PhreeqPython is an object oriented wrapper around the (VIPhreeqc) extension of the Phreeqc chemical calculation engine (Parkhurst&Appello), written in Python.
PhreeqPython greatly simplifies adding solutions and querying their properties:
pp = PhreeqPython()
# add a solution consisting of 1 mmol CaCl2 and 2 mmol NaHCO3
solution = pp.add_solution_simple({'CaCl2':1.0,'NaHCO3':2.0})
print(solution.pH) # 8.12
print(solution.sc) # 427.32
print(solution.si('Calcite')) # 0.38
print(solution.species['HCO3-']) # 0.0019
print(solution.elements['Cl']) # 0.002 molAllows for simple chemical and precipitation/dissolution reactions:
solution.add('NaOH',0.5)
print(solution.pH) # 9.47
solution.desaturate('Calcite') # desaturate to SI 0
print(solution.total('Ca')) # 0.497 mmolAnd even allows for addition, devision and multiplication of solutions to form new mixtures:
solution2 = pp.add_solution_simple({'KCl':1.0})
# create mixture of 50% solution and 50% solution2
solution3 = solution * 0.5 + solution2 * 0.5
print(solution3.total('K','mol')) # 0.0005 molFor more examples, take a look at the examples folder.

This project makes use of the (Phreeqc) (David Parkhurst & Tony Apello) calcution engine and is (partly) derived from the (PhreeqPy) extension for IPhreeqc (Mike Müller)
Vitens is the largest drinking water company in The Netherlands. We deliver top quality drinking water to 5.6 million people and companies in the provinces Flevoland, Fryslân, Gelderland, Utrecht and Overijssel and some municipalities in Drenthe and Noord-Holland. Annually we deliver 350 million m³ water with 1,400 employees, 100 water treatment works and 49,000 kilometres of water mains.
One of our main focus points is using advanced water quality, quantity and hydraulics models to further improve and optimize our treatment and distribution processes.
