The lack of success in developing adequate water quality standards programs, along withgrowing concern about the environment, prompted the President to form the United StatesEnvironmental Protection Agency (EPA) in 1970 to enforce environmental compliance andconsolidate federal pollution control activities. The Refuse Act Permit Program (RAPP) wasdeveloped, under the 1899 Rivers and Harbors Act, as a new permitting program to controlwater pollution. RAPP required any facility discharging wastes into public waterways to obtain afederal permit specifying abatement requirements from the Army Corps of Engineers. TheAdministrator of the EPA endorsed the joint program with the Corps of Engineers, and onDecember 23, 1970, the permit program was mandated through Presidential Order. EPA and theCorps rapidly began to prepare the administrative and technical requirements for the permitprogram, but the effluent limits were more or less arbitrarily determined. In December 1971,RAPP was struck down by a decision of the Federal District Court in Ohio (Kalur vs. Resor).

What is reverse osmosis?
Reverse Osmosis (RO) technology removes dissolved solids and impurities from water by using a semi-permeable membrane, which allows the passage of water but leaves the majority of dissolved solids/salts and other contaminants behind. The RO membranes require a greater-than-osmotic pressure and high-pressure water to achieve the desired result. The water that passes through the RO membrane is called the permeate, and the dissolved salts that are rejected by the RO membrane are called the concentrate.

What is a permit for a facility?
permit is typically a license for a facility to discharge a specified amount of a pollutant into areceiving water under certain conditions ; however, permits may also authorize facilities toprocess, incinerate, landfill, or beneficially use sewage sludge. The two basic types of NPDESpermits issued are individual and general permits.
What is NPDES permit?
Title IV, Permits and Licenses, of the FWPCA Act created the system for permitting wastewaterdischarges (Section 402), known as the National Pollutant Discharge Elimination System(NPDES). Under NPDES, all facilities which discharge pollutants from any point source intowaters of the United States are required to obtain a permit. The permit provides two levels ofcontrol: technology-based limits (based on the ability of dischargers in the same industrialcategory to treat wastewater) and water quality-based limits (if technology-based limits are notsufficient to provide protection of the water body).
What is a municipal POTW?
Municipal sources are POTWs that receive primarily domestic sewage from residential andcommercial customers. Larger POTWs will also typically receive and treat wastewater fromindustrial facilities (indirect dischargers) connected to the POTW sewerage system. The types ofpollutants treated by a POTW will always include conventional pollutants, and may includenon-conventional pollutants and toxic pollutants depending on the unique characteristics of thecommercial and industrial sources discharging to the POTW.
What are the three categories of pollutants?
For regulatorypurposes, pollutants have been grouped into three general categories under the NPDES Program:conventional, toxic , and non-conventional. There are five conventional pollutants (mentionedabove and defined in Section 304(a)(4) of the CWA). Toxic pollutants, or priority pollutants,are those defined in Section 307(a)(1) of the CWA and include metals and manmade organiccompounds. Non-conventional pollutants are those which do not fall under either of the abovecategories, and include such parameters as ammonia, nitrogen, phosphorus, chemical oxygendemand (COD), and whole effluent toxicity (WET).
How much of the nation's water was safe for fishing and swimming?

Although testing is continuous throughout the wastewater treatment process to ensure optimal water flow, clarification and aeration, final testing is done to make sure the effluent leaving the plant meets permit specifications.
What is the process of removing large items from the influent?
Removal of large items from the influent to prevent damage to the facility’s pumps, valves and other equipment .#N#The process of treating and reclaiming water from wastewater (any water that has been used in homes, such as flushing toilets, washing dishes, or bathing, and some water from industrial use and storm sewers) starts with the expectation that after it is treated it will be clean enough to reenter the environment.#N#The quality of the water is dictated by the Environmental Protection Agency (EPA) and the Clean Water Act, and wastewater facilities operate to specified permits by National Pollutant Discharge Elimination System (NPDES). According to the EPA, The Clean Water Act (CWA) establishes the basic structure for regulating discharges of pollutants into the waters of the United States and regulating quality standards for surface waters. Under the CWA, EPA sets wastewater standards for industry. The EPA has also developed national water quality criteria recommendations for pollutants in surface waters. EPA's National Pollutant Discharge Elimination System (NPDES) permit program controls discharges.#N#As an example of expected standards, the Biochemical Oxygen Demand (BOD) of average wastewater effluent is 200 mg/L and the effluent after treatment is expected to be >30 mg/L. It is crucial a wastewater facility meets these expectations or risk stiff penalty.#N#The physical process of wastewater treatment begins with screening out large items that have found their way into the sewer system, and if not removed, can damage pumps and impede water flow. A bar screen is usually used to remove large items from the influent and ultimately taken to a landfill.
What is activated sludge?
These small solids are called activated sludge and consist mostly of active bacteria. Part of this activated sludge is returned to the aeration tank to increase the bacterial concentration, help in propagation, and accelerate the breakdown of organic material. The excess is discarded.
What is the function of an aeration tank?
The primary function of the aeration tank is to pump oxygen into the tank to encourage the breakdown of any organic material (and the growth of the bacteria), as well as ensure there is enough time for the organic material to be broken down.
What is a bar screen in wastewater treatment?
A bar screen is usually used to remove large items from ...
Why is wastewater pumped into a secondary clarifier?
Treated wastewater is pumped into a secondary clarifier to allow any remaining organic sediment to settle out of treated water flow. As the influent exits the aeration process, it flows into a secondary clarifier where, like the primary clarifier, any very small solids (or fines) sink to the bottom of the tank.
Where do organics sink in a clarifier?
Solids known as organics/sludge sink to the bottom of the tank and are pumped to a sludge digestor or sludge processing area, dried and hauled away. Proper settling rates are a key indicator for how well the clarifier is operating.
