Inyo Process’ line of porous metal seamless injectors create bubbles smaller and more numerous than a drilled pipe or other types of spargers. With greater gas/liquid contact area, the time and volume required to dissolve gas into liquid is reduced.
The most important factor when injecting gas into liquid is to increase the surface area of the gas to ensure fast absorption into the liquid. This is accomplished by reducing the bubble size, which creates many slow moving, tiny bubbles that result in a large increase in absorption.
The advantage of the Inyo Process injectors is the tight and consistent pore structure to all of our stainless steel gas injectors. This consistent pore structure provides a high bubble point which results in tiny, consistent bubbles.
All stainless construction lasts for years. The durable all –welded construction will remain trouble free for many years. Often the porous injectors can be easily cleaned using a ultrasonic bath.

Pipeline Spargers
Installing a porous injector in a pipe will always result in greatly reduced bubble size. The gas will exit from the outside of the porous injector, and the bubbles are immediately sheared by the liquid, resulting in very tiny bubbles and greater absorption.

Injectors can be mounted across the pipe diameter
External Spargers
We can also supply a complete line of external spargers, which use high-shear tangential forces to produce a stream of micro-bubbles.

Injection Wafer
Designed to be sandwiched between flanges, the Injection Wafer provides a simple means of adding injector ports to a piping system. The wafer injector can accept threaded injection quills and retractable injectors
Advantages
Allows for inserting injectors without damaging interior finishes/coatings or linings of piping.Multiple injector port design allows for adding non-compatible chemicals by injecting at different positions in the pipeline.Ability to install both threaded injection quills and removable corporation stop style injectors that can be removed while the system is under pressure.Improve existing injection systems by using multiple injection points
Ease of Use
Easy installation of injectors into an existing piping without welding.
Available with injection quills in all materialsAvailable with Flanged ports.We can provide wafer injectors that will fit in all domestic and foreign flanges including:ANSI/ASME B16.5 125# & 150# flanges, AWWA C-207, DIN, British Standard and Australian Standard

Custom Injection Wafers
Inyo can offer a customized wafer to meet the requirements of your application. Below are some examples of custom injection wafers
This all CPVC injection wafer uses a series of Hastelloy spring/ceramic ball check valve injectors and injection wings to allow for even dispersion of the injected chemicals. A number of chemicals were added to a produced water treatment facility in an oilfield.
This ring style stainless injection wafer uses nipples to ensure that the connections are readily accessible from outside of the flange perimeter
Used for injecting dilute polymer into a belt press dewatering sludge application.
These full diameter PVC injection wafers include integrated injectors
Polymer Injection into Sludge for Dewatering
Inyo Process has a range of solutions for dispersion of dilute polymer into a sludge or slurry including:
- Sludge Injection Disk
-
Sludge Injection Spools for Mining Tailings (at bottom of page)
Sludge Injection Disk
(Shown) Sludge Wafer Disk sandwiched between flanges (injection port not shown)
Designed to specifically for mixing polymer to sludge applications before dewatering, this wafer injector distributes polymer evenly throughout the sludge. Sludge Wafer is designed to fit between 125# or 150# flanges.
Typical sludge wafer disk (10" dia.disk shown) designed to provide even distribution of polymer. Shown with optional manifold assembly
Advantages
Provides excellent mixing for sludge/ polymer mixing. Polymer is injected deeper into the sludge stream for better mixing.
Non-plugging, single opening design with no place for fibers or small debris to hang up in wafer.
Able to pass debris up to 3/4 the size of the pipe diameter.
Multiple Injectors-The 4 injector ports are position to inject polymer evenly throughout the sludge.
No Fouling--No place for sludge to hang-up as it pass this injection wafer.
Easy installation-Sludge Injector Wafer is sandwiched between flanges.
Easy inspection-Simple to remove the wafer by removing the bolted connection
Ease of Use-Fits into an existing piping without welding.
We can provide wafer injectors that will fit in all domestic and foreign flanges including:ANSI/ASME B16.5 125# & 150# flanges, AWWA C-207, DIN, British Standard, and Australian Standard.

Inyo can provide alternate styles of injection wafers designed for polymer injection into sludge. Integrated tapered injectors allow for even dispersion of polymer and enhance turbulence in sludge to ensure full distribution of polymer through the (4) ports. Non-fouling design. Full flange design including bolt holes.

Polymer Injection System for Mature Fine Tailings (MFT)
Oil Sands mining creates many unique problems for polymer injection. The amount of sludge that needs to be treated dwarfs any other sludge/slurry application. When injecting polymer, even minor improvements in the efficiency of the use of the polymer can create large cost savings for the end user by reducing polymer consumption.
The Inyo MFT sludge injection system is designed for the unique challenges of this market.
The Inyo MFT system includes a specially designed non-fouling static mixer suitable for this type of non-newtonian sludge and an injection ring that injects deep into the sludge stream. Contact us for more information.
