How FRP Bio Digester Interconnection Works
FRP Bio-Tank Interconnection — 12KL System, Chettinad Hospital, Kalpakkam FRP TANK WORKS CASE FILE 12KL–CHT–KLP Installation Case Study Four tanks. One system.12KL of interconnected capacity. A modular FRP bio-tank network delivering hospital-grade wastewater treatment at Chettinad Hospital, Kalpakkam — built from four reusable 3KL units instead of one fixed structure. Site Chettinad Hospital, Kalpakkam Required Capacity 12 KL Configuration 4 × 3 KL, Interconnected Material FRP (Reusable) FIG. 00 — TANK BODY IN EXCAVATION, KALPAKKAM SITE INTERCONNECTED MANIFOLD RUN — COMMON INLET / OUTLET HEADER TANK 01 3 KL TANK 02 3 KL TANK 03 3 KL TANK 04 3 KL TOTAL = 4 × 3KL = 12KL 01 — DESIGN RATIONALE Why interconnect four tanks instead of casting one 05 FACTORS 01 Modularity Smaller 3KL units move easily through restricted hospital access roads and tighter installation footprints. 02 Reusability Each 3KL FRP tank is an independent module — redeployable or relocatable without discarding the whole system. 03 Redundancy Any single tank can be isolated for inspection or servicing while the other three keep the system running. 04 Load Distribution Spreading 12KL across four units reduces structural stress versus one oversized tank. 05 Faster Install Pre-fabricated units are interconnected on-site in a fraction of the time a custom-cast tank would need. 02 — TECHNICAL REFERENCE Interconnection keywords & components Manifold System Common inlet / outlet header connecting all four tanks into one hydraulic circuit Inter-tank Piping FRP / PVC lines linking each 3KL unit to the balancing pipeline Balancing Pipeline Equalises flow and pressure so no single tank is overloaded Reusable Modules Each tank functions as a standalone unit, redeployable elsewhere if needed Capacity Expansion 3KL × 4 = 12KL, expandable in further 3KL increments Joint Sealing Airtight interconnection joints rated for continuous bio-digester service Fittings Anti-corrosive FRP fittings suited to hospital wastewater composition 03 — INSTALLATION SEQUENCE How the 12KL system works 05 STEPS 01 Position the four 3KL tanks Units are placed at the designated site within the hospital premises, arranged for shortest pipe runs. 02 Interconnect inlet & outlet Tanks are linked using FRP/PVC piping so wastewater flows sequentially or in parallel across all four units. 03 Fit the common header A shared header line balances flow and pressure so no single tank carries excess load. 04 Commission the network The interconnected system is tested end-to-end and brought into continuous service. 05 Reserve for future expansion Additional 3KL tanks can be added to the same network later without replacing existing infrastructure. 04 — SITE RECORD Installation gallery 02 PLATES FIG. 01Tank body positioned in excavation — riser vents & inlet/outlet stubs visible FIG. 02Full trench view — interconnect loop & multi-chamber risers along the top 05 — OUTCOME Benefits for a healthcare facility Hygienic, leak-proof containment suited for hospital wastewater streams. Space-efficient layout using four smaller tanks instead of one bulky structure. Lower long-term cost from the reusability of individual tank units. Easy scalability — capacity grows in clean 3KL increments as needed. Quick deployment with minimal civil work versus concrete tank construction. Corrosion resistance and long service life from FRP construction. Planning a similar 6KL, 12KL, or custom-capacity system?
