Waste Water Treatment Solutions
Community modular systems
The Need:
Sceptic tanks overflow contains nitrate and phosphates and contaminates the ground water, with disastrous health effects.
Smaller communities require a solution as piping individual homes to a common waste water system is expensive.
In certain workers colony, which are temporary, as soon as the construction work is over, the need for waste treatment shifts to the next site.
The Benefits:
- Sanitation issues are handled and it is good for health.
- Ground water does not get contaminated.
- Pooling of resources as it is a community initiative and community initiatives succeed due to the emotive factor.
- Recycling of water ensures that water is conserved and this is a sustainable proposition.
- Shifting of the equipment to various sites according to requirements.
The Design Challenge:
The system should be mobile, modular, compact and automated.
The technology adopted can be user specific and the system should be able to be maintained easily. Technologies used can be MBBR /MBR /ASBR.
It could be mounted on a trailer and then moved from various settlements and treated centrally whereby the truck moves bi-weekly and pumps the sewage to the trailer.
The location should be so decided that treated waste water is close to the end usage like irrigation or for toilet flushing.

Health care
Health care requires various waste water effluent streams to be treated. Streams which require separate treatment are a) waste from labs/theatre, b) laundry waste is, c) kitchen waste and d) waste from the toilets/baths.
The Design:
Laundry waste is neutralized for Ph; waste from labs/theatres are disinfected before aeration; kitchen waste is segregated of its food waste and segregated of oil & water and waste from toilets/bathing are all treated via common aeration.
Technologies for biological and separation is based on what is required by the end client. Technologies of MBBR, MBR, SBR are adopted according to the needs of the market.
Settling systems wherever appropriate are followed
For tertiary treatment, advanced self-cleaning filtration systems or ultra-filtration systems are adopted.
Traditional disinfectant systems like dozing chlorine or chlorine dioxide or advanced dozing systems of copper silver ionization is followed.

Communities & Townships
The Need:
Communities and townships base their treatment on aggregation of waste water from various generating units, be it households or commercial units or community centres. New townships and communities have the issue of being unable to plan precisely as to the time of occupation of these units as the waste generated build up when the units of the community are inhabitated. These are gated properties or lay outs.
The Benefits:
- Staggered capex outflows
- Low maintenance costs even at low loads
- Technology suitability to low turndown ratios.
- Modular add on bring in flexibility
- Challenges of biological treatment handles effectively
The Design Challenge:
The biggest challenge is in our ability to be able to have a system functioning considering that the system has a staggered inflow as it depends upon 2 factors, staggered construction as well as staggered occupation of the construction.
Besides, another challenge lies in being able to keep the plant running well on the biological front when the loads are low. The way forward is to use an appropriate technology to handle low loads and a turn down ratio to suit the needs of the community.
Enzymes can be added to handle low biological loads in traditional systems. A modular approach can be used for capacity ramp ups.
Power and maintenance costs are critical and when the loads are low and the systems which work on low loads are MBBR /SBR.
If the occupancy is good straight away, one can look into a MBR system.

Technology Centres & Educational Institutions
The Need:
The waste water load from Educational institutions, commercial offices and technological centres typically run-on week days and there is no load on the weekends. This sudden deflation of the input to the waste water system results in difficulty to sustain the biological activity.
There is a need to reuse, recycle and avoid fresh water, especially for toilets and for greenery. The best way to conserve fresh water is to reuse waster.
Centralized kitchen will be a challenge as there will be peak production of oils and water needs to be segregated from the same.
The Benefits:
- Wide range of technologies can cater to it,
- Expertise in handling kitchen loads, a critical input for waste water design,
- Design handles low loads from toilets and high loads from kitchen,
- Treated water is kept fresh in the weekends by recycling,
- Advanced disinfectant for longer residual life,
- Water used back in cooling towers.
The Design:
Peak loads can be handled by ensuring there is adequate buffer capacity in the collection tanks as cooking and use of cafeteria/food courts will be on a batch process .
As there is no water for bathing and with high kitchen loads, the BOD/CODS will be high as there is no organic loading.
Food separation, oil and grease removal is critical. Besides, we need to design retention times well for biological load handling.
All technologies can be used and, in the process, we require to be able to have good turn down ratios for the low loads for the weekends.

Factories/Warehouses/Industrial centres
The Need:
Factories have a combination of effluents as well as domestic sewage to treat. Industrial waste oil finds its way too into the waste water treatment plant.
Industrial training centres /ware houses need the requirements to treat the waste generated from the warehouse and logistics team. In a warehouse set up, the activity is 24 x 7, 365 days and requires a steady flow to be treated round the clock.
There would be centralized kitchens too and that would need an appropriate treatment system of food segregation, water and oil removal.
Waste water has to be reused as per their ISO ratings as Recycle, Reduce and Reuse is the mantra for such systems.
Waste water will be reused for toilet flush and the rest for greeneries.
The Design:
The design of the system has to ensure adequate buffer of retention time.
Careful removal of food and segregation of oil and water from the kitchen should be handled.
Systems adopted can be MBBR/MBR/SBR /Extended Aeration as we are looking at optimum loads throughout the week for the logistics business.
The organic loads will be high as dilution is negligible because of lack of bathing water and high load from the kitchen.
Depending upon reuse for toilets or for greenery, the tertiary treatment can be decided of a dual media filtration or ultra-filtration.
The Benefits:
- Customised to client’s requirements of technology as expertise in different technologies,
- Long life non corrosive disinfectant,
- Ensure low operational expenses and good pay back,
- Automation to ensure equipment’s work well over the life cycle costs,
- Designed for high organic loads.

The Benefits:
- Wide range of technologies can cater to it,
- Expertise in handling kitchen loads, a critical input for waste water design,
- Design handles low loads from toilets and high loads from kitchen,
