water treatment

ZEO-KLER is extracted from clinoptilolite, a naturally occurring zeolite mineral for use in water treatment applications, crushed, sieved and chemically regenerated. ZEO-KLER is a completely natural zeolite with large internal void volume and high surface area that can effectively filter clay and colloidal particles. 

• Zeolites are natural minerals formed millions of years ago. Its physical retention of particles and molecular sieve of contaminants indicates that zeolite is a very good filtration medium and produces a very clear water compared to quartz sand.

•The porous structure of zeolite is very suitable for ion exchange, molecular sieving, absorption, adsorption and filtration processes in water. It is physically and chemically stable over a wide temperature and pH range.


ZEO-KLER is an all-natural zeolite with a high surface area and a large internal space that can effectively filter clay and colloidal particles. Pressure drop in clean environment is less than typical silica sand.

• Particle Size: 0.5 mm -2.00 mm 1.0 mm-4.0 mm

• Form Factor: 1.64

• Effective Size: 0.55 mm

• Form Factor: 0.68

• Wet Particle Density: 1,800 grams / liter

• Abrasion, ASTM C-13:> 20, degrees C, @ 500 cycles.


• Your pool always stays bright

• Provides savings in water, energy, labor and chemicals

• It can be used instead of quartz in all sand filters (fast and slow types)

• It reduces operating costs

• It reduces reverse washing by 50%

• Reduces chloramines, odor and eye burning

• It is completely natural

ZEO-KLER is also used to reduce the formation of chloramine (bound chlorine) in pool water. ZEO-KLER is a surfactant molecular sieve that traps ammonium ions and disrupts the normal cycle of bound chlorine formation.


A pool filtered with ZEO-KLER will remain active for a longer period of time until break point chlorination than that filtered with quartz sand. The result will not be negative conditions such as chloramine odor, red eyes, skin redness and swimsuit bleaching.


It will be sufficient to regenerate the ZEO-KLER with brine once during the operation period of two or three months, since ammonium ions are removed from the water environment during each shock of the pool.



• '' We got cleaner water in 3 days. We now have backwashing in our pool every 3 weeks, not every 2-3 days. Also, the bonded chlorine turns out to be 0.3 ppm or less ''

• '' We replaced the quartz sand in the filters with Zeo-Kler. Our pool is surrounded by trees and therefore we used to have a pollution problem in the pool water. After replacing it with Zeo-Kler the water became very clear. We do backwash only once a month. The pH remains constant and we do not do shock chlorination ''


Nitrogen compounds and heavy metal ions found in domestic and industrial wastewater pollute underground and surface waters in the environments where they are discharged and destroy the characteristics of these environments as both clean water and utility water. In addition, it has a toxic effect on fish and other aquatic fauna living in these waters and prevents the reproduction of algae necessary for this fauna to feed.

ZEO-KLER can keep contaminants in water up to 3 microns with its highly porous structure. It has inherent negative charges that enable it to adsorb cations such as ammonium and heavy metals. It also has the capacity to absorb some organic contaminants and unwanted odors. ZEO-KLER particles also attract bacterial flocks, increasing bacterial activity per unit volume. Under favorable conditions, cations originating from various industries can be removed with ZEO-KLER:

Rb + Li + K + Cs + NH + 4

Na + Ag + Cd + 2 Pb + 2 Zn + 2

Ba + 2 Sr + 2 Cu + 2 Ca + 2 Hg + 2

Mg + 2 Fe + 3 Co + 3 Al + 3 Cr + 3

Examples of industrial wastewater using ZEO-KLER:

• Electroplating Wastewater (Nickel and Galvanized)

• Mineral Processing Wastewater

• Textile Industry Wastewater

• Paint Industry Wastewater

• Glass Industry Wastewater

• Battery Industry Wastewater

• Photo Wastewater


• Increase in system capacity reduces the initial investment cost and operating costs

• Getting better quality effluent provides better protection to the receiving environment

• Since less chemicals will be dosed for nutrient removal, operating costs are reduced

• Improvement in sludge characteristics increases the reuse possibilities of sludge

• Sludge removal costs are reduced as sludge dewatering is better

• Decreasing the need for polyelectrolyte required for sludge dewatering provides a reduction in chemical substance costs


ZEO-KLER is used for water preparation and cleaning for drinking and process water. The use of ZEO-KLER in pre-water filtration and treatment is very important due to its ability to perform many functions at the same time. ZEO-KLER is highly advantageous because processes such as mechanical filtration, ion exchange, easy maintenance and regeneration are performed at low costs.

ZEO-KLER is much more effective compared to standard filter media (quartz and anthracite) due to its enhanced surface porosity granules. With the use of ZEO-KLER, the flow rate increases and the pressure drop decreases. In parallel with mechanical filtration, the ZEO-KLER surface, which is active according to its sorption and catalytic properties, is affected by the organic matter in the water, inactivating and oxidizing the organic matter.

ZEO-KLER is capable of adsorbing cations such as iron, ammonia, manganese, potassium, calcium, magnesium, and its adsorption rates vary depending on the concentration of cations, flow rates and pH.

Softening the water is one of the important things ZEO-KLER does. It softens the water by replacing calcium and magnesium ions that create hardness in water with sodium ions.

Due to its ion exchange feature, ZEO-KLER is used in the decontamination of some cations in water. Our natural chemically regenerated zeolite for use in water treatment processes can control the ammonia content in the water. ZEO-KLER shows the following order of selectivity in ion exchange processes:

Cs + - Tl +> Rb +> K +> NH4 +> Na +> Ba2 + - Pb +> Sr2 +> Ca2 +> Mg2 +

At the same time, Hg2 +, Ag +, Cu2 +, Cd2 +, Co2 + ‘are also located on the left side of the row due to their efficient extraction from the purified waters.
