Pulsafeeder powers clean water: From screening to chlorination, complete solutions for municipal wastewater treatment

Wastewater treatment benefits from Pulsafeeder.

John Brooks Company Limited supplies ample fluid-handling solutions for municipal water and wastewater applications, including options by Pulsafeeder. Although water is humanity’s most precious resource, only one per cent of the world’s water supply is usable as drinking water. Pulsafeeder prioritizes wastewater treatment as a principal area of its products’ applications.

Among the uses for which customers can count on wastewater solutions by Pulsafeeder are pH neutralizer or adjustment, flocculation, coagulation, chemical feed, antiscalant, and more.

Balancing efficiency with compliance

It is crucial to return pollution control of water to the environment – and to recycle industrial process water, the latter due to the availability and cost of fresh water. Municipalities and private corporations must handle water with utmost care, while balancing efficient operation with compliance with regulatory requirements. Pulsafeeder solutions from John Brooks Company help municipal water-treatment processes complete these important steps:

• Intake screening. Screens keep large debris from entering the treatment process and remove smaller items.
• Taste, odour control, and disinfection. Taste and odour issues are treated by metering pumps dosing potassium or sodium permanganate downstream from intake pumps.
• pH adjustment. Drinking water must have a neutral pH level of seven. pH adjustment is a constant balance; excessive hydrochloric acid needs extra soda ash later, for instance.
• Coagulant feed. Positively charged coagulant chemicals are used to bring tiny colloidal particles together to form flocs, or heavier aggregates, that become easier to filter.
• Flocculation and clarification. Metering pumps dose flocculation polymers into clarifiers to raise the settling rate for particles, after which sludge pumps remove materials to be dewatered and eliminated.
• Filtration and well storage. Water is filtered to remove remaining particles, then retained in clear wells long enough to enable enough contact time for disinfectants and to offer backwash water for filters.
• Fluoridation. Many municipal treatment plants add fluoride in their treatment processes.
• Post-chlorination. To prevent equipment corrosion, sodium hypochlorite is often injected.
• Distribution. Leveraging metering pumps at numerous stages makes drinking water available throughout the community.
• Chlorination. The process of adding chlorine to drinking water to kill germs and disinfect it.
