Notes from the plant room.
Practical writing on industrial water treatment — sizing, recovery, effluent and the decisions behind a reliable plant.
Zero Liquid Discharge: from compliance cost to circular asset
ZLD has shifted from an optional environmental strategy to a condition of operating in India. Treated the right way, the same plant that satisfies the regulator can also pay part of its own way back.
India's industrial water reckoning: why reuse is now a board-level risk
Water demand in India is on track to outrun supply within this decade. For industry, that turns reuse from an environmental nicety into a question of whether a plant can keep running at all.
The energy line of an RO plant: cutting the kWh per cubic metre
In a reverse-osmosis plant, the high-pressure pump is where the electricity bill is written. Feed salinity, recovery and one piece of recovery hardware decide most of it.
Reading a brackish-water feed: recovery, TDS and the 2:1 array
Every RO design starts with a number the borewell hands you — feed TDS — and a target you set against it. The relationship between the two shapes the whole skid.
PFAS and the next wave of water regulation
The 'forever chemicals' have moved from research papers to enforceable drinking-water limits. The technologies that remove them are ones the water industry already knows well.
Textile effluent in Gujarat: colour, TDS and the road to ZLD
Dye-house effluent is among the hardest industrial water to treat — and among the most tightly regulated. In Gujarat's textile clusters, ZLD is now the cost of doing business.
Digital water: what CPCB's OCEMS mandate means for your plant
Real-time effluent data now flows straight from the outfall to the regulator's servers. For many industries, online monitoring has become as much a part of the plant as the treatment train itself.
Membrane lifecycle: fouling, CIP and getting years out of an element
Membranes are the consumable at the heart of an RO plant. How long they last — and how much energy they cost while they do — is decided by how you read fouling and time your cleans.
