Dosage control allows for treatment optimization

Unforeseen problems often lead to disastrous, expensive consequences in a wastewater treatment environment. However, technological advancements are giving operators the ability to predict problems before they happen in several facets of the treatment cycle. The S.sensing CS wastewater monitoring system from U.S. Water, a Kurita Co., offers innovative equipment to control and automatically adjust chemical dosage in wastewater treatment systems.

The automatic, chemical injection monitoring system is designed to control coagulant for optimum results. The monitoring system uses a laser-based technology and provides in-situ measurement of turbidity between the flocs. This enables the system to control product dosage at the inlet of the sedimentation basin, ensuring correct dosage of treatment, reduced labor costs and sludge disposal, consistent effluent quality and reduced surcharges.

“Utilizing technology to turn data into intelligent action is relatively young, and the benefits are just emerging,” says Michael Murdy, director of Digital Solutions for U.S. Water, a Kurita Co. “As society expands the use of artificial intelligence and machine learning into industrial business operations, many opportunities will develop to save time or money, increase production, identify and mitigate risks, or make operations safer.”

Industrial wastewater treatment systems typically control dosage according to a turbidity measurement at the sedimentation basin outlet. This results in a time delay of dosage control. S.sensing CS technology eliminates this drawback by measuring the clearwater phase between the flocs. This makes it possible to adjust dosages according to the inlet water quality. Too-high and too-low dosages are therefore avoided. Pumps are immediately adjusted to match the load of the inlet water. The result is a smooth process with stable water quality at an optimum product dosage and a reduction in sludge formation and its attendant costs.

According to the company, the S.sensing CS system supports efforts to proactively predict challenges, create more efficient water treatment specifications, achieve higher productivity and reduce environmental impact. That can make it a valuable tool in the effort to identify challenging water issues, ensure same-time optimum dosage, and promote a smooth and stable plant operation.

“As the integration of technology iterates, society will become more comfortable with its ability to make intelligent decisions,” Murdy says. “We each play a role in ensuring the technology is used responsibly — augmenting human intelligence, not replacing it.” 866-663-7632;
