Jadair Water Settler/Clarifier

The Jadair Clarifier, manufactured under license by Rocktec New Zealand, is an intelligently designed, compact solution for industrial water clarification.
The Jadair concept utilises polymer flocculation and a computer controlled in-vessel system to guarantee clean, re-usable water and compact, de-watered solids.

How the Jadair works

• water and solids are separated by gravity sedimentation, enhanced by a proprietary polymer flocculation method
• water input and discharge can be by gravity or pumping
• suspended solids are allowed to settle on the floor of the Jadair water clarifier
• the Jadair can handle solids from about 0.3mm to 200 micron silt or clay (sizes above this will settle without the use of flocculants)
• the solids pile up, compact and the water is squeezed out
• the solids are so thick, they can be automatically (by computer control) scooped or scraped from within by special conveyor paddles
• the solids containment area in front of each module is large enough to handle two days' accumulation
• the solids themselves are so dry, they can even be piled up with a front-end loader or hauled away in trucks
• the Jadair-produced solids have a variety of uses, including landfill refuse cover, landscape contouring, brick manufacture and soil mixes.

Advantages

The Jadair has a number of advantages over traditional settling ponds:

• Range of capacities
  The Jadair system is available in capacities from 150 - 900 cubic metres, based on normal solid loading of 8-15 per cent by flocc'd volume.
  

• Modular
  If system usage exceeds original estimates, new Jadair systems can be installed right alongside existing Jadairs to increase capacity. One Jadair master system can run up to three side by side units without the need to duplicate controls and hydraulic power sources.
  

• Easily handled solids
  Typically, the solids produced by the Jadair are in spreadable form with a moisture content around the 28-35% mark, approaching that of a belt filter press but without the high maintenance and manning costs - a vast improvement over the wet slurry produced by older-style gravity settlers.
  

• Environmentally sound
  As the Jadair is a true closed-loop system, it is ideal for meeting requirements set by local councils and government bodies.
  

• Reduced water consumption
  The Jadair's closed-loop design ensures that water consumption is minimal and reclamation high. Water clarity is high enough to allow for mining process reuse.
  

• Small footprint
  Traditional settling ponds take up a large amount of land that could be used more productively. The Jadair's compact design ensures that available land is used to best advantage.
