Industrial Sand Filter

Industrial sand filters are normally used for removing suspended solids from the aquatic using a single-size filtration media. Industrial sand filters can have graded support media layers or be directly installed finished or on a distribution plate. Manufacturing sand filters are typically used for eliminating suspended solids from the water using a single-size filtration media. The filtration procedure can be decided by regulating the size of the filter sand. The ideal size of each granule frequently varies from 0.35mm to 1.2mm

What Is An Industrial Sand Filter?

As the name suggests, sand filters are filled with sand, generally used for diverse industries. The sand of dissimilar particles is stored in a sand filter, and the bottom of the sand filter contains porous double bottom collector. The sand is often create in a mild-steel, plastic, or concrete housing.

What Is An Industrial Sand Filter?

Industrial sand filters can filter particles down to 10 to 25 microns and achieve at least 5-micron filtration depending upon filter vessel sizing and arrangement. When water flows down the bed, it experienced dissimilar layers of filtration media. It is known as multi-media sand filters. Eventually, smaller particles are removed by each layer which delivers accurate depth filtration and typically increases the filter capability.

The various biological and physical procedures can also be used in a sand filter that can remove more mechanisms. The particles will be collected in the upper coating of the sand filter. To prevent a clogged filter, the water filtration specialists will backwash the filter in which extracted atoms are flushed out so that the filters can be reused again.

Sizing of Industrial Sand Filter:

Some tradition manufacturing sand filter experts can support your project from start to end. Diverse manufacturing sand filters are used based on the properties of the process that needs water treatment. Next are the features that can help in determining the size of industrial sand filters:

• Concentration of solids
• Minor sand filter loading rates and great diameter vessels are needed with higher suspended solid concentrations.
• Discharge limit and destination
• The effluent concentration required in the method stream can help in determining the filter vessel’s size. The vessel diameter can increase as the limits get tighter for discharge allowances.
• Source of backwash water
• Filter backwashing is usually utilized to flush out the suspended solids that were removed in the media bed. The cycle can be self-source or outside-source. On the one hand, self-sourced backwashing uses water that is filtered by the duty filters, while outside-source uses an outside source of water like a storage tank.
• Size of atoms that needs to be filtered
• The loading rate wanted to filter solid atoms from the process has to be lower for small-sized solids.

Advantages of Industrial Sand filters:

• Below are some of the key compensations industrial sand filters offers:
• Removal of various floating particles
• Effective result in the decrease of bacteria and protozoa
• Low maintenance and easy to operate
• Longer life span and effective elimination of particles

Disadvantages of Industrial Sand filters:

• Industrial sand filters offer numerous advantages; however, it has a few cons which one should consider:
• Conveyance can be difficult for heavy filters
• Lesser fine dust can be tough to remove

We are manufacturing supreme quality Waste Treatment Equipment that are integral part of any water treatment plant. These are manufactured from high grade material and are tested on several international parameters before being offered to our clients. Our manufacturing team while keeping in close touch with R&D team designs these components, making these durable and cost effective. Water treatment systems are installed in various industries, such as pharmaceutical industry, power plants, chemical industry, textile industry, oil & gas sector and many more. Our offered water treatment components include pressure sand filter, dealkalizer units and activated carbon filter.

Pressure filters are typically used with hot process softeners to permit high-temperature operation and to prevent heat loss. The use of pressure filters eliminates the need for repumping of filtered water. Pressure filters are similar to gravity filters in that they include filter media, supporting bed, underdrain system, and control device; however, the filter shell has no wash water troughs.

Pressure filters, designed vertically or horizon-tally, have cylindrical steel shells and dished heads. Vertical pressure filters (see Figure 6-2) range in diameter from 1 to 10 ft with capacities as great as 300 gpm at filtration rates of 3 gpm/ft². Horizontal pressure filters, usually 8 ft in diameter, are 10-25 ft long with capacities from 200 to 600 gpm. These filters are separated into compartments to allow individual backwashing. Backwash water may be returned to the clarifier or softener for recovery.

Pressure filters are usually operated at a service flow rate of 3 gpm/ft². Dual or multimedia filters are designed for 6-8 gpm/ft². At ambient temperature, the recommended filter backwash rate is 6-8 gpm/ft² for anthracite and 13-15 gpm/ft² for sand. Anthracite filters associated with hot process softeners require a backwash rate of 12-15 gpm/ft² because the water is less dense at elevated operating temperatures. Cold water should not be used to backwash a hot process filter. This would cause expansion and contraction of the system metallurgy, which would lead to metal fatigue. Also, the oxygen-laden cold water would accelerate corrosion.

