Air Pollution Equipment

We offer a range of biological treatment systems (swift bio-tec), which are compact, skid mounted and ready to use biological treatment systems. Use of moving bed bio reactor technology in the system, reduced the process time and make them extremely compact as compared to the traditional biological systems.

Our systems are delivered pre-piped, pre fabricated and skid mounted. The overall dimensions are selected in manner, which allows the systems to be easily transported through road or by sea. To provide easy access, all the essential equipment such as pumps, blowers, meters, control systems are mounted on the front side of the system. Further, we can also provide machinery compartment with lockable doors, and the systems can be transported easily from one to another.

Operating Principle

Swift bio system works on bio film principle. To provide a large area for the growth of bio film, a specially designed element is used. To form the Bio-media, a large number of small elements are placed in the suspension of the bio-reactor. To circulate the media in the bio reactor, the air is blown under pressure. This process moves the bio-media in the circular motion additionally the air current provides the necessary oxygen to the bio mass.

Gradually a bio films gets formed on the bio media. In conventional static media bio-reactors, the media, which does not get adequate air supply, turns into Black patches. This happens, when the air is blown, it finds the easiest path, thereby bypassing certain bio-media. Under swift systems, since the media in continuously moving, the black patches are avoided. Further, the biological treatment is followed by speeding up the settling system, thereby making the sediments settle down and discharging a clear effluent. Commonly all the systems are designed with 3 stage system and 3 compartments.

The system is best used for producing effluent with less than 300 PPM BOD. Stage 2 can be used, in case of BOD upto 80 PPM. The quality of the effluent water are line with the standards of pollution control boards, can be reused for gardening, irrigation other applications. Additionally, to make the water useful for toilets, wash, laundry, a filtration unit can be added after the biological treatment.
 
Applications
 
The Swift bio systems are used for treating the waste water coming from the following:
 
Sewage treatment systems for:

• Hotels & Holiday Resorts
• Hospitals
• High rise buildings
• Condominiums
• Camp sites
• Off shore platforms
  

Industrial effluent treatment plant for the following industries:

• Dairy and milk processing units
• Food and processed food industries
• Fish processing and canning units

These industrial effluent systems have additional equipments for precise flow measurement, pH meters and chemical dosing pumps, which makes them different from domestic ones.

Most of the demanded environmental control systems include transformer oil purification plants that use a combination of high vacuum treatment system and fine filtration. Since, large numbers of transformers that are used in distribution of power make use of insulating oil, as a result the oil gradually looses its insulating properties to entrance of water (from the moist air). Suspended particles and sludge are generated due to constant oxidation of the oil. Hence the oil needs to filtered and treated properly through a system for removing water and other impurities. Our systems uses a combination of high vacuum treatment system and fine filtration, which extracts water in the form of vapours, then it filter the oil. After that the oil passes through a column of activated alumina for correcting its acidity. Since, these systems are to be moved from one transformer to another, they are mounted on a trailer. The system is pre-wire as well as pre-piped and ready to use. To make the system operation, following things are required to be done:

• Inlet and outlet connections by flexible hose.
• Connecting three phase electrical supply.

Operating Principle:

To remove moisture, dissolved gases and carbon particles which are harmful to preserve isolating properties of transformer oil, our system is used. Further, it is also capable of removing sludge and other types of suspended solids. System is designed to operate on a low temperature and high vacuum principle. When high degree of vacuum is applied, the boiling point of water and vapor pressure of volatile substances drops down drastically. Since, the water vapors from free water and vapors of volatile substances escape from the oil; as a result the isolating properties are improved. High vacuum systems can bring down the level of moisture as low as 5 PPM and dissolved gas content can be brought down to 0.1% to 0.2% by volume.

Main Components:

System comprises of following main components:

• Inlet pump: sucks oil either from transformer or from transformer oil storage tank and is a positive displacement pump.
• Heat exchanger: the oil sucked by the inlet pump is delivered into heat exchanger, which is equipped with electrical heater, capable of heating oil from 600 c to 700 c.
• Filter press: it is coarse filter or pre-filter for edge filter or membrane filter. Certain parts of sludge, free water and some parts of carbon are removed in this filter press.
• Ionic reaction column: when the oil is acidic it is passed through ionic reaction column where acidity of oil is reduced by exchange of ions.
• Edge filter/fine filter: oil is then moved into edge filter column for fine filtration, where suspended solids are removed effectively.
• Dehydrator/degassing column: dehydrator is an efficient means of reducing dissolved gas and moisture content from the oil. Further, it also removes volatile acids which may be present in the oil. Number of stages for degassing and type of vacuum pumping system depends on the moisture content
• Oil discharge pump: it is specially designed pump which is used to pump out the oil collected in the dehydrator/degassing column. 

We offer a wide assortment of air pollution equipment, which are available in either mobile on wheel or fixed to the wall. In maxi mobile, the hazardous welding fumes are extracted using one or two suction arms and cleaned at the electrostatic precipitators. Robustly constructed, our air pollution prevention equipment are designed to occupy minimal space.

Our wide gap heavy duty cells can accept large loads of dirt, thereby widening service intervals. Further, our ranges of air pollution preventive equipment are also supplied with Suyash Bristol electronic filter function control. In addition to that our suction arms have alternatively inside or outside joints and on request we also incorporate a light bulb.

Our range of environment control systems also includes air pollution prevention equipment, which are integrated with ventilator portion, capable of handling air volumes between 2400 and 18000 m3/h along with horizontal or vertical airflow. We offer external available ventilator pressure in customized options as per the client requirements. Further, we also offer a choice between 6mm standard collection cells and 8mm heavy duty cells. Our precision engineered model comes along with airflow choices between horizontal or vertical to cover a large variety of cases with values in respect of versatility filter area compact design and high air volume/pressure capabilities.

Our ionization cell and collection cell is a 2 stage electronic precipitators, works on the principle of charging the contaminants electrostatically and collecting them on a ground plate. In the first stage, the contaminated air is screened by a mechanical prefilter, to remove large particles. After that the air is passed thrugh ionization cell, which charges the particles in the air stream. These charged particles then enter the collection cell, where they are collected on a ground plate. There are two versions of collection cell:

• 6 mm gap (for oilfog with good drainage effect)
• 8 mm "Heavy Duty" cell to allow large absorption space and long maintenance cycles.

 Our 6 mm gap "Standard" Collection cell module provides 20.0 m2 filter surface and the 8 mm gap "Heavy duty" collection cell module gives 14.25 m2 filter surface.
