About Hydro-Pure Technology
A team of scientists from Qian Hu and a local research company have scored a first by jointly developing the revolutionary Hydro-Pure technology that is capable of enhancing the natural filtration process in aquariums by as much as a few hundred percent when compared to conventional systems.
This energy efficient Hydro-Pure Technology is eco-friendly and truly the first of its kind in the world. It can also be applied to other areas in the ornamental fish industry as it promotes a natural, chemical free environment for all aquatic creatures.
The process not only provides a more efficient pathway for the degradation of aquarium waste, it also makes sure that the by-products are safe and the energy consumption is kept to a minimum.
The technique aims at the use of very low electric current to produce “OH-” reactive ions which quickly break up bio-loads into nitrogen gas, water and smaller organic and inorganic ions through oxidation. The process involved is not to be compared to other electrolysis techniques which use very high energy consumption; it is much less intrusive, simple and low cost.
The trick is in the specially formulated medium which catalyses the whole degradation process without the need of high current.
With Hydro-Pure Technology, coupled with natural bio-filtration, the water in the aquarium will be more stable and also more resistant to nutrient surges (eg Ammonia) which are detrimental to fish.
The effect of the technology is shown in improved water quality, healthier fish with more vibrant colour, faster growth as well as enhanced maturity.
This technology is currently the most innovative, environmentally friendly system available in the aquarium industry.
