Photovoltaic wastewater mainly comes from silicon rods in the process of cutting, grinding, slicing and silicon wafers in the process of grinding, corrosion, polishing and other auxiliary wastewater and cleaning wastewater, and its treatment difficulties mainly include: organics (mainly polyethylene glycol, etc.), suspended solids (mainly silica powder, silicon carbide) with high concentration, and contains fluoride ions and acids and alkalis (mainly hydrofluoric acid, nitric acid and other buffer acids) and other pollutants. Photovoltaic glass production mainly produces salt-containing mixed wastewater 90m3/h, which enters the salt-containing wastewater treatment system, the produced water meets the requirements of reuse for reuse, and the concentrated water is discharged to the sewage network.
Pump supporting: photovoltaic glass salt wastewater treatment project
Project customer: a glass chemical company
Actual flow: 90m3/h
Actual head: 9m
Water body analysis: salt-containing mixed wastewater, three per cent hydrofluoric acid
Temperature of water body：80℃
Structure form: centrifugal
Application process: saline wastewater conveying and lifting
Customer requirements: a certain degree of self-priming ability, pressure 2kg
Medium concentration: 40% sodium chloride, 3% hydrofluoric acid
1、Confirm the pump type
According to the customer site process to determine the type of pump: customers need to use the pump in the saline wastewater transfer and enhancement, first of all, we can determine that our pumps can be used: Mabel MK acid and alkali self-priming pumps, MIT/MD acid and alkali vertical pumps, MS/MSH
acid and alkali resistant magnetic pumps and MC acid and alkali resistant chemical pumps.
2、Determine the pump material
According to the type of media, temperature, concentration to determine the pump material: customer site water is mainly: salt-containing mixed wastewater (ph = 7); temperature of 80 ℃, the main medium for forty per cent of sodium chloride, three per cent of hydrofluoric acid.
According to the medium of PH acidity, temperature and concentration, we recommend the customer pump material selection: PVDF.
3, determine the power of the pump
According to the actual head flow to determine the power of the pump: the customer needs the actual head of the pump 9M, the actual capacity of 90m³/h, so we recommend the pump power: 11KW.
4、Determine the specific model
According to the customer's other requirements to determine the specific model: the customer requires the pump has a certain self-priming ability, the export pressure of 2 kg. Combined with the material, power, process, we recommend to the customer: MC acid and alkali chemical pumps (with water storage tank). Specific model: MCP-100151VH-SSH, material: PVDF, power: 11KW.
Mabel environmental protection is a modern large-scale manufacturing enterprise dedicated to the development, design, production and sales of corrosion-resistant pumps and electroplating filters. Production of acid and alkali self-priming pumps, acid and alkali vertical pumps, acid and alkali magnetic pumps, dosing pumps, electroplating filters and so on.
