Stimulation Using Hydraulic Fracturing

The process involves pumping ,fluid, into a formation under sufficient pressure to create fractures in the rock matrix; allowing oil or gas to ,flow, through the fractures more freely to the wellbore. By creating new pathways, hydraulic ,fracturing, can exponentially increase oil and gas ,flow, to the well.

Biological nitrification is the microbe-mediated process of oxidizing ammonia to remove nitrogenous compounds from wastewaters. Domestic sewage typically contains 20 to 40 mg/L of ammonia nitrogen (NH 4- N). Organic matter containing nitrogen, e.g., protein and nucleic ,acid,, also biodegrades to release ammonia.
