Solution
The pump of Shunzi Machinery has the following advantages in the measurement of phosphate precipitation agent in the water treatment process:
Precipitating agent accurately measured (iron chloride (III))
The pump can be started absolutely reliably from any operating state-there is no need to position the diaphragm
The tightness of the pump prevents the leakage of extremely corrosive precipitation agent
Patented sandwich diaphragm with diaphragm protection system DPS (diaphragm protection system) and diaphragm monitoring
The integrated pressure relief valve protects the pump from overpressure (pressure shock/water hammer), which may cause damage to the pump or pipeline.
A sandwich diaphragm with the lowest life cycle cost due to high energy efficiency, low maintenance cost and extremely long service life
Maximum reliability and availability, even under operational errors or under extreme operating conditions (such as closed pressure lines or suction lines)
Due to the safe operation and low energy consumption, it is beneficial to environmental protection
Background
What happens when phosphate precipitates?
The precipitation of methyl phosphate is a physical-chemical reaction in which phosphate and trivalent metal salt are precipitated. Use non-hazardous iron (III) and aluminum salts at the same time. When metal salts are introduced, positively charged metal ions are formed, and they react with negative phosphate ions. The resulting insoluble metal phosphate precipitates out in the form of flocs.
The precipitant must be quickly introduced at the corresponding location so that the ions can fully react with each other. This is followed by a flocculation stage, during which fine precipitates can aggregate to form precipitated flocs.
