Small-scale chemical dosing


Our Dura mini-packaged dosing system gives access to smaller businesses who require a dosing facility but may have found the cost of a full scale system prohibitive. 

The Verder Dura packaged dosing system is ideal for plants or sites requiring an effective dosing solution but on a smaller scale, such as effluent coming off a process into a holding tank before being returned to drain.

The system can operate as a long-term, small-scale dosing solution or as a mobile, rapid-response to an existing dosing facility failing. It can be a significant investment to ensure you are treating effluent from your process. The Dura mini-system also allows established dosing facilities to have a stand-by in case of break down. The system can be very quickly put in location and made operational.

A dosing & mixing capability

The system comes as a set; a packaged dosing rig and mixer system contained in a compact, lightweight and mountable frame.


The dosing rig

The dosing unit is assembled inside a PE UV resistant frame with bund/spill catch base. The frame can be free standing or hooked onto a standard IBC. The fluid is dosed using a Verderflex Dura peristaltic pump, which is controlled via a probe and analytic meter with an inverter to regulate the dosing rate. Power is supplied by simple plug-in 3 phase power. 


The mixing unit

The mixing unit is a frame-mounted dynamic mixer/agitator with collapsible blades. The frame sits on top of any standard IBC, with the shaft easily placed through the top port. The mixer is powered through the electrical distribution on the dosing frame.

System options

The dosing units can be scaled from 1l/h < to 130l/h. In addition to the pH meter, the unit may be operated with a flow meter, pulsation dampener or batch counter. The Verderflex Dura pump may be specified with different wet-side materials for chemical compatibility.
