Hydrocarbons in wastewater systems create operational challenges, including pH imbalance, increased chemical demand, and reduced biological activity. Formula 35HD is an advanced bacterial supplement engineered to break down hydrocarbons such as gasoline, diesel, oils, and grease — improving wastewater treatment efficiency and supporting optimal system performance.
