Engineering notes written from the plant floor, how we size, select and troubleshoot water and wastewater systems. No marketing; numbers you can check.
STP sizing, ETP estimator, cooling tower balance, RO recovery.
General standards, STP norms and reuse standards in one place.
62 terms, one line each.
India vs IFC vs EU vs US EPA treated sewage limits, with sources.
Printable STP, ETP and RO checklists (PDF).
Codes and guidelines we design to, and how local norms are handled.
What to send for a plant quote, with a one-page PDF.
Land, levels, power and permits to confirm before you order.
What to test and how to sample for plant design.
A practical guide to leachate treatment plant design, characterising leachate, choosing between MBR, DTRO, ammonia stripping and evaporation, sizing for monsoon flows, and what drives capital and operating cost per KLD.
FSTP design for small towns: estimating septage load from population and desludging cycle, land requirement, choosing between drying beds and mechanical dewatering, liquid treatment options, and what a co-treatment unit at an existing STP needs.
Zero liquid discharge operating cost explained: where the money goes in a ZLD train, why the evaporator size decides everything, and seven engineering measures, segregation, high-recovery RO, MVR, salt recovery, that reduce ZLD OPEX.
How a compliant purified water (PW) generation and distribution system is designed, pre-treatment, RO, EDI, UV, storage and loop, what USP/IP/EP require, how validation (DQ, IQ, OQ, PQ) is structured, and the recurring reasons PW systems fail audits.
A decision guide for STP technology selection, how MBBR, SBR and MBR differ in footprint, capital cost, power, operator skill and outlet quality; how to size an STP from occupancy; and the questions to ask any vendor before you buy.
