SUMMARY

The discussion focuses on calculating the daily throughput of a reverse osmosis plant necessary to supply 4.5 million liters of drinking water per day, with a minimum total hardness of 60 mg l-1 as Ca. The feed water has a total hardness of 660 mg l-1 as CaCO3, while the permeate hardness is reduced to 4 mg l-1. The participant seeks guidance on breaking down CaCO3 into its constituents to facilitate the calculations required for this problem.

PREREQUISITES
  • Understanding of reverse osmosis processes
  • Basic chemistry knowledge, specifically regarding calcium carbonate (CaCO3)
  • Familiarity with water hardness measurements
  • Ability to perform unit conversions and calculations
NEXT STEPS
  • Research the principles of reverse osmosis and its efficiency
  • Learn about water hardness and its impact on drinking water quality
  • Study the chemical breakdown of calcium carbonate (CaCO3) into calcium ions (Ca2+) and carbonate ions (CO32-)
  • Explore methods for calculating water throughput in filtration systems
USEFUL FOR

Students in environmental science, water treatment professionals, and anyone involved in water quality management will benefit from this discussion.

Homework Statement



in order for a well to supply 4.5 million litres of drinking water per day, at a minimum total hardness of 60mg l-1 as Ca, calculate the daily throughput of the reverse osmosis plant assuming that 30% of the feed to the plant comes out as reject.

Homework Equations



a table provides the following info:
total hardness (as mgl-1 CaCO3) at feed is 660 but at permeate it is 4

The Attempt at a Solution



i suspect i must break down CaCO3 into its constituents however i can't remember how to do this. Iwould be very grateful for a pointer in the right direction.

guys I am only a newbie to both the sciences and this great website, I am not looking for an exact answer but just a clue of how to tackle this question. if any further questions is needed please reply, i really am going off my head trying to get over this mental block I am having.
 
Perhaps you should post this under the "Other Sciences" sub-forum, also under Homework & Coursework Questions
