Malvern Panalytical Zeta Potential Measurement Solutions for the Water Industry

Zetasizer

Malvern Panalytical provides water treatment solutions that analyse the qualities of dispersed systems, including industrial bulk powders, high-concentration slurries, and aerosols and sprays.

The company’s innovative solutions have been carefully designed using extensive industry knowledge and expertise, and are regularly used by scientists and engineers across a wide range of industries to address challenges related to optimising productivity, as well as the development of high-quality products.

Zeta potential measurement solutions for water treatment

Malvern Panalytical offers automated, easy-to-use online and laboratory systems to measure the zeta potential of water samples.

These systems can be used to perform various tasks, such as:

  • Help maintain stable plant operation to required standards by enabling an effective, timely response to changes in water quality
  • Evaluate how much coagulant is required to optimise charge neutralisation
  • Eliminate coagulant over-dosing, reducing coagulant and sludge disposal costs

Water filtration monitoring

Pre-treated water typically contains organic, inorganic and bacterial contaminants.

Treatment begins with clarification, consisting of a coagulation, sedimentation and filtration process, which removes suspended particulates.

Stability of floc formation is critical during this process and it is controlled by neutralizing the electrostatic charge of various contaminants by using oppositely charged coagulants.

One of the known parameters that affect stability, zeta potential measures the level of electrostatic repulsion or charge between particles. It provides further details on the causes of aggregation, dispersion or flocculation.

Monitoring change with zeta potential measurements in water treatments helps lower the cost of chemical additives by optimising the dosage.

Laboratory technology for characterising particle size and zeta potential

The Malvern Panalytical Zetasizer Nano product range comprises high-performance and entry level systems that can combine various components, including:

  • Analysers: particle size, zeta potential or molecular weight
  • Protein mobility and microrheology measurements

Particles sizes less than a nanometer to several microns, as well as their zeta potential, can be analysed.

Online monitoring of coagulant process and measuring zeta potential

The fully automated Zetasizer WT system delivers lab quality online zeta potential measurements.

This enables efficient charge neutralisation and real-time monitoring of flocculation process performance. This information allows process operators to react to changes in raw water before they cause filtration issues, while reducing potential process upsets and chemical coagulant use.

About Malvern Panalytical

Malvern Panalytical was originally established in January 2017 via the merger of UK company Malvern Instruments and Netherlands-based PANalytical, which also included ASD and Claisse.

The company currently employs more than 2,000 personnel worldwide, operating research and development (R&D) and manufacturing sites across North America, Europe and China to offer comprehensive, hands-on customer support to its global customer base.

Malvern Panalytical is recognised as an industry leader in the materials characterisation sector and is committed to developing advanced analytical systems that deliver consistently high-quality results.
