Troubleshooting
Unstable Sludge Feed
Feed flow or concentration keeps changing
The press cannot hold steady results because the feed flow or solids concentration keeps swinging. Every change forces polymer and speed off their optimum, producing alternating wet and over-conditioned cake.

Causes and corrective actions
| Possible cause | Corrective action |
|---|---|
| Pulsating feed pump | Use a progressive-cavity or damped feed pump. |
| Fluctuating source concentration | Add a mixed buffer or blend tank. |
| Polymer not paced to flow | Pace polymer proportionally to measured sludge flow. |
| On/off rather than modulated control | Use level-based modulating control. |