UPFLOW FILTERS

Upflow units contain a single filter medium–usually graded sand. The finest sand is at the top of the bed with the coarsest sand below. Gravel is retained by grids in a fixed position at the bottom of the unit. The function of the gravel is to ensure proper water distribution during the service cycle. Another grid above the graded sand prevents fluidization of the media. Air injection during cleaning (not considered backwash because the direction of flow is the same as when in-service) assists in the removal of solids and the reclassification of the filter media. During operation, the larger, coarse solids are removed at the bottom of the bed, while smaller solids particles are allowed to penetrate further into the media.

These filters are the most popular method for removal of turbidity from water. The Pressure Sand Filter consists of a multiple layer of sand with a variety in size and specific gravity. These Filters are designed to remove turbidity and suspended particles present in the feed water with minimum pressure drop. These Filters are custom designed to suit the process requirement. These filters are offered in Mild Steel, FRP or SS construction with face piping and associated Valves.
ConstructionThe Pressure sand filter consists of a pressure vessel either vertical or horizontal, with a set of frontal pipe work and valves, graded silica quartz sand supported by layers of graded under bed consisting of pebbles and gravels, a top distributor to distribute the incoming water uniformly throughout the cross section of the filter, and an under drain system to uniformly collect the filtered water.
ProcessRaw water flows down wards through the filter bed and as the suspended matter, which is treated by addition of a coagulant like alum or poly electrolyte, is retained on the sand surface and between the sand grains immediately below the surface. There is steady rise in the loss of head over a period of time and the flow reduces once the pressure drop across the filter is excessive.

The filter is then taken out of service and cleaning of the filter media is effected by flow reversal also called as backwash. To assist in cleaning the bed, the backwash operation is sometimes preceded by air scouring by way of agitation through the under drain system. The air scouring agitates the sand with a scrubbing action, which loosens the intercepted particles. The filter is now ready to be put back into service.

Water treatment plants are essential because the several types of impurities present in water are extremely harmful to the health of human and animals. Also, they cause damage to the environment as well. Organic matter, turbidity, and several other types of impurities can be removed by dual media filters. They may or may not remove the dissolved solids completely, but there is a sure reduction in the concentration of solids because water softens after filtration.
Media filtration is a simple mechanical process which uses physical and chemical absorption phenomenon. Straining, sedimentation, interception, and diffusion are other important stages. Inertial compaction completes the filtration, and you get clean, soft, sparkling water. Quartz sand, anthracite, coal, silica sand, and garnet are the popular substances used as dual filter media. These filters are equally useful in domestic and industrial applications.

Surface water or wastewater can be filtered using media-based filtration systems. Cleantech offers a wide array of choices designed to meet the diversified requirements of clients. We offer manual, semi-automatic, automatic, and remotely operated models with singular or multiport valves.

Types of Dual Media Filters

There are several types of dual media filters available in the market. The popular choices are:

✦ Anthracite Filters

It is used in dual-media filtration with sand because its specific gravity is lighter than sand. Due to high carbon content, it resists the majority of chemicals. It is a high physical strength material which is used in a wide variety of applications. It has high removal capacity of SS and turbidity. It is used as the carrier for bio film treatment. Micro-flocks grow easily in the medium.

✦ Calcite Filters

Other than filtration, Calcite Filters achieve a high degree of neutralization. They raise the pH value of water so that it achieves non-corrosive equilibrium. Increased water quality avoids leaching of copper pipes, metal pipes, and plumbing components. Since Calcite is naturally found component, it is a cost-effective solution. The cartridge designs fit a majority of filtration plants.

✦ Activated Charcoal Filters

They are ideal for removing residual disinfectants as well as organic constituents in the water so that the health hazards can be minimized. The filters also greatly improve the taste of water. When treated water is supplied to other filtration systems such as RO, it saves from organic fouling or oxidation. Higher molecular weight of particles means the higher efficiency of carbon filters. Similarly, lower pH value means the removal is efficient. Activated carbon effectively removes high contaminant concentration. It is available in large, medium and fine mesh sizes.

Typical Construction of Media Filtration Plant

Multimedia filtration uses three or more media layers whereas sand filters use a single layer of a particular grade. In the single media filters, the smallest (or finest) media particles are on the upper layers of media bed and bigger and heavier particles are on the lower layers. Since all filterable particles are within 2 to 3 inches on the upper layers, this filter doesn’t use the media depth optimally.

As a result, the filter run times shortens, and there are filter blinds in the process. Three types of media layers are used in these filters; Garnet, anthracite, and sand. Since there is a big disparity in their densities, they make the filtration system effective.

As far as filtration media per unit volume is concerned, Anthracite has the largest PUV value followed by sand and garnet. Due to the differential PUV value, large contaminations get trapped in the first layer, and small contaminations particles shift down to the lower layers. Therefore, efficient turbidity removals and extended run times between two backwash cycles can be achieved.

