SEWAGE TREATMENT PLANTS -(STP)
The Raw Sewage and Waste Water collected from the Toilets, Laundry, Kitchen, floor Cleaning, etc. can be treated both chemically and biologically to the extent of removing all the impurities. However, most of the Treated Water is currently being recycled for either flushing of Toilets or Gardening/Landscape.
This Waste Water could be anywhere from domestic to industrial and the treatment systems vary based on the raw water or effluent conditions.
The equipment related to STPs of Various Capacities are done with In-House designs and manufacturing built-in capacities.
The equipment like:
- Bar Screen & Chambers for larger Solids removaletc.
- Alum & Polymer Dosing preparation tanks & its dosingsystem.
- Aeration System.
- Particle Suspension Settling System.
- Particle Suspension Trapping System
- Odour Removal system ( Activated carbon Filter)
- Mechanical Ventilation
a. Surface Aeration
b. Diffused Aeration (Coarse & FineBubblers)
c. Submerged Aeration
a. Tube Settlers
b. Plate Settlers
d. Clari- flocculators
a. Slow Sand Filtrations
b. Pressure Sand Filters
- Dosing chemical preparation Reactor Dosing System.
- Disinfection Treatment.
- Hypo Dosing System
- Final Water Treatment Systems
a). Ultra Filtration (U.F. System)
b). Reverse Osmosis (R.O. Plant)
Packaged Sewage Treatment Plant (PSTP) is housed in specially designed and highly durable FRP tank. These tanks are compact which can be utilized in a decentralized manner at any location, either it’s underground or above the ground.
The Packaged STP is designed to bring the treated sewage parameters (BOD, COD, TSS, TN etc.) below the permissible limit which is stipulated by the Pollution Control Board. MBBR technology is used in this system.
The influent sewage water passes through a bar screen to remove all the large objects like cans, rags, sticks, plastic packets etc. which are carried in the sewage stream.
a. Anaerobic Zone
The first stage of PSTP is an oxygen-depleted anaerobic zone in which the solids in raw sewage gets settled while allowing the scum to float on the surface. It is a zone in which the settled sludge is stabilized by anaerobic digestion.
b. Anoxic Zone
The sewage then enters the anoxic zone in which denitrification of the wastewater stream is accomplished by returning the activated sludge from the final sedimentation zone to the anoxic zone; wherein dissolved oxygen levels are maintained approximately as 0.2 to 0.5 mg/l. In the denitrification process, anoxic microbes break down to the existing nitrates, this results in the release of inert nitrogen gas into the atmosphere.
c. Aeration Zone
The sewage from solid separation zone flows into the aeration zone. Air is diffused with the help of air blowers which encourages the growth of bacteria cultures in and around the floating plastic media added in the aeration zone. The MBBR media provides the extended surface area for the growth of microorganisms.
d. Sedimentation Zone-
The next step of treatment involves the sedimentation zone where organic waste is settled. The settled waste in the bottom of the tank is pumped back to the anoxic zone as a return sludge, which is done to ensure that the quality of effluent must pass the stipulated sewage parameters.
3.Tertiary Treatment System:
The secondary treated sewage is then passed through the Pressure Sand Filter and Activated Carbon Filter for the removal of suspended solids (TSS), colour, and odour. The treated water is then disinfected using sodium hypochlorite before it is reused.
WATER TREATMENT SYSTEMS
The water treatment necessary for Industrial, Residential, Gated Communities, and Commercial etc can be looked into by chemical or physical treatments whatever the case might be. The general adopted systems are:
A) SAND BED FILTERS
B) DUAL MEDIA FILTERS
C) PRESSURE SAND FILTERS
D) ACTIVATED CORBON FILTERS
E) SOFTENER PLANTS
G) ULTRA FILTRATION SYSTEMS
H) R.O. SYSTEMS.
A) SAND BED FILTERS/DUAL MEDIA FILTERS/PRESSURE SAND FILTERS:
To trap the suspended particles and to reduce Turbidity etc., Sand Bed Filters / Dual Media Filters are commonly used both in Residential and Industrial for all types of Sewage and Effluent Treatments. This process can be slow, rapid or pressurized flow of the Influent into these filters.
B) SOFTENER PLANTS:
The Softener Plants are used to remove hardness present in the water due to Calcium and Magnesium based Salts.
Our company has so far installed Softeners of various capacities to remove hardness for Industries for its Boiler applications or process applications or non-scaling of pipelines or containers etc.
We have expertise in Designing, Manufacturing, Installing & Commissioning of R.O. Systems of bigger capacities up to 10,000 Lts/hr etc.
We have already installed the R.O. Plants for Industrial, Residential, and Commercial in and around Hyderabad, A.P.
Off late Automation is playing a vital role to cut down the operating cost with respect to reduction in manpower, electrical power, consumables etc.
Our company attained expertise in automation of:
A) STP (Sewage Treatment Plant)
B) WTP (Water Treatment Plant)
C) ETP (Effluent Treatment Plant )
D) EXTERNAL PLUMBING
*Case studies are provided for your reference upon enquiry.
Safety of human and property is very vital in day to day living. FireFighting is
essential in dealing with all mishap’s caused due to fire.
Our company executes on Turnkey basis with NBC norms for the complete range like:
A) Hydrant system
B) Pumping system
C) Sprinkler system
D) Alarm system..etc.
The hydro pneumatic system consists of a pressure pump and a pressure tank. The pressure tank consists of a rubber bladder surrounded by pressurized air. Water being a non-compressible fluid, pressurized air is used.
