Sump or Cooling Tower - Basin Sweeper System
A sweeper system using eductors can be used in conjunction with the Griswold Sand Filter Systems. Such sweepers systems are specifically engineered for each sump or basin and are designed to continuously circulate and direct the fluid stream toward the suction of the pump, preventing solids from settling to the bottom of the sump/basin. Model selection is based on the recirculation flow rate of the cooling tower and/or size of the cooling tower in tons.
sand filter + sand filter systemsGriswold Water Systems’ Sand Filters are designed as self contained units for your filtration needs. Models are compact, durable, and effective filtration packages.
Our sand filters come complete with their own pump, pipe manifolds, pressure gauges, basket strainer, a pump control panel and backwash controller.
how it works
technical details available on request
Fluid enters the upper body in a rotational direction, enabling the dirt/contaminants to continuously rotate with the water. This prevents the solids from blanketing the top of the media, keeping it fluidized at all times. Since many of the very light solids are kept in suspension in the top portion of the filter, the filtration cycle is longer, and the backwash cycle is shorter for more economical operation.
