They are commonly used as a pretreatment step before processes such as activated carbon filtration, ultrafiltration and reverse osmosis.
Pressure Sand Filter Applications
- Industrial water treatment
- Effluent treatment plants
- Sewage treatment plants
- RO pretreatment
- Process water treatment
- Cooling-water systems
- Utility water treatment
Pressure Sand Filter Features

Activated Carbon Filters
Ravi Enviro manufactures and supplies activated carbon filters for industrial water and wastewater treatment applications. Activated carbon filtration uses adsorption to reduce specific organic compounds, colour and odour and can be used as a polishing stage depending on feed-water characteristics and treatment requirements. Activated carbon filtration is not designed to remove every type of contaminant, such as dissolved salts, nitrates, fluorides or microorganisms, and the appropriate treatment technology should be selected according to the water-quality requirements.
Activated Carbon Filter Applications
- Water treatment plants
- Effluent treatment plants
- Sewage treatment plants
- RO pretreatment
- Process water treatment
- Pharmaceutical industries
- Food and beverage industries
- Industrial wastewater treatment
Activated Carbon Filter Features
- High-quality activated carbon media
- Customized filtration capacity
- Industrial-grade filter construction
- Suitable for water and wastewater applications
- Easy media replacement and maintenance
- Designed according to application requirements
Side-Stream Filters
Side-stream filters are used to remove contaminants, debris, and suspended solids from water. This filter can help industries prevent fouling, scaling, and corrosion, leading to better functionality of the plant. Our side-stream filters are designed to work efficiently and minimize the need for manual cleaning, thus saving labour costs. They are compact and very easy to install into your existing plant.
Walnut Shell Filters
These filters are used to remove oil and suspended solids with accuracy. Walnut shell filters are used to remove oil and suspended solids from suitable industrial wastewater streams. The filtration performance depends on feed-water characteristics, contaminant loading, operating conditions and system design. What’s unique about these filters is that they have a very strong backwashing system, which gets activated when the bed is full of contaminants, resulting in a self-cleaning system. These filters are a very good choice for industries as they are easy to maintain and don’t require any surfactants or chemicals.
Membrane Filters
A membrane filter is a type of industrial filter that purifies pollutants based on their size. It uses a porous membrane and only permits specific particulate dimensions to pass through the membrane while retaining others. Our membrane filters are used in pharmaceutical industries, water purification plants, food and beverage, and industrial setups. Based on sizes, REIPL offers membrane filters such as ultrafiltration, microfiltration, and reverse osmosis filters. Filters manufactured at Ravi Enviro Industries Private Limited are highly efficient, cost-effective, and versatile.

Applications of REIPL Filters
- Effluent Treatment Plant
Filtration systems are used as part of ETP treatment trains to reduce suspended solids, oil, organic contaminants and other targeted pollutants depending on the wastewater characteristics and treatment objectives. Pressure sand filters can be used for suspended-solids and turbidity reduction, while activated carbon filters may be used for polishing applications where reduction of specific organic compounds, colour or odour is required. Walnut shell filtration can be used for suitable oily wastewater streams, while membrane systems may be incorporated where additional separation or water-reuse requirements exist. The appropriate treatment sequence depends on the characteristics of the effluent and the required treated-water quality.
- Sewage Treatment Plant
In sewage treatment plants, filtration systems can be used as part of tertiary treatment to reduce remaining suspended solids and improve treated-water quality. Activated carbon filtration may be used for specific polishing requirements such as reduction of colour and odour, while membrane filtration can provide additional separation where higher-quality treated water or reuse is required. The appropriate treatment process depends on influent characteristics and the intended reuse application.
- Cooling Towers and HVAC Systems
Side-stream filters are essential for cooling tower systems to continuously remove solids and maintain efficiency. REIPL’s side-stream filters treat a portion of water, capture pollutants, and bio-growth. This way, it improves the life of heat exchangers and chillers.
- Refineries and Petrochemical Industry
In the oil and gas industries, the wastewater contains a lot of free and emulsified oil, hydrocarbons, and fine solids. Walnut shell filters are very useful in such conditions, as they are oil-repellent in nature with long-lasting media. These filters are used for polishing wastewater before biological treatment or reuse.
- Pharmaceutical, Food, and Beverage Industry
These industries require a stringent level of water purification. Here, the activated carbon filters and membrane filters serve their purposes effectively. REIPL is an expert in serving these industries, and our filters are compliant with hygiene as well as performance standards, making them perfect for utility water filtration.
