Water supply with reverse osmosis purification system, used for plant cultivation, includes buffer for storing brine until it can be mixed with rainwater and disposed of

摘要

The salt-rich aqueous fraction obtained from the reverse osmosis step is temporarily stored in a buffer (5) and then later mixed with other water, e.g. rainwater, in order to obtain irrigation water having a suitable salt concentration or composition allowing it to be safely disposed of via the soil, drains or surface water.
