Complete system to inject chemicals in
liquid streams. Typically a water flood system consist of a filter, deaerator, etc. which
utilize the following chemical feeds:
1.Polyelectrolyte: This is used as a
coagulant aid which unites small suspended solids (which would normally escape filter
media into effluent) into bigger particles facilitating their capture by filter
media.
2.Biocide: Is used to kill the bugs in
the water. Normally a shock treatment of 3-4 hours at 400-500 ppm is given per week to the
water flood system at the filter inlet.
3.Chlorine: is continually fed to kill
certain bacteria and stop the growth of algae.
4.Corrosion inhibitor: Prevents corrosion
of piping and equipment.
5.Scale inhibitor: Prevents scaling in
the piping and equipment, etc.
6.Oxygen Scavenger: Removes dissolved
oxygen in water. Dosage of oxygen scavenger depends on the level of dissolved oxygen in
the water which depends on the water temperature. For every part of dissolved oxygen,
normally 6-10 ppm of oxygen scavenger is being used i.e. hydrazine, sodium sulfite
ammonium bisulfate, etc.
