Process Description
The wastewater from the washing line is first discharged to the wastewater collection pool for collection and temporary storage;
Step 1: the wastewater conveyor to the vibrating screen for solid-liquid separation by the water pump, the larger particles into the slag collection box, and the wastewater into the sedimentation tank;
Step 2: After the wastewater into the sedimentation tank, According to the online PH meter feedback date, automatically added acid and adjust the PH index to neutral, then added flocculant and coagulants to the flocculation reaction.
Most of the condensed flocs will sink, and the clear water will float up and into the air flotation tank to realize the separation of mud and water, and the mud water will be discharged to the sludge tank regularly;
Step 3:Clear water into the air flotation tank, and when compressed air is mixed with water, micro-bubbles are produced, The residual fine particles and the floating matter will float to the surface of the pool by the air bubbles, then, are discharged through the scraper device; After treatment the clean water into the water pool temporary storage.
Step 4: Clean water will be conveyor to the filter by the High-pressure pump and filtered water goes back to the washing line.
The sludge produced by the sedimentation tank and air flotation into the sludge tank, and dewatered by the sludge dewatering device and then transported out for treatment regularly.

2. Main Process Introduction:
a.Wastewater collection tank(prepared by customer)
It is mainly used to collect the cleaning wastewater discharged from the cleaning line, and also serves as the sump of the sewage lift pump, which has the functions of buffering the flow change, regulating the water volume, and homogenizing the water quality.
Design stay time:≮2h
Integrated waste water collection pool*1set,Effective volume:40m³

b.Lift pump
It is used to lift the sewage to the sedimentation tank for treatment. The design adopts non-blocking submersible sewage pump, which is easy to install and maintain, and has a long service life. The automatic start and stop can be realized through the level gauge set in the regulating tank, reducing manual operation.

c.Vibrating screen 
The circular vibrating screen is set at the forefront of the water treatment system, mainly to separate the larger particles in the discharged wastewater, which is beneficial to the subsequent sedimentation treatment and reduces the blockage and wear of subsequent equipment.
Main Materail:SUS304
304 collection box*1

d.Integrated sedimentation tank
The integrated sedimentation tank adopts inclined tube sedimentation tank, which is set at the front end of the treatment system. By adding acid, the PH of wastewater is adjusted to neutral, providing the best conditions for subsequent sedimentation reaction. In this process, the PH set in the reaction tank is interlocked with the acid dosing metering pump to realize the automatic adjustment of PH.
At the same time, by adding flocculants and coagulants, SS in the wastewater can be coagulated and settled, and mud and water can be separated by gravity, so as to clarify the water quality.
Processing capacity:20m³/h  1set
External dimensions:L11000*W2000*H3500
Material:Carbon steel + anti-corrosion
Mud discharge:The mud discharge valve is an electric valve, which automatically discharges mud regularly

Integrated sedimentation tank of Aceretech Water Treatment System

The wastewater after sedimentation treatment will still contain a small amount of floating substances, which need to enter the air flotation tank for further treatment. Air floatation is the dissolved water produced by the dissolved gas system, which is released into the water through rapid decompression to produce a large number of tiny bubbles. Several bubbles adhere to the suspended solids or oil surface in the water, forming suspended solids with an overall density of less than 1. The solid and liquid are separated by buoyancy to make the water completely clear.

g.Clean water pump
It is used to reuse the treated recycled water to the cleaning line. The design adopts vertical centrifugal pump, which is easy to install and maintain, and has a long service life. High level alarm and low level pump stop can be realized through the level gauge set in the regulating tank.
Qty.:2set(One for use, the other for backup)

The treated wastewater is deeply filtered and adopts quartz sand as the filter material, the water flows through the internal water distributor and water collector, and high-speed filtration is performed in the tank, which can effectively remove particulate matter and reduce turbidity.

i.Dosing System
The dosing device is composed of metering pump, reagent barrel, agitator, etc., and is used to realize the quantitative dosing of reagent. Among them, PAC is a flocculant with strong bridging adsorption performance, which can coagulate and adsorb with suspended solids in water, so as to destabilize and settle the suspended solids; Anionic PAM is a coagulant, which can be used in combination with flocculant to improve the sedimentation of flocs and facilitate the clarification of water quality; Cationic PAM is used for sludge dewatering, which is conducive to solid-liquid separation. The automatic acid dosing device is used to adjust the PH of wastewater to be neutral, and the automatic dosing is realized through the online PH device.
