water purification

With the ever-increasing population and numerous droughts, as well as various sources of water pollution, the provision of safe and sanitary water is one of the most important challenges facing mankind today, as the World Health Organization has stated that it is the cause of one of ten diseases and also the cause of six percent of death. And the deaths are on average due to the lack of access to healthy and safe water sources.

The main water pollutants include the following:

1- Solid and suspended materials

2- Anions such as fluorine, arsenate, chlorine

3- Cations such as iron, manganese, chromium, arsenic, mercury, cadmium, etc

4- Organic substances and humic acid

5- Microorganisms include all kinds of bacteria, viruses, parasites and fungi

6- Types of gases such as ammonia, carbon dioxide, hydrogen sulfide

7- Harmful chemical compounds

Zeolite-clinoptilolite due to its valuable features such as high cation exchange capacity, specific surface area and extensive surface absorption, porous structure with nanometer holes suitable for absorbing many materials and gases, as well as reasonable price and complete compatibility with the environment and the possibility of simple regeneration are among the materials that They have shown their abilities in the field of water purification and are used in some European countries, America and Australia.

The benefits of using zeolite
Mechanical filter and molecular sieve of solid materials and suspended particles
Reducing water hardness through the absorption of calcium and magnesium ions

Adsorption of various cations due to high cation exchange capacity, the sequence of adsorption of heavy metal cations by clinoptiolite Pb2+> Cd2+>Cu2+> Co2 +> Cr2 +> Zn2 +> Mn2 +> Hg2

Absorption of various anions such as fluorine, nitrate by surface absorption and anion exchange. The sequence of anions absorption by clinoptilolite SO42-> I-> NO3-> HCrO4-> Br-> Cl-> OH-
Destruction of microorganisms and surface absorption of microorganisms killed by chlorine
Adsorption of organic matter and humic acids through surface adsorption
Absorbing some gases such as ammonia and hydrogen sulfide and improving the taste and smell of water
Absorption of some poisons and chemical fertilizers
Aquarium and fish and shrimp breeding ponds

The two main issues in ponds and aquariums are oxygen and ammonia. Ammonia concentrations are often more difficult to control. Ammonia concentration should increase through urine, feces and fish food residue. This gas dissolves in water and produces ammonium ions, which are toxic to aquatic life. Accumulation of this substance prevents oxygen delivery by hemoglobin and increases the mortality rate in young fish.

Zeolite-clinoptilolite has a unique ability to absorb ammonium ions. In addition, zeolite reduces ammonia production by mechanical filtering and absorption of food residues. The ability to absorb ammonium by different clinoptilolites is different and depends on various factors such as the degree of purity of clinoptilolite, its cation exchange capacity and the type of dominant cation. Clinos with higher purity, higher cation exchange capacity, and potassium type show a higher ability to absorb ammonium. Another problem of this industry is the amount of heavy metals and harmful substances that may be present in aquatic food, and zeolite plays an important role in this field due to its absorption properties, molecular sieve and cation exchange capacity.

Swimming pools

Contrary to popular belief, the unpleasant smell in swimming pools, redness and inflammation of the eyes, as well as sensitivity and itching of the skin are not directly related to the consumption of free chlorine, but are often due to the presence of chloramines, which are actually a combination of urea and other nitrogenous compounds in the water. They arise with free chlorine. Organic substances such as skin, hair and urine of swimmers are the factors that create nitrogenous compounds. Common water purification methods, including silica sand filters, actually separate suspended and solid water particles. Zeolite-clinoptilolite has a very high ability to absorb ammonium and nitrogen ions and reduce the formation of chloramines, which are very problematic. By reducing the formation of chloramines, chlorine consumption is also reduced, and as a result, chlorination costs are also reduced. The ability to absorb suspended particles on the surface as well as the mechanical filter, along with the low price and being lighter than the normal sand used in swimming pools, this mineral can be easily replaced with this material.

The benefits of using zeolite in swimming pools

1- Reducing the amount of ammonium and nitrogen compounds and chloroamine, which is the main cause of bad smell and causing skin and eye allergies.

2- Mechanical filter of suspended particles

3- Reducing the cost of chlorination due to reducing the consumption of chlorine to form chloramines

4- Toughness

5- Being light and cheap

The company’s products for water purification purposes are produced and presented in two normal and combined sections:

The production process in the first part includes the selection of zeolite minerals suitable for general consumption or any type of purification consumption (depending on the purpose of purification) and then crushing and granulation, heat treatment and packaging.
The second part includes the production of special products that are obtained by combining special materials with special zeolites selected and separated in special chemical and thermal conditions. This operation is performed for cases where purification is done purposefully to remove specific pollution
