Polymer Feed SystemsAslan Technologies

Aslan offers two lines of Dry Chemical Feeders to meet a wide variety of customer requirements.  The DFC and DFC Mini series provides a continuous feed of aged polymer or chemical thereby eliminating the need for an age tank and its associated mixer.  The DF series is a more traditional batch make down system.  Liquid polymer can be made down with either the LF series system.  In addition, the DFC dry system comes with liquid chemical capabilities for liquid backup or biocide or deformer chemicals.

Dry Chemical Feeders: DFC Series

DFC Series of Continuous Polymer Make down systems is the complete answer to dry polymer make down with neat liquid feed backup. A completely aged and activated solution can be prepared with either a DRY or NEAT LIQUID polymer source. The system is designed to run unattended between bulk fillings of the hopper. The liquid polymer backup can also be used to feed a biocide or anti-foaming agent into the polymer makedown process.Polymer Make Down Equipment

The system is setup with a medium to high concentration of polymer. This allows a greater holdup of aging product, resulting in a floor space savings since less water is stored. Even on cold water, the DFC works very, very well.

The process starts by metering a precise amount of powdered DRY or NEAT liquid product into the high velocity water layer of the primary wetting stage. The solution is then positively circulated through directed pathways and orifice plates using 3 to 5 separate mixing chambers.

The use of powerful low-shear mixers and the reduction of the mixing action imposed during each stage allows the DFC Feeder to achieve maximum product activation without damage to the polymer chains.

The final stage accurately meters water into the final storage chamber (Secondary Dilution Tank) with a gentle mixing action to prepare the final solution to the dilution best suited to the process. 

In addition, the DFC Series feeders can make down CLAY, CMC or SALT solutions.

Dry Chemical Feeders: DF SeriesPolymer Make Down Equipment

The DF Series is a selfcontained, fully automatic dry polymer batch makedown system. Complete with large capacity bulk product storage, the system is designed to run unattended between bulk fillings of the hopper.

The system meters a precise amount of solid powdered product into the high velocity water layer of the Turbo-Cone® dispersion wetting cone then through a high velocity eductor eliminating any possibility of dusting.

The solution is then positively circulated through a fixed-orifice diffuser by a high velocity mixer to achieve 100% product dispersion. A gentle low shear high flow agitator provides age tank movement for the duration of each batch to allow activation over a precise age time without damage to the polymer chains.

The last two stages are both operator controlled on, off and total time cycle via the touchscreen user interface allowing the operator to select a very precise amount of high and low energy aging to optimize age time without sacrificing product efficiency due to over-shearing.

Liquid Polymer Feeders: LF Series

Polymer Make Down Equipment

The LF Series of continuous polymer systems are the complete answer to neat liquid polymer makedown.

The process is setup with a high concentration of polymer allowing a greater holdup of aging product, resulting in a floor space savings since less water is stored.

The systems are designed to run unattended between fillings of the polymer tote.

Lower polymer concentrations are also possible.

The high velocity water layer of the primary wetting stage combined with the rapid recirculation of a tight loop to ensure a high mixing energy zone for a very short duration.

The polymer then quickly leaves the system to achieve maximum product activation without damage to the polymer chains. Hard to mix polymer? NO PROBLEM, just add the upgraded pump for a greater mixing action.

Note *The DFC Series of Continuous Polymer Make down systems also makes down liquid polymer as well as its original intended function of dry polymer.  Whether it is a liquid polymer backup to dry or to provide liquid polymer makedown and aging tanks all in one convenient system, the DFC Series is always a great choice.
