    Sulphuric acid corrosion (pH control) on effluent pipework

    I am working on a project to neutralise alkaline spikes in our plant effluent to between pH 6 to 8, and am looking to use 50% or 98% sulphuric acid for this. The place in the system where I am considering injeting the acid is in a 200mm galvanised pipe which feeds the DAF (dissolved air...

    In-line neutralisation of Effluent pH with sulphuric acid

    I have been assigned to a project involving the neutralising of high pH spikes in our plant effluent. The effluent currently flows at up to 80 litres/sec (avg 30 litres/sec) in a 8" galvanised pipe from a contrashear pit (solids removal) via a buffer tank to a DAF (dissolved air flotation)...

    I am installing a small balance tank, 750mm diam, 1 metre tall, to handle 20 cubes/hr of juice flow. Will a conical base with the outlet at the bottom cause a swirling motion which I am trying to minimise? The tank has an anticlockwise tangential entry half way up, and we are in the southern...

For simplicity sake, this proposal utilises two centrif pumps in series, 20HP and 10HP although the first pump (20HP) would be sufficient for the task. The system...
