RRR ENVIRO SYSTEMS offers a wide variety of options for purification of sewage water from different sources either from toilet kitchen , washbasin etc,.. .
Source of Domestic sewage Water
Wastewater comes from ordinary living processes: bathing, toilet flushing, laundry, dishwashing, etc.
It comes from residential and domestic sources.
Wastewater is broken into two categories, depending upon the source.
1. Gray water: Gray water is from showers, baths, whirlpool tubs, washing machines, dishwashers and sinks other than the kitchen sink.
2. Black water: Black water is from toilets and kitchen sinks.
Characteristics of domestic sewage
We are offering sewage treatment plant to our clients. Designed under the guidelines of astute experts, this plant is accredited at schools where water treatment is highly accredited for water drainage and sewage. Perfectly designed in compliance with the international quality standards, this plant is manufactured by making use of qualitative raw material that is sourced from valued vendors.
The raw effluent collected from different toilets and baths and floor washing etc. is allowed to flow into the collection pit cum grit chamber through a coarse screen and then allowed to flow to the next chamber.
From there the raw effluent (submersible) pumps will pump it to the reaction tank.
The biological process starts as the raw sewage it enters into the Packaged STP unit.
The first step is pre-aeration. Here the raw sewage is briefly aerated and allowed to over flow to contact aeration chamber. On the first impact with the contact media quoted with enzyme, the BOD load drops significantly. At contact aeration chamber, the waste is aerated, which helps grow MLSS (Mixed Liquor Suspended Solids). The MLSS overflows to sedimentation chamber for effective liquid â?? solid separation. The thick sludge is returned to the aeration chamber while the clear supernatant is allowed to flow out for disposal. As the sludge returns to aeration zone, it starts to get digested and tends to thin down. This is the specialty of this plant; it produces far less sludge as compared to any other sewage treatment plant.
The treated water may be discharged directly to any municipal drain without any further treatment or re-used after tertiary treatment, as per local regulations and re-use application.
Trusted by demanding customers like UN establishments, US Navy etc. due to the
Simplicity in design & performance
Toughness
Flexibility in seismic conditions compared to RIGID, CENTRALISED tanks.
Effective & satisfactory performance in unattended / unmanned operations
Nuisance freeness due to
no-odour
NO-SLUDGE REMOVAL conditions so no daily hindrance of manual sludge cake removals from filter press.
No-visible dirty water, as treatment takes place in sealed FRP tanks. So unpleasant visions are not created even when someone looks out from upper floors.
NO MOISTURE CREATED FROM OPEN SURFACES OF DIRTY WATER AROUND THE STP, WHICH USUALLY CAUSE SKIN DISEASES.
Powered by biological treatment process by means of engineered bacteria, these plants do not need daily dosage of harmful and expensive chemicals to operate.
Compact size, so less footprint. Further constructions can be easily done from above these tanks which help in better land utilization.
HINDRANCE FREE AS NO NEED FOR REGULAR DE-SLUDGING
Lesser number of rotating parts. No sludge recirculation pumps, filter press etc. required. Hence lesser energy consumption also.
Electroplating wastewater include the pretreatment rinsing wastewater, plating rinsing wastewater. And the principal pollutants are heavy metal ion .
1.1 Up-to-standard discharge technology The emission of waste water which contains heavy metal ions such as Cr, Cu and Ni must meet the local requirements by adopting the means of Physical and Chemical Reaction + Sequencing Batch Precipitation + Ion Exchange + Compulsory Filtration to reach the standard.
1.2 Electroplating wastewater reuse technology
Electroplating wastewater reuse technology means to add reclaimed water reuse system and reuse system on the basis of standardized discharge technology. The effluent can meet reclaimed water reuse standards(such as cleaning).
1.3 Electroplating wastewater zero-discharge technology MVR evaporator Working principle: MVR evaporator will increase the energy of secondary steam by using compressor, and will take advantage of the secondary steam with improved energy to recycle the potential heat of secondary steam. Specifically: Increase the pressure and temperature of the secondary steam generated by evaporator through the adiabatic compression in compressor, and after that, the steam will be fed into the heating chamber of evaporator (heat exchange system) as the heating steam, thus the potential heat of steam can be reused. The cold material will absorb the heat of non-condensable gas through preheating exchanger before being sent into evaporator, so the temperature of the cold material will increase, meanwhile, the condensate can be cooled by this material. This can further improve the utilization ratio of heat.
