Displaying items by tag: treatment
Nouryon has introduced LumaTreat™, a global patent-pending smart-tagged polymer line of products that is revolutionary in the water management industry. LumaTreat products are fluorescent monomers that attach on a deposit control agent. The combination of the fluorescent monomer and deposit control polymer provide a Smart Tag that accurately measures the ‘free’ or unused polymer in the water treatment system.
The products are a breakthrough because LumaTreat can tag most polymers used in water treatment to prevent calcium phosphate, calcium carbonate and other deposits that, over time, produce scale deposits. To date, the industry has widely used pyrenetetrasulfonic acid tetrasodium salt (PTSA) in water treatment formulations. However, PTSA is an inert fluorescent tracer that only provides an estimate of how much formulation is in the water. LumaTreat enables customers to accurately measure ‘free polymer’ in the system, reducing the amount of polymer and water usage during the treatment process. This is a sustainable solution that both minimizes polymer consumption and conserves water.
“LumaTreat polymers contain high-purity (or active level) tagged monomers that provide accurate measurement of the free polymer and the amount of stress on the water treatment system,” said John Anderson, Sales & Marketing Leader, Industrial Specialties at Nouryon. “LumaTreat optimizes polymer and water usage under everyday conditions while preventing scaling during system disruptions, such as hot spots, pH pump failure or changing water conditions,” he said.
This version of LumaTreat is the first of three patent-pending compositions introduced by Nouryon, and targets water treaters who use PTSA. Nouryon is working in partnership with customers on additional versions to be introduced later. Nouryon’s patent applications are published as International Publication Number WO2020/243176 and WO2020/243180.
Another advantage for customers is that the LumaTreat polymers use the same fluorimeters found in PTSA technology so that water treaters can use their existing equipment. “This eliminates capital expenditure and ensures formulation costs won’t change significantly,” said Anderson.
“We’re really proud of the Nouryon team that has worked on this scientific breakthrough leading to a pending patent,” said Larry Ryan, Nouryon’s Executive Vice President and President, Performance Formulations and the Americas. “This innovation not only benefits the environment but also helps reduce costs for our customers. That’s a great win for everyone.”

Northumbrian Water has added four new centrifuges and a complete spare rotating assembly’s at a new energy-from-sludge facility serving its Bran Sands sewage treatment works in Teesside.
The project was a part of the overall £33-million scheme which uses anaerobic digestion to treat sludge from the wastewater treatment works, generating biogas which is used onsite in the CHP unit.
The centrifuges – Hiller Decapress model DP76–402 VAHY units – and spare assembly were supplied by MSE Hiller, via JN Bentleys
The Northumbrian Water project used CAMBI thermal hydrolysis process (THP), using heat and pressure to break down cell walls increasing enzyme hydrolysis and therefore digestion rates. This is said to lead to halve volume of sludge produced and significantly increase biogas quantity.
The new plant generates some 4.7 MWe from biogas which is used to power the treatment process. This has reportedly reduced the plant's reliance on natural gas to less than 10% of its former figures, aiding the path to become self-sufficient for energy.
Two of the new centrifuges are used to pre thicken sludge prior to the THP plant providing a controlled discharge of cake at 18 % dry solids at flow rates of up to 100 m3/hr each, explains MSE Hiller.
The HMR5000 control system and hydraulic scroll drive enables the machine to counter for variances in feed dry solids and continuously optimises machine performance, the supplier added.
Post THP the digested sludge is dewatered at flowrates of 35 to 70 m3/hr using two of the Hiller DP76-402VAHY centrifuges to a cake of over 30% dry solids. It can then be disposed off site as a Class A bio solid with no detectable pathogens and as a valuable agricultural fertiliser.
