Running an ETP or STP is not a set-and-forget operation. Many industries continue using the same chemicals and dosages for years - even when the output quality is clearly declining. Here are 5 signs your wastewater treatment system is failing, and exactly what to do about each.
What it looks like: Suspended solids are still visible in the effluent after clarification. Settling time has increased.
Why it happens: Wrong polyelectrolyte grade, under-dosing, or the incoming wastewater composition has changed.
Fix: Conduct a jar test with different polyelectrolyte grades. Anionic series polymers from BIGROCK FlocPro™ are specifically engineered for rapid floc formation and efficient clarification in high suspended solid environments.
What it looks like: Filter press or centrifuge output is wet, heavy, and difficult to handle. Disposal costs are rising.
Why it happens: Poor solid-liquid separation due to incorrect polymer charge density.
Fix: Switch to a cationic polyelectrolyte designed for superior sludge dewatering. BIGROCK FlocPro™ Cationic Series is engineered for exactly this - enhanced solid-liquid separation performance.
What it looks like: Some batches pass pollution board standards, others don't. Output turbidity varies day to day.
Why it happens: Inconsistent chemical quality from your supplier, or fluctuating incoming wastewater load.
Fix: Consistent polymer quality is non-negotiable. Bigrock Chemicals India maintains strict batch-to-batch quality control to ensure the same performance every time.
What it looks like: Filter cloth chokes frequently, requiring cleaning or replacement every few weeks.
Why it happens: Incorrect polymer dosage leading to poorly formed flocs that blind the filter media.
Fix: Optimize dosage through jar testing. Even a small adjustment - 10-15% more or less polymer - can dramatically improve filter press performance.
What it looks like:You're using more chemical every month but the results are the same or worse.
Why it happens: Low-quality polyelectrolyte with inconsistent molecular weight, or poor dissolution resulting in wasted product.
Fix: Powder polyelectrolytes, when properly dissolved, offer significantly better cost efficiency than liquid alternatives. BIGROCK FlocPro™ is high-concentration, meaning less product achieves better results.
