Opening and Closing Big Valves Within a Wastewater Treatment Plant

For townships and cities that maintain a central sewer system, it is important to treat the wastewater and make it safe for release back into the environment. The mechanical operations of flow control valves, actuators, circulation tanks and gates help treatment plants manage the flow of wastewater during this process.

Today, more Americans than ever believe in environmental protection. After all, there is no doubt that improper waste management leads to contamination and the spread of diseases. This makes it all the more important for municipalities to ensure they have full control over the flow of all substances in and out of these treatment plants.

Mistakes can be costly and valve failure must be prevented. This is just one of the many reasons so many municipalities rely on electric actuators over hydraulic or pneumatic actuators.

A Brief History of Waste Treatment

In 1948, Congress signed the Federal Water Pollution Control Act to address the contamination of water supply systems. As awareness grew in America, it created enough momentum to pass the 1972 Clean Water Act. Not only do homes and businesses need to abide by the 1972 law, but municipalities need to as well.

Since then, there have been several amendments to strengthen the law and to provide more leeway to the EPA to implement programs aimed at solving pollution problems. Wastewater treatment plays a significant role in this goal.

The Needs of the Treatment Plant

Municipality maintenance crews are beholden to check and maintain the integrity of the rotary actuators for valves and gates that help to manage the flow of water and wastewater sludge. Periodic testing is mandatory to help keep the system stable. The flow of wastewater through primary and secondary clarifiers must not be impeded upon and the cleaning of debris and grit screens daily ids a must. The chlorination process works best when the majority of heavy particulates are removed before chlorination. Often the controls for butterfly valves is what impedes water flow, especially if older hydraulic equipment is not well maintained. These pages do a good job defining what is a hydraulic actuator and what is a pneumatic actuator.

Each treatment plant is different and should be evaluated as an independent unit. However, all treatment plants prioritize the release of safe substances back into the environment well after the dichlorination process and final filtering with sodium bisulfate. Problems occur when there is faulty equipment in the flow of water and sludge water. This flow requires the use of heavy-duty valves built to handle wastewater that may also hold suspended solids and reliable actuators for wastewater treatment applications. The valves, in turn, need the right controls to ensure maximum precision.

The Importance of Precision

When it comes to wastewater management, engineers and operators must be able to maintain the controls for these butterfly valves and wastewater gates. Selecting a good valve actuator manufacturer to evaluate the needs before selecting the right equipment can help. Opening and closing these big valves requires not just the right equipment from a reputable valve actuator manufacturer to stand behind their equipment.

Even a small glitch can wreak havoc. For shut off valves that workers may control manually, opening and closing at the wrong time may not only lead to contamination but valve damage.
