The Compactor Is Where a Firm Gel Works Against You
A compactor ram releases water from soft gel and sends it to the sump. Firmer dosing, longer set times, and a one-minute squeeze test before charging.
Pre-Mixing Versus Direct Application: Two Ways to Solidify Leachate
Your excavator driver can sprinkle powder into the pit from the bucket in about ninety seconds. Your neighbour built a mixing skid with a 3 m3 tank, a dosing pump and a lance, and spent three weeks commissioning it. Both are treating leachate with the same polymer. The question worth answering befor…
Inline Eductor or Batch Tank: Picking SAP Dispersion Equipment
Two plants run the same 25 kg bag of polymer through the same process and get different results. One produces a smooth gel in ninety seconds. The other spends twenty minutes chasing fish-eyes the size of peas that never fully hydrate and end up as soft lumps in the finished product. The difference i…
Cold Snap Solidification: What Freezes First and What to Do About It
The first hard frost of the year usually arrives overnight, and the first failure the next morning is not chemical. It is a 25 mm suction hose with a slug of frozen gel in it, and a crew standing around a pump that is running but moving nothing. What Freezes First In order: the lance tip, the suctio…
Picking a Pump and Hose for Polymer Slurry: The Four Numbers That Matter

It also settles, shears and sets, which is why that water pump is usually on the shelf with a burnt seal by the third week. The Four Numbers to Fix…
Hold Tank or 200-Litre Drum: Where the Batch Should Actually Happen
Two crews, same landfill, same polymer, same liquid. One runs 6 m3 batches in a steel hold tank with a paddle stirrer and fills drums from the bottom valve. The other drops powder straight into each 200-litre drum, pushes a lance in through the bung and recirculates. Both get acceptable loads out of…
