What is Harborlite used for?

What is Harborlite used for?

Harborlite® is a thermally expanded perlite widely used in adhesive and sealants to impart weight reduction, improve insulation, mechanical strength and hardness.

What is Harborlite perlite?

Harborlite Perlite is a high porosity filter media that is manufactured from perlite ore, which is an igneous mineral. When Harborlite Perlite is applied to the filter septum, it forms a low-density, highly porous filter cake that is ideal for separation in high solids applications.

How much perlite do I put in a pool filter?

The Journal of Environment Engineering concluded that adding 1.2kg/m2 (0.25lb/ft.) of perlite to a sand filter significantly improved the removal of 5-um microspheres. Previous research indicated that these microspheres serve as a reasonable surrogate for Cryptosporidium Oocysts in pool water.

Is perlite better than DE?

Perlite is so lightweight, that only half the amount of DE powder is needed. Proponents of Perlite say that the light weight results in less bridging between grids, more complete backwashes and longer filter cycles, as compared to DE powder.

Is perlite the same as diatomaceous earth?

Diatomite is a soft powdery mineral resembling chalk and distinguished by a variety of shapes. Particle size removal is virtually identical using Perlite instead of D.E. The major advantages of Perlite over D.E. are handling, disposal and health risks.

Is cellulose fiber better than DE?

Compared to DE’s ability to filter down to 4 to 5 microns, cellulose fiber will filter to about 2, providing pool owners with “better than 100 percent finer filtration,” says Gene Fields, president, Greenfield Products, Santa Ana, Calif. “It will of course give you much more clarity in the water.”

Is there a substitute for diatomaceous earth?

Dicalite’s DicaPOOL Perlite Filter Powder is a direct replacement for other diatomaceous earth swimming pool filter powders. As a safe alternative for all Diatomaceous Earth filters, Perlite filter aids can weigh as much as 50% less than the other types of filter media. So 1/2 lb. of Perlite is equal to 1lb.

What can I use instead of Diatomaceous Earth?

cellulose fiber. This biodegradable, nontoxic and renewable product is quickly becoming the go-to product for superior filtration and water clarity. One of the best known cellulose fiber products is Fiber Clear. Fiber Clear is an environmentally-safe alternative to Diatomaceous Earth for use in D.E. Pool Filters.

When should you backwash a DE filter?

Bottom line, the filter must be backwashed on a regular basis to ensure that your pool water is clear. “When do we need to backwash?” – It is recommended to backwash your filter once every 4-6 weeks of regular use.

Is perlite the same as Diatomaceous Earth?

Which is better sand filter or DE filter?

Sand filters are least effective but also the least expensive to buy and use. Cartridge filters are more effective but are more expensive to buy and use. DE filters are the most effective but are the most expensive to buy and use.
