The Micro-Screen Separator is an ideal machine for removing suspended solids and debris from effluent water streams. Taking our standard “Sidehill” Separators a step further in the removal of solids.
With its efficient design and high flow rate, our Model 500 can process up to 30,000 gal/hr depending on mesh size and influent. Mesh sizes down to 400 (37 micron) can be used to maximize water cleanup and solids removal, helping discharged effluent to reduce BOD and TSS levels saving the environment and cost.
Our Micro-screen machines use our patented wash system to clean and prolong the life of the screens reducing maintenance, time and cost. These machines are also available with a complete CIP (clean in process) system to potentially eliminate the need to add fresh water to the self-cleaning process.
In addition to our standard Micro-Screen units, we also offer two stage machines which use a perforated stainless steel secondary screen to prescreen the influent extending the life and wear of the finer mesh screens. This also offers another layer of solids reduction.
Key Dollar Separators come in many sizes and configurations that can be tailored to your needs. Our Micro-screen machines are available in 100, 250 and 500 gal/min models, in a single stage or with two stages. Micro-screen Separators are also available with fully automated controls to further fine tune to your separation and dewatering needs.
At the 1986 World Ag Expo in Tulare, our Micro-Screen Separator was voted “The best separator for producing the cleanest water for lagoons."

“We want to thank you for this machine. It is a “Deusie”. What is important is the fact that this machine has been basically trouble free since we received it. It has been used 360 days per year for years and we have run in excess of forty million gallons of septage through it with very few problems.”

“My wastewater is pumped with a 7.5 hp centrifugal water pump through a big gun with 4″ PVC. It is pumped over a mile. This is only possible because there are no solids in the water, thanks to Key Dollar Separator.”

Neil Michael, Plant Engineer at National Frozen Foods in Albany, Oregon
“In order to keep the Department of Environmental Quality satisfied after citizen complaints of the odor from the lagoon, lime treatment had to be applied until the odor was under control. Three years ago they put in two Key Dollar Micro-Screens and have not used lime since and have NO BAD ODOR SMELL! All their cannery water is pumped three miles out of town.
The Key Dollar machines operate using water it cleaned to clean its own screens – NO OTHER WATER NEEDED! They operate automatically. They turn on when the water comes on and turn off when the pump stops. The solids removed are spread on fields nearby and are not allowed to spoil. They can be spread on pasture, new cut hay or on ground to be cultivated. Neil Michael said he would be pleased to talk to anyone who had or has lagoon odor/smell problems.”
