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.

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.

We deal in a wide range of oil water separators for ships, also known as supersep oily water separator, which make use of latest coalescence principle. These are two stage separators, which includes primary and secondary stages. Under the primary separating stage, the conical or parallel plates are used for removing coarse oil globules.

In the secondary stage coalescing cartridges are used for removing very fine oil globules. Before starting the operation, the entire system is primed with clean water. The pump sucks the oily water from the oily water storage tanks and transfers it to the primary stage. Under this stage a large surface area is provided for the oily water to flow, which helps in coalescing finer oil globules. After that the water with traces of oils is discharged into the secondary stage, where it is passed through coalescing filters.

These filters hold the phase of dispersed oil and when it becomes saturated with oil, large oil globules are released, which gets separated easily. The separated oil is sensed by the level control probes, which are fitted on the top portion of both the columns. These probes activated the corresponding electropneumatic and electromagnetic valves, which drains out the accumulated oil, from the separator. Oil water mixtures containing upto 30% oil can be handled using this system. These systems can operate automatically.

Add On Units:

We are a top-notch manufacturer of oil skimmers, which are available in the following types:

Weir Type Oil Skimmer:

Our weir type oil skimmers are floating oil skimmers, which uses adjustable skimming weir for removing oil floating on water. These skimmers are ideally used for removing large volumes of oil, especially when the thickness of oil film floating on water is high. Fitted with non clogging hydraulic driven pumps, mounted below the skimming weir, our hydraulic power packs are used for driving pump. Further, lowering or raising, the skimming weir is offered with the skimmers. The hydraulic power packs run on either electrical motor or Diesel engine.
Capacities available: 5 m3 / hr to 100 m3 /hr.

Rotating Disc  Skimmer:

Our rotating skimmers are used for removing thin layers of oil floating on water. Equipped with multiple banks of thin stainless steel disc mounted on the common shaft, which rotates at slow RPM, our disc bank assembly are placed insides the floating fiber glass structure. During the rotation, the discs pick up the floating oil, scraped from the discs by the scrappers. The recovered oil gets collected in the oil sump located in the centre of skimmer head, from where it pumped out.

Capacities available: 5 m3/hr to 25 m3 /hr.

Rotating Drum Type Skimmer:

Similar to the disk skimmers, these rotating drum type skimmers, uses a single large drum instead of a bank of small discs. Ideally used for fixed types of applications such as oil water receiving or storing tanks, our drum type skimmers are widely appreciated for its stable performance.

Rope Type Skimmers (Oil Mops):

Our rope type skimmers uses a long loop of specially fabricated polypropylene rope for removing the floating oil. The rope is moved continuously in a loop manner over the oily water. When the oil sticks to the rope, it is passed between the roller, which squeezes out the excess oil sticking to it. The rollers are operated either by an electrical motor or by a diesel engine.

Measurement Principles

The measurement is based upon the principal that when two immiscible liquids are mixed together one in a large quantity and the other comparatively in minute amount, (as water and oil in the case of processed oily water) and if this mixture is exposed to a beam of high intensity energy, then the secondary phase (oil in this case) will scatter part of the incident energy. The intensity of this scattered energy is proportional to the number of secondary phase particles. Over a limited range, graph of concentration v/s scattered energy can be considered to be a straight line.

In 'Purimeter' a sample from oily water separator discharge is continuously exposed to a beam of energy. The intensity of transmitted and scattered energy is measured. In order to eliminate effects of any minute variation in the intensity of transmitted energy, a ratio technique is adopted and the resultant output is amplified, processed, converted and displayed in terms of PPM (parts per million) of oil.

We offer a wide assortment of technically advance electrostatic precipitators, which not only protects the health of the employee but also reduces housekeeping and maintenance cost. These precipitators clean the air of all airborne particulate contaminant, particularly wet or dry in nature and ranges from 0.1 mciron to 100 micron in size. The most harmful particles ranging from 0.1 micron to 10 microns are also covered in this. These microns are harmful for human lungs. This capability of electrostatic precipitators, make them advantageous against filters, bag houses or others. Further, their capability of offering little internal resistance, make them economical from the ventilators pressure rating point of view. In addition to that the agglomeration of free flowing coolant liquids reclaims annually a considerable amount of cutting oil, coolants, lubricants etc.
