About

ZeoClin® is a high quality natural zeolite (clinoptilolite), especially selected for its high purity, low quartz and heavy metal content, and the robustness of its granules, making it the ideal choice for all applications.  

ZeoClin® is available in a wide range of sizes: <25 microns, <40 microns, <300 microns, 300-700 microns, 0.7-1.6mm,
1.6-3mm, 3-5mm,   5-9mm and 9-16mm.

Technical Background

Zeolites are a family of crystalline aluminosilicate minerals.  In common with other zeolites, ZeoClin® has a three dimensional cage-like structure consisting of SiO4 and AlO4 tetrahedra joined by shared oxygen atoms. The negative charges of the AlO4 units are balanced by the presence of exchangeable cations which can be readily displaced by other substances, particularly ammonium and metal ions. This is known as cation exchange, and it is the high cation exchange capacity (“CEC”) of ZeoClin® which provides many of its most useful properties.

Sports Pitch Installation, Renovation and Maintenance

ZeoClin® confers the following benefits:
 
  • Improves nutrient and fertiliser retention in the root zone
  • Granules absorb soluble nitrogen and potassium, reducing leaching of key nutrients
  • Porous granules increase aeration resulting in healthier turf
  • Improves germination rates
  • Helps protect against fertiliser scorch
  • Robust granules resist soil compaction
 
In addition, the use of ZeoClin® as a perch layer on top of course backfill when installing drainage systems will minimise the loss of nutrients to ground water, helping to reduce nitrogen pollution and eutrophication.

Manufacture of Slow Release Fertilisers

ZeoClin® is used in the manufacture of slow release fertilizers, helping to prevent the leaching of excess nutrients into watercourses, thus reducing problems such as nitrogen pollution and eutrophication, as well as reducing the quantity of fertiliser required.

Biogas Production by the Anaerobic Digestion of Organic Substrates

The production of Biogas, via the anaerobic digestion of organic substrates such as food waste and manure, is an increasingly important source of renewable energy.  Biogas is a mixture consisting primarily of methane and carbon dioxide; the methane fraction is purified for use as a fuel.  The decomposition of proteins produces ammonium ions which strongly inhibit the methanogenic bacteria in anaerobic digestion (AD) plants.  The addition of Zeolite significantly enhances methane production by absorbing ammonium ions.  Zeolite has also been shown to significantly reduce the accumulation of Volatile Fatty Acids (VFAs).  This is important because elevated levels of VFAs result in a reduced pH and toxic conditions in the reactor.  Zeolite also readily absorbs hydrogen sulphide and heavy metals, again positively influencing reactor productivity. 

Waste Water Treatment 

ZeoClin® is used to remove ammonia from effluents.  It also has good selectivity for several heavy metals.
