  1. Almost all of ISI’s cylindrical screens are designed and installed to be easily retrievable. ISI recommends that screens be retrieved during high flow events or when not in use for long periods of time if possible.
  2. ISI screens use durable wedgewire construction and are capable of withstanding severe conditions without damage. We will design a screen system to meet the site needs.
  3. Cone screens can be left in place in most applications. By design, they are typically sited on the river bottom and are not subject to the higher currents and floating debris. Its cone shape also helps to deflect debris without damage.
