Equipment For Wastewater Treatment Plants
We supply a comprehensive range of equipment used in waste treatment plants, the main being surface aerators, fixed aerators and floating aerators. The surface aerator is a vertical shaft aerator that helps in mechanical means of oxygen transfer to industrial and sewage plants. The floating aerators are available in different designs and sizes and are designated as NSA-FL range. This range also includes mixers and agitators are used to mix/agitate chemicals, polymers, coagulants and flocculates with or in water. We also supply screens that help in removing large particles from the wastewater.
We are also manufacturing superior quality of sewage treatement plants, wastewater treatement plants, compact sewage treatement plant, packaged sewage treatement plan, packaged wastewater treatement plants, comapct waste water treatement plants and other water treatement plant. Our machines have proven record of satisfying our worldwide clients and have been highly appreciated in countries like Morroco, Jordan, Africa, Sri Lanka and more.
Clarifier / Mechanical Scraper Systems
A clarifier is a round shaped conical bottom funnel type tank. Waste water
to be treated enters by a pipe into the clarifier located at the centre of
the clarifier and is so designed as to reduce the velocity of the incoming
water and also ensure that incoming water is uniformly distributed in all
directions to fully utilise tank capacity and to have maximum possible
settling time. Adequate time is built into the design to cause separation of
settleable material from water. This matter gradually travels down to the
slope of clarifier and becomes sludge. The water on top surface is without
these particles and is much clearer. This clearer water is designed to over
flow out via launder.
Clariflocculators
Where water has to be clarified through addition of flocculants and where
design considerations demand, clariflocculators provide an optimum solutions
by giving high efficiency and economy of space and operation. In Akar
clariflocculators, effluent mixed with flocculants is guided to the
flocculation chamber. In the flocculation chamber rapid settling flocs are
formed. The clariflocculator is designed as to cater to the capacity
requirement both in terms of quantity of effluent as well as the flocs
settling time consideration.
Oil Skimmers / Oil Removal Systems
Oil skimmers or Oil removal systems are used in a waste water treatment plant to remove
excess oil from sewage or Industrial Effluent water. In a sewage treatment
plant oil gets accumulated after the kitchen. Kitchens use most of the oil
and this oil contaminates sewage. Similarly in the case of industrial
effluent treatment plant oil is released from industrial processes as waste
water used for washing contains oil which must be removed for more efficient
treatment. Oil skimmers are of different types. Tube type oil skimmers, belt
type oil skimmers etc.
Dissolved Air Floatation Systems
Akar Dissolved Air Flotation (DAF) system is the most versatile and
effective wastewater processing equipment to remove emulsified oil which is
other wise extremely difficult to separate from water. As a separation
device it generally will affect the highest solids capture and will yield
the highest level of recovered solids under a wide range of flow conditions.
Oil/grease and suspended solids removal rates of greater than 95% are
normal. There are some sites reporting 99.9% O&G and SS removal. Because
of the outstanding performance and reliability, the DAF is the preferred
process for a wide range of industrial treatment problems. Akar has supplied
many DAF systems to prestigious clients. Some of these systems have been
functioning since the last ten years.
Settling Tanks / Lamella Clarifier
These are also known as clarifiers or sedimentation tanks. They can be
circular or rectangular. Settling tanks operate on the principle of slowing
the flow sufficiently so that slow settling materials can sink and be
collected and removed. Typically, 60 to 70 percent of suspended solids and
30 to 40 percent of organic matter in raw sewage is removed. Floating oil
and fats can be removed if a scum collection system is installed. Settling
tanks are also an important part of other treatment processes, particularly
biological treatment where they are normally called secondary clarifiers.
The sludge which collects at the bottom needs to be removed frequently, and
usually mechanical scrapers are installed to do this. The sludge produced
must be further treated before disposal, usually by aerobic or anaerobic
digestion, chemical stabilisation, composting, or incineration.
