Screenings washers reduce the organic content and volume of captured debris, reducing disposal costs and odors. What are Screenings? Coarse debris removed by bar screens: rags, plastics, paper, food waste, and other solid materials. Why Wash Screenings? Reduce organic content (BOD) in screenings Reduce volume and weight Minimize odor problems...

Chemical coagulation and flocculation are essential processes for removing suspended solids, colloidal particles, and some dissolved contaminants. Coagulation vs. Flocculation Coagulation Chemical addition (coagulant) destabilizes particles through charge neutralization. Fast mixing required. Flocculation Gentle mixing allows formed microflocs to collide and aggregate into larger, settleable flocs. Coagulants Aluminum sulfate (alum):...

Oil water separators are essential for removing free oil and grease from industrial wastewater before biological treatment. Types of Oil Water Separators API Separators American Petroleum Institute design. Uses gravity separation with long retention time. Handles high oil loads. CPI (Corrugated Plate Interceptor) Inclined plates increase effective settling area. More...

Moving Bed Biofilm Reactor (MBBR) technology combines activated sludge efficiency with biofilm reactor simplicity for compact, efficient wastewater treatment. How MBBR Works Small plastic carriers with biofilm grow inside an aerated tank. Carriers are retained by a screen at the outlet. No sludge recycling required. Key Advantages High efficiency: High...

Automatic samplers provide representative wastewater samples for laboratory analysis, process monitoring, and regulatory compliance. Why Use Automatic Samplers? 24/7 sampling capability Representative composite samples Reduce labor requirements Sample integrity preservation Data for process optimization Types of Automatic Samplers Time-Proportional Samplers Collect samples at regular time intervals. Good for flow-proportional calculations....

Tertiary treatment provides advanced polishing of wastewater to meet stringent discharge standards or enable water reuse. Why Tertiary Treatment? Secondary treatment alone may not meet standards for: Nutrient limits (nitrogen, phosphorus) Suspended solids Pathogen reduction Water reuse quality Tertiary Treatment Technologies Filtration Multi-media filtration, sand filtration, or membrane filtration removes...
