Answer: Flow rate is the most important factor in determining SandMaster Separator size because all LAKOS Separators operate within a prescribed flow range. Pipe size is not a factor in model selection so do not use your existing pipe size to determine the separator size.

Required separator size is often, but not always, smaller than the existing piping, and appropriate hardware is used to match the inlet/outlet size with existing piping.

Answer: To determine the necessary purge frequency, purge often at first and calculate the proper rate based on the expected volume of separated solids. Purge duration should be long enough to evacuate the purge chamber AND clear the entire length of the purge piping of all solids. This is usually indicated by a change in the color of the purged liquid from dark to light.

The time between purges should never exceed the time it takes to fill 1/3 of the collection chamber volume, based on the expected solids load and the separator’s purge collection volume, as indicated in the separator’s literature. Refer to LS-608 for additional information on calculating purge frequency and duration.

Answer: While there are many LAKOS Separators still in service after 15-25 years, there are many variables to the longevity of a LAKOS Separator. It can generally be expected to last as long as any other materials of similar construction in that system. Environment, fluid chemical make-up, flow, the material of construction, type of solids, and maintenance purging are all important factors to the life of a separator. It is important to consider all these factors when purchasing a separator. Providing LAKOS with details about your application will ensure your separator meets or exceeds the life expected through your purchase. Consult ADTEC technicians to obtain the life expectancy in your specific application.

Answer:  Solids-removal efficiency is affected by several factors, including the difference in specific gravity between the solids and the carrying liquid, the viscosity of the liquid, the particle shape, and any purging enhancement techniques. In general, with a specific gravity ratio of 2.6 (e.g. quartz sand in freshwater), liquids of 1 mPas viscosity, and generally round particles, a single pass through a separator removes up to 98% of particles 74 microns (0.0029 inches) and larger. Appreciable quantities of particles finer than 74 microns are also removed, as well as particles of lighter specific gravity.

Higher specific gravities (like mill scale in water, where SG=5.7) result in much finer levels of filtration.

Contact LAKOS for assistance determining performance expectations on your specific application.

Answer:  The maximum solids loading on LAKOS Separators is recommended to be less than 1% by volume. While 1% may seem low, keep in mind that 1% in a small 10 m³/h  system is 100 liters of solids every hour, or 2400 Liters (Twelve 55-gallon drums) of solids per day.

SMP Separators for residential use are not recommended to exceed 0.25% by volume. ILB/ILS Separators are not recommended to exceed 0.50% by volume. If your application exceeds these limitations, please consult your factory representative for proven alternatives.
