10 KLD STP – MBBR | RRR ENVIRO SYSTEMS

Process Summary

Raw sewage → Bar screen & O&G trap → Collection / Equalization (disc diffusers) → Raw sewage transfer pump (cutter/grinder option) → MBBR Aeration Tank (PP media + blower) → Secondary clarifier (RAS) → Clarified water tank → PSF → ACF → Hypo dosing → Final Treated Water Tank (Reuse: gardening, flushing, wash).

Design Basis (10 KLD)

Parameter	Value / Assumption
Design daily flow (Qd)	10,000 L/day
Operating hours	20 hours/day
Design hourly flow (Qh)	10,000 / 20 = 500 L/hr
Influent BOD (typical)	~300 mg/L
Target effluent	BOD < 30 mg/L after polishing

Tank Sizing & Equipment (Indicative)

Unit	HRT / Note	Volume (L)
Collection / EQ Tank (disc diffusers)	6 hours	500 × 6 = 3,000
Bar screen & O&G	0.5–1 hr	~500
MBBR Reactor (media filled)	6 hr HRT; media carriers in aeration	3,000
Secondary Clarifier	2 hr settling; RAS & wasting	1,000
Clarified water tank	buffer for PSF feed	~300
Final treated water tank	reuse buffer	~500
Sludge holding	intermediate	~500–1000

MBR Media Details (MBBR only)

Media Type: Virgin PP / HDPE bio-carrier
Shape: Cylindrical / K1 / proprietary carriers
Surface Area: 350–500 m²/m³ (typical)
Filling Ratio: 50–60% by reactor volume (as confirmed)
Advantage: Higher surface area → compact unit, better BOD removal & resilience to shock loads

Process Flow (detailed)

1. Toilets & waste → Bar screen (coarse removal) → O&G trap
2. To Collection / Equalization tank with disc diffusers (mixed & buffer)
3. Raw sewage transfer pump (cutter/grinder where required) → MBBR reactor (PP media + aeration via blower)
4. Secondary clarifier (settling). RAS (return activated sludge) pumped back to MBBR; excess sludge to sludge holding & dewatering.
5. Clarified water to Clarified Water Tank → Filter feed pump → PSF → ACF → Hypo dosing (online dosing) → Final Treated Water Tank.

Operation & Maintenance

Disc diffusers keep EQ tank mixed and reduce septicity.
Monitor DO in reactor (target DO 2.0–3.5 mg/L).
Check media movement & fouling; occasional carrier cleaning if required.
Maintain blower & perform periodic check of diffusers.
Wasting frequency for sludge controlled to maintain MLSS and biofilm health.
