MBR (Membrane Bioreactor) technology combines biological treatment with membrane filtration to produce superior quality effluent. Learn why MBR is becoming the preferred choice for wastewater treatment. How MBR Technology Works MBR systems use membrane modules (typically ultrafiltration or microfiltration) to separate biomass from treated water: Biological degradation of organic pollutants...

Designing an effective wastewater treatment plant requires careful planning, engineering expertise, and understanding of local regulations. This comprehensive guide walks you through the key considerations. 1. Site Assessment and Capacity Planning Before starting the design, conduct a thorough site assessment: Determine average daily flow rate Identify peak flow conditions Analyze...

Parshall flumes provide accurate flow measurement for wastewater and stormwater in open channels, essential for process control and compliance monitoring. What is a Parshall Flume? A Parshall flume is a standardized open-channel flow measurement device with a converging inlet, throat, and diverging outlet. Flow rate is determined by measuring water...

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...
