Iron Removal Filter in Kolkata

Iron Removal Filter:

The Iron Removal filters that we manufacture are widely used to eliminate turbidity, suspended particles, color, odor and iron that are available in raw water. These iron removal filters are known for their easy operation and give crystal clear water. Our iron removal plants are accurately designed to fulfill our client's specific requirements. These filters purify water from sand without clogging the filter where the raw water passes through the layer of processed catalyst & quartz filter media respectively. The dissolved ferrous iron salts are converted into insoluble ferric salt and precipitated over the filter bed and then the iron free filtered water comes out. Only backwashing with clear water is required for cleaning the bed. The entire range can also be customized as specified by the clients.

Water Process Description Raw water is chlorinated or Ozonated to oxidize the organic impurities (kill bacteria and virus). This water is passed through Multi Media Filter with the help of Feed pump of suitable capacity to remove suspended impurities followed by Activated Carbon Filter to remove excess chlorine (de-chlorination), odour, colour and turbidity due to colloidal suspended impurities and organic impurities. De chlorinated water is then dosed with Anti Scalent Solution to avoid scale formation on the membrane or passed through Softener to remove hardness. Softened water is further passed through 10-micron cartridge filter to remove micron particles to avoid clogging of the RO membrane and to improve the silt density index. Water further passed though RO Unit which is complete with High Pressure Pump, Membranes with Pressure tubes, Electrical control panel and wet panel, piping with valves and all the required accessories viz., pressure switch, solenoid valve etc. Reverse Osmosis unit will reduce the dissolved Salts up to 95% of the In feed TDS. Treated water from RO unit will be stored into SS tank. This treated water is then passed through 0.2 micron cartridge filter before it is taken for the filling. Ozonator unit producing ozone gas is installed in series at the outlet of UV System to provide residual effect of ozone to the water.

Pet Strech Blow Moulding Machine:


All the qualities of PET :

The PET bottle is a great success in many countries. And no wonder, producted by the biaxially oriented blow moulding process, PET or Polyethlene Terephthalate– bottles combine outstanding performances and aesthetic qualities. They give you the super crystal clarity needed to show any product to advantage. They have excellent carbonation retention properties and a good barrier to oxygen. Extremely resistant to breakage, light to handle and transport, and safe to health and environment.

To the advantage of PET itself, the extraordinary characteristics of the Canada Pure Fillers PET Bottle Blowing machines are added simplicity, compactness, reliability and flexibility. Quickly installed, the machine is ready for producing bottles of various shapes and contents as the changing of the moulds are rapid. Renowned for these advantages, it is the small “two steps” machine which is the most sold in world and gives satisfaction to hundreds of producers for various different applications like mineral water, carbonated Softdrink project equipment, edible oil, detergents. This is an ideal system for economical production in small series of quality bottles.

Multipurpose Infrared Rotary Heater :

Six to eight vertically horizontally and angularly adjustable double lamps can be turned to allow a more uniform heating of any type of preforms. Before blowing preheating is achieved by recirculation of hot air exhausted by lamps and the system automatically adjusts to changes in the ambient temperature. An oven with ten lamps (optional) permits the heating of thicker preforms. An oven with 24 lamps permits the heating of 2 litre bottle preform. The control cabinet is equipped with a programmable microprocessor with Error Status Indicator. Setting and adjusting of the controls can be performed manually. For special climates the cabinet can be air conditioned.

Easy Access :

The pneumatic, hydraulic and electrical equipments, as well as the cooling system, are easily accessible. Minimum replacement time is required when one type of bottle mould is changed for another one. No special tools are needed.


The bi-axial orientation : PET is certainly the ideal material. But to retain that title, it also needs the full benefits of bi-axial orientation.

Bi-axial orientation requires two-stage production: the perform is first produced and then, within a precise temperature range, it is stretched both axially, (thanks to stretching rods), and radially by blowing. It is this process which gives the container its strength. These two phases can be carried out on one double acting machine (one stage) or separately on two different machines (two stages).

The PET :

The application of this process to PET (Polyethylene terephthalate) product bottles, jars and containers which perform remarkably and uniquely: giving clarity excellent properties of carbonation retention, ingress of oxygen and virtually unbreakable, light to handle and transport and above all, kind to the environment and recyclable. This combination of properties has opened up new and important markets, PET has become the favored material in number of applications, notably for projects and equipment for carbonated and non-carbonated soft drinks, mineral water, vegetable oils and vinegar. But the new generation of applications is covering a still more extensive range of detergents and cleaning products, wines and other alcoholic drinks, fruits juices, certain conserves sauces, ketchup and mustard, cosmetic and pharmaceutical products, industrial paints and oils chemical products etc., A range of new markets with a promising potential.

Water Source :

  • A system of small modular units has many advantages over one large machine.
  • You can begin small with the minimum investment.
  • As Business grows, additional units can be acquired.
  • Production volume can easily and economically be adjusted to market fluctuations.
  • Bottles of different sizes and weights can be produced simultaneously on different units.
  • Change-over from one production to another can be rapidly effected.
  • The PET system is well known for its solidity and reliability according to world standards.
  • A simple system to operate means short training for operators.
  • As the machine requires very little maintenance, cost related to no operating machines are negligible
