By Heather Jennings, PE Today we are going to focus on nitrifiers, those wastewater treatment autotrophs that get energy from oxidizing ammonia. (Autotrophs are microorganisms that produce complex organic compounds using inorganic carbon from simple substances as a food source.) Oxidizing ammonia is a fancy way of saying ripping off hydrogens to stick oxygens onto
Way too many growers are wasting agrochemical products or making products ineffective or even dangerous due to improper mixing. In Episode 8 of The Huma Gro Farmer Podcast we interview Dr. Mojtaba Zaifnejad, BHN Senior Director of Field Research and Technical Services, and Mr. Jason Garcia, BHN Florida Sales Manager and Agronomist, regarding best
Fifty years ago today, on April 22, 1970, 20 million Americans took to the streets to protest environmental destruction and to celebrate the wonders of Planet Earth. The basic message was that we had to find new ways to live our lives, raise our food, and conduct our businesses that were environmentally friendly and sustainable—that

By Heather Jennings, PE, Senior Project Engineer for Probiotic Solutions® I was attending a wastewater conference and overheard an operator talking about how a drug bust turned his lagoon orange and almost put him out of compliance with his permit. At another location, I was told that the city I was visiting had been hit by
By Jael Batty The UN warns that by 2030, over half the world will be water-stressed, affecting food production and increasing exposure to waterborne disease. There is enormous potential in directly recycled wastewater. Unfortunately, attempts at wastewater recycling have historically been shot down by the public.1 Thus, most treated wastewater is dumped into oceans and
While controversial among activists and consumers, land application of septic and sewage sludge is not a new practice. Farmers have been land-applying raw sewage––at one time called "Night Soil"––to fields and crops for centuries.
A plastic manufacturer in Taiwan needed a new process to efficiently treat elevated incoming chemical oxygen demand (COD) to comply with stringent EPA regulations for effluent discharge. The plant is an activated sludge treatment system with an influent of approximately 2,000 cubic meters per day (CMD) which is equivalent to approximately 530,000 gallons per day
A citrus plant struggled with poor settling in the clarifier of its wastewater treatment, which caused the sludge blanket to remain high. Even at a low flow rate of 1.2 million gallons per day (MGD), the high sludge blanked allowed less than 18” of free board. The slightest flow increase caused solids to carry over
