Dilution Ejectors for Chemical Dilution

Chemical Dilution is a regular process commonly observed in the Chemical, Pharmaceutical & Water Treatment sector.
Generally the below media is subject to dilution
• Acids (Hydrochloric acid, Sulphuric Acid, Nitric Acid)
• Alkalis
• Caustic
• Lime

The dilution equipment is expected to take care of the following
• Ensuring the required concentration after dilution
• Ability to withstand corrosion due to the corrosive nature of the acids & alkalis

Dilution Ejectors are essentially liquid eductors that operate on the basis of the jet Venturi principle. Dilution Ejectors utilize the energy in pumped liquid (in most cases the diluting liquid) for their operation. Dilution Ejector operate by first sucking the chemicals through their suction inlet and mixing it with the diluting fluid inside the ejector. The high turbulence inside the ejector leads to intense mixing and a uniform diluted chemical is pumped out from the outlet of the ejector.

The range of ratio between the diluting liquid flow and the sucked chemicals depends upon the design of the ejector. For a Dilution Ejector in operation the concentration at outlet can be regulated by controlling the operating pressures. Thus the same Dilution Ejector can deliver multiple concentrations depending upon the concentration requirements

For continuous dilution requirement, Dilution ejectors are a perfect solution because of their inherent characteristics
• Ability to regulate the concentration of the diluted fluid at the Dilution Ejector outlet.
• In most of the cases service water is used for diluting the chemicals and the Dilution Ejector utilizes the same service water for its operation
• Can be manufactured in a large range of materials (Plastics, Stainless Steels, Exotic Materials)– it helps to select the best possible material compatible with the involved chemicals and reduces the risk of corrosion
• Dilution Ejectors do not contain any moving parts and have large internal passage areas, hence are not vulnerable to clogging by solid particles.
• As they have no moving parts, maintenance requirements are very less. Also it reduces largely the risk of abrupt breakdowns, helps in maintaining the regular production schedule.
