WATER & WASTEWATER TREATMENT · CHENNAI

Every effluent gets the treatment it actually needs.

Watertekniks designs and builds sewage, effluent, and water reclamation systems — ceramic and spiral RO, ultrafiltration, ozonation, and zero-liquid-discharge distillation — sized to your volume, your budget, and your discharge standards. Engineered for a sustainable future.

WHO WE ARE

Engineered for a sustainable future

With over two decades of process engineering experience in water and wastewater treatment, Watertekniks was established in July 2019, engineering the appropriate treatment train for each client: biological (aerobic/anaerobic, attached- or suspended-growth) or non-biological (physico-chemical) processes, selected on influent characteristics and discharge objectives rather than a default standard.

Our strength is taking a different approach rather than following the crowd. Based on the volume of effluent, we decide between full treatment or direct evaporation — whichever gets the customer there without relying on fossil fuels.

That means treatment processes with a smaller footprint, lower energy use, and lower capex and opex — including retrofits that reduce the load an existing biological or tertiary treatment system sends on to evaporation and distillation, saving significant energy and operating cost.

TECHNOLOGIES

Twelve systems, one job: cleaner water out

Every plant we build draws from the same core toolkit — combined differently depending on your water, your standards, and your site.

Watertekniks ceramic ultrafiltration module, and assembled membrane rack

Ceramic ultrafiltration

High flow rate, small footprint. Tubular modules for oily water and complex effluents; flat-sheet modules for high-flux applications — non-biological submerged ultrafiltration, or submerged ultrafiltration (rather than conventional MBR) in biological treatment. Trial skids available in both tubular and flat-sheet ceramic configurations.

Watertekniks fully automatic spiral wound reverse osmosis skid

Spiral wound reverse osmosis

Fully automatic RO for clear water, treated sewage, and treated effluent reclamation.

Watertekniks disc tube reverse osmosis installation

Disc tube reverse osmosis

For direct effluent treatment and high-TDS waters. Staged with or without pre-treatment, recoveries can reach up to 95% with minimal brine discharge to downstream evaporation systems.

Watertekniks nanofiltration skid

Nanofiltration

Selective pre-treatment ahead of disc tube or spiral wound RO — rejecting divalent ions and larger organics while passing monovalent salts, protecting downstream membranes and lifting recovery.

Watertekniks pre-fabricated biological sewage treatment plant, installed on site

Pre-fabricated STP/ETP — biological

Sewage and effluent treatment plants built around a biological treatment method.

Watertekniks pre-fabricated non-biological effluent treatment tank

Pre-fabricated STP/ETP — non-biological

The same plants, built around a non-biological method — sized to the client's effluent volume.

Watertekniks energy-efficient surface aerator, unit and in-tank operation

Energy-efficient aeration

Microbubble aeration and high-efficiency diffusers tuned for oxygen transfer efficiency, cutting blower energy per kg of BOD removed in activated sludge and lagoon systems.

Watertekniks pressure sand and activated carbon filtration vessels

Pressure sand, glass media & activated carbon filtration

A polishing stage for clear water, treated sewage, and treated effluent.

Watertekniks fully automatic ultrafiltration skid

Fully automatic ultrafiltration

Clear water and effluent reclamation, available in in-to-out or out-to-in configuration.

Watertekniks electrodeionization (EDI) skid

Electrodeionization (EDI)

Continuous, chemical-free demineralization that polishes RO permeate to high purity without acid/caustic regeneration.

Watertekniks ozonator disinfection unit

Ozonators

Water disinfection, plus colour, odour & COD removal.

Watertekniks automated vacuum distillation system

Automated vacuum distillation

For effluents heading toward minimal or zero liquid discharge, without fossil-fuel evaporation.

R&D · NEXT-GENERATION GAS INFUSION

Alongside our core systems: a nanobubble trial skid

Our latest work pushes dissolved gas transfer further — a compact, skid-mounted nanobubble system built to trial directly on real site water.

Conventional aeration bubbles rise and burst at the surface within seconds, releasing most of their gas before it ever dissolves. Nanobubbles — under 200 nanometers across — are small enough that buoyancy barely acts on them, so they stay suspended in the water column for hours to days instead of seconds, transferring far more gas per unit of energy spent.

THE SKID

One skid, five stages, start to finish

Gas generation, gas concentration, compression, circulation, and nanobubble infusion — combined into a single deployable unit.

01GAS
Oxidation & disinfection

Ozonator

Generates ozone (O3) on demand from the incoming air or oxygen feed — the oxidizing gas that drives disinfection and breaks down organic contaminants once infused into the water.

02GAS
Feed gas supply

Oxygen concentrator

Draws in ambient air and separates a concentrated oxygen stream, giving the system a richer feed gas than raw air for both ozone generation and direct dissolved-oxygen boosting.

03GAS
Pressure supply

Air compressor

Supplies pressurized air where the process calls for it, keeping gas delivery to the generator stable.

04FLUID
Circulation

Pump

Drives water through the nanobubble generator at the flow rate and pressure the shearing process needs, then recirculates or discharges treated water.

05OUTPUT
Where it all converges

Nanobubble generator

Shears the incoming gas stream into sub-200-nanometer bubbles and infuses them directly into the water flow — the stage every upstream component exists to feed.

WHERE IT APPLIES

Nanobubble infusion, put to work

Aeration & DO boosting

Raising dissolved oxygen in aeration basins and lagoons with less blower energy spent on gas that never dissolves.

Ozone disinfection

Infusing ozone deep into the water column instead of losing it to off-gassing at the surface.

Effluent & reuse treatment

Supporting effluent treatment and reuse streams that depend on sustained dissolved-gas contact time.

Odor & H2S control

Oxidizing odor-causing compounds at the source, at headworks and lift stations.

Aquaculture oxygenation

Holding higher, more stable dissolved oxygen in ponds and tanks without the turbulence coarse aeration creates.

Pilot & trial deployments

A self-contained skid built to be trialed on real site water before anyone commits to a permanent installation.
