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.
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.
