• Novel diagonal-flow feed channel e entsoe bakeng sa likarolo tsa RO membrane.
• Ts'ebetso ea membrane element e ile ea matlafatsoa ka phallo e phahameng le ho hana letsoai.
• Mocha oa phepelo oa diagonal-flow o ka khothaletsa phetiso ea bongata le ho fokotsa sekhahla sa lera.
• Mocha oa phepelo oa diagonal-flow oa tšepisa ha phallo ea metsi le sekhahla sa ho hlaphoheloa li phahame.
