Zeolite is environmentally and economically acceptable hydrated aluminosilicate materials with exceptional ion-exchange and sorption properties. Their effectiveness in different technological processes depends on their physical-chemical properties that are tightly connected to their geological deposits. The unique tree-dimensional porous structure gives it various application possibilities.
Application:
Due to the excellent properties of zeolites, it has been widely used in the following fields:
Pool Filtration
It dramatically reduces pool odour and eye and skin irritation by markedly reducing chloramine formation.Via a greater dirt retention capacity it results in far fewer backwashing cycles and a far longer product viability lifespan – making it more environmentally friendly and more friendly on your savings!It also offers a water clarity (via better filtration) far superior to alternative medias which makes for a much more aesthetically pleasing pool…
Water Treatment and Enhanced Wastewater Purification
Zeolite provides a process for the enhancement of wastewater purification systems which utilises the unusual properties of zeolite to improve the performance and/or capacity of existing treatment systems, or to reduce capital expenditure on new treatment systems. It offers exciting possibilities for improvements to, and cost savings for, municipal wastewater treatment systems. It should be emphasised however that these advantages are not just limited to municipal systems. It is equally applicable to many industrial situations.
From an environmental point of view zeolite offers a low cost, easy to implement, means of providing enhanced environmental protection. It offers greater system capacity, reduced odour both during treatment and in subsequent sludge reuse, and provides water protection from heavy metals. Further it reduces metal salt additions for phosphorus precipitation, and creates desirable characteristics for sludge reuse.
Aquaculture
Unique Properties, Unique Results
Most fish farms (and non-commercial fish storage) tend to use concrete or polyethylene tanks or unlined ponds. When tank storage methods are used all nutrient removal becomes costly as it must be done externally. Zeolite excells at sustainable, non-chemical, and cost effective filtration due to its unique properties.
- Reduces over stocking risks
- Removes need for biological filters (in most use cases)
- Removes ammonia without nitrate build up
Features of zeolite
Strong absorption
A large number of cavities and channels of the zeolite crystals make zeolite have very big specific surface area, and can form an electrostatic attraction with a special crystal structure, which has zeolite generate considerable stress field and strong absorption property (can replace the existing wood activated carbon) .
.
Ion exchange property
The positive ions like K +, N a +, Ca2 +, etc. in Zeolite are not very closely and tightly combined with the crystallized structure，and it has the property of reversibly exchange with other positive ions in an aqueous solution Therefore it is much easily to make exchange interaction with positive ions around.
Catalytic property
The catalytic property of zeolite is showed when some reaction substance is on the cavity surface of zeolite crystals, the reaction rate will accelerate, and the new substance formed by the reaction can be released and diffused from the zeolite inside, while ensure the zeolite crystalized structure not destroyed.And thus it has the catalytic property.
Molecular sieve
The channels and cavities in the zeolite have with precise and constant diameter under physical and chemical conditions, which can adsorb this substance with smaller diameter, and exclude those with larger diameter and therefore it can screen molecules.
Acid and alkali-resistance,high－temperature resist.
zeolite can react with a strong acid for two hours below 100℃with the crystal structure not destroyed; and it is stable in “aqua regia”.
