Alt-Tek Water Filtration

The removal of solids from water can be a complicated process.  There are a multitude of different filtration methods to choose from.

AMES water treatment team has considerable experience in choosing the correct method of solids removal for each application.

Alt-Tek is one method of suspended solids removal that has particular use in water treatment.

Alt-Tek Filters have proven to be an optimal solution for the removal of a variety of deposits from cooling systems, closed system heating and chilled water circuits.

How They Work
Driven by the inlet pressure, the water or liquid with particles enters the top chamber at a tangent, causing rapid rotation and acceleration through the tangential slots/holes in the top section of the separator, down into the centre section.

The rotation of the liquid forms a vortex in the centre of the separator with the centrifugal force, causing separation of the heavy particles from the liquid. The separated particles accumulate in the bottom collection chamber from which they are purged.


Advantages Of Alt-Tek Filtration

  • No Moving Parts
  • No Filter Elements, Screens, Bags Or Media
  • No Cleaning Costs
  • No Down Time – Continuous Filtration
  • Low Water Loss When Purging
  • Low Pressure Loss
  • No Backwash


High Performance Cyclone Separators

They continually remove suspended solids down to less than 20 micron in size from the cooling tower sumps

The accumulated dirt is automatically purged to drainage without backwashing and without interruption filtration. This approach also uses minimal water.


Benefits

  • Reduce corrosion by keeping internal surfaces clean and free of debris, allowing inhibitors unimpeded access to protect the metal surfaces
  • Reduces erosion by removing suspended solids, which cause surface erosion of pumps and equipment
  • Reduces chemical treatment costs by removing suspended matter and reducing dosage of corrosion inhibitors, biocides and dispersants required to maintain water quality
  • Reduces the risk of Legionella by preventing sludge and silt deposits which harbour and encourage the growth of bacteria and reduce biocide effectiveness
  • Improves dispersant performance and reduces scale formation by removing precipitated hardness salts, allowing dispersants to be effective
  • Continuous filtration with no change in pressure loss – can be used in mainstream flow. No variation in pressure loss or flow rate is experienced as dirt and debris are collected and removed from the water flow.
  • No backwash required – filtered dirt is purged to drain with minimum water loss whilst service flow is maintained
  • Zero water loss option when fitted with closed recovery dirt collector the unit will operate with no system water loss, ideally suited to glycol and brine systems. Allows visual inspection of the dirt and debris removed
  • Compact, easily installed – can normally be fitted as sidestream filter using existing connections. High filtration with minimal plantroom are required
