Verified Performance
Numbers competitors won't publish
Every Aquaxis PSTP is engineered to a measurable outlet quality, not vague promises. Here is the real inlet-to-outlet performance from our brochure, against typical sewage influent.
Standard PSTP removes 85–90% of pollutants. PSTP + TTP achieves >90% reduction for reuse-grade water.
| Parameter | Inlet Influent | Aquaxis PSTP | PSTP + TTP |
|---|---|---|---|
| pH | 6.0 – 8.0 | 6.0 – 8.0 | 6.0 – 8.0 |
| BOD (mg/L) | 250 – 300 | < 20 | < 10 |
| COD (mg/L) | 500 – 550 | < 100 | < 50 |
| TSS (mg/L) | 200 – 250 | < 50 | < 20 |
| TN (mg/L) | 40 – 50 | 10 | 10 |
| Fecal Coliform | 10,000 | < 100 | < 100 |
MBBR Technology
How our STP treats water in 6 stages
Moving Bed Biofilm Reactor (MBBR) treatment, a proven biological process that delivers consistent, reuse-ready output in a compact footprint.
Live MBBR aeration zone, aerobic bacteria on bio-media break down BOD & COD at an operational STP
1
Bar Screen & Inlet
Removes grit, large solids & floating material.
2
Solid Separation
Primary settling separates solids from liquid.
3
Anoxic / Anaerobic
Denitrification converts nitrates to nitrogen gas.
4
MBBR Aeration
Aerobic bacteria on bio-media cut BOD & COD.
5
Clarifier
Separates suspended solids & clarifies water.
6
Filter / UV (TTP)
PSF + ACF + UV for reuse-quality water.
✓
Treated Water
Reuse-ready outlet, beating CPCB norms.
FRP Underground Tank · up to 55,000 L
Built to Last
Real FRP products, factory-tested before dispatch
Every tank and plant is CNC filament-wound from fibre-reinforced plastic and clears a four-point quality check before it leaves our Gujarat facility, so it arrives 100% leak-proof and ready to install.
- Pneumatic leakage test, verified zero-leak before shipping
- Dimensional accuracy, held to ±1.5% tolerance
- Laminate strength test, flexural & barcol hardness
- Visual inspection, finish, fittings & connections

Why Aquaxis
Advantages no one else offers together
1
CNC filament winding
Computer-controlled winding gives universal thickness, consistent quality and structural precision in every tank.
2
¼ the weight of steel
FRP relative density is just 1.5–2 — about a quarter of mild steel — yet tensile strength is comparable to MS.
3
Food-grade & corrosion-proof
Isophthalic-resin FRP with a super-smooth, food-grade interior — safe for potable water, with no build-up.
4
MBBR + Smart IoT
Advanced MBBR treatment with live BOD/COD monitoring, alerts and remote ON/OFF control.
5
Factory-tested, every unit
Pneumatic leak, dimensional (±1.5%), laminate strength & visual checks before dispatch.
6
30+ years FRP expertise
Backed by 30+ years of FRP experience and the Japanese Johkasou decentralized approach. Make in India.
