Troubleshooting Common Wastewater Treatment Problems: Foaming, Bulking Sludge, and Turbid Effluent
Field guide to troubleshooting common problems in activated sludge wastewater treatment: foaming (startup, Nocardia/Microthrix, surfactant slug), filamentous bulking, turbid effluent, rising sludge, ammonia breakthrough, and odor. Includes SVI thresholds, SRT and DO targets, a filament-identification table, and immediate versus long-term corrective actions.
Rural & Small Community Sewage Treatment: Which Process Fits Your Community?
A practical guide to selecting wastewater treatment processes for rural and small communities. Covers decentralized systems, underground plants, and disinfection options for populations under 10,000.
Slaughterhouse Wastewater Treatment: Engineering Solutions for High-FOG, High-COD Effluent
Engineering guide to slaughterhouse and meat processing wastewater treatment—addressing extreme FOG, blood, and COD loads with proven physical-chemical and biological solutions.
Breaking Down Wastewater Treatment Operating Costs: Energy, Chemicals, and Labor
Industrial wastewater OPEX typically splits across energy (25-40%), chemicals (15-30%), labor (20-35%), sludge disposal (10-25%), and maintenance (5-15%) at 50,000-500,000 gpd. Secondary biological treatment often costs $0.25-$1.00 per cubic meter; MBR or tertiary polishing can reach $0.60-$1.50 per cubic meter. Aeration, dosing control, and sludge cake dryness are the fastest levers for 15-30% OPEX cuts within 6-12 months.
Online Monitoring + Cloud Platform: How SMEs Can Run Wastewater Plants with Minimal Staffing
Discover how small and medium enterprises can leverage online monitoring and cloud-based platforms to operate wastewater treatment plants efficiently with reduced staffing requirements.
Municipal Wastewater Plant Upgrade: A²/O Process Enhancement with Advanced Tertiary Treatment
How to upgrade aging municipal wastewater treatment plants using A²/O process optimization and advanced tertiary treatment—meeting stringent nutrient limits without rebuilding from scratch.
Contract O&M for Wastewater Treatment Plants: Is Outsourcing Worth It?
Contract O&M outsources day-to-day wastewater plant operations while the owner keeps the assets. Savings are strongest at multi-shift plants when labor, chemicals, energy, and compliance risk are counted over five years. Use clear KPIs, capital boundaries, and exit terms, and prefer a hybrid model when you already have solid operators but thin process depth.
