Jadair Water Settler/Clarifier

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.

In operation, water and solids are separated by gravity sedimentation, enhanced by a proprietary polymer flocculation method, and suspended solids settle on the floor of the tank, from where they can be automatically (by computer control) scooped or scraped from within by special conveyor paddles. 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) and the solids themselves are so dry that they can be handled by a loader or hauled away in trucks. These resultant solids have a variety of uses, including landfill refuse cover, landscape contouring, brick manufacture and soil mixes.

The Jadair has a number of advantages over traditional settling ponds, and is available in capacities from 150 – 900m³, based on normal solid loading of 8-15 per cent by volume. The system is also completely modular so additional systems can be installed alongside existing units to increase capacity. One Jadair master system can run up to three adjacent units without the need to replicate controls and hydraulic power sources.

Typically, the solids produced by the Jadair are in spreadable form with a moisture content around the 28-35% mark, a vast improvement over the wet slurry produced by older-style gravity settlers. Being a true closed-loop system, it is environmentally sound, meeting all requirements set by local councils and government bodies, and the design ensures that water consumption is minimal and reclamation high. Water clarity is high enough to allow for mining process reuse.

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