous biochemical oxygen demand (CBOD) has been the defining test...

How Larger Flowmeters Speak Volumes

Water is money and the price of water is increasing all over the world.  As a result of these price increases, it is necessary for the water industry to have the most accurate methods of flow measurement available.  In large distribution networks flow meters over 48 inches in diameter m...

Remote Diagnostics Will Reduce Service Costs and Increase Uptime of Filtration Systems

Productivity is more reliable when equipment can be monitored to detect incipient failures and take corrective action before the plant goes down. But many devices, such as analog control valves, pneumatic valve terminals and field sensors, often do not offer diagnostic feedback, or it is not bein...
