We are manufacturing a wide range of filter papers & pads on a very highly sophisticated production plant. The entire process of manufacturing is untouched from the pulping stage to the finished product. This is a high precision completely automatic plant which ensures an uniformly produced filter media for excellent purity and free from external contaminants qualities vital for sensitive industries like drugs, pharmaceuticals, foods, beverages, chemicals, cosmetics etc.

Our raw material is continuously monitored for quality control. Constant laboratory tests are conducted to check filtration efficiency, pad porosity, absorbency, Filteration speed and bursting factor. The fibers of our filter paper & pads are also subjected to a special porous chemically inert wet-strength impregnation process to impart very high mechanical strength while filtering aqueous. We also manufacture handmade filter papers & pads as per customers requirement. We use pure Cellulose Fibre , Cotton linter Pulp in manufacturing Quality filter Papers

Why use Cotton Linter Pulp In Filter Papers !

The main reason behind using Cotton Linter Fibres for making filter Papers is that it requires less beating / refining to achieve desired freeness level which makes it suitable for maintaining a specific porosity required for different grades of filter paper.

The primary characteristics of paper grade cotton pulp are as follows:
-- high physical strength
-- excellent aging and non-yellowing properties
-- good color retention
-- high temperature resistance
-- good light and UV resistance
-- wide range of fiber lengths possible
-- wide range of freeness properties possible
-- high brightness
-- high level of cleanliness and purity

Basic Filtration Concepts

Liquid Flow Rate :
Under practical filtration conditions, the liquid flow rate will depend on a number of factors, many of which will be specific to the solid/liquid system being filtered. In order to compare filter performances, a standardized set of conditions is required which will characterize liquid flow rate for a given filter without the complicating secondary effects derived from the presence of particulates. Liquid flow rate is tested with prefiltered, deaerated water using a flat filter subjected to a constant hydrostatic head. Test methods based on quadrant folded filters are considered unreliable.

Ash Content :
Determined by ignition of the cellulose filter at 900°C in air. Ash content is essential in gravimetric applications and also a useful measure of the level of general purity.

Particle Retention (liquid) :
In a filtration process, the particle retention efficiency of a depth-type filter is expressed in terms of the particle size (in µm) at which a retention level of 98% of the total number of particles initially challenging the filter is obtained. It is customary to quote the retention levels at 98% efficiency to allow for secondary filtration effects.

Filter Papers :
Our qualitative and quantitative filter papers are, with few exceptions, manufactured from high quality cotton linters which have been treated to achieve a minimum alpha cellulose content of 98%. These cellulose filter papers are used for general filtration and exhibit particle retention levels. The different groups of filter paper types offer increasing degrees of purity, hardness and chemical resistance.