They are ideal for removing residual disinfectants as well as organic constituents in the water so that the health hazards can be minimized. The filters also greatly improve the taste of water. When treated water is supplied to other filtration systems such as RO, it saves from organic fouling or oxidation. Higher molecular weight of particles means the higher efficiency of carbon filters. Similarly, lower pH value means the removal is efficient. Activated carbon effectively removes high contaminant concentration. It is available in large, medium and fine mesh sizes.

Typical Construction of Media Filtration Plant

Multimedia filtration uses three or more media layers whereas sand filters use a single layer of a particular grade. In the single media filters, the smallest (or finest) media particles are on the upper layers of media bed and bigger and heavier particles are on the lower layers. Since all filterable particles are within 2 to 3 inches on the upper layers, this filter doesn’t use the media depth optimally.

As a result, the filter run times shortens, and there are filter blinds in the process. Three types of media layers are used in these filters; Garnet, anthracite, and sand. Since there is a big disparity in their densities, they make the filtration system effective.

As far as filtration media per unit volume is concerned, Anthracite has the largest PUV value followed by sand and garnet. Due to the differential PUV value, large contaminations get trapped in the first layer, and small contaminations particles shift down to the lower layers. Therefore, efficient turbidity removals and extended run times between two backwash cycles can be achieved.

 

Water treatment plants are essential because the several types of impurities present in water are extremely harmful to the health of human and animals. Also, they cause damage to the environment as well. Organic matter, turbidity, and several other types of impurities can be removed by dual media filters. They may or may not remove the dissolved solids completely, but there is a sure reduction in the concentration of solids because water softens after filtration.
Media filtration is a simple mechanical process which uses physical and chemical absorption phenomenon. Straining, sedimentation, interception, and diffusion are other important stages. Inertial compaction completes the filtration, and you get clean, soft, sparkling water. Quartz sand, anthracite, coal, silica sand, and garnet are the popular substances used as dual filter media. These filters are equally useful in domestic and industrial applications.

Surface water or wastewater can be filtered using media-based filtration systems. Cleantech offers a wide array of choices designed to meet the diversified requirements of clients. We offer manual, semi-automatic, automatic, and remotely operated models with singular or multiport valves.

Types of Dual Media Filters

There are several types of dual media filters available in the market. The popular choices are:

✦ Anthracite Filters

It is used in dual-media filtration with sand because its specific gravity is lighter than sand. Due to high carbon content, it resists the majority of chemicals. It is a high physical strength material which is used in a wide variety of applications. It has high removal capacity of SS and turbidity. It is used as the carrier for bio film treatment. Micro-flocks grow easily in the medium.

✦ Calcite Filters

Other than filtration, Calcite Filters achieve a high degree of neutralization. They raise the pH value of water so that it achieves non-corrosive equilibrium. Increased water quality avoids leaching of copper pipes, metal pipes, and plumbing components. Since Calcite is naturally found component, it is a cost-effective solution. The cartridge designs fit a majority of filtration plants.

These filters are the most popular method for removal of turbidity from water. The Pressure Sand Filter consists of a multiple layer of sand with a variety in size and specific gravity. These Filters are designed to remove turbidity and suspended particles present in the feed water with minimum pressure drop. These Filters are custom designed to suit the process requirement. These filters are offered in Mild Steel, FRP or SS construction with face piping and associated Valves.ConstructionThe Pressure sand filter consists of a pressure vessel either vertical or horizontal, with a set of frontal pipe work and valves, graded silica quartz sand supported by layers of graded under bed consisting of pebbles and gravels, a top distributor to distribute the incoming water uniformly throughout the cross section of the filter, and an under drain system to uniformly collect the filtered water.ProcessRaw water flows down wards through the filter bed and as the suspended matter, which is treated by addition of a coagulant like alum or poly electrolyte, is retained on the sand surface and between the sand grains immediately below the surface. There is steady rise in the loss of head over a period of time and the flow reduces once the pressure drop across the filter is excessive.The filter is then taken out of service and cleaning of the filter media is effected by flow reversal also called as backwash. To assist in cleaning the bed, the backwash operation is sometimes preceded by air scouring by way of agitation through the under drain system. The air scouring agitates the sand with a scrubbing action, which loosens the intercepted particles. The filter is now ready to be put back into service.We Offer the following Range of Pressure Sand Filters:FRP Pressure Sand Filters up to 2000 mm DiameterVertical MS Pressure Sand Filters up to 5000 mm DiameterHorizontal MS Pressure Sand Filters up to 4000 mm DiameterPressure Sand Filter - Salient Features:Efficient Turbidity RemovalMOC - FRP, MSRL, MSEP & SSStandard and effective multi grade sand media.Low Pressure drop across the vesselOptional Air scouring available.Manual, Semi Automatic & Automatic Options
