Hi Anish,

We are based in Indonesia and I believe that many users are facing your difficulties. Many STP are old, their maintenance has been overlooked for years and owners face now critical challenges to meet at same time new regulations and fair return on investment. We have been involved retrofitting several STP over the last 5 years and indeed the task is not easy, when most drawings have disappear, specs and SOP totally neglected, breakdowns not recorded... If you do not have the budget to replace your failing STP, the common starting point is that you need to undertake a very detailed audit to clearly assess design, construction (including modifications if any), updated service conditions and your targets. Only at this stage you will be in position to talk about technology. We could communicate more in detail if you like. Do not forget to include in your financial calculations, the ongoing maintenance contract, the missing income from poor production, the potential fines from government, the energy impact ...

Good luck
