A Brief History Wastewater Treatment In The USA

Despite water’s natural ability to cleanse itself over time, the ever-growing U.S. population has become so concentrated that high-quality treatment is imperative. In the 19th century, outbreaks of life-threatening diseases were traced to bacteria in polluted water. Since that time, the practice of wastewater collection and treatment has been developed and perfected, using some of the most technically sound biological, physical, chemical, and mechanical techniques available.

1800s – Awareness & Response U.S. population grew from 5 million to 75 million Pit privies and open ditches were replaced by buried sewers The sewered population jumps from 1 million in 1860 to 25 million by 1900 Simple treatment begins (now called “primary” treatment) 1886 – Standards for discharge loading and treatment were developed at a Lawrence, Mass., experiment station 1887 – First biological treatment, an intermittent sand filter, was installed in Medford, Mass. 1899 – First federal regulation of sewage: Rivers and Harbors Appropriations (“Refuse Act”)

1900s – Technology & Regulation Early 1900s, 1 million people served by 60 “Solids Removal” treatment plants 1901 – First trickling filter operated in Madison, Wis. 1909 – First Imhoff tank for solids settling 1914 – First liquid chlorination process for effluent disinfection 1916 – First activated sludge plant was built in San Marcos, Texas 1944 – Streeter Phelps created the DO (dissolved oxygen) sag curve model to predict assimilation capacity 1948 – Federal Water Pollution Control Act, leading to water quality surveys and swift construction of treatment plants Sketch of Wall, Broad and Nassau Street sewer system, N.Y. 1885 1960 – 50% of U.S. population had access to some form of wastewater treatment 1966, 1977 – Clean Water Restoration Act and Clean Water Act extended federal grants for plant construction

Constructing Milwaukee’s sewer system in the 1920s Defining Wastewater Wastewater Treatment

Wastewater treatment refers to the physical, chemical, 21st Century Concerns and biological processes used to remove pollutants from Aging Infrastructure wastewater before discharging it into a body of water. Since the Clean Water Act issued in 1972, there are now Management of Capital Expenses more than 16,000 publicly owned wastewater treatment Managing Operational Costs plants (POWTs) in operation in the United States. Funding/Availability of Capital Increasing/Expanding Regulations Approximately 255,000 million gallons per day (mgd) Technology Changes of industrial wastewater—treated by chemical, physical, Treatment Technologies and biological processes—are discharged daily into U.S. Aging Workforce waterways. Industries commonly reuse wastewater and Water Scarcity process water as its availability becomes scarce. Source: Water Environment Federation (www.wef.org) Water Loss Source: Black & Veatch

The Clean Water Act (CWA) is the primary federal law in the U.S. governing water pollution. Its objective is to restore and maintain the chemical, physical, and biological integrity of the nation’s waters by preventing pollution, providing assistance to publicly owned wastewater treatment plants (POWTs) for the improve- ment of wastewater treatment, and maintaining the integrity of wetlands. It is one of the country’s first and most influential modern environmental laws. As with several other major U.S. federal environmental statutes, it is administered by the U.S. Environmental Protection Agency (EPA) in coordination with state governments.

Pumps n Valves n Service Wastewater 101 What happens in a wastewater treatment plant is essentially the same as what occurs naturally in a lake or stream. The function of a wastewater treatment plant is to speed the process by which water cleanses (purifies) itself. A treatment plant uses a series of treatment stages (primary and secondary) to clean the water so that it may be safely released into a lake, river, or stream.

The Wastewater Treatment Process Primary treatment removes about 60% of suspended solids from wastewater. This treatment also involves aerating (stirring up) the wastewater to replace lost oxygen. Secondary treatment removes more than 90% of suspended solids.

Solids Separation To prevent clogging, it is critical that solids contained in raw sewage and stormwater be removed early in the process. Modern plants typically begin this process at the Headworks, where raw sewage collection takes place. Pumps at collection stations are subject to some of the toughest duty. This is where many clogs can occur if equipment is not matched to the conditions. Some plants use grinder mechanisms upstream of the pump to help reduce the size of debris. Still, stringy, fibrous materials easily pass grinders and can create havoc within the pump and filtration systems resulting in clogs and ragging.

Pumps n Valves n Service Ragging & Clogging A Systemic Problem Conquering The Clog: A Systems Approach Worldwide wastewater pumping stations that worked well in years past are now struggling because of new sewage handling challenges. The composition of today’s sewage is different due to an important trend: the prevalence of supposedly “flushable” wipes. Plastic bags, hygienic articles and, in extreme cases, even car tires are found in sewer systems that were not designed to handle the extended load these items place on the system.

At the same time, the global pump industry is moving steadily toward a sustainable environment requiring low energy consumption and high efficiency for machines and processes.

Sedimentation tanks allow the heavy sludge to settle to the bottom and be pumped out. Dewatering allows thickening of the sludge prior to processing in large digester tanks. Cutting vs. “Clean Transfer” Transfer Fluid Materials ... Not Problems

Some pump technologies have designed impellers to cut up the waste and move the smaller pieces downstream, simply transferring the problem. KSB handles the wastewater load without the energy-sucking chopping process.

