There are many corrosive materials in waste water, if use traditional metal material in wastewater treatment plant, metal will be easily corroded, then you have to replace it regularly. As a result, the cost for processing waste water will increase. So more and more wastewater treatment plants start to use specialized FRP gratings.
Compared with metal grating, FRP grating for wastewater treatment plant has the character of light weight, high strength and corrosion resistance. It can solve corrosion problem thoroughly. There are many types of FRP gratings in wastewater treatment plants. The general mesh gratings(38×38mm) are mainly used to remove floating objects in the water, and the mini mesh gratings(19×19/38×38mm) are mainly used to remove some fine particles and suspended solids in the water.
|Available Panel Size||1220×4000/1524×4000/1220×3660/1220×4000mm|
|Mesh Size||38×38mm(General model)
19×19/38×38mm(Mini mesh, double layer)
|Raw Material||Resin(The type of resin needs to be adjusted according to the use environment to enhance the corrosion resistance of gratings)Aluminum Hydroxide
◇ FRP operation platform under the cooling tower
It has the characters of corrosion resistance, no need painting, no maintenance, light in weight, long service life. It is a good material for operation platform.
◇ FRP grating walkway
There are many walkways in wastewater treatment plant for routing inspection, they are usually welded by steel round pipe, due to corrosion they will need anti-corrosion painting every year. If use FRP to make walkways, it will make walkways stay long term colorful, and light constructed.
◇ FRP trench cover
There is corrosive liquid in trench, traditional trench covers are not corrosion resistant, and will be damaged in several years, or even several months, which makes the workshop such a mess. While using FRP gratings will solve the corrosion problem, and will be easy to leak waste water into trench, and easy to observe the conditions in the trenches.
◇ The biochemical filler support/hanging fixture for biochemical water treatment pool.
In the aspect of sewage treatment, it can be used as rack to treat domestic sewage.
◆ The woven glass fiber fully saturated with resin, makes grating has good corrosion resistance.
◆ The glossy surface and inclined grad make FRP grating has self-cleaning ability.
◆ Use molded FRP grating to distribute load evenly, will conductive to uniform distribution of grating installation, as well as installation of its support structure.
◆ The concave surface makes FRP grating has anti-slip function, while gritted surface will has better anti-slip effect.
