Maintenance shutdown planning: stock, staff and standby doses
The plant goes down for five days; the sump does not. How to forecast shutdown inflow, stock polymer, name a standby operator and avoid the April overflow.
Leachate recirculation and what it does to solids loading
Recirculation cuts volume but raises TDS, fines and polymer demand. Four numbers to track and the operating rules that keep the dose predictable.
Pump spares strategy: which failure stops the yard
Rank pump spares by hours lost, not price. A practical stock list for a 100 m3/day leachate pad and the labelling habit that prevents a nineteen-hour stop.
Wet season versus dry season: two dose schedules, one site
One dose rate cannot cover both seasons. How wet and dry leachate chemistry differ, when to switch schedules, and what the June batch failure looks like.
A winter storm inflow surge: dosing against the rain gauge
A winter storm can triple leachate volume in a day. How to read the rain gauge, predict sump rise and stage polymer before the peak instead of during it.
What a Landfill Operator Checks Before Tipping a Gelled Load
Thirty seconds at the gatehouse decides whether your load tips. The four checks applied first, why over-dosing can fail a load, and how to build one that passes.
