Fibreglass Sand Filter

sand filter


A filter used in water purification and consisting of layers of sand arranged with coarseness of texture increasing downward


The oldest and most basic filtration process, which generally uses two grades of sand (coarse and fine) for turbidity removal or as a first stage roughing filter or pre-filter in more complex processing systems.


Sand filters are used for water purification. There are three main types; # rapid (gravity) sand filters # upflow sand filters # slow sand filters


(sand filters) Devices that remove some suspended solids from sewage. Air and bacteria decompose additional wastes filtering through the sand so that cleaner water drains from the bed.

fibreglass


fiberglass: a covering material made of glass fibers in resins


silica based glass extruded into fibers that possess a length at least 1000 times greater than their width; a composite material made from fine fibres of spun glass held together with resin. (Also called Glass-Reinforced Plastic.)


frames are relatively new. They are light, durable and strong, even in narrow sizes, they have excellent insulating qualities, and they do not expand and contract with heat and cold as much as other frames. They are also more expensive than other types of windows.
