Oil and gas dutyHow Hexa-Cover® works
The tiles are poured onto the liquid from big bags. Their ribbed hexagonal shape makes them spread out and settle edge to edge, forming one floating layer that covers up to 99% of the surface.
- Any shape, any size. Round tanks, rectangular basins and irregular lined ponds.
- Follows the level. The layer rises and falls with the liquid and rests on sloped banks.
- Full access. Pumps, sampling and aeration carry on as before.
- Nothing to maintain. No running, repair or inspection cost.
- Recycled material. Solid tiles moulded from recycled polypropylene, with no hollow chambers to crack or leak.
Covering a 3,500 m² pond in two hours.
Tested, certified and measured in operation
DLG APPROVED
Independent test by the German Agricultural Society on pig slurry: odour reduced by 81 to 96%, and ammonia by up to 98% (DLG test report 7593).
Drinking water certified
Certified for use in contact with potable water to AS/NZS 4020:2018.
Measured by a water utility
East Gippsland Water in Australia reported 95% less algae biovolume and 89% less E. coli in its raw water reservoir after covering it.
What customers say
Before installing the Hexa-Cover® our customer, a brewery, had many complaints from neighbors about the odor. After the installation the problem is solved.
We installed 108,000 Hexa-Cover® discs in June 2017, and since have seen a notable reduction in algae growth and E.coli in our raw water storage, which makes the water much easier to treat.
There is no clogging of filters because of algae and this means no stoppages at the plant, which again means huge savings in our operational costs.
