Plant Influent

Wastewater or other liquid, raw or partially treated, flowing into a treatment plant.

Raw Wastewater Screens or Comminutors

Raw Wastewater Screens are a pre-treatment process to remove large suspended or floating solids from raw sewage to prevent subsequent plugging of pipes or damage to pumps.
Comminutors are a shredding or grinding device that reduces the size of gross suspended materials in wastewater without removing them from the liquid.

The Main Wastewater Pumps

These pumps are the first to see wastewater, therefore they are designed to meet rugged standards, Since the pumps must deliver a wide range of flows, Centrifugal pumps are usually the accepted choice because of their smooth channels and impellers with large sized openings to prevent clogging. However, ACCA pumps are being used on high head lift stations to wastewater plants. A Progressive Cavity Pump can be used at this point to sample the raw wastewater.

Grit Chamber

There are several types of grit chambers from which to choose. Some are aerated and others depend on proportional weirs or other devices to regulate velocity and grit separation. The grit chambers are designed to remove inorganic materials that could cause excessive equipment wear or interfere with the operation of other plant equipment. Examples of grit would be sand, coffee grounds, and cigarette filter tips. Aerated grit chambers provide a period of wastewater detention for the purpose of trapping grit through the use of an air-induced rotation of the wastewater. Compressed air, usually from the plant’s process air supply, is used. Cyclone Grit Removal is a process whereby a centrifugal force is used to separate grit from organics in a cone-shaped unit. A recessed impeller pump discharges a slurry of grit and organic matter tangentially (high velocities of fluid entering the cyclone) near the upper end of the degritter at the perimeter. This discharge creates a vortex that produces a grit slurry at the lower, narrower opening, and a larger volume containing volatile material at the upper port, The grit flows out the bottom and the degritted flow enters the plant to receive further treatment.

Two other grit chambers used are hand-cleaned chambers and mechanically cleaned chambers. The important thing to remember is if grit is not removed early in the treatment process, inevitably it will cause problems later.

Primary Sedimentation and Grease Skimming Tanks

The purpose of primary sedimentation is to separate the settleable and floatable solids from the wastewater for appro­priate handling. Primary settling tanks remove the larger sized solids from wastewater before it is discharged to receiving water or secondary treatment units. Solids that readily settle are collected from the bottom of tanks as primary sludge. Floating materials such as grease and oils are skimmed from the top of tanks and removed as primary scum. ACCA pumps can be used for three different applications during this process, the primary sludge removal to the digester, the primary scum removal, and the primary wastewater to the aeration tanks.

The advantages of a Progressive Cavity Pump would be:

• High Solids Handling Ability.
• Reversibility – easy unclogging of most plugged suction lines, thereby cleaning scum and grease that normally clings to the I.D. of the pipelines.
• Metered Flows.
• High Head Capabilities.
• Open Throat Suction Ports available for hig
• solids content and thickened grease.
• Cleanliness and Elimination of Odor.
• No Valves — ACCA PCP is a valveless pump with no clogging problems.
• Non-Pulsating Discharge Flow.
• Quiet Operation — Less than that required by government standards.

The Progressing Cavity (PC) Pump excellent for handling abrasive sludges, slurries, and metering applications at Waste Water Treatment Plants. It also offers the following additional Benefits:

1. Ability to handle thick fluids (Polymer in excess of 1,000,000 centipoise/70 solids cake from plate and frame filterpress)
2. Ability to meter accurately (controlled flow rate for feeding dewatering equipment)
3. Ability to handle solids without damage (will not harm floc)
4. Ability to handle shear-sensitive fluids without agitation (will not damage polymer)
5. Suction lifting and self-priming (can suction lift H20 up to 28 feet)
6. Ability to maintain constant flow rate with wide variations in suction and discharge head conditions (flow rate will be the same whether tank is at high level or low level or regardless of sludge being thick or thin)
7. Non-pulsating flow
8. Energy-efficient
9. Low noise level
10. Maintenance and repair capable of being done on-site by the treatment plant’s staff

Sludge Pumps for Waste Water Treatment Plants

First, consider the abrasive characteristics of the sludge. For purposes of selecting progressing cavity pumps, most municipal sludges are considered to be of medium abrasion. Some municipal sludges are considered to be of heavy abrasion. The following are common causes of sludge of heavy abrasion:

• combined storm and sanitary sewers
• ineffective or no grit system
• rocks
• snails
• trash (tramp metal, bottle caps, sticks, wire, glass, etc.)

