Independent Mixing Stations

Program Setting for Flash Mixing & Flocculation Speeds & Times

Four independent stations/drives each with independently programmed sequential speed and time settings for flash mixing and flocculation stages.

Individual station Automatic and Manual mode selections.

Retention of LAST RPM and TIME settings (in AUTO) for ongoing tests.

Operates at a range of speeds from 20rpm to 200rpm - stepping up in 10rpm increments.

Each station's microprocessor maintains paddle speed via real time hall effect sensor feedback.

Paddle speed is relatively unaffected by variable test water viscosity, temperature conditions or jar size.

Digital Displays

14mm 3 and 4 digit numeric LED displays - RPM and Time.

3 step program to emulate flash mixing / flocculation stages or tapered flocculation.

Each Speed and Time display is common for Stage 1, pause and Stage 2 – selectable.

Compact & Portable

Backlighting

Extra low voltage, 2.4 Watt (total) LED lighting array.

Brilliant ice white light uniformly distributed.

Unique position of the light source, at bottom rear back pane, avoids potential interference caused by thermally induced currents that may hinder settling floc particles.

Suspended floc particles are illuminated against a black backdrop - maximises floc definition and contrast.

Facilitates observation of floc size, floc density, floc settling rates and supernatant/subnatant clarity.

Safety

Low 15 volt power supply with water resistant keypads - safe to operate in wet environments

Water resistant tactile keypads at each station include programming touch buttons, control mode and stage selection indicators (LED’s).

Easy to clean, water resistant, extensive use of corrosion resistant ABS, polycarbonate and acrylic materials;

Motor/gearboxes equipped with rubber power transmission type belts resulting in vibration free operation and low noise.

1 Litre and 2 Litre clear polycarbonate injection moulded jar accessories.

Easy- to-clean fillets at the floor and wall corner interfaces

Anti slip top lips for secure handling in wet environments.

Square jar emulation of full scale plant flocculator geometry.

Ample freeboard to avoid spillage

Unique Paddles

Radial flow clear polycarbonate paddles have uniquely tilted blades to induce a component of axial flow - ensures homogeneous suspension of fast settling flocs.

Clip-on/clip-off easy clean paddle sets to suit 1L and 2L jars.

Velocity Gradient Schedules

Translate plant velocity gradient to Jar RPM at a given temperature. From experience, operators will generally know the optimum plant velocity gradients for seasonal changes in water temperatures. These schedules provide the jar test speed required to emulate preferred plant velocity gradients. This information should take some of the “black magic” out of correlating test flocculation to the plant flocculation.
