According to the requirements of Party A, this design plan - IWP water purification equipment is formulated.

The equipment integrates the removal of BOD, COD, NH4+-N, and TN, and is currently a high-efficiency and energy-saving sewage treatment device. It has been proved by practical application that IWP water purification equipment is a kind of equipment with ideal treatment effect, high degree of automation, simple operation and convenient maintenance and management.

Scope of supply: The lifting pipeline of the submersible sewage pump of the regulating tank enters the integrated equipment, and it ends when the water is discharged from the secondary sedimentation tank and ends in the clear water tank. It includes process equipment, electrical, installation and commissioning, (boundary area: 1 meter around the integrated equipment).

Table for influent and effluent values
No.	Parameter	Inflow to screen chamber	Discharge Values	Unit in mg/lt	Remarks
1	BOD	<300	<20	mg/L	MBR Expected Less than Discharge level
2	COD	450	60	mg/L
3	TSS	<350	<30	mg/L	MBR Expected Less than Discharge level
4	TN	40	10	mg/L
5	Ammonia in NH3-N	25	5	mg/L
6	TP	20	2	mg/L
7	Grease	15	2	mg/L	A maintenance schedule should be followed for grease trap upfront of the screen. The grease trap should be sized by a hydraulics engineer.
