Datasheet entry items: explanation and examples

< Wastewater treatment facility identification >

(1)	Facility name : Name and the type of facilities
	(example) A city’s wastewater treatment plant
(2)	Facility location: Name of city, town and province
	(example) A town, B province

< Facility overview >

(3)	Operating period: Startup month and year if the facility is now in operation.
	(example) 4 years (since April, 2001)
	(example) 7 years (1988 ~ 1995)
(4)	Wastewater characteristics:
	• Domestic wastewater
	(example) household wastewater, night soil
	• Industrial wastewater
	(example) wastewater from dye factory, from food processing factory
	• Ambient water
	(example) Lake, pond, river, canals
(5)	Treatment process: Common name of treatment process. If the treatment process is new and less common, its characteristics and mechanism is summarized in remarks.
	(example 1) Conventional activated sludge process
	(example 2 ) Chemical precipitation and sand filtration
(6)	Process flow diagram: Show the flow diagram as well as sketch, and photographs.
	(example)
(7)	Specification of reactors/ equipment: Specification (volume, dimensions) of reactors/ tanks, and main equipment
	(example) Surface loading rate: m³/m²/day. Retention time: hr. (example) Oxidation pong: m³. Facultative pond: m³. Sedimentation pond: ** m³. (example) Oxidation ditch: length 30m, width 5m, depth 2m.

< Facility operation status >
Daily amount of treated wastewater: [m³/day]

(8)	Actual: Annual average daily flow. Comment in case of daily maximum or seasonal trend.
	(example) 200 m³/day (maximum daily flow. 300 m³/day)
(9)	Designed: Same as the actual.

Annual electric consumption: [kWh] Specify the period of time.

(10)	Actual:
	(example) 3,600 kWh (example) 4,200 kWh (monthly)
(11)	Designed: Same as the actual.

Annual amount of sludge generation: [DSt] Specify with the dry solid base.

(12)	Actual: Annual average daily flow. Comment in case of daily maximum or seasonal trend.
	(example) 6,000 DSt The data provided with the volume base can be converted to the weight base as shown below. (calculationexample) • data: 300,000 m³/year (water content 98%) • density: approximate 1,000 kg/ m³ • dry solid: 300,000 m³ × 1,000 kg/m³ × (100-98)/100 = 6,000,000 kg (= 6,000 DSt )
(13)	Designed: Same as the actual.

< Water Quality >
Process performance (Influent & effluent water quality):

Enter all water quality items which are required to remove in accordance with the effluent standard.
In addition to SS, BOD, COD, T-N, T-P and coliforms, enter other quality items if available.
Indicate the specific method if used for the water quality tests.
For COD, please circle the method of Cr or Mn.
(example) COD (Cr, Mn) (Potassium dichromate method)
(example) COD (Cr, Mn) (Potassium dichromate method)

Designed

(14)	Inlet quality: Designed inlet wastewater quality
(15)	Effluent quality: Designed effluent quality based on the standard.
	(example) COD_Cr < 50 mg/L
(16)	Performance: Designed removal ratio
	(example) BOD removal rate over 90%

Actual

(17)	Inlet quality: Explain the time period of average calculation; daily, monthly, or annually.
(18)	Effluent quality: Same as the designed.
	(example) SS 10mg/L (average of FY2003)
(19)	Performance: Calculate the removal ratio using the inlet and effluent water qualities, if both data are avilable.

< Operation & Maintenance >

(20)	Chemical consumption: Annual amount of chemical compounds such as coagulants, using for the wastewater and sludge treatment.
	(example) Coagulant PAC 36 ton/ year (Injection ratio: x[mg/L])
(21)	O & M personnel: Enter the number of O&M persons.
	(example) 2 resident operator. (example) Automatic operation and monitored by 1 patroller twice a week.
(22)	Remarks: Provide useful information such as facility establishment background, circumstances of surrounding waters of the treatment facility, and son on.
	(example) To comply with Wastewater quality standards and to conserve the water quality of public water bodies.

< Other >

(23)	Capital cost: Add the explanation of the counted items.
	(example) 60 million JPY, including only machinery and equipment. (example) 30 million USD, during construction in the middle of 80s.
(24)	Facility management body: Enter their homepage address if available.
	(example) Environmental Planning Bureau, City of Yokohama http://www.city.yokohama.jp/me/kankyou/gesui/index.html
(25)	Manufacture/ designer: Indicate the homepage address of the manufacture/ designer.
