Diluting the feed to a selected concentration is critical for efficient flocculant and solids interaction. The Vector® feed system is fitted with either a HydroPort (passive) feed dilution system, or a HydroForce (active) controllable feed dilution system depending on the application. Both units dilute the incoming feed to the optimal concentration.

The HydroPort self-regulating dilution system utilizes the difference in specific gravities between the incoming slurry on the inside of the Vector® and the supernatant water on the outside. This differential head causes water outside to transfer inside thereby diluting the feed. Uni-directional ports are used to ensure feed does not escape when the inside slurry density becomes too low and liquid levels start to equalise. This method is unique in design and no other vendor provides an effective one direction passive dilution system.
