Potable Water (Drinking Water) Treatment CoagulantsHardman manufactures a range of coagulants for water treatment at its site in Sydney, Australia. Whatever the application, Hardman can supply a coagulant that will suit your needs and your budget, whether it be for potable water treatment or for a specialised wastewater treatment problem. If unsure of the most suitable coagulant, our staff will be happy to advise you. You may already know exactly the type of coagulant you need, or alternatively we can run tests on your samples of water or wastewater in our well equipped NATA-registered laboratory. We can also advise on the use of Hardman coagulants for phosphate removal.  Hardman coagulants offer the following advantages:
• Less alkali addition (our coagulants are already hydrolysed
to a high degree).
• Better floc formation, leading to more rapid settling and
longer filter runs.
• Superior performance in removal of organic matter.
• Turbidity and colour.
• The ability to function at lower dosages, leading to lower
sludge volumes.
• Negligible heavy metal content.
• Very low residual aluminium concentration in treated water.
• Expert laboratory and on-site assistance in optimising
coagulant performance.
