Installation of the return osmosis of the third degree working on permiats of installations of the return osmosis of the first and second stages

The durability of the equipment directly depends on the quality of the supplied water. Our Customer has a need to obtain over purified water with a minimum content of salts or their complete absence.

The specialists of our company have designed and manufactured a reverse osmosis unit of the third degree, which works on the remittances of reverse osmosis of the first (on artesian water) and second (on concentrate from artesian water) stages.

Permeate from existing reverse osmosis units by means of pumps with frequency converters is fed to the reverse osmosis unit of the third stage. При цьому, у вхідний потік дозується розчин реагенту для підняття рівня pH і переведення розчинного вуглекислого газу в гідрокарбонат-іон, в результаті чого отримуємо 16,7 м ^%./год води з електропровідністю менше ніж 3 мкСм/см та відбором пермеату (recovery) 82 – 85 %.

To control the operation of the installation, an extension of the existing control cabinet based on the SIMENS industrial controller is provided