Progressing cavity pump selection is different for sludge of medium abrasion than it is for sludge of heavy abrasion:

General Specifications for Sludge

specify crown gear-type universal joints

specify inspection ports/clean-our ports/handholes

specify hollow shaft

if sludge has more then 10 percent solids, specify open throat, hopper-type suction port

specify pressure relief system (pressure sensor/switch, rupture disc. pressure relief valve) on discharge side of pump

if there is a chance that the pump could accidentally run dry, specify a flow detection device on suction side of pump

Special Condition Pumping Sludge with a PC Pump

high rag/hair/stringy material content

• consider sludge grinding
• if there is no sludge grinding, specify protective cover on universal joint-shaft
  area

NOTE: Inspection ports/clean-out parts/handholes and hollow shaft are strongly recommended when sludge has high content of rags, hair, or stringy material.

high rock or trash (tramp metal, bottle caps, sticks, wire, glass, etc.) content

• consider sludge grinding
• specify a trap (inverted tee) in the suction line

Suction lifting/long suction lines/negative suction conditions

• If packing is used as the sealing device and the discharge pressure is less than 50 psi, specify the pump to operate in reverse rotation (this puts the stuffing box on the pressure side of the pump, eliminating the possibility of pulling air through the packing), or utilize a mechanical seal as the sealing device or specify a water seal system for the packing (this is not as fail-safe as reverse rotation)

Pump/grinder combinations

Wafer and lug valves are two common types of butterfly valves used in various industries. The main difference between them lies in how they are mounted. Wafer valves are sandwiched between pipe flanges using bolts, while lug valves have threaded inserts on the valve body for bolt attachment. Wafer valves are lighter and more compact, making them easier to install and remove. Lug valves are more secure and can be used in systems where one side of the piping can be removed without affecting the other side. Understanding the differences between wafer and lug valves is essential for selecting the right valve for specific system requirements.

Why Aftermarket Pump Parts are beneficial to the industry? 

Aftermarket Pump parts are a necessity to the Fluid Handling Industry. There are many changes that can happen to an Original Equipment Manufacturer of Pump Parts and determined the outcome of a product line. Sometimes OE Manufacturers are bought out and consolidate or outdate their product lines, and end users are left with an investment that is unserved with no other choice than to do a large capital investment to upgrade perfectly working pump applications. Other times, the Original Manufacturer Equipment as a sole source of the product abuses on the price they sale replacement pump parts and pumps. As we have seem a few times through out the years, Original Equipment manufacturers can go through a policy conflict within the company and simply stop production for a period of time, and we have also seen how supply chains are interrupted leaving the ends users with a delivery time that is unacceptable from the Original Equipment Manufacturer. Therefore, A well developed alternative supplier for complete pumps and pump parts is a necessity to the a healthy Fluid Handling Industry.

Original Equipment Manufacturer Pump Parts vs Aftermarket Pump Parts – Which one is right for you?

Most Original Equipment Manufacturers Such as Moyno® and Netzsch® for progressing cavity pumps and Flowserve® and Goulds® for centrifugal pumps will promote than their parts will perform better than aftermarket manufacturers. The case is that in today’s manufacturing world of CNC, 3d Scanners and printers, and new technology, aftermarket non-original manufacturing has caught up to any Original Equipment manufacturers and in some cases advance in technology and quality when compare to the OEM’s product.

Globe valves and gate valves are two common types of valves used in various industries. The main difference between them lies in their design and function. Globe valves have a globe-shaped body and a plug or disc that moves up and down to regulate flow. They are ideal for throttling or controlling flow rates. On the other hand, gate valves have a gate-shaped closure element that moves perpendicular to the flow of the fluid. Gate valves are typically used for on/off applications where the fluid flow is either fully open or fully closed. Understanding the differences between globe valves and gate valves is essential for selecting the right valve for specific system requirements.
