Arkal Disc Filters
Arkal Disc Filters are washable pre-filters that will extend the life of the filters that follow it. If your water is visibly dirty then adding a disc filter as a first stage is highly recommended.
Disc Filtration Technology
Arkal Water Filtration Systems operate using a specially designed disc filtration technology. Thin, color-coded polypropylene discs are diagonally grooved on both sides to specific micron size. A series of these discs are then stacked and compressed on a specially designed spine. When stacked, the groove on top runs opposite to the groove below, creating a filtration element with a statistically significant series of valleys and traps for solids. The stack is enclosed in a corrosion and pressure resistant housing.
During the filtration process, the filtration discs are tightly compressed together by the spring's power and the differential pressure, thus providing high filtration efficiency. Filtration occurs while water is percolating from the peripheral end to the core of the element. Depending on the micron rating, there are from 18 (in 400-micron discs) to 32 (in 20-micron discs) stopping points in each track, thus creating the unique in-depth filtration.
Benefits:
Keep in mind:
The disc filter does not filter the water finely enough for bacteria or heavy metals
The disc filters are brought in as needed, as a result, there is a lead time of typically 5 to 15 working days before the Disc Filters will be ready for collection or delivery.

With treating water you normally need quite a few different components working together. This product is just one of those components and most likely will not be enough on its own. We have a team of experts that can advise you on what you need to get your water to a good quality. Alternatively, our Borehole Water Section is a good place to start as it has videos explaining the various areas that normally needs to be addressed to treat water.
PVC Threaded and Glue Fittings
PVC(Polyvinyl chloride) fittings are used to connect sections of pipes or tubes, adapt to different sizes or shapes, and controlling the flow of water. There are two predominant types of PVC fittings namely PVC Glue Fittings and PVC Threaded Fittings. The difference between the two is that PVC Glue Fittings result in permanent joints and PVC Threaded Fittings are semi-permanent and can be replaced. PVC Glue fittings are joined with primer and cement- a chemical solvent that melts the surface of the PVC and then quickly re-hardens to fuse the pieces together. This results in an airtight, leak-proof bond similar to what you get with welding metal. An example of such a fitting is a PVC Glue Reducing Socket which is used to join together two pieces of PVC pipes with different diameters. Another example would be a 90 Degree Elbow which is used to connect two pipes of the same diameter at an angle of 90 degrees.PVC Threaded fittings utilise a simple threaded connection whereby replaceable 'male threaded' are screwed into 'female threaded'.Male threads have a thread on the outside of the fitting and female threads have a thread on the inside. When you thread the fitting in, it compresses against the other threads.PTFE tape is used to thread these together and the proper way to assemble threaded fittings is to finger tighten, then add one to two turns but no more. An example of a threaded fitting is a Reducing Nipple Male Threaded which is used to connect between two female threads of different diameters.
