Sewage Treatment Plant

We design, manufacturing Erection & commissioning of Sewage treatment plants for varied industries on turnkey basis in Chennai Tamilnadu India. We Design, Fabricate, Supply, Erect and Commission Sewage Treatment Plants (STP) for treating sewage generated by Industry, large colonies, Hotels, Hospitals, IT Parks and commercial buildings. 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.

AS per requirement

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.

Sewage and its Treatment Sewage is the spent water stream generated after use of fresh water in various activities of domestic, non-industrial nature, such as washing water, food preparation waste, laundry waste, and other waste products of normal living including sanitary Waste water. This sewage, if discharged untreated into water bodies, leads to their pollution and degradation of the most valuable resource of all – water. Sewage hence needs to be treated before its discharge and after that, can also be reused for some applications such as toilet flushing and gardening etc. Sewage Treatment Plant and its Process A Sewage Treatment Plant, commonly called as STP, is domestic waste water treatment plant used to achieve the end of making spent water pollution free before its disposal or re-use. It mainly consists of 3 stages: Preliminary, Biological and Tertiary: Depending upon the intended end use of treated water, a fourth stage of advanced treatment may also be considered. Preliminary Treatment Consists of screening and removal of oil and grease (if applicable) for which mostly physic mechanical processes are used. The purpose of this stage is to remove external large solid/ floating material as well as floating oils in the stream so as to make it suitable for biological treatment stage. Biological Treatment Is the stage where organic impurities in the waste stream are treated by the use of microbial organisms. These organisms metabolize the pollutants as their food either in presence or absence of air, called aerobic or anaerobic processes respectively. The sludge so generated is settled and ultimately flushed out from the system. It is thus, the Biological Reactor which is the HEART of any Sewage Treatment Plant and it is on the basis of the same, that all processes are classified into different groups. Other than this, different stages of all processes are similar. Tertiary Stage consists of disinfection and filtration. Disinfection is required for the purpose of removal of any residual harmful bacteria in the water stream. Filtration is used to remove any TSS in the stream and also for polishing the treated water clean.
