Glass Processing Wastewater Recycling System Professional Customization
6.5 Glass processing wastewater recycling system
Background:
The glass industry is an important industry in most countries' industries and plays a very important role in the country's economic construction. With the rapid economic growth of various countries, the industrialization and urbanization process has accelerated, and the demand for construction glass, automotive glass and glass products has increased greatly. It has created a great space for the development of the glass industry, so glass will generate a large amount of wastewater to be processed in the processing and production engineering.

2) Process Description:
The raw water enters the wastewater regulating tank through the coarse filtration of the grid, and is adjusted and upgraded by the professional lifting pump of the wastewater into the dosing reaction tank. The turbidity and pH value of the measuring water are fed back, and the metering pump is automatically added.
Aluminum hydroxide (PAC) and polyacrylamide (PAM) flocculate and precipitate, add sodium hydroxide (NaoH) to adjust the pH value, the mixed solution after the reaction enters the sedimentation tank for precipitation, and the supernatant after sedimentation flows into the dissolved gas.
The floater, while the settled sludge enters the sludge tank. Adding polyaluminum hydroxide (PAC) and polyacrylamide (PAM) to the dissolved air flotation machine, the remaining impurities in the water that have not been disposed of in the previous period, and the particles in the dissolved air flotation machine generate a large amount of bubble removal by air flotation, and These impurities and particles will enter the sludge pool.
The sludge from the sludge tank and the sludge naturally precipitated from other words are pumped into the cake by a gravity flow or sludge pump and pressed into a cake to be periodically removed. The source water treated by the dissolved air flotation machine will enter the sand filter tank, further precipitate and filter, and then flow into the clear water tank, which can be used in the production line.

4) Advantages: stable operation of equipment, excellent effluent quality, low operating cost and small floor space. The operation is simple and the return period is short.
Supply (cooperation) mode and delivery cycle
1: Determine the usage scenario.
2: Analyze the quality of contaminated water (if necessary, do laboratory analysis)
3: Determine the treatment process.
4: The supplier forecasts the price duration and governance objectives of the equipment or system.
5: The supplier and the buyer negotiate the price duration and the governance objectives, negotiate the contract, and sign the contract and pay the supplier prepayment.
6: After the equipment is produced and paid by the buyer and its agent, the payment will be made.
7: The supplier rushed to the place of use of the buyer for installation instructions and commissioning.
8: System training for equipment use and maintenance.
