Sludge Finder 2
Sludge Blanket Level Measurement
Sludge blanket level measurement is the technique of measuring the boundary between two material densities e.g. water and a slightly higher density sludge.
Developments within sludge blanket measurement technology over the last ten years have meant that sludge blanket level can now be measured, controlled and processes monitored with confidence and automation – meaning that previously used manual techniques, and the health and safety considerations that accompany them, can now be forgotten.
Pulsar’s Sludge Finder 2 has been providing maintenance-free sludge blanket level measurement automation worldwide since 2009.
Pulsar have installed thousands of sludge measurement systems worldwide, here a just a few of the applications to demonstrate the benefits of effective sludge blanket level measurement and Pulsar's Sludge Finder 2.
Exceptional Reliability - Customer Confidence in Complex Application
Customer: Dwr Cymru Welsh Water, Wales, UK
Process: Sludge Finder 2's exceptional reliability within previous installations gave customers the confidence that it could work successfully in a complex application with sludges from different processes that gave variable composition going into thickeners. Read the full case study.
Automation and Control - Replacing Unreliable Manual Techniques and Environmental Compliance
Customer: Wessex Water, England, UK
Process: Sludge Finder 2 replaced outmoded dipping probes which were unreliable and led to readings often including 'spikes' or 'flatlines' that would activate the RAS valves unnecessarily - using excess energy and making it more difficult to control the sludge blanket. The Sludge Finder 2 installation meant more accurate control of the process and made it easier for the company to comply with environmental consents. Read the full case study.
Energy Efficiency - Using Sludge Measurement to Power A Whole Wastewater Treatment Plant
Customer: Severn Trent Water, England, UK
Process: Sludge Finder 2 is used to increase sludge density transferred to digesters from an average of 2% up to 6% - resulting in energy generation of 5.5MW (5500KW) at full power. The site now powers all equipment on site and returns surplus energy to the grid. Read the full case study.
