Treatment Facility A local government may bring suit to enforce it's Rules Cities with more then ________________ population must have a water pollution control program 10000 Goals of TCEQ include maintaining water quality for public health, commercial use, and Wildlife Preservation TCEQ may revoke a license if the operator ____________ (2-6) 1.Violate the permit 2.Falsifies records 3.Neglects their duty 4.All the above When a accidental discharge, bypass, or spill occurs, the discharger must notify TCEQ within _____________ hours 24 An Administrative penalty can be up to ________________ per day $10000 Penalty assessments is based upon physical effect, intentions, responsibility, and ________________(2-7) Economics benefit accrued Penalties are levied for 1,Failure to submits reports 2.Bypasses 3.No discharge permit 4. All the above In each permit, the TCEQ sets conditions including permit duration, strength of the discharge, monitoring requirements, point of discharge, and _________________ of the discharge. (2-7) Quality State laws requires that self-reporting forms be complied and mailed each _________________ to TCEQ Month The authorized agent or ______________ must sign the report (2-7) ???????? Required records, such as flow and effluent quality must be kept at least ________________ years 3 True Because wastewater is mostly water, it weighs 8.34 Ibs./Gal. True labs report many characteristics of wastewater as milliliters per liter (ml/L) False (#4 radiological) wastewater characteristics are divided into 3 primary groups : Bacteriological, physical, and chemical. False ( Answer: Microscope) bacteria are seen with a telescope and are present in soil, water, air, decaying organic matter, and the intestinal tract of humans and animals. True Some bacteria cause disease and are called pathogens True one way to classify bacteria is by Oxygen use : aerobic, facultative, and anaerobic False Answer Oxygen Aerobic bacteria require dissolved, uncombined (free) Nitrogen Flase (Answer Dissolved) Anaerobic bacteria cannot live when chemically combined Oxygen is present TRue Facultative bacteria live with free oxygen or chemically combined Oxygen True Fresh domestic wastewater contains dissolved Oxygen False (Answer Disagreeable/ Lacks) Septic wastewater is dark, has agreeable odor, and contains dissolved Oxygen. False (Answer odorous) Septic Wastewater contains Fragrant gases produced by bacteria TRue Some chemical characteristics of wastewater include solid, grease, DO, pH and gases False (Answer doesn't include soft and hard solids Solids include total, suspended, dissolved, settable, inorganic, organic, and soft and hard solids. TRUE Suspended solids can be filtered out and dissolved solids pass through a filter True Settleable solids are dissolved solids of sufficient weight to settle when left standing for a time. True Inorganic material, suspended or dissolved, is sand, grit, and minerals True Two other classifications of solids are inorganic (ash) and organic (volatile) True The ash (fixed Solids) left after burning consists of inorganic solids True Organic solids are volatile, combustible solids found by burning the residue from the total solid test or the filter from the TSS test FALSE (Iron is not included) Examples of organic are sugar, butter, leather, paper, and iron The three primary organics are _______________, proteins, and grease Carbohydrates ___________________ in raw wastewater comes from the water supply Dissolved oxygen When dissolved oxygen is present, it indicates the wastewater is Fresh As the water temperatures rises, the DO saturation level will Decrease (inverse effect) The dissolved oxygen test must be performed as soon as a sample is taken because Oxygen levels can ______________ change Quickly The ________________ test measures the oxygen depleting effect of the wastewater upon the receiving stream. BOD The BOD test indicates wastwater Strength The BOD test measures Oxygen consumed as organics are oxidized by biological and chemical action during incubation for __________________ days at ____________________ Celsius. 5/20 Each person contributes about _______________________ Ibs of BOD daily 0.17 The pH scale ranges from ________________ to ____________________ with 7 being neutral 0/14 ___________________ water has a pH below 7.0 while ___________________ water has a pH above 7.0 Acidic/ basic Dangerous gases produced during the breakdown of organics in wastewater are Hydrogen Sulfide, carbon dioxide, and ___________________. Methane The __________________ Decomposition of organic matter produces methane which is colorless. 1.Aerobic 2.Facultative 3.Anaerobic listed Hydrogen sulfide has a ___________________ odor, is a combustible in air, and is very toxic Rotten egg _____________________ is odorless, colorless, heavier than air, and not combustible. Carbon dioxide (suffocating) Grid sampling results depends on _________________ 1. Ensuring the sample represents the waste stream 2. Using proper sampling technique 3. Preserving the sample until analyzed 4, all listed Select a point where ______________________ is thorough and the wastewater quality is uniform Mixing A ______________________ sample is collected at any point, at any time Grab When a sample of a plant unit influential is collected at any time and a sample if the effluent is collected corresponding to the units detention time, the sample is a Timed grab Domestic waste uniform in content False ( is not uniform in content) Some waste cannot be treated in a domestic wastewater treatment plant because the waste would harm the biological process or contaiminate the waste sludge True (think of oil and gas) Sources of wastewater include domestic, I & I, food processing, agricultural operations, and industrial operations. True By weight, domestic wastewater is about 99.9% water and 1% solids. False ( answer 0.1%) Flows from domestic sources average about 100 gallons/day per person True Inflow is stormwater that enters a collection system through openings such as house wastewater, line cleanouts or open manholes. False ( Answer house wastewater is waste water) ( 2 reason has to be broken line cleanouts) Infiltration is stormwater that enters the collection system through broken pipe joints, manhole walls, and cracked pipes.