The quality of the world’s sewage systems has been influenced in the past few years by four main factors:

1. Design of the system of pipes and valves 2. Design of the pump sump FAC T: The vast majority of operator 3. Pump operating configuration call outs to pumping stations are a 4. The pump itself—including impeller type and design direct result of pump blockage.

Side Effects of Cutter or Grinder Pumps The “Garbage Disposal” in Large Collection Systems method is old technology The fouling process is more likely to begin in the pipework. “The Garbage Disposal method is becoming a thing If raw sewage is ground or chopped in the early stages, the loads will consist of small parts and the total surface area of the past. I’m tired of will be much larger than before. unclogging pumps that are supposed to cut and grind.” Fouling before treatment may greatly increase odor in the pipes and pumping stations. Operations Manager, Waste Treatment Plant, CA Smaller substances are more likely to pass through screens.

The specific weight of the materials is not high enough for them to settle down later in the precipitation tank.

Any cutting, chopping, or shearing process requires additional energy. Especially in pump models with retractable impellers, the reduction in efficiency is up to 25%.

Extending the clearance to pass the loads will impair the impeller blades’ efficiency.

Chopper pumps require additional motor energy reserves.

In operation, the shear process creates friction, wearing down the impeller. The additional energy travels from the edge of the blades and attacks the hydraulics.

4 Keys To Successful Wastewater Treatment Processing

1. PUMP STATION DESIGN

While the increasing use of wipes is a challenge, different systems will handle this problem differently, and variable fluid content will influence performance. Engineering and planning of wastewater facilities requires knowing what kind of wastewater or sewage must be pumped for trouble-free performance and energy efficiency.

There are three general types of wastewater pumping stations, depending on pump types used:

1. Conventional Dry Pit Pumping Stations

KSB Know-How: This helpful booklet from KSB will 2. Submersible Pumping Stations help ensure proper design for an efficient system. 3. Submersible Pumping Stations In Dry Pit Installation

2. AUTOMATION

KSB offers a highly specialized variety of technologies to assist in the control and monitoring of the wastewater treatment process. This can include Process Control Systems to monitor and optimize pumps, valves, flow rates, and other critical information.

VFDs For Sewage Transport

Just 20 years ago, many professionals did not consider using KRT designed in a Dry Pit variable frequency drives (VFDs) in wastewater applications. Frequency converters were relatively expensive and experience using them with the special conditions and requirements in wastewater was limited.

Today, VFDs are often used in sewage transport. With correct usage and detailed knowledge, VFDs can support trouble-free operation. However they also can disturb proper functioning of a well-designed pumping station.

Because of the increase in wipe usage and the new challenges in sewage, it is even more important to consider the right exertion. Since 2010, there have been reports on the usage of VFDs and backward operation as a de-ragging method. In some cases it makes sense to use these tools, but they have some limitations Sewatec with KSB VFD system that engineers must be aware of. 3. SOLIDS SEPARATION

In all waste streams there are both solid and liquid components. To conquer the clog, the first step in the treatment process is to remove as much of the solid components as possible. This is done somewhat in sequence: A typical screen loaded with wipes and debris 1. Headworks: Screens remove the largest debris. Pumps working at these pumping stations have the toughest duty and exposure to wear and pump malfunction. 2. Grit removal, filtering basins, and sedimentation basins continue the process as liquid goes further into the treatment process. 3. Ultimately, the solids are either screened early and taken to landfills, or they are processed as sludge and treated in large digesters, where they are rendered as fertilizer or sent to a landfill. AmaDS3 Solids Separation Package from KSB

4. HYDRAULICS

Conquering the clog requires a systemic approach. This holistic perspective dictates that all parts of the treatment plant system are designed for flexibility in ever-changing conditions.

Constant changes in the volume and density of wastewater require systems that are versatile. twenty-first century wastewater realities have impacted system designs: from the headworks, through the pipes and tanks, all the way to the Digesters.

How To Challenge the Spec

Some manufacturers use steel or chrome for their impellers and other components. However, cast iron is less expensive and more durable. It you are not cutting the solids, you do not need the sharper edge that steel or chrome provides.

Pumps that work properly do not need these expensive materials to perform their primary task—moving fluid. KSB moves the solids without the extra step of cutting, chopping, or grinding.

Myth vs. Reality Myth Reality KSB Advantage

KSB pumps handle large solids so that the pump doesn’t clog. Competitor claims about energy efficiency comparison Eliminating the need for cutting makes the vortex impeller tests are performed in clean water, a common industry more efficient.

KSB offers five unique impeller designs that are specifically can be effective against Just as one tire doesn’t work for every car, no one engineered to handle different types of sewage. all types of sewage impeller can handle every type of sewage.

For cutting, the edges of the impeller need to be hard and sharp. Just like a knife in your kitchen, the blade blunts after a while. When sand and grit go through an open impeller, it becomes vulnerable to premature and rapid wear. The particles get lodged between the CHROME makes the KSB impellers are made of cast iron and will never wear out because wear rings causing damage. impeller harder there is no cutting involved in the process. All this affects efficiency and pump performance.
