Tower Water is not a chemical company. We are a solutions company. We always choose the best solution to a concern or a problem.
We have partnered with Diamond Water Systems, Inc., to provide the best quality in high performance filtration systems. Click here for more information on Diamond Water filtration.
Filtration Beats Chemicals
Tower Water believes a mechanical solution is superior to a chemical solution in virtually every instance. Tower Water provides and maintains filtration assemblies of all types for all water applications. The correct filtering system from Tower Water is designed and based on:
- Particle Size
- Quantity of Particles
- Location and ease of installation
- Water pressure
TYPES OF FILTRATION AVAILABLE
Multimedia Sand Filtration (0.25 – 5 Micron)
This filter is similar to a single-media filter, except that it maintains a minimum of three different stratified layers of filtration media, starting with gravel and working up to an ultra-fine base. Suspended solids are trapped at the top layer of media and are back-washed regularly either by time or a pressure differential. These vessels generally backwash frequently at first, but eventually maintain an excellent water quality in the system they are installed in. They are generally piped before a critical piece of equipment and are almost always back-washed with city water. They normally consume up to 5% of the flow in series, so that they never affect the flow-rate of the water system itself. These filters are ideal for data centers and other critical process and HVAC systems. These filters produce a substantial return on investment based on energy, efficiency and water savings.
Single Media Sand Filtration (greater than 5 Microns)
This filter is very similar to a pool filter, where a sample of the system water is dispersed over a sand filter media. As the media becomes coated with suspended solids, the pressure differential rises and the filter goes into a backwash and the particles are discharged to drain. Backwash should always be completed with city water unless unavailable, and system water must be used. Single Media Sand Filtration is ideal for non-critical, open and closed loop systems, and for swimming pools.
Cartridge Filtration (0.5 to 150 Microns)
This is very similar to the bag filtration, except that a cartridge is used in place of a bag. Cartridges by design maintain more surface area than bags which allows for quicker filtration and greater capacity. However, flow rate is reduced due to a sometimes severe pressure drop. Cartridges also have some limitations in Hot Water systems. This filter is ideal for a cleanup scenario where a high-micron filter is used, and gradually reduced to a fine-micron, maintenance filter. It is used almost exclusively in closed loops and potable water.
Bag Filtration (0.5 to 200 Microns)
As the name suggests, bag filters send water through a bag. Particles of a magnitude of size get caught in the bag. This type of filter has a higher velocity that can flow through the surface area of the vessel and the bag. Bags are generally inexpensive and sometimes cleanable. This filter works well with a clean-up scenario, where the vessel starts with a high-micron bag catching all the very large particles. As the large particles are removed, smaller and smaller bags are used until the water is of a desired quality. These filters are designed for closed loops and potable water systems where new loading is known and minimal.
Cyclonic Separators (greater than 50 Microns)
These devices remove particulate by utilizing a spinning chamber in which particles fall into the chamber and are eventually put through a bag filter or discharged through a bleed valve to drain. These particles are generally large and greater than 50 Microns. These separators are used on open water systems where the most heavy loading occurs.
Domestic Filtration (less than 5 Micron)
Normally domestic or potable water filters are cartridge or bag type. The pore or micron size is usually very small (5 microns or less) and designed to remove nearly 95% of the water’s contaminants. This filter may also contain elements of carbon to remove organics and improve taste. It may have an element of silver or ultraviolet light to destroy bacteria that may come in through a city source or a well.
