LACKEBY Roto-Sieve® drum screen is an internally fed, self-cleaning, inclined drum screen that can be used in many industrial and wastewater treatment applications where high-efficient particle separation is needed. Lackeby Products AB is represented in Southern Africa by Monitor Pumps & Systems.
A Swedish company specialising in waste disposal was in search of a solution to separate plastics and metal particles from the oil collected from oil separators, before pumping it to the oil tank for storage prior to further transportation and recycling.
Lackeby’s Roto-Sieve® RSS24 septic unit was deployed to filter the floating oil. The drum screen, equipped with a 3.0mm hole perforated drum, proved highly effective in screening the impurities from the oil.
When high performance, simplicity and low costs are the priorities
Lackeby Roto-Sieve® drum screen, with its self-cleaning design, performs excellently in many different applications and ensures low maintenance costs. Industrial applications include food and beverage processing, plastic and metal recycling, fibreglass, and biogas sludge screening.
In the water and wastewater industries, applications include primary, fine, septic and sludge screening as well as sludge thickening, reject water screening and MBR (membrane bioreactor) protection.
The Lackeby Roto-Sieve® drum screen achieves a high degree of separation due to perforated drum and pressureless separation. There is no need for upstream screening before the drum screen and there are no sealed openings or internal moving parts that can result in material passing through. The entire flow must pass through perforated holes to reach the downstream process. These features result in high capacity and a high capture rate with a small footprint.
Monitor Pumps & Systems provides cost-effective and low-maintenance solutions
The lifetime of a drum screen is normally more than 20 years and the self-cleaning design ensures a low degree of maintenance. Few moving wear parts are accessible without cranes or any other lifting devices. The drum screen is also low on energy consumption and the low spray-water consumption assures substantial savings in water costs.
The Lackeby Roto-Sieve® drum screen has a low number of moving parts. The advanced carbon fibre polychain drive system eliminates the need for trunnion wheels. This significantly lowers required maintenance and improves reliability. No chains of any kind results in less maintenance issues and there is no need for automatic oilers. Lightweight fibreglass covers ensure easy access for full visual inspection.
With more than 5500 installations in various types of industries and wastewater treatment plants worldwide, where separation of solids from the process water is essential, the Lackeby Roto-Sieve® Drum screen has proven to be versatile and highly efficient.
