The Key Differences Between By-Pass Feeders and Filter Feeders

by PSG | Mar 16, 2023

For decades, Neptune® has provided superior technology engineered for the water and wastewater industry. Neptune is the only manufacturer that offers a comprehensive portfolio of end-to-end technology, including By-Pass Feeders and Filter Feeders, designed to improve system efficiencies and help ensure optimal operation for water and wastewater applications. 

While Neptune By-Pass Feeders and Filter Feeders both deliver the peace-of-mind reliability needed in water and wastewater applications, some differences must be considered when selecting the right technology for your specific operation.

Neptune By-Pass Feeders

Neptune By-Pass Feeders provide a convenient method of introducing treatment chemicals into hot and chilled water closed-loop recirculation systems, such as heating air cooling systems, process heating and cooling, or large engine water jackets – all while protecting the internal metal from corrosion.

Features

  • Neptune offers two styles of By-Pass Feeders: The vertical style with dish bottom out (DBF Series) and the vertical style with dish bottom in (VTF Series).
  • The DBF Series features demountable leg extensions, a full bottom drain and an optional filter bag kit. 
  • The VTF Series is the most popular and economical style, featuring a full bottom drain and optional filter bag kits. However, this series comes without the demountable leg extensions. 
  • All By-Pass Feeders feature a quick-opening, high-pressure cap designed for better sealing with less required force and no need for tools.

Neptune Filter Feeder

Neptune Filter Feeders operate similarly to By-Pass Feeders but with the added capability of high-capacity filtering all in one piece of equipment.

Features

  • Eliminate the need for a separate By-Pass Feeder and filter.
  • Filtration can be achieved at the same time as chemical addition.
  • The extended neck with top inlet allows simple installation of filter bag and basket.
  • Filter bags are simple to replace and are available in 50-, 20-, 5- and 1-micron ratings (order separately).

Neptune By-Pass Feeders and Filter Feeders provide the efficiency, reliability and safety needed in water and wastewater applications. However, depending on your application requirements, one technology may be more ideal.
