Multi-Media Filter for Wastewater Reuse

Generally speaking, if your filter is a quartz sand filter, it usually has two main functions:

1. To reduce suspended solids (turbidity). Otherwise, as the system is running, suspended solids increases, which will exacerbate the deposition and other problems.
2. Degreasing. Especially the oily turbid circulation, such as steel rolling and continuous casting, has high oil content and is easy for breeding microorganism and blocking the nozzles.

Activated carbon

Activated carbon is commonly used to adsorb natural organic compounds, taste and odor compounds, and synthetic organic chemicals in drinking water treatment.Adsorption is both the physical and chemical process of accumulating a substance at the interface between liquid and solids phases.Activated carbon is an effective adsorbent because it is a highly porous material and provides a large surface area to which contaminants may adsorb.The two main types of activated carbon used in water treatment applications are granular activated carbon (GAC) and powdered activated carbon (PAC).
GAC is made from organic materials with high carbon contents such as wood, lignite and coal.The primary characteristic that differentiates GAC to PAC is its particle size.GAC typically has a diameter ranging between 1.2 to 1.6 mm and an apparent density ranging between 25 and 31 lb/ft3), depending on the material used and manufacturing process.The bed density is about 10 percent less than the apparent density and is used to determine the amount of GAC required to fill a given size filter.The uniformity coefficient of GAC is quite large, typically about 1.9, to promote stratification after backwashing and minimize desorption and premature breakthrough that can result from mixing activated carbon particles with adsorbed compounds with activated carbon particles with smaller amounts of adsorbed compounds.Iodine and molasses numbers are typically used to characterize GAC.These numbers describe the quantity of small and large pore volumes in a sample of GAC.A minimum iodine number of 500 is specified for activated carbon by AWWA standards.



ACTIVATED CARBON FILTERS:Function

Activated carbon filters provide one of the most effective methods for removing odours and gaseous contaminants.Among their most common uses are in museums and galleries to remove sulphur dioxide, nitrogen dioxide and nitric oxide that cause serious damage to exhibits;Kitchen extract systems to remove odours;The printing industry for the removal of ozone;And many industrial processes for both odour and gas removal.




ACTIVATED CARBON FILTERS:Selection & Operation

Activated carbon comes in two forms:Base carbon and impregnated carbons.While base carbons are suitable for most applications, impregnation will enhance its ability with respect to certain types of gaseous contaminant.Selection therefore requires notification of the types of contaminant to be removed, along with details on air flow and filter measurements to determine the most appropriate format.


The characteristics of the filtration system

1.Manual or automatic control is available;
2.Water distributor is simple, uniform and reliable;
3.Finished water collector has high strength and long service life;
4.Easy to install.Only connect the inlet and outlet to the waste pipe when installing;
5.Less water consumption in backwash:A homogeneous filter is used, so that backwash cycle is extended and the total backwash water volume is greatly reduced;
6.High backwash efficiency:An advanced water collector is used, ensuring efficient backwash effect.
