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.  

We are offering MBBR Media to our clients. They are made of the polymeric materials with the promoted additions of bio-enzyme. It improves the enzymatic catalysis. It is an advanced kind of suspension carriers. They are very easy to clean and require low maintenance. We serve them in lots of models and designs. It has a thermo form biofilm reactor and has strong ability to contaminant. MBBR technology provides cost-effective treatment with minimal maintenance since MBBR processes self-maintain an optimum level of productive biofilm. Additionally, the biofilm attached to the mobile biocarriers within the system automatically responds to load fluctuations.

 ® “EPNOL” Standard Low Plasticizer EPDM Membrane   EPDM is a synthetic rubber which is custom moulded /specially blended for this application. The compound formulation and moulding/extruding technique are critical to ensure that the membraneDDS

The Dual Media Filter utilizes combination of Filter Media and Anthracite for higher flow rates with a smaller footprint. High filtration velocities are achieved by proper selection of Media, and designing of Distribution and collection systems. These filters are offered in Mild Steel, FRP or SS construction with face piping and associated Valves.  

Refrigeration dryers A microprocessor based control device is an advanced solution for drying compressed air. Compressed air is fed into the dryer and precooled in the air-to-air heat exchanger by the cold compressed air. The pre-cooled air passes through the refrigerant-to-air heat exchanger where it is further cooled to the required pressure dew point. The moisture in the compressed air condenses and is collected and discharged automatically. Finally, the cold discharged air is re-warmed by the incoming compressed air. This saves energy and prevents any moisture from forming downstream of the dryer in the compressed air system. Advantages at a glance : Multi-functional display Load controlled energy consumption; reduction down to 10% of nominal energy consumption Load controlled drain Low voltage monitoring Optional dry contact for alarm signal and analog signal 0-10 V for dew point temperature Maximum operation parameters: inlet temperature 60° C, ambient temperature 50° C for the whole series One component refrigerant R 134a, ozone factor zero Compact and easy to install cabinets   Adsorption Dryers Purifying compressed air on demand, free of particles and condensate, helps decrease running costs. Equipment consisting of integrated pre- and after-filters and an electronically level-controlled drain ensure pure, dry and oil-free compressed air with no loss of compressed air from condensate drainage. Economical drying is guaranteed by an integrated microprocessor, which controls the adsorption and regeneration cycles. Heat regenerative driers can be offered with the following options: Explosion proof version Pressure dew points of -70° C Steam regeneration systems and dryers for higher pressures and higher flow rates All functions, sequences, operating states and faults are displayed by LEDs on flow charts and they are monitored continuously Control of the air recovery temperature

The Activated carbon Filters are designed to remove free chlorine, organic matter, odour and Colour present in the raw water and waste water. Due to its high degree of micro porosity, activated carbons provide a huge surface area.Activated carbon filter operates through adsorption. Adsorption is directly related to the surface area of the media. This great surface area furnishes a huge adsorption area for organic as well as chlorine molecules to attach themselves. The Activated Carbon Filters consist of Activated carbon granules supported by very fine quartz filter media. Various grades of carbon are available for specialized treatments. Filtration is the most frequently used, robust method to remove suspended solids from water. The Filter consists of a multiple layer of sand/ Filter Media with a variety in size and specific gravity. The Filters are designed to remove turbidity and suspended particles present in the feed water with minimum pressure drop.
