Crystal Sands Filter Vessels

Crystal Sands Media is a glass-based filtration media used for removing sediment, dirt, rust, and other large particles. 

The Crystal Sands works very much like standard silica sand, filtering sediment out of the water. However, unlike silica sand which should be replaced every 3 to 5 years, Crystal Sand Filter Media can last up to 10 years. 

The smoother surface of the Crystal Sands also means that it is harder for bacteria to grow, which helps to extend the life span of the media.

Please note that the Crystal Sands Filter Vessels will filter to around 100 Micron only, if you require a finer level of sediment/particle filtration then we would recommend looking at some of the alternative filtration options we have available such as Arkal Disc Filters (55/20 Micron), or AFM® Activated Glass Media Vessels, or Bag Filters.  

Crystal Sands is Eco-Friendly being made of 100% recycled crushed glass. 

Crystal Sands is a perfect mix of grain size to optimize filtration flow and backwash fluidization. 

The Crystal Sands Media Comes in 18kg (13l) bags. Two bags of Crystal Sands Media has roughly the sand as one 40kg bag of Silica Sand Media. 

Key Benefits: 

• The backwash is more efficient - Crystal Sands is lighter than silica sand, fluidizing faster, using less time, energy, and water. 

• Safer - Crystal Sands is not susceptible to metal leaching under acidic conditions as it does not contain high levels of heavy metals such as chrome, iron cobalt, and other metals conventionally used to color beer and wine glass bottles. 

• Recycled Materials - Crystal Sands is environmentally friendly, versus the mining of silica sand, relieving landfill sites of waste. 

• Chlorine Consumption is lower - due to fewer secondary chlorine reaction products such as chloramines. 

• Increased water purity and lower turbidity - Crystal Sands has a reduced filtration period (by up to 25%) with an ionically charged and higher surface area than silica sand, collecting debris, and microbial particles as small as 10 microns. 

• Up to 20% saving in weight compared to Silica Sand 

• Longer lasting - Crystal Sands replacement period is well over 10 years. It has a lower propensity to fracture and wear than Silica Sand. 

• Lower incidence of biofilm - Crystal Sands is not Susceptible to bacterial colonization.

Crystal Sand Filter Vessel Normal Operation and Backwashing

During Normal, operation water flows into the top of the vessel and travels all the way to the bottom of the vessel. As the water flows down through the vessel, all the particles, rust, dirt, mud, and other sediment is captured between the filter sand granules. The water then enters the bottom strainer, flows up the riser pipe, and out the top of the vessel. 

Valve Head Options 

Manual Valve Head

• Does not require any power. 
• Backwashing must be done manually.

Automatic Valve

• Requires an electrical source to operate (requires a normal 2 pin or 3 pins plug)
• Can be set to automatically backwash the vessel, with either fleck or digital time. 
• Please note the Automatic valve will either be a fleck or digital valve, depending on stock availability. A manual for programming the valve head will be provided with the unit. 

How to install the Deep Bed Sand Filter Vessel
