ZEOSORB
INTRODUCTION
ZEOSORB® has been introduced to the process purification of drinking water and wastewater due to its large specific surface area and the selective adsorption of substances, such as ammonia, dissolved organic matter and many other cations. Moreover, ZEOSORB® has advantageous hydraulic properties, that is the filtration capacity of large quantities of water. Compared with other adsorbents, ZEOSORB® is more stable, has better filter features, accessible and relatively cheaper.
APPLICATIONS
ZEOSORB
Based on numerous studies, it can be concluded that ZEOSORB® has great potential as an effective adsorbent in numerous processes of purification of drinking water and wastewater, such as water softening, removal of ammonia (from municipal wastewater, wastewater from livestock farms, barn manure, water from ponds and swimming pools, removal of nitrogen, removal of dissolved organic matter and color, removal of heavy metals (from natural water, acid mine water, industrial wastewater), removal of radioactive substances from wastewater, desalination seawater and many others. ZEOSORB® performs as a polyfunctional sorbent in the wastewater treatment process and it binds several harmful components. However, it does not possess the ability of anions adsorption due to the negative charge of its aluminosilicate network. Superficial modification of ZEOSORB®, by means of organic modifiers, allows partial neutralization of negative charge of the external surface of ZEOSORB® media.
Physical filtration barriers for accumulation or collection of microorganisms in the water that endanger human health have been in focus during the last several years. ZEOSORB® will be an ideal collector of pathogens such as giardia, cryptosporidium and other bacteria and their spores. Most of these organisms and their spores are in the size range of 0.5 – 10 micrometers (microns). In contrast, the water-permeable pores in ZEOSORB® are mostly smaller than .05 microns; therefore the ZEOSORB® fragment or granule can “surface collect” a high percentage of these microorganisms while the water passes through the ZEOSORB® fragment. All drinking water standards for microorganism pathogens and turbidity can be most easily met using a natural, relatively low-cost material, such as ZEOSORB® rather than “sand” which is chiefly quartz grains.

QUESTIONS
ZEOSORB® is a high-purity, natural aluminosilicate (zeolite) mineral filter media manufactured by Watch Water GmbH in Germany. It is engineered for superior filtration and adsorption in a wide range of water treatment applications, from municipal wastewater to industrial process water.
Its extremely high surface area (>270 m²/g) and microporous structure allow it to physically filter particles down to <3 microns and adsorb contaminants like ammonia, heavy metals, and dissolved organic matter.
ZEOSORB® is available in two main grain sizes: 0.6 – 1.5 mm (18×35 Mesh) and 1.5 – 2.5 mm (14×30 Mesh).
ZEOSORB® is a complete replacement, offering:
- Much finer nominal filtration (< 3 µm vs. 12–20 µm)
- Higher flow rates (15–48 m/h)
- Significantly greater solids loading capacity (~2.6×)
- Fewer backwash cycles and lower backwash water demand
- Finer filtration and better water clarity
- Higher service flow rates
- Reduced backwash cycles and water use
- Longer media life (~10 years)
- Lower operating costs
- Ability to double plant capacity without expanding footprint
ZEOSORB® effectively removes ammonia from water (e.g., municipal wastewater, farm effluent, pools). Once saturdated, regeneration could be performed with Sodium or Potassium.
ZEOSORB® can operate at very high service flow rates, typically between 15 and 48 m/h, depending on the application. This is significantly higher than the 15–17 m/h typical of sand/anthracite systems.
Thanks to its high loading capacity, ZEOSORB® requires about half as many backwash cycles compared to sand/anthracite. Recommended backwash velocity: 25–50 m/h.
Yes. ZEOSORB® is certified to NSF/ANSI/CAN 61 (drinking water system components) and NSF/ANSI/CAN 372 (lead content). It is also listed under the German Drinking Water Ordinance (TrinkwV 2011) and classified as a GRAS product.
Yes. ZEOSORB® is a naturally mined mineral and safe for use in drinking water applications. Available certification from Water Quality Association (WQA) and The International Association of Plumbing and Mechanical Officials (IAPMO).
Under most conditions, spent ZEOSORB® can be reused as a soil amendment for lawns and gardens, simplifying disposal.
- RO and UF pre-filtration
- Pre-filter for Granulated Activated Carbon (GAC)
- Cooling tower make-up water filtration
- Produced water treatment for reuse
- Removal of ammonia, heavy metals, and turbidity
- Municipal and industrial water treatment
Yes. ZEOSORB® is highly effective at reducing SDI, an important RO pre-treatment metric, far outperforming multimedia filters.
The anticipated filter bed life for ZEOSORB® is about 10 years.
- 25 kg bags (30 L) – 40 bags per pallet (~1025 kg gross)
- 1000 kg bulk bags (1200 L) – 1 per pallet (~1025 kg gross) Other packaging available on request.
ZEOSORB® is manufactured by Watch Water GmbH, Mannheim, Germany.
