Conventional Systems

Granular activated carbon (GAC) is commonly used for removing organics & residual disinfectants in water supplies. This improves the taste of the source as well as minimizes health hazards.

Packaged Plants

Engineered packaged systems for the efficient treatment of a water source to required outlet quality, using conventional technologies.

Activated Carbon (AC) Filtration

It protects other water treatment units such as reverse osmosis membranes and ion exchange resins from possible damage due to oxidation or organic fouling.

Sand Filtration

Filtration is relied upon as a barrier to remove suspended and colloided material from drinking water produced from polluted surface water. The sand filters use a specialized media, which removes particles to approximately 5 – 20 microns. The media used is a granular filter media that outperforms conventional multimedia materials due to its unique structure, allowing particulate to penetrate into the filter bed to provide superior filtration at increased flow rates.

Sand Filter & Activated carbon system typically designed for:

  • Potable water production
  • Process water production
  • Waste water treatment
  • Tertiary treatment of sewage effluent (for re-use as irrigation, etc.)
  • Removal of chlorine in preparation of product water or RO feed water


Clarification is the removal of particles from water to make it clear by coagulation, flocculation and sedimentation.  Clarifiers or settlers are commonly used in the treatment of potable and waste waters.

Clarifiers form part of a conventional treatment process, either as a primary or secondary treatment, as might be the case with waste water treatment. Nanotech provides different types of clarifiers, which include containerized lamella settlers.

Clarifiers or settlers are tanks, designed and constructed with the means to enable continuous removal of solids from a feed stream.

Clarifiers are typically used as a single process step or as part of multiple process stream in:

  • Potable water production
  • Process water production
  • Waste and discharge water treatment
  • Secondary treatment of sewage effluent
