Trity Environ Solutions is a trusted grey water treatment plant manufacturer in India, engineering MBBR, MBR, and SBR based systems that recover wastewater from sinks, showers, and laundry for reuse in flushing, irrigation, and cooling. Our plants are built around your actual source composition, with pan India installation support.
A large residential complex or hotel spending 80 to 150 rupees per kilolitre on tanker water is often simultaneously draining hundreds of kilolitres of grey water, wastewater from sinks, showers, and laundry, straight into the sewer every day. Grey water typically accounts for 50 to 70 percent of a building's total wastewater flow, and it's cleaner and more consistent than sewage. A properly engineered grey water treatment plant recovers a meaningful share of it for flushing, irrigation, and cooling, with savings that show up directly in the monthly water bill rather than staying theoretical.
Grey water isn't uniformly "clean," though, and BOD can range from 50 to 250 mg/L depending on the source, which is why proper site characterisation before design matters more than most buyers expect.

Buildings don't generate grey water uniformly, and morning shower and laundry peaks can push 3 to 4 times the average hourly flow through a system for a couple of hours at a time. An undersized equalisation tank can't buffer this surge, causing hydraulic shock to the biological stage that takes days to stabilise. Trity Environ Solutions consistently sizes equalisation volume above the bare minimum calculation, particularly for residential projects where morning loading spikes are severe and predictable.
Hotel laundry rooms generate high surfactant loads that produce foam in equalisation and aeration tanks if the system isn't designed with a defoaming arrangement, a detail that gets missed in template-based designs. Separately, MBR membranes need disciplined cleaning schedules, since a few neglected weeks lets transmembrane pressure climb and flux drop, leading to replacement costs of 3 to 6 lakh rupees well ahead of design life. Trity Environ Solutions specifies both defoaming provisions and written membrane cleaning protocols upfront, backed by an Annual Maintenance Contract.

Biological tanks in a grey water system generate sludge, less than a full STP but consistently, and if nobody withdraws it regularly, mixed liquor suspended solids climb and treatment efficiency drops. Trity Environ Solutions integrates sludge dewatering equipment into the plant design from the outset, since dewatered sludge is far easier and cheaper to dispose of than liquid sludge left to accumulate. Kitchen washing sinks feeding into the same system also need a grease trap or DAF pretreatment upstream, since unremoved grease clogs the biological stage quickly.
Plastic biofilm carriers treat grey water in a compact footprint, forgiving of load fluctuations, a practical choice for sites without full-time operators.
Combines biological treatment with membrane filtration for the highest treated water quality, suited to cooling tower reuse where consistent output matters most.
Batch cycle operation gives flexibility for intermittent or variable flow, well suited to hotels and educational institutions with irregular daily patterns.
Grey water treatment integrated with a Zero Liquid Discharge system for facilities pursuing complete water recovery and zero freshwater discharge on site.
A well-designed, consistently maintained system typically performs reliably for 15 to 20 years, though UV lamps need annual replacement and MBR membrane modules generally last 5 to 8 years with proper cleaning.
Most residential and commercial buildings can replace 30 to 55 percent of daily freshwater consumption with treated grey water, depending on how many reuse applications are connected.
It depends on state, project type, and size, with many states requiring on-site treatment for residential complexes above certain unit thresholds and commercial establishments beyond defined discharge volumes.
No, grey water treatment, even with MBR and UV disinfection, does not produce potable water. Treated output is suitable for flushing, irrigation, cooling, and cleaning only.
A 10 to 25 KLD system on a ready site typically commissions in 4 to 6 weeks, while larger systems with significant underground civil work may take 12 to 18 weeks.
For a 50 KLD MBBR-based system, monthly operating costs typically range from 8,000 to 18,000 rupees, covering power, chemicals, and routine maintenance, with MBR systems running slightly higher due to membrane cleaning costs.
