FLOATING AERATOR AND FIXED AERATORS

 

ENFAB has been the pioneers in the design and manufacturing of  Floating Aerators which has found its application in almost all the industrial belt of  South India. Enfab surface aerators are recommended for aeration in activated sludge treatment, aerated equalization, aerated lagoons, aerobic sludge digestion, contact stabilization and

preparation. Enfab aerators have high oxygen transfer efficiency. Enfab equipments are used to perform various unit operations either by settling or floating in on the removal  of surface, such as separation of suspended impurities mixing etc. for the treatment of water sanitary sewage or industrial waste water.

DIFFUSED AERATION SYSTEM

 

Diffused Aeration is process of oxygen by molecular diffusion through the interface film between the air and liquid which increased in proportion to the interfaced area. The efficiency of oxygen transfer depends on many factor including the type, size and shape of the diffuser. The airflow rate the depth of submersion, tank geometry including the header diffuser location and waste water characteristics. Aeration devices are conventionally evaluated in clean water and the results adjusted process opening condition though widely used conversion factor.

DOSING SYSTEM

 

The dosing system is introduced for neutralizing the pH and other parameters effluent before taking for treatment. The construction consists of 2 Nos. of agitator driven by more. One agitator is clockwise and the other in anti clockwise direction. The connection between the motor and agitator will be through pulleys or sprockets. The shaft paddles made out of  SS 304 is connected to the housing by special couplings. The agitators are mounted on a bed frame spanning tanks. Speed of the agitators is 300 RPM.

   
    CLARIFLOCCULATORS

CLARIFLOCCULATORS

 

ENFAB provides a special dual drive mechanism in which the clarifier scraping and Flocculating paddles are separately driven driven in concentric compartment. Flocculation and clarification are combined in a single tank in this equipment. Chemically dosed effluent is uniformly distributed in inner compartment for flocculation clarification place in out of compartment. Clarified effluent is discharged in to the peripheral launder and the sludge is scrapped to a central packed from where it can be easily discharge.

AEROBIC FIXED FILM REACTORS

 

Waste water treatment is carried out in three stages. The primary, secondary and tertiary Stage. The second or biological stage is the most important of them all. It is a simplest Form of treatment. The plug flow increases the efficiency for high treatment. No recycle Of sludge and monitoring of MLSS. Its retention period is 6 to 8 hrs. this system is very Compact.

Aerobic submerged fixed film process consist of three phases, packing, bio film and liquid. The BOD and or NH4-N removed from the liquid flowing past the bio film is oxidized. Oxygen is supplied by diffused aeration in to the packing or by being predissolved in to the influent waste water. Aerobic fixed film process include down flow packed bed reactors. The type and size of packing is a major factor that affects the performance and operating characteristics of submerged attached growth process. Designs differ by their packing configuration and inlet and outlet flow distribution and collection.

CLARIFIER

CLARIFIER
 

Enfab Clarifiers are used extensively in chemical effluent, textile effluent, biological effluent, various type of industrial processing and even metallurgical processing where the efficient separation of solids is the “NEED”. The clarifiers designed and manufactured at Enfab is either bridge spanning the tank or centre column supported and cover wide range of tank sizes and flow requirement. The drive unit can be central or peripheral driven and are also manufactured with half/full scrapping arm. The scrapping arms are with neoprene rubber/PP/HDPE/ brass squeezes to scrap the floor to bring the settled sludge to the central sludge well.

IRON REMOVAL FILTER

 

These are special application filters to reduce iron content in the water. The system comprised Ms structural rubber lined vessels which contain the iron absorbent media and automatic multiport Fleck valves. The operating systems is automatic and no chemicals are required for media regeneration. These standard systems are available in capacities from 500 to 12,000 litres per hour, for larger capacity Enfab will design and fabricate filters, suitable to the requirement of customer.

    ULTRA FILTRATION

ULTRA FILTRATION

 

Particles of about 0.005 microns (mw>1000 daltons) or larger are retained by ultra Filtration membranes. Low  molecular substances ( eg. Sugar and salt) pass through membranes. Enfab with collaboration from UF membrane manufactures / suppliers, is supplying the system to suit the clients requirements.

RO SYSTEM

RO SYSTEM
 

When a pressure greater than the osmotic pressure is applied to the concentrated solution water flows from the concentrated to the dilute solution side. The flow of water through semi permeable membrane from the more concentrated solution to the dilute solution is called Reverse osmosis

Reverse osmosis membranes allow only water to pass through them. Salt and dissolved Organic substances with a high molecular weight weight than 50 Doltons are retained almost Without exception. Enfab had supplied R.O. system  for the capacity upto  75m3/hr.
