STEM Drive Ltd

About

Stem Drive Ltd manufactures and installs patented fluidic mixers for mixing and aerating liquids and slurries in the chemical, process, food manufacturing, and water and effluent treatment industries. · Submerged aerators / mixers The patented STEM Drive fluidic aerator / mixer is designed for systems requiring both aeration and mixing. Manufactured from stainless steel, the aerator / mixer is suitable for use with sludges and industrial effluent. As the system uses no moving parts within the media being aerated / mixed, and the power source is outside the tank, maintenance is kept to a minimum. · Sludge aeration Systems are suitable for aeration / mixing to control odours and eliminate stratification within sludge. Air or gas is used as the prime power source. The mixers are fully submersible, require practically no maintenance, and are suitable for use in arduous and hazardous environments. · Sitework Systems are easy to install, and can be fitted without emptying tanks, eliminating the need for plant shutdown. As no moving parts are used within the tank, maintenance can take place out-with the sludge, again minimising system downtime

800 Mixers sold to the Waste Water Industry

STEM Drive, leaders in Fluidic Mixing technology has recently achieved a land mark figure having installed 800 Fluidic Mixers throughout the UK Waste Water Industry.

This does not include the many and varied Fluidic Mixers used in the Hire Division, an ongoing 24 hour service offered to Industry in times of emergency and breakdown of other traditional mixing systems. In fact many permanent STEM Drive Fluidic Mixing systems have resulted following the use of a hire mixer, so impressed has the End User been of our system.

Over the past eight years a continued research and development programme at STEM Drive has produced a range of Fluidic Mixers to tackle a variety of demanding mixing regimes.

Not only does the Fluidic Mixer have the ability to bring a settled tank contents including its hardened crust to a homogenous blend within a very short operating period but the use of air as the motive power has a marked effect upon reducing odour levels.

In this context of developing the novel but simple principle of the Fluidic Mixer we are pleased to share with you some of the new arrivals onto our ever increasing range of mixers and ancillary equipment.

Firstly the arrival of the Mark III reverse inlet Fluidic Mixer incorporating an improved and refined nozzle jet arrangement. The field trials conducted on various grit laden sludges have proved in all cases to exceed the performance of the previous generation STEM Drive Fluidic Mixers.

This enhanced design not only improves the throughput of the 100mm Model but achieves this with a marked reduction in the quantity of compressed air required to drive the Fluidic Mixer.

In a typical Fluidic Mixing installation this will not only require a smaller sized compressor but the run time of the Mark III will be considerably shorter in a 24 hour period.

Hence, economies of both power consumption along with lower initial capital costs will be achieved with the improved and more energy efficient Mark III Fluidic Mixer.

To assist with the installation of our Fluidic Mixers within large, hazardous and confined space restricted tanks and to compliment our existing fixed and ski-slope installations a removable guide rail mixer is presently under consideration by a leading Water Company.

Following on from our use of the well proven CompAir Hydrovane compressor as the source of our Fluidic Mixers motive power we have in conjunction with CompAir produced a compressor set whose integral Control Panel fully complies with the stringent WIMES 3.04 standard.
Our Fluidic Mixers are being used in the following areas for many of the UK's leading Water and Waste Water companies:-

· Primary Sludge Mixing
· Secondary Sludge
· SAS Tanks
· Digested sludge
· Scum Tanks
· Inlet Works Storm Return Tank Mixing
· UID Detention Sump Mixers
· Detention Tank Mixing
· Lagoons
· Digesters
· Tank Emptying Umbilical Line
· Drains

Thus with our previous track record in the Water and Process Industries these additions keep STEM Drive Fluidic Mixers at the cutting edge of mixing technology with grit laden sludges to produce a homogeneous blend with no inherent blockages problems.
