WesTech has built a solid reputation for reliable process equipment and superior service worldwide. We design, engineer, and manufacture quality equipment for municipal, mining, and industrial treatment applications.
Process Equipment. Process Driven.Since 1973, WesTech has gained extensive experience
in water and wastewater treatment for a wide range of
equipment and processes. Prior to making a treatment
recommendation for a particular application, WesTech
works closely with you to gather necessary information
for the entire process. This process driven approach,
along with the combined experience of our process and
application engineers, ensures a successful facility that
accomplishes your essential treatment goals.

Biological Flow Sheets A well designed wastewater plant starts with your effluent
requirements and an energy efficient biological process.
WesTech has multiple biological process options to
match your application and preference. From trickling
filters to oxidation ditches, WesTech’s biological process
equipment will give you the effluent quality you need and
the foundation for a successful wastewater plant.

CleanFlo™ SHEAR Our direct-drive drum screen eliminates chain and bearing maintenance. Get high solids removal for your conventional screening or pre-membrane application.
Landox ProcessSeparate your aeration and mixing in an oxidation ditch to conserve energy and promote biological nutrient removal with WesTech’s Landox.
Dual-Gate™ EDIProduce well-flocculated solids that spread gently and evenly into the clarifier without disturbing the settled sludge blanket on the basin floor.
WesTech wastewater equipment includes a variety of choices to complete your plant design or improve the performance of your existing system.
Membrane Bioreactor Systems WesTech supplies a complete biological s ystem for your
MBR plant. The ClearLogic™ MBR combines the benefits
of flat sheet and hollow fiber technologies into our hollow
sheet membrane. For a low maintenance, energy efficient,
high performance system, integrate our STM-Aerotor™ or
OxyStream™ for pre-aeration to the membrane tank.

Complete Headworks SystemsBefore recommending one of our headworks systems,
WesTech takes the time to evaluate the collection system,
site conditions, biological process, solids disposal
restrictions, and owner preference. Whether you operate
a lagoon or a membrane plant, WesTech can provide the
correct screening and grit removal equipment to improve
and protect your downstream plant operations.

Clarification CapabilitiesWesTech leads the way in clarifier design through
our field testing and ongoing research of sedimentation
equipment. Giving the industry the COP™ Clarifier
Optimization Package, WesTech has become
synonymous with spiral blade clarifiers. WesTech also
provides suction header type clarifiers and custom built
units to meet your plant requirements.

Anaerobic Digestion OptionsRecover valuable energy with WesTech’s anaerobic
digestion process equipment. We offer complete digestion
systems to store solids, provide mixing, capture methane
gas, and convert it into usable energy.
Along with our rugged Extreme Duty™ Sludge Mixer and
Steel Digestion Covers, WesTech offers the DuoSphere™
Dual Membrane gas holder for installations on tanks or
concrete slabs. The dual membranes drastically decrease
installation costs by eliminating the steel components, field
welding, and field coating.
Sludge RingSludge blankets will be lower and solids concentration will be higher with the sludge withdrawal ring. WesTech’s sludge ring can upgrade your suction or hopper clarifier.
Slide GuidesWesTech’s slide guides prevent tipping and binding of floating and gasholder covers as they move vertically in the tanks.
Tertiary TreatmentFrom continuous backwash sand filters to ultrafiltration membranes, WesTech can help you achieve reuse of quality effluent.
