CHEMSTREAM, INC.

Water Treatment Chemicals

Chemstream offers a range of specialized chemicals for water treatment applications in mines, quarries and municipalities. Chemstream will stay on the cutting edge of innovation and modern practicality by delivering the finest environmental products and product dispensing systems in the business.

Precipitation Chemicals (AMD Treatment)

This product adjusts the pH and oxidizes heavy metals causing precipitation and eventually, water clarification. This is the product of choice for treating acid mine drainage, as it rapidly precipitates and removes iron, manganese and aluminum. AMDTreat can be dispensed with the Wheel-Treater, Vario-Ject and many other liquid feeders.

Coagulation Chemicals

These products promote the formation of pinfloc which starts the water clarification process. They work exceptionally well on brown and gray clays when alkalinity is present in the water to be treated. They also remove suspended iron from acid mine drainage water and work over a wide pH range. These products can be fed with the Wheel-Treater, Vario-Ject and other peristaltic, diaphragm and piston pumps.

Flocculation Chemicals

This line of products rapidly clarifies water where there is a specific charge of the suspended particle. Individual flocculation products are used for specific pH and particle levels. These polymer flocculants are available in powders, emulsion liquids, solution liquids and jel-log formulations. They can be fed with the Wheel-Treater, Vario-Ject and other chemical feeders.

Potable Water Treatment Chemicals

These products are NSF approved for liquid chlorination, water conditioning and corrosion inhibition. They can be dispensed with any Chemstream pump or injector.

Dust Suppression Chemicals

These are concentrated surfactants for continuous underground dust suppression.

Other Chemicals

Chemstream provides chemicals for defoaming, descaling and other water treatment needs. 

Aeration Troughs and Pond Baffles

The Chemstream Aero-Troff trough provides exceptional aeration and mixing. It has a four-foot modular design and is easy to transport and assemble. It`s available in widths of 5``, 10``, 20`` and 40``.

The Aero-Troff modules are easily joined together with the ``rib connector`` on the leading and trailing edges. This allows for a modular design that can be customized for many different applications.

Aero-Edge Technology
 
Our unique Aero-Edge Technology provides three times the surface exposure for enhanced aeration. The aeration edges, which consist of two plates stacked on top of each other, are installed onto the slats of the Aero-Troff. These plates disperse the water, providing three times the surface exposure which greatly enhances aeration and mixing between the cells of the trough. This allows the chemical to be more thoroughly mixed with the water, which precipitates heavy metals prior to their theoretical precipitation pH point.

Pond Baffles

Chemstream Pond Partitions allow treated water to be retained longer in treatment ponds, thereby eliminating the problem of water ``short circuiting`` from entrance to exit of pond.

Chemstream Pond Partitions have a sturdy construction built to withstand the elements:

• No stitching, only durable heated bonding
• Tough UV inhibited poly-fabric for 15+ years of use
• Custom sized polystyrene floats
• Partition ends reinforced with brass grommets

Water and Electric Powered Chemical Metering Pumps

Wheel Treater

There are a lot of chemical metering pumps that you can easily plug into a 110-volt socket. But what if you don`t have electricity and solar power is not practical? Furthermore, without on-the-spot labor, who is going to switch an electrical pump on and off and adjust the feed rate?

Enter the Wheel-Treater, a device that`s entirely powered by the flow of water, usually a small portion of the total flow.

In addition to being completely water powered, the Wheel-Treater is also responsive to changing water flows. This means that when the water stops flowing, the treatment stops. The chemical feed rate will follow varying water flow rates thereby increasing accuracy, eliminating waste and lowering treatment and labor costs.

Waterwheels have been used for thousands of years, but new runner and cup designs have evolved. Since the Wheel-Treater is designed to operate at relatively slow speeds, the runner design is simple and low maintenance. Since its original design, the Wheel-Treater has evolved to maximize torque, foot-pounds of power and hydraulic efficiency. Additionally, all models have large carrying handles and can be moved without heavy machinery.

Drive Assembly Options
 
C-Drive. The chain drive setup provides mechanical advantage by increasing pump speed as compared to wheel speed. The HS-2 and HS-3 models propel the pump at a higher speed than the wheel. The slots on the long shelf accommodate the 500 and the 610 Randolph-Austin peristaltic pump. The chain drive can also be adapted to drive a small 100-PSI peristaltic pump.

D-Drive. With a short shelf, the Wheel-Treater can be adapted to direct drive the 250, 400, 500, and 610 Randolph-Austin peristaltic pump. This is the simplest and most maintenance free setup. The rate of chemical injection is controlled by wheel speed and tubing diameter.

Z-Drive. The long shelf can also accommodate the Z-Drive, which adds an adjustable Zero-Max gearbox for pump speed control independent of the wheel speed. Comparatively, the typical Z-Drive has about 1/10 the chemical output of the D-Drive model. With a reverse sprocket ratio, the Z-Drive output can be doubled. The strong point of the Z-Drive is adjustability.

Increase the control of the Wheel-Treater by adding one of the following optional accessories:

• Zero-Max Gearbox
• PVC 3-way valve
• Cat`s Eye Tachometer

Each additional accessory increases the control of the chemical pump speed, thereby further controlling the chemical metering rate. Any combination of these accessories can be added to the Wheel-Treater.

The Wheel-Treater is predominantly comprised of stainless steel. The peristaltic pump housing is aluminum with a stainless steel option. The safety fenders are ABS plastic. Water can be gravity fed or pump fed into the intake port. Typically only 2-10% of the total flow rate is channeled into the Wheel-Treater. The distributor manifold sends water to the wheel at an 11 o`clock position on the runner. The water then drains from the runner at a 6 o`clock position.
 
The Randolph-Austin peristaltic pump has stainless steel sealed bearings. The pump mounting stage will accommodate two smaller pump sizes and the option of a Zero-Max gearbox drive. Various tubing adapters are included with every unit, making connections fast and easy. The peristaltic pump will accommodate two tubing sizes.
 
The Wheel-Treater has large lifting handles on both sides for portability. The runner outflow is completely contained with a 6`` NPT drain outlet.

Electric Chemical Pumps

The Vario-Ject line of chemical pumps is rugged and dependable and can inject high viscosity liquid chemicals up to 100 PSI. There are two types of Vario-Ject pumps: the Vario-Ject GearPump and the Vario-Ject PeriPump. Both are 90-volt DC-converted speed-controlled.

Vario-Ject GearPump

The Vario-Ject GearPump uses a Teel brass gear pump that can pump against a pressure of 100 PSI.

Vario-Ject PeriPump
 
The Vario-Ject PeriPump uses a Randolph-Austin peristaltic pump that can pump against a pressure up to 25 PSI.

The Chemstream Vario-Ject PeriPump system consists of a variable speed DC gear motor coupled to a Randolph-Austin peristaltic pump. This provides finely tuned control over chemical feed with no possibility for siphoning or waste. The only thing that comes in contact with the chemical is the inside of the tubing. AMDTreat 252 is injected in the treatment building followed by the injection of EverFloc 200W at the head of the Aero-Troff. Both products are designed for outside storage throughout the year.

In addition to the Wheel-Treater and Vario-Ject lines of pumps, Chemstream can also supply pumps from the following companies:

• Peristaltic Pumps
• Blue-White Industries Flex Flow Pump
• Stenner Pump
• Electric Pumps
• Pulsafeeder Pump
• LMI Pumps
• Piston Pumps
• A & F Piston Pumps
