Water filtration gravel / pebblestone is a coarse granular material that is commonly used as a filtration medium in water treatment systems. It typically consists of small, round, or semi-angular stones that range in size from 2 mm to 40 mm.
Our water filtration gravel is washed and screened into different mesh sizes based on the requirement and application. Our filter gravel is mined from ancient riverbeds in Jharkhand and West Bengal. It is naturally hard, and predominantly quartz aggregate making it perfect for water purification applications.
We are among the leading filtration gravel manufacturers & suppliers in India for water treatment applications. We are both gravel producers as well as traders, and have been supplying gravel for industrial and city water treatment projects as well as pea gravel that is used mostly on bore wells / tube wells.
We supply material by truckloads in tons of gravel or packed in 40Kg HDPE bags. Our cost of gravel in bulk quantity most competitive.
Our filtration gravel is suitable for the below purposes:
Gravel is often used in combination with other filtration media, such as Water Filtration Sand, anthracite, iron removal media and activated carbon, to remove impurities and contaminants from water. The coarse nature of gravel makes it an effective filter for removing large particles, sediments, and debris from the water. The spaces between the stones also provide a large surface area for the growth of beneficial bacteria that help break down organic matter and other pollutants.
Frequently Asked Questions
Q: What is Water Filtration Gravel / pebblestone and how is it used in water treatment?
A: Gravel Filtration Media is a natural filter media and a type of coarse aggregate that is commonly used as a filtration media in water treatment. It is used as a support layer for other filtration media, such as sand, to improve the overall performance of the filtration system. Gravel is also used as a bed for the distribution of water in rapid gravity filters.
Q: What are the benefits of using Filtration Gravel Media / pebblestone in water treatment?
A: The use of gravel filter media / pebblestone in water treatment offers several benefits, including:
- Enhanced filtration performance: Water Filtration Gravel / pebblestone provides a larger surface area for the attachment of microorganisms, which improves the effectiveness of the filtration process and is also used as sedimentation removal media.
- Improved flow rate: Gravel Filtration Media / pebblestone helps to distribute water evenly across the water filtration media, allowing for faster and more efficient filtration.
- Longer filter life: The use of Water Filtration Gravel as a support layer for other filtration media can help to prevent clogging and extend the life of the Water Filtration Unit.
Q: What types of gravel are used in water treatment?
A: The most commonly used types of Filtration Gravel in water treatment are, gravel with high silica content which are mainly found in gravel pits and gravel quarries in some parts of West Bengal and Jharkhand. These types of gravel are selected for their size, shape, hardness, silica content and density which are important factors in determining their effectiveness in water treatment.
The above mentioned gravel pits and quarries are also approved in accordance with IS 8419 which is the code under which the gravel is approved by the government for use in water treatment.
These gravel pits and gravel quarries are mainly owned and excavated by a company named Pebblestone Drive with its headquarters at Kolkata, West Bengal which is one of the largest Filtration Gravel manufacturer and supplier throughout India.
Q: How is water filtration gravel / pebblestone installed in a water treatment system?
A: Gravel Filter media / pebblestone is typically installed as a layer at the bottom of a filtration vessel or tank, with other filtration media layered on top. The thickness of the gravel layer depends on the size and type of filtration media being used, and the specific requirements of the water treatment system.
Q: What are some common applications of water filter gravel / pebblestone in water treatment?
A: Gravel Filter Media / pebblestone is commonly used in various water treatment applications, including:
- Municipal water treatment: Gravel is used in rapid gravity filters to remove suspended solids and other impurities from drinking water.
- Industrial water treatment: Gravel also known as Industrial Gravel Media is used in industrial water treatment systems to remove contaminants from process water and wastewater.
- Residential water treatment systems: Water Filtration Gravel / pebblestone can be used in home water filtration systems to remove sediment and improve water quality.
• Swimming pool filtration: Gravel/pebblestone is used in swimming pool filtration systems to remove debris and other impurities from pool water.
- Effluent Water Treatment: Water Filtration Gravel /pebblestone are a common component in the effluent treatment process and is used as a filtration media for removing impurities and contaminants from wastewater. Gravel beds are commonly used as a support layer for other filtration media, such as sand or activated carbon, which improves the overall performance of the filtration system.
Q: What are the types of Filteration Process where gravel is used?
- Rapid Gravity Filters (RGFs): Gravel filtration media / pebblestone beds are used in RGFs to remove impurities and contaminants from wastewater as it passes through the bed of media. The gravel provides a large surface area for the attachment of microorganisms, which can help to break down and remove contaminants.
- Trickling Filters: Gravel Filtration Media / pebblestone beds are also used in trickling filters to treat wastewater. In this process, wastewater is sprayed onto the gravel bed, where microorganisms living on the media help to break down and remove contaminants.
- Aerobic Digestion: In some wastewater treatment processes, water filtration gravel / pebblestone are used in aerobic digestion tanks, which provide an environment for the breakdown of organic matter in wastewater by microorganisms.
- Anaerobic Digestion: Gravel filter media / pebblestone can also be used in anaerobic digestion tanks, which are used to break down organic matter in wastewater in the absence of oxygen. In this process, gravel provides a medium for the growth of microorganisms that can convert organic matter into biogas.
