The PVA gel beads contain a network of tiny pores, about 20 microns in diameter. The pores support the growth of up to 1 billion bacteria inside each bead. The small pore size excludes metazoa or protozoa which consume and reduce the effectiveness of the active bacteria. The pores in the PVA gel allow easy entry for oxygen and nutrients to feed the bacteria colonised inside the beads. After the bacteria die, they stay inside the beads where they are consumed by the next generation of bacteria, rather than dropping to the bottom of the tank and becoming sludge. The combination of the oxygenation of wastewater in the PVA gel tank and the anoxic conditions in the following tank works to remove most of the ammoniacal nitrogen from the wastewater as nitrogen gas. With the introduction of PVA gel, existing systems can be modified to treat 2-5 times the existing BOD and COD loading using the same footprint. They offer both containerised and non-containerised systems using PVA gel technology. The capacity of the systems can range from a minimum of 10 KLD to 2 MLD. Aqua-K are based in Paerata, South Auckland, where they are operating a 30 KLD containerised wastewater treatment demonstration plant showcasing their treatment capability. Their system is currently treating the waste from a mix of industrial and domestic sources. They have recently begun building a containerised system with a capacity of 150 KLD to demonstrate the system’s capabilities treating municipal sewage and wastewater. Aqua-K can provide tailor-made designs, drawings and engineering solutions to treat your wastewater. Contact us and arrange a visit to get a demonstration of this exciting new technology.

Aqua-K can also provide other wastewater treatment components, including: Toray MBR modules Reverse Osmosis filtration systems Mitsubishi MBR modules UV filtration systems “Aqua-K typically expects a 70-80% reduction in sludge production over an existing system by using the PVA gel as part of the treatment process. We’ve seen a particular interest in this feature, with various councils and industries facing huge sludge transportation and disposal costs.” - Peter McLeod, Director, Aqua-K NZ Ltd. 12/07/22 1:51 PM The PVA gel beads contain a network of tiny pores, about 20 microns in diameter.
